Indian species that have been described the male may be distinguished 

 by the sparse hairiness and narrowness of the cheek, and the relative 

 shortness of the posterior section of the second cubital cell. 



Male. — Front with primary punctures ranging from contiguous 

 above base of antennae to third-degree density in area lateral to 

 ocelli; numerous minute punctures on lower half extending on sides 

 into upper half. Antenna long and slender. Cheek (fig. 1a) much 

 narrower than diameter of an antennal fossa; sparsely hairy. Clypeal 

 extension usually bidentate. Mandible frequently with a small 

 preapical cusp. Head width 2.72 least distance between eyes (four 

 measured were 2.9, 2.65, 2.6, 2.75). 



Dorsum of pronotum with high, sharp transverse carina; punctures 

 small, evenly distributed, of third-degree density. Lateral pronotum 

 with a low, rounded anterior process; disc flat, microscopically 

 aciculate, without groove across its middle. Mesopleuron not any-

where masked under fine appressed hairs; primary punctures small, 

 usually separated by several times their average diameter; minute 

 punctures more numerous than primaries only on upper half and along 

 posterior slope. Hind tibia on inside with a naked longitudinal streak 

 that is moderately ridged on apical half; sensorium obscure. Tegula 

 black, opaque, glossy, without marginal groove. Forewing (fig. 1b) 

 strongly infumated; stigma nearly twice as long as wide; radial cell 

 greatly exceeds second cubital cell in lateral extension; second cubital 

 cell with its anterior section much longer than the posterior (average 

 of four defined in ratios of the first intercubital, listed clockwise: 

 1.0, 2.5, 1.85, 1.9). 



Dorsum of propodeum smooth, polished; areola with slightly con- 

 cave sides and broadly truncate apex, twice as long as apical width or 

 slightly less. Tergum 1 without a transverse carina, or at most with 

 an irregular poorly developed one in center of segment; preapical
