])inictiiros most conspicuous behind tiie anterior angles, fine 

 at the base, on the basal ed^^c before the scuti'lUun are two 

 arched impressions tree of punctures ; the elytra, outer huuieral 

 stria apical and scarcely dimidiate, inner wanting, oblique 

 basal very fine and close to the first dorsal, dorsal 1-3 com- 



fdete, 4 apical but reaching the middle and it has a short 

 )asal apj)eiidage, 5 apical very short and somewhat puucti- 

 forni, sutural apical but reaching quite to the middle and 

 from the apex the striaj diverge from the suture, its base is in- 

 dicated by a puncture; the propygidium is distinctly punctured 

 at the sides and minute punctures are intermixed with the 

 larger ones, the minute punctures alone extend over the disc ; 

 the pygidium is similarly but less conspicuously punctured, 

 and on either side near the middle of the margin is a fovea; 

 the prostenium is bistriate, the striaj do not meet anteriorly 

 and they diverge posteriorly from the coxse to the base ; the 

 mesosternum is bisinuous anteriorly and narrowly transverse, 

 it posterior limit is marked by a bent not crenuhite stria. 



Differs from circulifrons, Mars., in size, more oval outline, 

 less convex form above, frontal stria less strong and not 

 semicircular, and the thoracic scutellar impression is distinctly 

 biarcuate and free of punctures.

 the stria, stria complete and straight anteriorly, epistoma 

 and mandibles also densely and rugosely punctured, the last 

 are not marginate; the thorax, lateral marginal stria ex- 

 tremely tine, external lateral ceasing behind the eye, interstice 

 narrow, intern;il, feebly sinuous laterally, complete behind 

 the head, and distinctly sinuous behind the eyes, interstice 

 rather wide and punctulate, with some irregular strisB or 

 rugosities at and behind the anterior angle, the sides are 

 micro.<copically punctulate ; the elytra, striaj, external 

 humeral wanting, internal apical and dimidiate, oblique basal 

 extends outwardly beyond the inner humeral, dorsal striai
