wider, ogival at tip, the sides broadly 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 2.72 mm. California (Mokelumne Hill, Cala-

Form elongate-oval, rather shining, colored nearly as ^in blaisdelli,^ 

 the under surface and legs brighter rufous and more polished ; 

 head rather coarsely, closely punctured, the sides strongly converg-

 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; scutellum similar ; elytra with 

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

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

 times as long as the prothorax and scarcely wider, evenly ogival 

 toward tip, the sides feebly arcuate, more strongly at base, the
