VoL. XXXII February, 1937 No. i



By Geo. P. Engelhardt, Hartsdale, N. Y.

The accompanying illustration portrays an entomologist to whom much credit is due for the success and growth of the Brooklyn Entomological Society, following its reorganization in 1900.

Born in New York City and educated at the Greyback Seminary and Williams College, R. P. Dow joined his father’s firm as a broker. Subsequently he became financial editor of the Commercial

2 Bulletin of the Brooklyn Entomological Society Vol. XXXII

Advertiser and in 1905 established himself in a security business, continuing until his retirement and removal to California in 1918.

Those who have known R. P. Dow will remember him as an in- dividual of unusual personality. Tall, slender, with flowing mus- taches, a broad-rimmed hat at a rakish angle, he always was at ease, personifying his background of long American ancestry and of culture. With a leaning to classical literature and art, expanded on sojourns in Mediterranean countries, he combined a lifelong inter- est in the natural sciences. He had hobbies of various kinds and played them hard. He was an enthusiastic golfer, loved chess and was a founder of the Brooklyn Chess Club and a promoter of the annual international cable chess match. For nature in all its phases he had an inborn appreciation. Collections of butterflies and moths, started in boyhood, are still cared for and cherished by his sister, Miss Susan, at the Dow homestead in Claremont, N. H.

With such inclinations it needed only contacts made at the Brook- lyn and at the New York Entomological Societies to set ablaze an ambition to make a name for himself in the entomological world. He became a member of both societies and in a remarkably short time acquired a very notable collection of Coleoptera, in large part by personal collecting. Long-neglected field meetings, under his leadership, resumed unsurpassed activity, bringing out at times 25 or more members, some even from the societies of Newark and Philadelphia. Such gatherings, arriving or departing from railroad stations were apt to arouse the curiosity and astonishment of on- lookers. Dressed in old clothes, battered hats, long boots or puttees and carrying all sorts of queer-looking collecting paraphernalia, it certainly was an odd-looking assemblage. Dow in the vanguard, utterly oblivious of public impressions, carried the eight-foot pole of his butterfly net across the shoulder, the three-foot bag hanging behind and the rest of the party straggling along. He loved to repeat the remark of a bystander, overheard on a trip to Overbrook, N. J., a place noted for the insane asylum on top of a hill above the railroad station. “There goes a bunch of lunatics,” was the remark.

The Bulletin of the Brooklyn Entomological Society more than doubled in volume, as well as in circulation, during Mr. Dow’s editorship, 1915-1918. His contributions to entomological literature, it will be noted from the titles of the appended list, are more in the nature of historical reviews and philosophical contem- plations, than pure research. Leng’s Catalogue of the Coleoptera cites only one beetle named by him : Cicindela ohsoleta form anita. His collection, ultimately, was acquired by Wm. T. Davis. His papers, usually read before publication at the Brooklyn or at the

Bulletin of the Brooklyn Entomological Society 3

New York society, always were anticipated with interest. His de- livery was slow, droll, interspersed with drawls and chuckles, im- parting to his audience his own enjoyment of the occasion, as well as his keen sense of humor. In these days, when entomological meetings have become so cut and dried, one misses the stimulation of a man like Dow. The niche, so peculiarly his own, has not been filled.

In California, R. P. Dow roamed for a spell, doing little, if any, entomological work. Then he built himself a home. Like a swal- low’s nest under the eaves of a precipice it nestled high up against a steep hillside overlooking picturesque Laguna Beach and the boundless ocean beyond. He had a flower garden and orchard trees, a lily pond and animal friends of all sorts, furry, feathered and scaly, which fed out of his hand. Much of his time was con- sumed in writing the genealogy of the clan of the Dows. A tre- mendous job, judging by his mansucript stacked several feet high. Not all of the Dow ancestors came to a peaceful end. This was a source of especial satisfaction to him. The genealogy appeared in book form not long ago.

On a visit late this summer we found R. P. Dow in a hospital, a very sick man. The end was near and he knew it. Was he down- hearted, discouraged? Not a bit. His life had been full to the brim. Pleasures, sorrows, accomplishments, he had them all in full measure. What more could be asked for? On November nth he passed away, peacefully, content.

On our records let us inscribe his characteristic message: ‘‘Yours fideliter, R. P. Dow.”

