margins broken at several points by rugse ; posterior lateral arese 

 with strong, blunt prominences from which radiate rugae; spir- 

 acle small and round; lateral carina complete, though irregular; 

 metapleura smooth with a somewhat rugose median ridge poste- 

 riorly; mesopleura smooth and with a short, sharply impressed, 

 oblique, noncrenulate discal furrow. 



Abdomen longer than head and thorax together, sessile, broad, 

 gradually widened to third segment; first segment but little 

 wider at apex than at base, length about one and one-half times 

 width at apex ; second about as long as first but wider, gradually 

 widening apically, length and apical width subequal ; third much 

 shorter than second and twice as wide as long; fourth, fifth, 

 and sixth subequal in length, slightly shorter than third, and 

 successively narrower ; seventh segment very short, its hind mar- 

 gin slightly incurved, the subangulate point of eighth a little 

 exposed; all tergites coarsely, sharply, longitudinally striate, 

 minutely reticulate-punctate between the striae; sculpturing on 

 sixth segment distinct only at base; median carina distinct only 

 on first two tergites; first suture impressed only at middle; 

 second suture narrowly and slightly impressed; third, fourth, 

 and fifth sutures deeply impressed and strongly crenulate. Hind 

 tibiae with two straight, hairy spurs, which are about as long as 

 fourth tarsal joint. 



Stigma long, rather narrow, about five times as long as wide, 

 widest and obtusely angled at two fifths of lengih from base 

 where radius is inserted ; thickened first abscissa of radius about 

 half length of second ; second cubital cell nearly twice as long as 

 wide, not narrowed apically; first transverse cubitus strongly 

 oblique, second slightly so and decolored; first recurrent vein 

 nearly straight, entering^rst cubital cell a short distance before 

 apex; the parallel vein inserted at lower third; submedian cell 

 a little longer than median. Radius of hind wings curved

 of flagellar joints one and one-half times the width. Maxillary 

 palpi normal, short and slender.
