PROCEEDINGS OF SOCIETIES. 



CAMBRIDGE ENTOMOLOGICAL CLUB. 



10 April 1891. — The i62d meeting of the 

 club was held at 1^6 Brattle Street. Mr. J- 

 H. Emerton was elected chairman. 



Mr. S. H. Scudder exhibited a series of 

 over thirty specimens of the acridian Bryo- 

 dema tuberculata collected many years ago 

 bv Parschine in the Trans-Baikal and Amur 

 regions of eastern Siberia, namely at Irkutsk, 

 Verschine-Udinsk, the desert of Khorinskaya 

 in southern Siberia, Khabarowka, and Sara" 

 pol. They showed an extraordinary amount 

 of variation in the intensity and extent of the 

 band crossing the hind wings as well as in 

 the depth of the basal tint, some being 

 almost or quite vitreous, while others at the 

 other extreme were a deep rose ; the apex of 

 the wing in some was entirely infumated so 

 as to connect completely with the transverse 

 band, while others showed a broad vitreous 

 space outside the transverse band, darkened 

 by the veins only ; similarly a great variation 

 was seen in the depth and extent of the mot- 

 tling of the tegmina and no little difference 

 in the surface sculpture of the dorsum of the 

 pronotum and the vertex of the head. In all. 

 the anterior sulcus of the prozona was far 

 less deeply impressed than in European spec- 

 imens of the same species. Mr. Scudder 

 also showed specimens of the allied B. bara- 

 bensis collected by Parschine at Verkhni- 

 Udinsk, Verschine-Udinsk, Strelinsk, and 

 the desert of Khorinskaya. 



Mr. J. H. Emerton remarked on the New- 

 England species of Attidae. He stated that 

 thirty-three species of this family are repre- 

 sented in his collection, of which eight are 

 undescribed. Of these, eight belong to 

 Phidippus and Dendryphantes, seven to the 

 short bodied genera allied to Attus pulex and 

 A. falustris of Hentz, and three to the ant- 

 like genera. The classification of the re- 

 maining species is still undecided. Four 

 species are represented by only one, and 

 three others by only two or three specimens 

 each. Mr. Emerton showed a number of 



drawings illustrating the variations in this 

 family. 



Mr. R. Hayward recorded the capture in 

 Arizona by Mr. H. K. Burrison of Af/iodius 

 pu in Hits, a species described by Dr. Horn in 

 his recent Revision of Aphodius from New 

 Mexico, but which has also been taken by 

 Mr. Bowditch and Mr. Hayward in northern 

 New Mexico. 



8 May, 1S91. — The 163d meeting of the 

 Club was held at 156 Brattle Street. Mr. J. 

 H. Emerton was chosen chairman. After 

 the additions to the library had been an- 

 nounced the Club proceeded to the election 

 of officers for 1891 which had been post- 

 poned. The following were elected : Presi- 

 dent, Prof. F. II. Snow, of Lawrence, Ks. ; 

 Secretary, Roland Hayward; Treasurer, 

 Samuel Henshaw; Librarian, Samuel H. 

 Scudder ; members at large of Executive Com- 

 mittee, J. H. Emerton and T. W. Higginson. 



Rev. W. J. Holland and Mr. A. P. Morse 

 were elected to active membership. Mr. S. 

 H. Scudder communicated some notes on 

 Oeneis (see Psyche, v. 6, p. 99-100). Mr. J. 

 H. Emerton remarked briefly on certain crab- 

 spiders (Thomisidae) comparing them with 

 the Attidae, an allied family. 



12 June, 1891. — The 164th meeting was 

 held at 156 Brattle Street. Mr. J. H. Emer- 

 ton in the chair. Mr. S. Henshaw was 

 chosen Secretary fro tern. Mr. F. C. Bow- 

 ditch was elected a member. 



Mr. J. H. Emerton showed some plates of 

 New England Attidae, and remarked upon 

 the character and distribution of a number 

 of the species; 16 or 17 genera and about 55 

 species are known from New England. 



Mr. S. H. Scudder showed drawings by 

 Mrs. Peart of the terminal segments of the 

 young larvae of Oeneis brucei, Oe. jutfa, and 

 Oe. macounii, and said that his proposed di- 

 vision of the genus, as given at the last 

 meeting, into two groups for which the sub- 

 generic names of Oeneis and Chionobas 

 were suggested, appeared to be well founded. 

 Mr. Scudder also showed the early stages of 

 several European butterflies.
