than the fifth, the hitter, sixth and seventh snbeqnal and each about 

 as long as wide, eighth, ninth, and tenth transverse and gradually 

 increasing in width, eleventh narrower than the tenth, triangulo- 

 ovate and about as long as wide. 



Pi'onotum one-third to one-half wider than long, widest at the 

 middle ; disc rather strongly convex and moderately declivous at the 

 apical angles, coarsely, more or less contluently and cribrately punc- 

 tate, with two deep oval fovea? occupying nearly the whole of the 

 median line, sometimes forming a deep median groove, or frequently 

 entirely absent; apex deeply and broadly emarginate, beaded laterally, 

 obsoletely so at middle three-fifths; sides moderately strongly arcuate 

 to basal ninth, thence briefly and strongly sinuate to base, here the sides 

 are divergent or subparallel, scarceW at all sinuate behind the apical 

 angles, marginal bead distinctl}^ serrulate anteriorly, posteriorly 

 obsoletely so; hase transverse, scarcely beaded; apical angles large, 

 prominent anteriorly, subacute; basal angles minute, acute, and promi- 

 nent externally or rectangular. 



Propleune more or less convex, but not prominently so, smooth, 

 more or less granulate on the acetabular convexities and posteriorly, 

 sometimes rugulose. 



Elytra elongate oval, less than twice as long as wide, widest at the 

 middle; hase not margined nor adapted to the contiguous prothoracic 

 base, which is slightly wider; humeri obsolete; sides evenly arcuate 

 and quite evenly and gradually narrowing from the middle to apex, 

 the latter slightly produced and rather narrowly rounded ; disc quite 

 evenly and rather strongly convex from side to side, somewhat quickly 

 and arcuately declivous posteriorly, but slightly and broadly sinuate 

 before the moderately oblique apex (view^ed from the side), the suture 

 and four smooth costfe each side acutely elevated, sutural costa feeble 

 and evatiescent on apical declivity, the humeral and subhumeral meet- 

 ing anteriorly on humeral region, the subhumeral free and obsolete 

 before the apex, first discal free at both extremities being evanescent 

 on apical declivity, second discal uniting with the humeral before 

 the apex, point of imion not tuberculate nor prominent; each in- 

 terval broad and apparently biseriately subfoveolate, the foveola? 

 more or less indistinctly marked, more or less feebly transversely 

 coalescent, irregular in the outer two intervals, the minute subsquami- 

 form setge scattered independently of the pits. 



E pipleurw narrow, overlapped at middle by the metasternal pieces 

 and first abdominal segment, horizontal in apical two-thirds; surface 

 smooth, obsoletely punctate. 



Sterna sparsely, coarsely, and more or less moderately punctate; 

 mesosternum deeply and broadly concave, sides prominent; metaster-
