 a,nd distinctly punctate, impressed on each side of middle; malar 

 space much shorter than basal width of mandible, constricted, 

 mouth hardly as broad as narrowest width of face; temples in side 

 view slightly convergent above with posterior margin of eye, occipital 

 carina low, not reaching hypostomal carina, from which its lower end 

 is separated by a broad, shallow groove, hypostomal carina rather 

 high; temples from above flat, very weakly oblique, barely a fourth 

 as long as short diameter of eye; diameter of an ocellus about two- 

 thirds as long as ocell-ocular line. Thorax polished, anterior lateral 

 margin of pronotum with a rather prominent elevation, the carina 

 high, epomia short but distinct; prescutum strongly convex, lateral 

 ]obes slightly flattened; scutellum high, compressed; mesopleurum

 nearly twice as thick in middle as at apex, inner calcarium a little 

 more than a third as long as basitarsus ; areolet of normal form, recur- 

 rent antefurcal, nervulus interstitial, postnervulus broken in middle, 

 nervellus at lower third. Abdomen polished, minutely alutaceous be- 

 yond second tergite, second tergite about four times as long as 

 broad at base, as long as first, broadly constricted near base ; sheath 

 not quite so long as hind tibia. 



Head black ; clypeus, mandibles, and maxillary palpi white ; labial 

 palpi testaceous; annulus from middle of fourth joint of flagellum 

 to eleventh joint; thorax and legs ferruginous, hind femur dark
