Coleoptera. Dr. Calvert also exhibited a female and two males of 

 Calopteron reticulatiim Fab., which latter were apparently attempting to 

 pair simultaneously with the former, all pinned in approximately the posi- 

 tions in which they were found, the female with the four wings outspread, 

 one male above, the other male on the right side of, her abdomen. The 

 speaker had taken them near Cheyney, Pennsylvania, July 16, 1919.

Meeting of November 20, 1919. Fourteen persons present, including 

 Mr. Allie M. Ross, visitor. Mr. R. C.Williams, Jr., Vice-Director, 

 presiding. 



Mr. Williams spoke of meeting C. J. Huguenin and C. L. Fox, while in 

 California. The visitor, Mr. Ross, spoke about his intended work in Liberia, 

 especially his desires of working up the fauna of that region in the Lepid- 

 optera and Orthoptera. 



Orthoptera. A series of Mantidae from the Sundanand Papuan regions 

 were exhibited by Mr. Hebard. It was pointed out that many of the 

 genera were new to Philadelphia collections and that some of the species 

 had remained unknown to subsequent authors since their original descrip- 

 tion. Certain striking forms were discussed, and the difficulties experi- 

 enced in studying the Orthoptera of the regions in question were pointed 

 out. In determining large series from the regions under consideration, 

 Mr. Hebard said that he had found such studies as Haan's "Bijdragen tot 

 de Kennis der Orthoptera," published in 1842, of the utmost value, but 

 that many contemporary authors were producing a far inferior literature, 

 describing species with deplorable brevity and often giving no figures what- 

 ever. 



Mr. Rehn exhibited a box containing a series of the West Indian forms 

 of the genus Eurycotis of the family Blattidae. The speaker discussed the 

 genus, its distribution, general morphological tendencies in the way of 

 specific differentiation, color types developed in the genus, and the groups 

 into which he had arranged the West Indian forms. Of the West Indian 

 forms exhibited the majority were either recently described or are as yet 

 undescribed. 



Lepidoptera. Mr. Reyher exhibited type specimens of Catocala sapho 

 var. cleis. (Cassino) from Florida, and said that he could find no characters 

 by which to separate this variety from the type form.
