previously undescribed. The larva nearly resembles that of A. 

 hamamelis (inclara Sm.) ; indeed from the mature larva alone 

 no constant differences can be pointed out, but Dr. Dyar has 

 observed certain differences in the earlier stages of these larvae 

 which will be more fully worked out at the next opportunity. 

 In this connection he also presented a list of Apatela by Prof. 

 A. R. Grote, with generic and subgeneric types, which had been 

 prepared by Professor Grote on request, and which is supple 

 mental to the monograph of the genus recently published by 

 Smith and Dyar. Dr. Dyar stated that he was pleased with 

 Professor G rote's erection of a subgenus for A. funeralis, since 

 this was definable on larval characters, as are all the other 

 subgenera of Apatela, except Tricholonche as compared with 

 Lepitoreuma. 



LIST OF NORTH AMERICAN APATELA. 

 By A. RADCLIFFE GROTE, A. M. 



In this list I have arranged the species following Dr. Dyar's 

 recent groupings of the larva, except that I retain the subgeneric 

 names Tricholonche and Lepitoreuma as distinct. The latter 

 was described by me in 1873 with the type ovata ; founded upon 

 the shape of the primaries, the contents of this group have been 

 always homogeneous in my writings and the type and title must be 

 retained. The neuration of the type of Apatela does not differ 

 essentially from that of the type of Agrotis. Species of which 

 the larvas are known are marked with an asterisk (*).
