not very narrowly rounded; disc moderately to rather strongly 

 convex on the dorsum, sides not broadly rounded, inflexed portions 

 scarcely arcuate, arcuately declivous posteriorly; surface irregularly 

 and quite densely, more or less distinctly subasperately and muri- 

 cately punctate, sculpturing not strong, simple central^ and not 

 distinctly granulate laterally and on the apex. 



Epifleurm moderately wide, gradually narrowing from base to 

 apex, superior margin not strong and almost straight beneath the 

 humeri; surface smooth, im^^unctate toward base, obsoletely and 

 sparsely punctate toward ajjex. 



Sterna. — Prosternum scabrously rugoso-punctate ; meso- and meta- 

 sterna more or less shining, glabrous and rugoso-punctate. 



Paraflevrm rather densely, more or less evenly, and somewhat 

 coarsely punctate. 



Abdomen shining, sparsely and finely punctate, more or less 

 rugulose. 



Legs rather short and somewhat slender; anterior femora mutic 

 and not noticeably sinuate; tibial spurs rather slender and moderate 

 in length, similar in the sexes; anterior spurs of the protibise slightly 

 longer than the posterior; anterior and middle tarsi dissimilar in 

 the sexes. 



J/«7e.— Oblong-ovate, somewhat slender. Antennae reaching a little 

 beyond the base of the prothorax. Elytra evenly and arcuately de- 

 clivous posteriorly. Abdomen slightly oblique apically, moderately 

 convex, segments one and two broadly impressed at middle. First 

 three joints of the protarsi not noticeably thickened and clothed with 

 golden pubescence beneath, surface of the pads flat; first two joints 

 of the mesotarsi similarly pubescent, first joint in apical half, the 

 second with a much smaller tuft at tip. 



Female. — Distinctly robust. Antenna? about attaining the base of 

 the prothorax. Elytra broadly oval, arcuately and more or less verti- 

 cally declivous behind. Abdomen horizontal and strongly convex. 

 First two joints of the anterior and middle tarsi a little more pubes- 

 cent than usual beneath, grooves not evident. 



Measurements. — Males: Length, 13.5-14 mm.; width, G.5-6.5 mm. 

 Females : Length, 14-17 mm. ; width, 7.5-8 mm. 



Genitcd characters^ male. — Edeagophore flattened oblong-ovate, 

 acutely pointed at apex and scarcely arched. 



Basale oblong-suboval, moderately convex, sides feebly arcuate and 

 nearly parallel. 



Apicale triangular. Surface very moderately convex, without 

 groove ; sides briefly arcuate at base, thence broadly and more or less 

 strongly sinuate, so that the apex appears more or less attenuated in 

 apical half; base evenly rounded and scarcely lobed at middle.