“Torre! Torre! Torre! You never use one word where two would do as well !” And the heartless blue pencil would tear through some fruity expression.

What Dow said about absent authors when he read their best efforts and ruthlessly slaughtered them, only the Recording Angel knows and I hope he lost his pencil !

Surrounded by his books, his collection^, by serried ranks of sets of the Bulletin and cabinets and safe containing his business data, Dow sat enthroned at his desk, flanked by a typewriter as a guard of honor. There, in his little office in the old Mills Building, in the very center of the financial ganglion of New York, he elaborated those fascinating jeux d' esprit about The Testimony of the Tombs, The Brood of Lilith. Here, his imagination, enriched by much esoteric reading, led him into curious byways of entomology.

And so I knew Dow caustic, kindly, “full of strange oaths and bearded like a pard.”

And he is now gone into the great certitude !

, Withal, Robert Percy Dow was a MAN.

brethes and rhinonitela williams


By V. S. L. Pate, Ithaca, N. Y.

During the past summer of 1936 at Woodhaven, Long Island, Mr. William George Bodenstein discovered a number of small aculeates nesting in the trunk of a dead cherry tree in the yard of his neighbor, Mr. J. C. Linz. Upon examination these were found to be Stigmus americanus Packard, Trypoxylon frigidum Smith, and a new species of the rather rare genus Nitela which is described herewith, bringing the number of Nearctic species of this genus now known to three. Hovering about the nesting holes in the dead cherry tree, Mr. Bodenstein informs me, were a number of the small parasitic Chrysid wasp, Chrysidea verticalis Patton.

Nitela cerasicola n. sp.^

2. 4 mm. long. Entirely black, except the apices of the

mandibles which are dark red, and the tibial spurs which are testaceous. Clothed with a sparse, pale, short pubescence.

Wings clear hyaline, veins dark brown; forewing with the submarginal cell subrectangular, twice as long as broad, the recurrent nervure received by the cubitus distinctly before the transverse cubital nervure, the cubitus prolonged beyond the transverse cubital nervure as a short but distinct spur; mar- ginal cell narrowly rounded apically and weakly appendiculate there.

Head shining to subopaque, face, clypeus and vertex closely and finely punctate, temples aciculate; clypeus rounded out and with a shining, impunctate subbevelate portion medio- apically, laterad of which on each side is a blunt tooth ; clypeus and front for the length of the scape with a cristate median longitudinal keel on each side of which there is a rather deep concave scapal basin; antennal insertions about twice as far from each other as from the nearest eye margin, pedicel as long as the first segment of flagellum, second and third flagel- lar articles subequal in length to the first and individually longer than any of the succeeding flagellar segments ; eyes con- vergent toward the vertex and very finely and obscurely pu- berulent ; mandibles entire beneath, simple apically ; malar

^ From cerasus, cherry tree, and colo, to inhabit, in allusion to its nesting habits.

space evident, about one-third the length of the scape ; ocelloc- ular line about one-third the postocellar line.

Thorax shining, with puncturation similar to that of face; pronotum rounded anteriorly, not transversely carinate, dorsal surface with a deep transverse, minutely foveolate sulcus in- terrupted medially by a raised V-shaped backward production of the anterior dorsal surface; mesonotum with the lateral edges margined with a row of small foveolae, but the anterior lateral corners without trigonal foveolate areas as in N. vir- giniensis, the posterior margin with a distinct row of foveolae ; mesopleura with the episternal suture, the sternauli, and an impressed furrow just before and parallel to the meso-meta- pleural suture foveolate, the prepectus and mesosternum sub- opaque, and finely punctate, the mesopleura behind the epister- nal suture and above the sternauli shining, polished and im- punctate, discally with a deep median pit; metapleura anky- losed with the propodeum and shining, highly polished and im- punctate; propodeum shining, the dorsal face traversed by well separated, parallel longitudinal carinulae connected irregu- larly with one another by transverse carinulae; lateral faces of propodeum with irregular parallel longitudinal carinulae; posterior face minutely irregularly clathrately rugulose, medi- ally with a narrow, deep elongate subobcuneate fovea, laterally at the junction with the lateral faces, carinate.

Abdomen shining, highly polished, and with a very fine scattered puncturation ; pygidial area wanting.

J'. Unknown.

Holotype. 8720 Ninety-sixth Street, Woodhaven, Long Island, New York, August 29, 1936 (W. G. Bodenstein; nesting in trunk of dead cherry tree).

