extremely dense, that of prosternura much more sparse. Head three- fonrths 

 wider than long ; front moderately convex, apical margin very broadly 

 rounded, narrowly sinuate at the sides before the eyes; the latter rather 

 large and prominent ; surface finely and evenly punctate, punctures round, 

 perforate, distant by about their own widths, interspaces nearly flat, shining ; 

 antennae as long as the head and protliorax together, basal joint strongly 

 flattened, somewliat lunate, about two-thirds . longer than wide, scarcely 

 longer than tlie next two together, second not one-half longer than wide, 

 about two-tliirds as long as the third, third scarcely perceptibly shorter than 

 the fourth and distinctly longer than the fifth, outer joints slender, one-hall 

 longer than wide, narrowed almost equally toward base, eleventh very 

 slender, finely acuminate at tip. Prothorax slightly wider than the medial 

 length ; sides nearly parallel and very feebly convergent in the anterior 

 third, broadly and feebly arcuate, broadly and rather stronglj' sinuate along 

 the exterior edges of the basal processes, the latter slightly projecting 

 laterally, very strong and acute, narrowly carinate internally and above ; 

 disk very strongly convex, rather coarsely punctate, punctures deep, the 

 larger separated by much more than their own widths, intervals flat, polished, 

 sparsely and much more finel}' punctate ; apex from above broadly and ex- 

 tremely feebly emarginate, about four-fifths as long as the width between the 

 apices of the basal processes. Scutellum longer than wide, broadly rounded 

 behind, sides straight, densely pubescent. Elytra as wide as the pronotum ; 

 sides parallel and extremely feebly arcuate for two-thirds the length from 

 the base, thence gradually convergent, ajiex obtusely rounded; disk three- 

 fourths longer than the head and prothorax together, much less convex than 

 the latter, about twice as long as wide, narrowly and deeply striate ; striae 

 distantly finely and scarcely perceptibly punctate, intervals very feebly 

 convex, densely minutely and rather evenly punctato-asperate, shining ; 

 humeral angles obsolete ; each elytron acutely rounded at base, lateral 

 portions within the processes of tlie ]>ronotum feebly sinuate ; striae termi- 

 nating before reaching the base. Abdonninal segments veiy finely and rather 

 closely punctate, first four sub-equal in length. Legs rather short, pubes- 

 cent; tibiae fimbriate externally along the entire edge with a double row of 

 sliort equal rather distant spinules. Length (i.2 mm.

The basal segments of the abdomen have a small discal impression 

 at each side. The S[)ecies is distingiiisiiable from OKritfis by its much 

 more robust form, more convex and shorter pronotum wliicii is less 

 densely punctate, and by its much more dense and conspicuous pubes- 

 cence, espiicially of the elytra and alidomen. In coloration and struc- 

 ture of the sculellum the two species are entirely different.
