Length 14 to 20 mm., width 7 to 11 mm. Oblong-oval, convex, 

 shining, reddish bro%Yn to piceous. Clypeus apically bidentate, the 

 erect triangular teeth widely spaced, separated by their basal width 

 or more, surface finely closely rugose, the posteriorly directed frontal 

 carma sinuate, strong and thin, widely interrupted at middle, joining 

 lateral carina at sides. Head similarly rugose back of the carina, 

 breaking into moderate punctures just in front of the smooth, shining 

 occiput. Pronotiun convex, with anterior and lateral margins as 

 usual, base without margin, weakly sinuate, apical denticle small with 

 a small, usuallj^ shallow depression behind it less than one-fom-th 

 the pronotal length; sm-f ace very evenly, finely to moderately punctate 

 throughout, punctm-es everywhere separated by one to four times 

 their diameters, the apical depression with a trace of rugose sculpture. 

 Scutellum smooth, rarely with a few minute punctm-es. Elytra 

 slightly wider behind the middle, moderately coarsely punctate, the 

 punctm*es finely annular, very fine punctures intermLxed throughout, 

 the oblique geminate striae deep, theu- punctm-es usually separated 

 hj less than their diameters, all punctures finer laterally and apically. 

 Pygidium coarsely, deeply punctate, slightly smaller apically, generally 

 separated by one or two diameters. Underside anteriorly moderately 

 hairy, prosternal process behind anterior coxae apically flat to convex, 

 narrowly nude, the long stiff hairs encroaching from back and sides. 

 Anterior tibia smooth outside the longitudinal row of coarse, setigerous 

 punctures, claws normal. Male aedeagus distinct (see fig. Qa).