This species seems to be somewhat intermediate between Nitela virginiensis Rohwer and N. floridana Pate, agreeing with the latter by possessing an elongate subrectangular submarginal cell and- in the finely puberulent eyes but differing from it by the transversely sulcate pronotum, the sculpturing of the head and thorax, and the color of the legs. On the other hand, the general habitus of N. cerasicola is quite similar to N. virginiensis but the pronotum is not transversely carinate as in the species, nor does the mesonotum have the anterior lateral corners provided with a trigonal foveolate area and the hind margin medially with a radiating fan of carinulae that are so characteristic of V. virginiensis.

Until further material is forthcoming, the following key will serve to distinguish the known Nearctic species of Nitela. As yet.

Bulletin of the Brooklyn Entomological Society 7

no males are known, but they should be separable upon the charac- ters given below.

1. Pronotum transversely carinate anteriorly; mesonotum at each

anterior lateral corner with a trigonal foveolate area, posterior margin medially with a fan of radiating carinulae ; eyes bare ; submarginal cell rhomboidal virginiensis Rohwer.

Pronotum rounded anteriorly, not transversely carinate; meso- notum not so constructed; eyes microscopically puberulent; submarginal cell rectangular 2

2. Pronotum flat dorsally, not transversely sulcate; mesonotum

with posterior margin simple, not foveolate; head and thorax microscopically shagreened; clypeus and front not keeled; cubitus of fore wing without a stump distally; legs fulvous; southern species fioridana Pate.

Pronotum with a transverse, minutely foveolate sulcus dorsally; mesonotum with posterior margin foveolate ; head and thorax finely punctate; clypeus, and front with a median longitudinal cristate keel; cubitus of fore wing with a stump distally; legs

black; northern species

cerasicola n. sp.

In 1928 Williams established the genus Rhinonitela^ for the re- ception of two species from the Philippines and British Guiana, differentiating it from Nitela by the presence of a median longitu- dinal cristate keel on the clypeus and front, by the mandibles being simple and edentate apically, and by the eyes being hairy. His diagnosis, however, agrees very well with Ducke’s description of Nitela amazonica^ upon which Brethes in 1913 based his genus Tenilaf^ and although I have seen no authentic material of either of these, I believe that the two groups are congeneric in all probability. Nitela cerasicola and, in some measure, N. fioridana apparently ex- hibit the characteristics of this genus, and if they should eventually prove to be congeneric with Tenila, I do not think that this group may be accorded the rank of a discrete genus indeed, it is doubt- ful if Tenila may even be considered a good subgenus. However, until I have had an opportunity to examine material of Tenila and Rhinonitela, I am unable to settle this question satisfactorily. For the present, consequently, I prefer to allocate cerasicola and fiori- dana to Nitela.

By L. L. Pechuman, Cornell University, Ithaca, New York.

In the course of work on the Dutch Elm Disease conducted by the Departments of Entomology and Plant Pathology at Cornell University, it was thought advisable to make a rather complete study of the various species of insects found in elm with especial reference to their potential ability to transmit the organism of the Dutch Elm Disease.

This work was begun in 1934 by Dr. P. A. Readio and has con- tinued under his direction and later that of Dr. D. L. Collins until the present time. Mr. Henry Dietrich and Mr. C. H. Martin have also made numerous observations on elm insects. This paper is, therefore, more or less a compilation of observations made by all members of the Dutch Elm Disease Investigation staff, and all should receive equal credit.

In addition to field collections many samples of elm wood were collected both within and without the Dutch Elm Disease area. These samples were caged and a record kept of all emergence from each sample. In this way much ecological and biological informa- tion was obtained, only a small portion of which is included in the following list. All records of species from elm in this paper are based on observations made during the course of the work.

In a project of this sort involving a large number of different groups of insects, the cooperation of specialists in the various groups is of primary importance. Without exception this coopera- tion was willingly given. Special acknowledgment is due Mr. C. F. W. Muesebeck and Mr. Henry Townes who determined the Ichneu- monoidea, and to Mr. A. B. Gahan who determined the Chalci- doidea, to Dr. W. T. M. Forbes who determined the Lepidoptera, and to Dr. C. H. Curran who determined most of the Diptera. Acknowledgment to the many other specialists who identified specimens is given throughout the list.

