out below and not reaching the rather low hypostomal carina; 

 temples from above oblique, weakly convex, about a third as long 

 as short diameter of eye. Thorax polished ; anterior lateral margin 

 of pronotum with a rounded elevation over the top of which runs 

 the moderately strong carina, epomia wanting; mesoscutum (badly 

 broken by pin) apparently with prescutum low and lateral lobes 

 flattened; scutellum not elevated and hardly compressed; meso- 

 pleurum with weak scattered punctures, subalar tubercle not cari- 

 nate, prepectal carina complete, the furrow foveolate above; lower 

 division of metapleurum coarsely rugose punctate, upper division 

 coarsely and sparsely punctate; propodeum smooth before carina, 

 coarsely rugose behind, medially impressed basally, the impression 

 bounded laterally by carinae, basal carina straight medially, spiracles 

 nearly circular, pleural carina distinct, apophyses rounded tuber- 

 culiform, a little closer to carina than to apex ; hind femur twice as 

 thick in middle as at apex, inner calcarium two-fifths as long as 

 basitarsus; areolet small, broad, recurrent not far behind middle, 

 nervulus antefurcal, postnervulus and nervellus broken about at 

 middle. Abdomen polished; first segment stout with spiracles at 

 apical two-fifths, second tergite three times as long as broad at base 

 and as long as first ; sheath much shorter than hind tibia. 



Head black and white with the following white: Face, clypeus, 

 mouth parts, broad, complete orbits, frontal horn, scape at apex 

 below, and annulus on flagellar joints 5-11; pronotum and meso- 

 scutum and lateral areas of scutellum black, anterior and humeral 

 margins of pronotum, scutellum and its carinae, and tegulae white; 

 thorax otherwise ferruginous with subalar tubercle, a poorly defined 

 spot before middle coxa, and the apophyses whitish; legs ferrugi- 

 nous, coxae whitish above, front and middle tarsi fuscous, hind tarsi
