some synonyms are still retained as valid species in some catalogues 

 and lists. Mr. David E. Harrower was elected an associate. 



Orthoptera. Mr. H chard made a communication on four species 

 of the genus Periplancta. All were stated to be native in the I'nited 

 States, though hut three from this country have been recognized in 

 the fiterature. Certain features of coloration were shown to be of 

 diagnostic importance, but recession and intensification of the color 

 pattern was stated to be sometimes sufficient to lead to confusion in 

 determining individuals of some of the species. The male primary 

 and secondary sexual features were said to be of the greatest diag- 

 nostic value, rarely showing even slight individual variation, and dif- 

 fering widely in each of the species exhibited The remarkable de- 

 velopment of the male concealed genitalia was discussed for each 

 species. In the discussion which followed comments were made on 

 the views of some of the early students on the systematic value of 

 the genitalic characters, most authors not recognizing such especially 

 where there was any asymmetry. Mr. Rehn spoke of the importance 

 of the genitalic characters in the separation of species and genera. 



Lepidoptera. Dr. Skinner read a communication from Mr. 

 Howard J. Shannon, 73 Union Ave., Jamaica, New York, asking that 

 records be made of the captures of Anosia plexippus along the At- 

 lantic coast. He has liberated 1000 specimens which were marked 

 with a design cut in one of the hind wings, and will gratefully ac- 

 knowledge receipt of such records. Mr. Laurent spoke about the 

 attraction of butterflies to the butterfly-weed and exhibited specimens 

 of the following species which were captured on the flowers of the 

 plant during the first five days of this month : Danais plexippus Fab., 

 Argynnis cybele Fab., Phyciodes tharos Dru., I'ancssa antiopa Linn., 

 Pyramcis huntcra Fab., Lime nit is Ursula Fab., Lycacna cotnyntas 

 Godt., Picris rapac Linn., Colias philodice Godt., Papilio glaucus Linn, 

 and var. turnits L-, P. philenor Linn., P. troilus Linn., P. polyxenesHfab., 

 Pomphila hobomok Harris, P. pcckius Kirby, P. cerncs Bd. & Lee. 

 and Eudamus tityrus Fab. He called attention to the species I'ancssa 

 antiopa and Limenitis ursula which, he stated, seldom come to flower. 

 Other species also were observed on this plant. 



Diptera. Dr. Skinner spoke of a case of a white rabbit from 

 a nearby suburb, infested with the larvae of a bot-fly. He commented 

 on the apparent scarcity of adults of these flies about Philadelphia 

 although many rabbits are found to be infested. E. T. CRESSON, JR.
