 of abdominal segments, yellow : antennae thickened beyond the middle ; wings 

 yellowish-fuscous, hyaline at tips.

 with fine punctures, interspersed with large deep punctures; anterior 

 margin of the clypeus cariuated and somewhat recurved ; labvum and 

 mandibles clothed with pale setae, the latter rufo-piceous about the 

 middle; palpi testaceous ; antenna? about as long as the head and tho-

 margin deeply emarginate, so that the lateral angles are prominent and 

 spiniform, but not acute, at base there is a deep transverse excavation 

 which is striated and black, the sharp carina on each side is yellow and 

 continues to the tip of the scutellum, which has also a well impressed 

 line down the middle; postscutellum and metathorax black, the latter 

 is rugose, with a smooth polished space on each side at base enclosed 

 by a well defined carina, on each side, just above the middle coxae, a 

 large rounded yellow spot, as well as a dot above it; tegulae black. 

 Wings ample, yellowish-fuscous, with a slight brassy gloss, the apex 

 beyond the areolet hyaline ; nervures fuscous, the costa and stigma
