to width; clypeal pits small, distant from eyes about five times 

 their diameter. Mandibles very short, swollen atjbase, outwardly 

 roughened. Head viewed from side with face margin slightly 

 elevated below antennae, then straight to the nearly plane clypeus ; 

 cheek very narrow, one fourth width of eye, outer margin parallel 

 with eye margin ; malar space large, its length one and one-half 

 times the width of cheek; eye very large, broadly elliptical, 

 slightly narrower on lower fourth. Maxillary palpi reaching 

 tegulse, slender and terete. 



Antennae subequal in length to entire body; scape short and 

 thick, length somewhat greater than width at widest part, and 

 slightly narrowed proximad ; f unicle little more than half length 

 and width of scape; middle flagellar joints about twice as long 

 as wide. 



Mesonotum obscurely trilobed, though long at middle, notauli 

 very superficial, broad, and obscurely crenulate, rather widely 

 separated posteriorly; surface of mesonotum shagreened, pos- 

 terior median area plane and rugulose. Scutellar fovese ap- 

 parently three, the median carina nearly obsolete, but with two 

 distinct lateral carina, thus forming one small median and two 

 larger lateral fovese ; disk of scutellum shagreened. Metanotum 

 coarsely, but shallowly, rugose and with a complete, but rather 

 weak, median carina ; disk of metapleura anteriorly shagreened, 

 posteriorly rugose ; mesopleura radiately rugose from above, and 

 anteriorly with spiracle subcircular and with a continuous, sinu- 

 ous, longitudinal, sutural carina passing beneath it; an irreg- 

 ular sternopleural carina, a small area on disk below and 

 posteriorly shagreened, but disk entirely without distinct groove 

 or depression. 



Abdomen about as long as head and thorax together, broadly 

 sessile, broadened to third segment, remaining three visible seg- 

 ments very rapidly shorter and narrower and smooth and shin- 

 ing; first tergite rapidly broadened apically, length and apical 

 width subequal, basal width more than half the apical width; 

 second tergite slightly longer than first, its length little less 

 than apical width; third tergite about three fourths as long as 

 second, its length about half apical width; first and second ter- 

 gites strongly, longitudinally striate, third less strongly so and 

 apically with the striae strongly curved toward lateral margin, 

 median apical border smooth ; a median carina on first and second 

 tergites and on basal two thirds of third tergite ; second suture 

 shallow, curved, and completely carinate, the striae continuous 

 across it; remaining sutures normal. 



Stigma large and triangular, its length about three times
