 throug-hout. 



Head twice as wide as long, feebly convex, more or less impressed 

 laterally and along the frontal suture, the latter more or less obsolete ; 

 surface irregularly and sparsely punctate at middle, also on the 

 vertex, more densely and coarsely so lateralh^ and on the epistoma. 

 Antennce rather long, quite slender, outer four joints feebly com- 

 pressed and distinctly and gradually incrassate, third joint scarcely 

 as long as the next two taken together, fourth just the least longer 

 than the fifth, the latter to the seventh inclusive subequal in length, 

 the seventh slightly broadened and subtriangular, eighth just the least 

 shorter and more or less triangular, ninth triangulo-oval and feebly 

 transverse, tenth transversely oval, eleventh transversely suboval. 



Pronotum slightly transversely suboval, widest at the middle, about 

 or a little more than a third wider than long; disc moderately convex, 

 distinctly arcnately declivous later<dly and at the apical angles, 

 sparsely, distinctly, and very irregularly punctate, with scattered 

 impunctate areas, punctures coarser and denser laterally on the de- 

 clivities, where each bears a moderately long erect seta; apex sub- 

 truncate in circular arc, finely and more or less obsoletely margined; 

 sides more or less evenly and moderately arcuate, somewhat straight 

 and convergent posteriori}^, feebly or not at all sinuate before the 

 basal angles, marginal bead fine and entire; hase very feebly rounded 

 and finely beaded, about a fifth to a fourth wider than the apex and 

 equal to or slightly greater than the length; apical angles obtuse, not 

 in the least prominent, and more or less feebly rounded ; basal angles 

 obtuse or minutely rectangular and just the least prominent. 



Pi'oplemxe opaque, sparsely punctate, each puncture witli a moder- 

 ately long, erect, and brownish seta. 



Elytra oval, not over one-half longer than wide, widest at the mid-

 base ; humeri rounded ; sides evenly arcuate, apex not very narrowly 

 rounded and not in the least produced ; disc almost evenly convex 

 from side to side, dorsum scarcely flattened, arcuately declivous 

 posteriorly ; surface punctate, punctures coarse and impressed, rather 

 dense and scarcely arranged in series, at the sides and apex the 

 punctures are more irregular, submuricate, each with a rather short 

 suberect seta, wdiich become less evident on the dorsum. 



EpiplewrcB rather Avide, gradually nari'owing from base to apex, 

 superior margin rather feebly and broadly sinuate beneath the 

 humeri and not visible from above; surface smooth, sparsely and 

 coarsel,y punctate.
