Antenna' in $ subsetaceous, 12-joiDte(l, the flagellar joints all long 

 cylindrical. 



Maxillary palpi long, 5-jointed; labial palpi 3-jointed. 



Mandibles arcuate, .^-dentate, the outer tooth large, the inner two 

 teeth small, equal. 



Thorax ovoid, the prothorax abruptly truncate before, dilated at 

 sides ; mesonotum a little wider than long, with two deep distinct fur- 

 rows ; scutellum large, rounded behind ; uietathorax rounded behind, 

 the angles prominent. 



Front wings as in Sparasion. 



Abdomen fusiform, depressed, sessile, the sutures of the segments 

 deep, the segments themselves nearly equal in length. 



Legs much as in Spamnion, the tibial spurs being 1, 2, 2, but the hind 

 femora are much more swollen. 



This genus agrees more closely with Sparasion than any other genus, 

 and like that it is very hairy; but the absence of the frontal ledge, the 

 more distinctly pilose eyes, longer antenme, and the swollen posterior 

 femora separate it at once.
