 at apex, the punctures even, rather fine but strong and quite sparse ; pubescence 

 coarse, yellowish-cinereous in color and conspicuous ; male characters nearly as 

 in lacustris, the fifth segment more feebly impresso-beveled and the glabrous area 

 of the first less defined. Length 2.0-2.15 com.; width 1. 5-1. 65 mm. Cali-

51 — Pronotum impunctate at any part, the sides continuous with those of the elytra, 

 strongly convergent, evenly and rather strongly arcuate ; elytra distinctly longer 

 than wide, rather strongly but not closely punctate, the vestiture somewhat 

 whitish, coarse, not very abundant but rather conspicuous. Length 2.15 mm.;

Pronotum distinctly but finely punctate, the punctures somewhat larger and more or 

 less close 'Set toward the sides, the latter not quite continuous with those of the 

 elytra, less strongly convergent, subevenly and moderately arcuate 52 



52 — Elytra scarcely as long as wide, strongly, evenly but unusual y sparsely punc-

Elytra fully as long as wide, somewhat less obtuse behind, rather strongly, evenly 

 punctate, the punctures moderately close-set, the pubescence shorter, finer, darker

54 — Large, strongly convex, polished, the prothorax moderate in size, much narrower 

 than the elytra, the sides strongly discontinuous, moderately convergent, evenly and 

 moderately arcuate, the punctures fine and sparse, closer toward the sides ; elytra 

 as long as wide, not very coarsely but deeply, evenly and rather sparsely punc-
