Antonna^ inserted on a frontal prominence; in 9 12-jointe(l, elavate 

 or strongly incrassated toward tips, the scape reaching beyond the 

 ocelli, thickened ai)ically; pedicel rounded; in (5 14-jointed, long, tlli- 

 tbrni ; the scape cylindrical. 



Maxillary palpi o-jointed. 



Mandibles short, bidentate. 



Thorax oblong; prothorax visible from above, the angles rounded; 

 mesouotum with two distinct furrows; scutellum subconvex, bifoveated 

 at base; metatliorax short, subemarginated, the i)osterior lateral angles 

 acute. 



Front wings with the submarginal vein terminating in a stigma, be- 

 fore attaining the costa, and from wliich issues a short stigmal vein 

 knobbed at tip; basal vein absent. 



Hind wings veinless. 



Abdomen long, oval, S-jointed, the [»etiole strigose, hairy. 



Legs moderate, the femora elavate, the tibia' subelavate, pilose; basal 

 joint of posterior tarsi three or four times as long as the second; claws 

 small, simple. 



This genus comes nearest to L<(holip.s, but is readily distinguished 

 by the maxillary palpi and the knobbed stigmal vein. 



Abbe Provancher described three species under this genus, none of 

 which belong here. AneiirhyiichuN (menrKs Yrov. is a ^ Platygasterid 

 belonging to the genus Lsocyhxs, while .1. sphiosiis and A. inermis Prov. 

 are Belytids. 



I have recognized three species in our favina, which may be tabula- 

 ted as follows:
