turing, except fori lateral grooves on posterior half, which are some- 

 times continued anteriorly by irregular, interrupted gouges. Ter- 

 gites with wide impunctate belts across their middles interrupted 

 medially by sparse punctures; impunctate apices at least one-fourth 

 the punctata width of the tergite. Pygidium rugoso-punctate on 

 upper half; impunctate apex strongly wrinkled and shagreened. 

 Length, 9.5 to 11 mm. 



Male. — Vertex with punctures of first-degree density between and 

 behind ocelli forming a well-defined patch on either side of which are 

 nearly impunctate areas crossed by a series of punctures of second- 

 degree density. Front obscurely shagreened, with a vague, medial 

 impunctate stripe; primary punctures rather small, and very densely 

 distributed over lower front and extending on to the preocellar reg- 

 ion, and leaving no impunctate interspaces as broad as an ocellus; 

 secondary punctures scarcely as numerous as primaries, extending 

 upward over lower half laterally, but rising higher on center, where 

 they nearly reach the lowest ocellus. Antennocular distance much less 

 than width of antennal fossa. Clypeal extension with its width two- 

 thirds the clypeoantennal distance ; apex masked with appressed hairs, 

 acutely emarginate, only the two extreme apical points impunctate. 

 Pronotum with punctures small, shallow, without distinct outlines 

 and largely of third-degree density, without much tendency toward 

 rows; secondary punctures present antero-medially, though difficult 

 to distinguish ; side of pronotum weakly striate, with a tapering me- 

 dian groove crossed by diagonal rugulae. Mesepisternum with pri- 

 mary punctures large and not clearly outlined, of first-degree density 

 on upper disk, becoming thinner behind and below ; secondary punc- 

 tures almost lacking, except on posterior slope. Scutellum with im- 

 punctate apex not as wide as the lowest primary punctures. Metano- 

 tum densely and coarsely punctate, the primary punctures nearly as 

 large as the largest of the scutellum and covering an area exceeding 

 that of the intei-spaces. Wings hyaline ; radial cell exceeding second 

 cubital cell. Propodeum with its areola slightly longer than wide, 

 with moderately converging sides, enclosed area and disk outside of 

 areola reticulate; side, on its lower portion, polished anteriorly, mi- 

 nutely setulose posteriorly; posterior aspect granulate, the median 

 carina complete or nearly so. First tergite with a preapical band 

 having an irregular, impressed anterior border and separate punc- 

 tures of nearly uniform width on posterior border. First sternite 

 with impunctate, polished disk, coriaceous to sparsely punctate ante- 

 riorly, lateral grooves on posterior half, median keel on upper half. 

 Tergites 3 to 5 with punctures sparse, with indefinite hind margins, 

 and with impunctate apex medially six times the diameter of largest 

 adjacent primary puncture. Length, 9 mm. 



Distribution. — Assam, India.
