This species is quite distinct from the two described by Brulle 

 in tiie ' Histoire Naturelle des Insectes,' and from that described 

 by G-uerin in the ' Voyage de la Coquille ' under the name of 

 Bracon sjyinator -. our species most closely resembles the latter, but 

 differs in having the wings entirely dark, in having the abdomen 

 deeply striated, and in not having a spine in the middle of the 

 margins of the third and fourth segments of the abdomen.
