210 PSYCHE. [January 1892.
PROCEEDINGS OF SOCIETIES.
CAMBRIDGE ENTOMOLOGICAL CLUB.
10 April 1891. -The 162d meeting of the
club was held at 156 Brattle Street.
Mr. J.
H. Emerton vfsis elected chairman.
Mr. S. H. Scudder exhibited a series of
over thirty specimens of the acridian Bryo- dema tuberculata collected many years ago by 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 Attusfulex 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. Bun-ison of Aphodius fumHus, 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, 1891.-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. H. 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 -pro fern. 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 33 species are known from New England.
Mr. S. H. Scudder showed drawings by
Mrs. Peart of the terminal segments of the young larvae of Oeaeis brucei, Oe.jutta, 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.
