more curved than apical, surface laterally concave; clypeal pits 

 distant from eyes two and one-half times their diameter. Head 

 viewed from side with prominent, evenly curved face margin, 

 clypeus not projecting; cheeks narrow, about one third the width 

 of eyes, outer margin parallel with eye margin; malar space 

 small, its length subequal to width of cheek; eyes very large, 

 very broadly and bluntly elliptical. Maxillary palpi reaching 

 tegulae, third joint longest, somewhat widened at middle, fourth 

 shorter and somewhat widened on basal half, fifth and sixth 

 progressively shorter, slender and terete. 



Antennse about as long as entire body; scape subcylindrical, 

 slightly narrowed to base, one and one-half times as long as wide 

 apicaily; funicle large, more than half length of scape, sub- 

 cylindrical, slightly narrowed apicaily; middle flagellar joints 

 about twice as long as wide. 



Mesonotum very long, trilobed, the notauli sharply impressed 

 and regularly crenulate as far back as posterior median plane 

 area, the latter with a lanceolate median groove; entire surface 

 of mesonotum smooth and shining. Scutellum anteriorly 

 quadiifoveate, separating carinas low and equally strong; disk 

 of scutellum smooth. Postscutellum very broadly quadrifoveate. 

 Metanotum very coarsely and openly reticulate-rugose, with a 

 narrow, median, lanceolate groove, which is crossed by several 

 rugse; metapleura and mesopleura smooth, the latter broadly 

 depressed and irregularly wrinkled below wing, disk with a 

 broad, oblique, curved, deeply impressed, crenulate furrow; 

 spiracle large and subcircular. 



Abdomen half again as long as head and thorax together, 

 broadly sessile, six tergites fully exposed, third tergite broad- 

 est, all strongly sculptured; first tergite with length nearly one 

 and one-half times the apical width ; second tergite about as long 

 as first, little widening apicaily, sides straight, length subequal to 

 apical width; remaining tergites subequal in length, together 

 somewhat more than half length of second and progressively 

 narrower, sixth with a concave apical margin; a very narrow 

 point of seventh segment projecting beyond sixth; first and 

 second tergites very coarsely and longitudinally striate, striae 

 on second segment somewhat oblique; striation on remaining 

 tergites finer, thicker, more irregular, and strongly oblique; 

 second suture impressed, but completely connate, the striae 

 continuous across it; remaining sutures normal, but followed 

 by deeply impressed, crenulated borders ; first and second tergites 

 with a strong median carina. Hypopygium large, as long as
