130 Cameron, Hymenoptera Oricntalia. 



the striations are stout ; on the apex, bordering the 

 central black band, is an obscure yellow one. Scutellum 

 yellow, black at the apex; transversely striated. Post- 

 scutellum smooth, lemon-yellow, bifoveate at the base. 

 The base of the median segment deep black, shining, 

 broadly depressed in the middle ; at the base are two 

 transverse keels ; the segment has a rounded slope, and 

 is covered with shallow, clearly separated punctures ; the 

 apex almost impunctate and deep black ; the middle has 

 a deep and wide furrow, which does not extend into 

 the apex. Propleurae punctured ; the middle obliquely 

 depressed, black on the basal half, and smooth ; the 

 extreme apex black, and coarsely punctured ; the extreme 

 base of the mesopleurse black ; below the tubercles is an 

 oblique, blackish band, from which another, broader and 

 less oblique, runs to the bottom ; the tubercles are large, 

 longer than broad, depressed at the base and apex ; the 

 apical furrow is crenulated. The base and apex of the 

 metapleurae depressed and black ; below the spiracles is 

 an oblique keel. The mesosternum closely and strongly 

 punctured, with a wide, stoutly transversely striated 

 furrow down the middle. Legs yellow ; the femora with 

 a rufous tinge ; the hinder coxae darker in front ; the tarsi 

 (especially the hinder) infuscated. Wings fulvo-hyaline ; 

 the stigma dark rufous ; the nervures darker ; on the apex 

 of the radial and the second cubital cellule is a fuscous 

 cloud ; the recurrent nervure is interstitial. Abdomen 

 dark rufous ; the apices of the segments broadly yellow ; 

 the basal two segments are slightly and widely punctured; 

 the middle much more closely and strongly ; the apical 

 closely, but not so strongly, and thickly covered with 

 fuscous hair. 



The amount of the black and yellow colour varies, 

 as does also the size.
