occipital carina broadly incurved and subangulate at middle; 

 length of exposed cheek margin one and a half times the 

 distance from ocelli to eyes, the latter distance but little less 

 than that from ocelli to occipi^ial carina and subequal to long 

 diameter of an ocellus; surface of vertex smooth and shining; 

 ocelli large, separated by about half their long diameter ; surface 

 at sides and in front of anterior ocelli shallowly, radiately 

 wrinkled. 



Face about as long as wide above at the deeply emarginate 

 eyes; eye margins strongly outcurved below; surface strongly, 

 medially, subumbonately raised on upper half, on either side a 

 short depressed area above clypeal pit; face shallowly, trans- 

 versely wrinkled, discontinuously on umbo ; clypeus short, trans- 

 verse, basal suture subobsolete, clypeal pits close to eyes ; mouth 

 opening very large and broad, broadly elliptical, lower clypeal 

 margin nearly straight; entire surface of mandibles strongly, 

 sparsely punctate. 



Head viewed from side with face somewhat prominent above ; 

 cheeks broad throughout, half width of eye, outer margin parallel 

 with eye margin, surface smooth and shining; malar space very 

 small, its length less than half width of cheek, its surface together 

 with a narrow curved area about lower margin of eye, cross- 

 striate; eye short and very broadly subelliptical, broadest on 

 lower half. 



Mesonotum deeply trilobate, smooth and shining, notauli deeply 

 impressed, crenulse apparent only near anterior extremities, ter- 

 minating posteriorly on the sides of a long, narrow, deep median 

 furrow on posteromedian area. Scutellum anteriorly with two 

 large and rather shallow foveas, separated by a sharp median 

 carina; posterior disk of scutellum smooth. Postscutellum with 

 two small median f oveae separated by a sharp carina ; lateral areae 

 rugose. Metanotum shallowly reticulate-rugose on anterior 

 third, very strongly, but irregularly, transversely rugose on 

 posterior two thirds, with a complete, but partly sinuous, median 

 carina ; below the elliptical spiracle a longitudinal carina passes 

 to anterior border, while posteriorly a foveated furrow extends 

 to posterior border; metapleura shining, obscurely roughened; 

 mesopleura smooth and shining, with a short crenulated furrow 

 within an oblique discal impression in lower half; a few short 

 vertical rugae below wing. 



Abdomen pedicellate, about twice the length of head and thorax 

 together, gradually widened to third tergite, six tergites fully 

 exposed; first tergite very slender from base to spiracles, which
