$ . Riifo-testacea ; capite pedibusque nigria ; segmento dorsali 

 primo pallide flavo ; segmentis veutralibus albidis, lateribus 

 nigro-marginatis ; alia fuscis, venis nigris, stigmate fusco-

Long. 8 mm. ; terebra? long. 3 mm. 



? . Face finely punctured, sparsely clothed with long 

 cinereous hairs. Pronotum slightly concave, margined, 

 with a short carina from the hind margin to the middle, 

 a small acute tubercle on each side ; parapsidal furrows dis- 

 tinct. Postscutellum with three strong longitudinal carina? ; 

 median segment with two strong longitudinal carina? from 

 base to apex. First tergite about as broad at the apex as 

 long, coarsely longitudinally striated, the sides with a deep 

 broad longitudinal groove between carina?, two longitudinal 

 carina? from the base converging towards the apex, the apical 

 half of the segment with short irregular longitudinal stria? ; 

 second suture distinct ; second tergite with a broadly rounded 

 basal area, which is longitudinally striated at the base, punc- 

 tured at the apex. Sheath of the ovipositor black. Second

 scutellum, and postscutellum ferruginous, the pronotum 

 and pleura? black ; the median segment and three basal 

 abdominal segments brown, the apical segments black ; the 

 legs brown, variegated with black. The second abscissa of 

 the radius is more than twice as long as the second trans- 

 verse cubital nervure ; the spines of the pronotum are strong 

 and erect. Median segment punctured reticulate, with two 

 longitudinal carina? on the apical slope; first tergite almost
