154 MEMOIRS ON THE COLEOPTERA 



toward the humeri; hairs sparse and extremely short; head scarcely 

 two-thirds as wide as the prothorax, rather finely and closely 

 punctate, the eyes large but not very prominent; antennal club 

 broad and abrupt, oblong; prothorax large and strongly convex, 

 two-thirds wider than long, the sides perfectly parallel and evenly, 

 rather strongly arcuate throughout the length; punctures strong and 

 close-set, becoming finer medially; basal strioles extremely minute 

 and barely at all indicated; scutellum small, transverse; elytra short, 

 one-half longer than wide, obtusely parabolic in about apical half, 

 the sides thence parallel and but feebly arcuate to the base, two and 

 one-half times as long as the prothorax, the punctures rather small 

 and not very close-set, evenly lineate, obsolescent apically; under 

 surface very closely punctulate on the abdomen. Length 2.35 mm.; 

 width 1.1-1.15 mm - Indiana, Levette collection, .laticollis n. sp. 



Prothorax never wider than the elytra, the latter black, with rufous 

 areas 5 



5 Elytra each with a rufous area at the humeri but not at apex. Body 

 ferruginous in great part, blackish beneath, the elytra when fully 

 colored black, excepting the humeral spot, but occasionally the entire 

 body and elytra is paler brown, with still faintly paler humeral 

 region probably from immaturity; head finely, densely punctate, 

 the eyes moderate and not very prominent; antennal club broadly 

 oval; prothorax much shorter than in quadrimaculata, two-thirds to 

 three-fourths wider than long, the sides parallel to very feebly 

 oblique, never more than very feebly arcuate, generally slightly 

 more so apically, the punctures well separated, rather strong and 

 close laterally; elytra three-fifths to two-thirds longer than wide, 

 generally very slightly wider than the prothorax, parabolic in form 

 in about apical half, with the punctures well separated in tolerably 

 regular series, except suturally, the sculpture obsolescent apically 

 as usual; under surface finely, closely punctulate. Length 1.7-2.75 

 mm.; width 0.8-1.2 mm. California (Lake Co. to Sta. Cruz Mts.).

Elytra maculate as in the preceding, the form still more elongate and 

 materially larger in size, the hairs small, still sparser and less evident; 

 color black above and shining, the head and pronotum obscure, the 

 latter gradually blackish toward base; under surface nearly black, 

 the pubescence of the abdomen rather dense and conspicuous; head 

 nearly as in californica; prothorax similar in general outline and 

 sculpture but not so abbreviated, only about three-fifths wider than 

 long; apex arcuate, sinuate toward the moderately prominent angles; 

 scutellum less abbreviated; elytra notably longer, three-fifths to 

 three-fourths longer than wide, not wider than the prothorax, similar 

 in general outline and sculpture to those of californica; abdominal 

 punctures fine and close, the apical segments generally pallescent. 

 Length 2.7-3.4 mm.; width 1.15-1.25 mm. California. Two 

 examples, said by Dunn to have been taken in the vicinity of San 

 Francisco elongata n. sp.
