Doings of Societies. 



Minutes of meetings of Brooklyn Entomological Society, 

 held at the residence of Mr. George Franck, 1040 DeKalb 

 Avenue, Brooklyn, N. Y. 



October 6, 1904.. — Fifteen persons present, the President in 

 the chair. 



The admission of the Society to the Scientific Alliance of 

 New York being reported, R. Ellsworth Call and Archibald C. 

 Weeks were elected delegates to the Council of that body. 



Dr. Carl Fulda, of Brooklyn, N. Y. was elected a member. 



The President called attention to the opportunity for original 

 research afforded by the rearing and identification of the larvae 

 of aquatic coleoptera. Heretofore, practically all the descrip- 

 tions related to mature forms, while the identity of the larvae 

 had been neglected, there being very little authentic literature 

 concerning them. The shed dytiscid larval and pupal skins 

 remained intact and so perfect that they could be easily pre- 

 served and accuratel}!' studied. An obstacle in rearing the 

 Dytiscidae would be found in supplying sufficient mosquito and 

 other larvae to satisfy their ravenous appetites. When their 

 natural food failed they developed cannibalistic traits, making 

 it advisable that each larva should be reared in a separate jar. 



Mr. Franck reported that a numerous swarm of Danais 

 archippiis had been recently seen near Rutherford, New Jersey 

 (one collector taking 700 specimens in two da3's), as proof of 

 the generally accepted theory that the assembling of this 

 species in the fall is preparatory for southward migration. 

 Discussion by Messrs. Franck, Watson and Weeks as to the 

 probability of northern hibernation of this butterfly. 



Mr. Wasmuth reported the capture of a larva of Callimorpha 

 dyari, at Jamaica, L. I., in the early spring, which fact, in 

 Prof. Smith's opinion, was sufficient evidence of its hibernation. 



Mr. Shoemaker exhibited a specimen of each of the follow- 

 ing moths : Cirropha^ius tria^ignlifer captured on September 

 2, 1904, in Alexandria Co., Va. , Graphiphora garmayiiXo^^wow. 

 April 27, 1904, at Brooklyn, N. Y., and Hepialus argenteoma- 

 cidata taken at electric light on May 30, 1904, at Washington, 

 D. C, and the carab Platyniis cordatum, of which he had ob-
