era! way shows eveiy thing except the legs ; but the basal parts of the wings 

 are obscured on account ol" their overlying the body, and give the remainder 

 a foreshortened look. The antennte are tolerably stout, a portion longer than 

 the large thorax being preserved, with joints a little more than twice as long 

 again as broad. The thorax is large, massive, arched, twice as high as the 

 head, regularly ovate, and half as long again as high. The wings are toler- 

 ably broad, and the neuration is obscured by the overlying of the wings 

 and the crumpling of some of them ; it shows, however, a long first cubital 

 cell separated from the second by a mimite triangular areola attached bv 

 its apex directl}' to the radius, with no intervening pedicel, and containing 

 a brief, outward directed, recurrent nervule emitted from the cubital vein 

 slightly nearer the areola than the outer discoidal cell. The abdomen is 

 very obscure, but is certainly very short — no longer than head and abdo- 

 men together — and appears not to be broadest apically, but only a little 

 beyond the middle ; but this can not be stated positively. The ovipositor 

 is considerably longer than the body, stout and straight ; it is densel}" 

 clothed with fine, shox't, recumbent hairs to its very tip.

Tliis species is represented' by a single specimen presenting a shattered 

 thorax, the first four abdominal segments viewed from above, and the front 

 wing. These abdominal segments are pretty uniform and regular, rather 

 strongly convex, pale testaceous, with a broad, blackish fuscous, basal, 

 transverse band, occupying fully one-third of each segment; the segments 

 are quadrate, broader than long, and smootli. Tlie metathorax is pale tes- 

 taceous, and very delicately scabrous. The wing is uniformly hyaline, or 

 shows the slightest trace of infumation, esj>ecially at the extreme tip, and is 

 uniformly and rather sparsely covered with microscojiic hairs, averaging
