rations of one species were represented. The heretofore called 

 Aphis mali\s, not that species, and the name should be applied 

 to the one now under observation. The characters of the larva 

 were described, the insect going through four moults prior to 

 maturity. The larvae have at first a 3-jointed antennae, which 

 are enforced by an additional joint at the third moult. Two 

 series, winged and wingless, are found in the mature insects, 

 the antennae of each series showing peculiarities. The young 

 of these two series show quite distinctive characteristics. 



Mr. P. Laurent showed 102 species of Lepidoptera collected 

 by him recently in the Wasatch Mountains, Utah, and Manitou, 

 Colorado. Referring to the Argynnids, he stated that each of 

 the several .species represented were peculiar to different canons 

 in these Mountains. Specimens of Papilio rutilus from the head 

 of Big Cottonwood Canon are much smaller than the typical 

 form. A specimen of Admetovis shown is probably new. 



Mr. H. W. Wenzel exhibited specimens of Holopardmesus 

 raffiisa?, Cai'toderc costii/ata, Corticaria serrata, Monotonce qjiad- 

 rifovcolata,Cryptophagus croccus, and Mycetaea hirta, all of which 

 had been captured in the cellar of his hoiise. 



Prof. Smith stated he had received from the author species 

 of Argyiinis ccerulescens Holland, described as a variety of A. 

 notocris, and he had found on dissection of the genitalia that 

 the so-called variety is an apparently distinct species. 



Dr. Skinner stated that he could find no specific differences 

 in the drawings of the genitalia of males of Colias philodice and 

 C. eurythemc, which had been made by Prof. Smith from a 

 series of both species. 



Prof. Smith stated that he had received the abdomens only of 

 these two insects without any indication of the species to which 

 they belonged, and in his opinion there were two distinct species 

 among them, although an intermediate series was found which 

 is .somewhat puzzling, but he believed the differences shown 

 by this series may be due to the different method by which 

 some of the specimens were prepared for microscopic exami- 

 nation. The subject was further discussed by Messrs, Smith 

 and Skinner. 



Mr. William Reinick and Mr. S. Harbeck were elected 

 members of the Social. William J. Fox, Secretary.
