divided from front by an irregular shallow impression, this 

 impression obsolete in middle; median part not divided from 

 wings, truncate; wings advanced, rounded at apex and externally, 

 inner side gently oblique; supra-antennal plates short, wide, 

 rounded externally, projecting strongly beyond clypeal wings; 

 eyes deeply embedded in orbits behind, small, convex, hardly 

 more prominent than supra-antennal plates; orbits projecting 

 strongly from sides of head behind eyes; facial carinpe strongly 

 d(?veloped, converging roundly in front and reaching clypeus. 

 Mandibles short. Labrum 5-setose. Labial palpi stout; penulti- 

 mate joint not longer than terminal; this thick, obtuse at apex. 

 Antennpe short, moniliform; third joint shorter than second; joints 

 5-10 short, quadrate. Prothorax subquadrate (2-3* x 2-45 mm.), 

 widest just before posterior angles, a little narrowed anteriorly 

 (ant. width 2-15 mm.), convex, very declivous to base; sides 

 lightly and widely sinuate, rounded to anterior angles; anterior 

 margin widely and deeply emarginate; anterior angles distant 

 from neck, obtuse but marked; posterior angles rounded, not 

 marked; basal curve very short; lateral channel well developed; 

 median line strongly impressed, reaching base; anterior line 

 distinct, very near margin; border narrow, not upturned at 

 posterior angles. Elytra oval (4-5 x 2"5 mm.), widest a little 

 behind middle; sides strongly rounded; shoulders rounded; apex 

 widely rounded; strite deep, simple, seventh hardly less deeply 

 impressed than others. Prosternum with intercoxal part wide 

 anteriorly, non-sulcate on base; episterna very feebly transversely 

 striolate, overhanging near anterior angles. Anterior femora 

 short, wide, strongly arcuate above, rounded not channelled 

 below; tibiae rather wide, apex short, wide, curved, first external 

 tooth wide, prominent, upper tooth wide, not prominent, inner 

 apical spine thick, truncate, longer than apical digitation (as long 

 as three basal joints . of tarsus), upper internal spine finely 



* This is the length in the mitlclle; fiotn anterior anj^le to base the
