of North America, .separated Say's genus Toxoneuron from other 

 Braconids as a distinct subfamily under the name of Toxoneurinm, the 

 distinguished divine evidently being unaware at that time of the 

 identity of that genus with Cardiochiles Nees. 



The group is a good one, intermediate between the AgathidincB and 

 the Mio'ogasterincB, and readily distinguished by the venational charac- 

 tei's employed in my table of subfamilies. 



The following are the essential characters for its recognition: 



Front wings with three cubital cells, the marginal cell elongate, the third abscissa of the 

 radius reclivate, the second cubital cell longer than wide; hind wings with two 

 marginal cells; mesonotum with distinct furrows converging and meeting pos- 

 teriorly; metathoraxareolated, the areola lozengoidal, rarely indistinct; antennae 

 16-iointed ( ^^^^ ) Cardiochiles Nees.

This is a large and most difficult group, its nearest allies being the 

 AqatMdhux. and the CavdlocMUnoi. 



The absence of parapsidal furrows and the rather full characters 

 employed in my table of subfamilies will, however, render the group 

 easily recognized. 



The group is probably susceptible of tril)al divisions. Neoneurm 

 «nd Elmmosoma will fall together; then Mhax and allies; and finally 

 the genuine Microgasterines, Apantdcs, Microgader, etc. 



Flumarius Philippi, descri})ed from South America, is unknown to 

 me in nature, but evidently, judging from the figure and description,! > 

 belongs to this group. Cot&^ia Cameron, is also unknown to me; if j 

 may yet prove to be identical with Apantdes Forster. I , 



The genera at present recognized may be distinguished by the char 

 acters made use of in the following table:
