wider, ogival at tip, the sides broadl}^ arcuate, the punctures only 

 moderately coarse, close-set but shallow in slightly uneven and 

 unimpressed series, the irregular interstitial series fine and still 

 feebler; abdomen finely, sparsely punctured medially. Length 

 6.4 mm.; width 2.73 mm. California (Mokelumne IUll, Cala-

 three-fourths wider than long, the apex broadly sinuate and three- 

 fourths as wide as the base, the sides more converging and a little 

 more strongly, subevenly arcuate throughout, the punctures only 

 moderately small, deep and rather close-set, becoming gradually 

 coarser, densely crowded and longitudinally confluent laterally, 

 the surface broadly and feebly impressed before the basal margin, 

 except laterally as in blaisdelli ; scutelluin similar ; elytra with 

 rather fine, feeble and very close-set punctures in uneven unim- 

 pressed series, becoming coarse very near the base, the interstitial