Most of the laboratory work involved was done at the Boyce Thompson Institute for Plant Research at Yonkers, N. Y., and all cooperation received from that institution is greatly appreciated.

York State in ‘‘A List of the Insects of New York” (Leonard, Cornell Mem. loi, 1928) are indicated by an asterisk (*).


(All Coleoptera determined by Mr. Henry Dietrich unless other- wise noted.)



Members of this subfamily are frequently encountered under the moist decaying bark of dead elms.


Conosoma opicus (Say). This species is fairly common under moist bark.

Conosoma crassus (Grav.). This species is found in the same situations as C. opicus, but is usually less common.



Platysoma depressum Lee. Found under moist bark.

Platysoma coarctatum Lee. A very common species under elm bark where it is usually associated with Saperda tridentata or various Scolytids. Usually it is found in the well-developed larval galleries of wood-boring insects, but it has occasionally been noted in the fresh maternal tunnels of entering Hylurgopinus rufipes.

Paromalus aequalis Say. Under the moist bark of dead elms.

Isomalus bistriatus Er. Under the moist bark of dead elms.



Attains sp. One specimen from a small dry branch of a dying elm.



Enoclerus nigripes Say. A common predator of Hylurgopinus rufipes. The adults frequent elm logs where they prey on entering or emerging H. rufipes, and the larvae feed on the larvae and pupae of that species. The life cycle corresponds to that of H. rufipes, and it is doubtless of great importance in keeping that species in check.

Hydnocera unifasciata Say. Much less common than E. nigripes, but of similar habits.

10 Bulletin of the Brooklyn Entomological Society Vol. XXXII


Dendroides bicolor Newn. The larvae of this species are quite abundant under the moist bark of dead and decaying elms. The adult beetles, however, oviposit in freshly cut wood.



Alans oculatus (L.). The larvae of this beetle are occasionally found in decaying elm logs. It is probably predacious on associated insects. The larvae of Alohates pennsylvanica and Synchroa punc- tata are frequentty found with it.


Dicerca divaricata (Say) . One specimen was reared from a dead elm branch.

Anthaxia viridicornis (Say). A rather common borer in the smaller branches of elm. In most cases this species was in associa- tion with A. viridifrons Gory. These two so-called species were on several occasions found mating and, therefore, all records are grouped under Say’s species.

Chrysobothris femorata (Oliv.). The larvae of this species were fairly common in freshly cut elm logs in several localities.


Tenebroides bimaculatus (Melsh.). Occasionally found under bark.

Tenebroides corticalis (Melsh.). Common under elm bark, both freshly cut and well decayed. Both adults and larvae are probably predators of wood-boring insects.


Silvanus bidentatus (Fab.). A few specimens under the moist bark of a dead elm.

Silvanus imbellis Lee. Under bark of an elm log.

Cucujus clavipes Fab. Adults and larvae of this species are fre- quently quite abundant under the bark of dead and dying elms.

Laemophloeus fasciatus Melsh. Found in small numbers under elm bark.

Laemophloeus liquidus Csy. Very common under decaying elm bark. It is occasionally found in the tunnels of bark beetles in recently killed wood.

Fe~b.,i937 Bulletin of the Brooklyn Entomological Society 11


Synchita fuliginosa Melsh. One specimen reared from an elm log. Yonkers, N. Y., July 30, 1935.

Eucicones marginalis (Melsh.). One specimen reared from an elm log. Pelham Bay Park, N. Y. City, June 30, 1936.

Bothrideres geminatus (Say). One specimen under elm bark. Tarrytown, N. Y., August 8, 1936.



Diaperis maculata Oliv. Adults of this species were found under the bark of a dead elm at Ithaca, N. Y.


Alohates pennsylvanica (DeG.). Adults are frequently found under the bark of dead elms; the larvae are found in similar situa- tions and in well-decayed wood.


Strongylium tenuicolle Say. One specimen was reared from an elm log. Yonkers, N. Y., July 20, 1935.


Synchroa punctata.. Newn. Common in dead elm in which the bark is still in close contact with the wood. The adults usually oviposit in the living wood of dying trees or in freshly cut wood, but the wood is invariably well decayed by the time the larvae are full grown. The larvae are apparently scavengers.



Ptilinus ruficornis Say. Reared in considerable numbers from a dead branch of a living elm.



Parandra hrunnea (Eab.). The larvae of this species are occa- sionally found in elm.


Physocnemum hrevilineum (Say). Occasionally reared from elm logs collected in various localities.

Xylotrechus colonus (Fab.). Fairly common in weakened elms..

12 Bulletin of the Brooklyn Entomological Society Vol. XXXII

The tunnels are largely in the bark, scarcely scoring the wood. All emergence took place in early June.

Neoclytus acuminatus (Fab.). A common insect in weakened trees and freshly cut elm wood. It sometimes bores between the bark and wood, but more frequently its tunnels penetrate deeply into the wood.

Anthoboscus ruricola (Oliv.). Observed ovipositing on elm logs in May at Patterson, N. Y. (C. H. Martin.)


Psapharochrus quadrigibhus (Say). Observed ovipositing on elm logs at Patterson, N. Y. (C. H. Martin.)

Astylopsis macvda (Say). A few specimens were reared from elm logs.

Leiopus variegatus (Hald.). A few specimens were reared from elm in May and June, 1935.

Graphisurus fasciata (DeG.). One specimen reared from an elm log. Tarrytown, N. Y., Sept. 16, 1936.

Saperda tridentafa Oliv. One of the most abundant of all elm insects. Although the adults are not commonly met with in the field, all dying trees examined contained large numbers of Y. tri- dentata larvae. Some members of a single brood of this species complete their life cycle in one year while other members of the same brood take two and possibly three years to complete their development. Many parasites were reared in association with S. tridentata.

Oberea tripunctata (Swed.). Larvae of this species were found boring on two occasions in the small twigs of elm, causing the tip to break over and the leaves to wither.



Magdalis pandura Say. Emerged in small numbers from elm wood collected at Crugers, N. Y. Emergence took place during the last week in May.

Magdalis barbita Say. Rather common in smaller elm branches, but is occasionally found in the larger branches or even in the trunk. It is frequently found in association with M. armicollis.

Magdalis armicollis Say. This species is more common than M. barbita and sometimes does considerable damage to elms. Most of the emergence takes place in June, but occasional specimens are found throughout the summer. The males of this species are fre- quently completely black and difficult to distinguish from M. barbita.

Feb., 1937 Bulletin of the Brooklyn Entomological Society 13

Conotrachelus anaglypticus (Say). Occasionally found on the foliage and branches of elm. The larvae mine in the cambium around the edges of wounds.

Cryptorhynchus obtentus (Hbst.). A few specimens of this species were reared from elm branches.


Acamptus rigidus Lee. One specimen of this strange Cossonid emerged on June 5, 1936, from elm wood collected at Crown Point,

N. Y.

Cossonus impressifrons Boh. Under the bark of a dead elm at Yonkers. N. Y.

Pentarthrimis parvicollis Csy. This species was quite numerous in a dead elm stub collected at Tuckahoe, N. Y., September 2, 1936.

Stenoscelis brevis (Boh.). This species is quite common in dead elms through which it tunnels in all directions.



^ Scolytiis multistriatus (Marsh.). This imported species is abundant in the New York City area and for a considerable dis- tance up the Hudson River Valley. Its habit of feeding in the twig crotches of healthy elms makes it of primary importance in the dis- semination of the Dutch Elm Disease organism. It prefers to breed in weakened or recently cut elms.

Scolytus sulcatus Lee. This species was formerly thought to be very rare, but it has been reared from elm in many localities in New York State. It is, however, not a common insect. Like S', multi- striatus it also feeds in twig crotches, and is, therefore, of potential importance in the spread of the Dutch Elm Disease organism.


Hylurgopinus ru pipes (Eich.). This species is quite common in New York State wherever elms are found. It prefers to breed in dead trees, the dead and dying portions of living trees, and in felled wood that has been cut some time.


Monarthrum mali (Eitch). This species was found entering elm logs in large numbers at Patterson, N. Y., on May 8, 1936. (C.

H. Martin.)

Xyloterinus politus (Say) . Found boring in elm at Varna, N. Y., on September 29, 1936. (H. Dietrich.)

14 Bulletin of the Brooklyn Entomological Society Vol. XXXII

Anisandrus minor Sw. This species is quite common in elm logs. It seems to prefer rather freshly cut wood.



Xiphydria sp. This species, which is probably X. tibialis Say, was reared in moderate numbers from elm collected in various parts of New York State. The larvae bore through the solid wood of dead and dying trees.

Xiphydria hicoriae Roh. (Det. D. Ries.) This borer was fairly common in elm collected at Haverstraw and Nyack, N. Y. Its habits in boring are similar to the preceding species. Emergence took place during the last of July and the first of August.



Tremex columba L. This species has been reared from elm and has been observed on several occasions ovipositing in large numbers on dying elms.



Sawfly larvae of this subfamily were collected about one centi- meter beneath the surface of a dead elm branch. Dr. H. H. Ross in correspondence states that the larvae of this subfamily feed on herbaceous plants and when full grown bore into twigs, bark, apples, etc.

Strongylogastroidea unicincta (Nort.). (Det. W. Middlekaufl:*.) One specimen from an elm log.


Strongylogaster politus Cress. (Det. W. Middlekaufl.) Two specimens were reared from elm wood. May 3 and 5, 1936. This species feeds on the fern Pteris aquilina, but it has also been reared from the pith of elder and sumach.



Coenocoelius saperdae (Ashm.). (Det. Townes.) This species is a very common parasite of Saperda tridentata and was reared in large numbers. It emerged throughout the season but was most common in June and July. Mr. Townes states that the specimen of Coenocoelius rugosus Prov. recorded as a parasite of X. tridentata

Feb., 1937 Bulletin of the Brooklyn Entomological Society 15

in the list of New York insects (Leonard, 1928) is also C. saperdae.

Coenocoelius erythrogaster (Roh). (Det. Muesebeck as Capi- tonius erythrogastra.) One specimen of this insect was reared from elm. Yonkers. N. Y., June 23, 1936.


^ At any coins idmicola Vier. (Det. Muesebeck.) This insect is also a common parasite of 5'. tridentata although less common than C. saperdae. It appeared in numbers in the spring and fall, but is only rarely seen in midsummer.


Spathius canadensis Ashm. (Det. Muesebeck.) This species was the most abundant of all parasites reared from elm. It was reared as a parasite of Hylurgopinus rufipes, Magdalis harbita, and Magdalis armicollis. It probably also attacks Scolytus multistriatus and possibly Saperda tridentata.

Spathius sp. One specimen from elm, Yonkers, N. Y., May 29, 1935-


* Heterospilus n. sp. (Det. Muesebeck.) The larvae of this species are external parasites of Saperda tridentata. The adults appeared in fair numbers during the last of August and the first of September.


Triaspis curculionis (Fitch). (Det. Muesebeck.) One speci- men of this insect was reared from elm wood.

Chelonus sp. A few specimens were reared from elm.


Apanteles sp. i. One specimen from elm.

Apanteles sp. 2. One specimen from elm. Both this and the preceding were probably parasitic on a Lepidopterous bark feeder.


Euhazidon magdali (Cress.). (Det. Muesebeck.) A common parasite of Magdalis harbita and M. armicollis. Its emergence like that of its hosts is in the spring, but occasional specimens are found throughout the summer and fall.

Eubadizon sp. (Det. Muesebeck.) Occasional specimens were reared from elm at various times.

16 Bulletin of the Brooklyn Entomological Society Vol. XXXII


Helconidea albitarsis (Cress.). (Det. Townes.) Several speci- mens of this parasite emerged from elm wood in May.


* Synaldis sp. (Det. Muesebeck.) One specimen from elm.



* Chaeretymma sp. (Det. F. D. DeGant.) One specimen reared from elm wood on May 20, 1936. Mr. DeGant states that this may be the male of C. kennedyi DeGant MS.

* Chaeretymma n. sp. One specimen of this new species, which is to be described by Mr. DeGant, was reared from elm wood on May 27, 1936.

* Chaeretymma singara DeGant MS. (Det. F. D. DeGant.) One specimen of this species was foound dead in the larval tunnel of Dicerca divaricata in elm at Mt. Ivy, New York. Another speci- men of Chaeretymma was found with C. singara, but was so mutilated that identification was impossible.


Asphragis sp. (Det. R. A. Cushman.)

this insect was found beneath the bark of a dead elm at Yonkers, N. Y., on September ii, 1936.



Reficulitermes flavipes Kollar, The bases of dead and dying elms were occasionally found to be infested with this insect.


(Determined by Dr. P. J. Chapman.)

Corrodentia are frequently found in elm bark especially that of dying or dead trees. They probably feed on the fungi' which grow under such conditions.
