 very shallowly concave; frontal horn large conical, eyes nearly 

 parallel within and comprising much less than two-thirds total 

 width of head; face minutely alutaceous, impunctate, slightly swol- 

 len next to the eyes; occipital carina nearly parallel with posterior 

 margin of eye, hardly notched at its junction with hypostomal ca- 

 rina; temples from above oblique, about two-fifths as long as short 

 diameter of eye ; diameter of ocellus less than two-thirds as long as 

 ocell-ocular line. Pronotum with anterior lateral carina rather 

 low, epomia forming a carinate angle at anterior end of weltlike 

 humeral margin, lower half of posterior margin foveolate; lateral 

 lobes of mesoscutum longitudinally subimpressed ; subalar tubercle 

 not carinate; propodeum slightly impressed in basal middle, spira- 

 cles large oval, apophyses longer, slender, and slightly curved ; ner- 

 vulus antefurcal, postnervuLus broken above middle, nervellus at 

 lower fourth. Second tergite less than three times as long as broad 

 at base. 



Lower posterior orbits and cheeks also white; collar black; scu- 

 tellum white in middle but not at sides; propodeum black basad
