THE ENTOMOLOGICAL SOCIETY OF WASHINGTON. 



September 4, 1890. — Under the head "short communications and exhibition of 

 specimens," Mr. Heidemann spoke of the occurrence of CyJapuH tentiicornis (Capsidje) 

 near Washington, D. C, and Mr. Schwarz exhibited specimens of Choragus nitens 

 (Anthribid;e) lately found in the District, also a branch of Carpinus infested in a 

 peculiar way by the larvte of Acoptm suturalis (Curcuiionidse), and a specimen of 

 Bymenarciis nervosa with deformed anteunie, and he also called attention to the 

 reported discovery of the stylopized Gryllotalpas in eastern Africa. Dr. Marx 

 reported having found specimens of Latrodectus under a board, devouring carabids — 

 the webs of the spider being garnished with fragments of the beetles. As possibly 

 throwing light on the subject, Professor Riley mentioned having been greatly sur- 

 prised this summer at the large number of insects, Lachiiosterna, Xylocopa. Bombus, etc., 

 that he found about his grounds at Sunbury, Avith large perforations and apparently 

 killed by birds, and probably the house wren. Mr. Fox thought that spiders were 

 largely responsible for this work. Professor Riley described his recent investigations 

 into the life-history and habits of Sphecius speciosus, exhibiting specimens of the egg 

 in situ on Cicadas, and of the young and full-grown larvte and cocoons. Careful 

 drawings were shown illustrating the different stages and habits of Sj^hecius. 



Mr. Schwarz queried, in view of the earlier appearance of the C. septendecim, 

 whether Sphecins ever preyed on that species. Professor Riley showed that the 

 period of septendecim and Sphecius overlapped, and that the general belief that Sphecius 

 attacked the seventeen-year locust, while not based, so far as he recalled, on obser- 

 vation, was probably well founded. 



Mr. Howard exhibited 8i)ecimens of sand cricket, Stenopelmatus fasciatus, which 

 had been recently sent to Professor Riley by one of his correspondents. Mr. Howard 

 stated that they occurred abundantly in the Southwest, and are reported errone- 

 ously to be extremely poisonous. As stated by Professor RTiley in the Standard 

 Natural History, they are carnivorous in habit. 



Mr. Mann described some observations and experiments relating to the longevity 

 of decapitated specimens of Caloptenus and the vigorous resistance of such speci- 

 mens to the attacks of ants. 



Mr. Schwarz, "On Black Locust Insects," presented a list of twenty-four species 

 of Coleoptera bred by bim in May from dying trunks of Black Locust, and spoke of 

 the principal insect enemies of this tree in the District. Discussed by Messrs. 

 Riley and Howard. 



Mr. Schwarz also read a paper on the food habits of some Scolytidse observed by 

 him during the summer. Galleries of the following species were exhibited and ex- 

 plained : Xyloterus politus in Acer das'^-carjmm ; Xyleborus Jurcatus aud puiercus in 

 Walnut; Cnesinus strigicoUis in Liquidamhar styracijlua.
