Antenna' inserted on sv frontal prominence; in 9 12-jointe(l, clavate 

 or strongly incrassated toward tips, the scape reaciliing beyond the 

 ocelli, thickened apically; pedicel rounded: in <? 14-joiu4;ed, h)ng, tili- 

 forni ; the scape cylindrical. 



Maxillary palpi .-) jointed. 



Mandibles short, bidentate. 



Thorax oblong; prothorax vi.sible from above, the angles ronnded; 

 niesonotuni with two distinct fnrrows; scntellnm snbconvex, bifoveated 

 at base; metathorax short, snbemarginated, the i)osterior lateral angles 

 acnte. 



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

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

 knobbed at tip; basal vein absent. 



Hind wings veinless. 



Abdomen long, oval, 8-jointed, the petiole strigose, hasiry. 



Legs moderate, the femora clavate, the tibia' siibclavate, pih>se; basal 

 joint of ])osterior tarsi three or four times as long as the second; daws 

 small, simide. 



This genus comes nearest to Laholipn, but is readily distinguished 

 by the maxillary i^alpi and the knobbed stigmal vein. 



Abbe Provancher described three species under this genus, none of 

 which belong here. AnenrhijnchuH aneuruH Prov. is a $ Platygasterid 

 belonging to the genus laocybns, while A. sjnnosus and A. inerniis Prov. 

 are Belytids. 



I have rec(ignized three species in our fauna, which may be tabula- 

 ted as follows:

Frontal iicl<je pale iiifous.

2 . Length, 2.5""". Polished black, sparsely pubescent. AntennsB 

 12-jointed, stout, clavate, rufous; the scape is very thick, a little 

 shorter than half the length of the Hagellum; pedicel stouter, but not 

 as long as the first flagellar joint; second flagellar joint shorter than 

 the first; third, shorter than the second; from thence the joints are 

 transverse, increase in size and width, and are well separated. Mesono- 

 tal furrows distinct. Scutellum with two transverse fovete almost
