Doings of Societies. 



ENTOMOLOGICAL SOCIETY OF WASHINGTON, Thursday, April 7, 1892. 

 Mr. George D. Bradford, of New York, was elected a corresponding 

 member of the Society. The discussion of Dr. Gill's paper entitled, 

 ' The Larva of Insects as an Intercalated Stage," engendered at the pre- 

 ceding meeting of the Society, was taken up and participated in by Messrs. 

 Stiles, Riley, Gill and Banks. Dr. Riley presented two papers, one "On 

 certain peculiar Structures of Lepidoptera," and the other, " Descriptions 

 of new Prodoxidce." He spoke of various interesting structures of the 

 Prodoxidae, calling attention more particularly to the saw-like ovipositors, 

 the maxillary tubercles, the cenchri-like spots on the thorax and certain 

 radiate and chitinous bodies in the receptaculum seminis. The remarks 

 were illustrated by large figures. He also spoke of the resemblance of 

 Pronuba synthetica to certain saw-flies. Specimens of the insects de- 

 scribed were exhibited. Prof. Riley's second paper was read by title only, 

 and was presented for publication. The discussion of these papers was 

 participated in by Messrs. Howard, Marlatt and Stiles. Prof. Riley also 

 presented a paper on "Coleopterous Larvae with Dorsal Appendages," 

 in which he described the larva of various species of Mordellistena hav- 

 ing rows of tubercles on the back which facilitate moving more readily in 

 the hollows of plants and the larger burrows of other insects. Discussed 

 by Messrs. Smith and Schwarz. Mr. Doran read a paper entitled "On 

 the Heat Produced by Sylvanus cassia," in which he recorded some ob- 

 servations which he had made on the amount of heat produced by these 

 beetles in meal, but offered no definite explanation of the phenomenon. 

 Discussed by Messrs. Marlatt, Riley, Austin and Schwarz. 



Thursday, May 4, 1892. Prof. H. E. Summers, of Champaign, 111., 

 was elected a corresponding member of the Society. Mr. Ashmead pre- 

 sented some notes on the genus Enicocephalus Westw. Biographical 

 and critical notes were given, and the announcement was made of the 

 discovery of representatives of this genus in material sent to Dr. Riley 

 from St. Vincent, and announced also the discovery of a new species in 

 Utali by Mr. Schwarz. The genus cannot be included in any of the pres-
