Temples strongly narrowed and weakly convex; face medially some- 

 what elevated, very finelj^ shagreened and sparsely punctate fully a 

 half wider than frons, slightly convergent below, about as wide as 

 long; clypeus rather long, flat, apically broadly truncate, shagreened 

 and with scattered coarse punctures; eyes rather deeply emarginate; 

 frons flat, transversely aciculate; ocelli very large, contiguous with 

 the eyes; antennae slender, middle joints more than twice as long as 

 thick, basal flagellar joint on its shorter side about a fourth longer 

 than second. Thorax subopaque; mesoscutum granular, notauli 

 long; scutellum carinate to apex, the space between carinae nar- 

 row and strongly convergent posteriorly; mesopleurum finely and 

 rather densely punctate; metapleurum indistinctly obliquely striate; 

 propodeum rather strongly rounded from base to apex, transversely 

 striate, apophyses strong, spiracles long oval; areolet subquadrate; 

 second recurrent strongly and almost evenly curved throughout, 

 interstitial; nervulus shortly postfurcal (about one-third its length) ; 

 postnervulus broken at upper third; nervellus broken at a slightly 

 acute angle at about its upper two-fifths; hind femur slender, barely 

 a fourth shorter than tibia; tarsi very slender, apical joint of middle 

 tarsus very slender, curved, iiiWy as long as second joint; claws very 

 long, nearly straight to near apex, with about seventeen large teeth. 

 Abdomen rather slender; first tergite four and one-half times as long 

 as wide at apex, spiracle at basal third ; second tergite two and one- 

 half times as long as wide at base, sides weakly divergent, 



Flavo-testaceous ; head, except occiput, yellow, vertex slightly 

 piceous; antennae testaceous, fuscous apically; thorax paler laterally 

 and along margins of mesoscutum and scutellum; legs coneolorous, 

 tarsi stramineous.

 that of middle leg being only about as long as the third joint, and 

 the claws very densely pectinate throughout.
