CORYMBICHNEUMON, g. n. 



This new genus diflfei^s from C<xlichneumon Thomson solely in 

 having the scutellum spherical ; it stands out from the thorax 

 in the form of a one-third embedded ball, and is not laterally 

 carinate. The only species yet known is remarkable for being 

 of sombre coloration, with botli the scutellum and mesonotum 

 conspicuously pale stramineous.
