the first recurrent nervure; hind wings always with two discal cells and 
with complete lanceolate cell. 
The following table of genera is based in part on the classification 
given by F. W. Konow,! and it is hoped that it will facilitate the recog- 
nition of the new genera, most of which are represented among our 
North American species. 
The revision of genera with redesecriptions of old species is limited 
to the genera formerly included in the genus Nematus. 
Of the other genera a list of the American species only is given, 
together with a few notes on synonymy.

2 Anoplonyx gen. nov. (av, without; Ozlov, weapon; Ovvé, claw) is separated from 
Camponiscus Newm. (of which Leptopus Hartig is a synonym) by the very important 
character of a simple claw without branch or inner tooth. The type of both New- 
man’s and Hartig’s genus is Camponiscus luridiventris Fall., in which the claws are 
deeply notched, the rays being subequal. Anoplonyx will include Camponiscus pec- 
toralis Lep., C. bicolor Lep.,and C. ovatus Zadd. The other two species of this genus, 
C. auritw Z. & B., and C. carinthiacus Z. & B., I have not had an opportunity to 
examine; they may belong with C. luridiventris or possibly come in the new genus.
