malar space hardly as long as basal width of mandible, weakly con- 

 stricted; mouth as broad as narrowest width of face; temples from 

 above nearly flat, oblique, about a third as long as short diameter of 

 eye; diameter of lateral ocellus fully three-fourths as long as ocell- 

 ocular line ; basal joint of flagellum little more than six times as long 

 as thick at apex. Thorax polished; anterior lateral margin of pro- 

 notum subangulate, carina moderately high, epomia strong, angulat- 

 ing the swollen humeral margin, groove along posterior margin fove- 

 oiate, the foveolation in middle prolonged into striations extending 

 into the scrobe; prescutum moderately high, lateral lobes flattened 

 above; scutellum not elevated; mesopleurum and sternum with 

 scattered punctures, prepectal carina incomplete above, the suture not 

 foveolate; metapleurum very coarsely diagonally rugose, the upper 

 division sparsely punctate ; propodeum rugose behind carina, smooth 

 with a few large punctures before, with a more or less nearly com- 

 plete narrow median longitudinal furrow, carina nearly straight, 

 spiracles large oval, apophyses long, stout, apically compressed, closer 

 to carina than to apex, hind femur one and a half times as thick 

 in middle as at apex, inner calcarium a little more than a third as 

 long as basitarsus; areolet short and broad, recurrent and nervulus 

 antefurcal, postnervulus broken at middle, nervellus above lower 

 third. Abdomen very minutely alutaceous, stout, second tergite not 

 or barely twice as long as broad at base, much shorter than first; 

 sheath very nearly as long as hind tibia. 



Head and thorax dark brownish piceous with the following mark- 

 ings whitish: Face, clypeus, very broad complete orbital ring, apex 

 of frontal horn, bases of palpi, annulus on flagellar joints 5-10; 

 propleura, broad anterior lateral and humeral margins of pronotum, 

 nearly the entire length of inner margin of lateral lobes of mesos- 

 cutum, mesopleurum, and sternum, except a streak along posterior 

 margin continuing above into the impression below subalar tubercle, 

 and reddish stains anteriorly on prepectus and in sternauli ; apex of 

 scutellum and the carinae, these two markings usually confluent; 

 postscutellum ; metapleurum except along suture dividing upper 

 and lower divisions and a spot near apex of lower division ; propo- 

 deum white with basal suture, median and two lateral stripes, and 

 a broad transverse band just behind carina and broadly confluent 

 with lateral stripes, piceous; this leaves two rounded white spots 

 basad of carina and confluent with the white of the lower division 

 of the metapleurum and two larger elongate marks on the apical 

 slope embracing the apophyses; legs ferruginous, all tarsi fuscous 

 at least apically, coxae whitish above, hind coxa with a piceous
