232 MEMOIRS ON THE COLEOPTERA 



middle of the elytra, the latter evenly tapering from base to apex, 

 not more than one-half wider than the prothorax and fully four 

 times as long, the sutural angles finely and minutely dentiform; 

 under surface densely yellowish-pubescent. Length (cf) 10.5 mm.; 

 width 3.0 mm. California (Sta. Barbara), Dunn., .cuneata n. sp. 



Tempora nearly as in the preceding but more retracted because of the 

 more prominent eyes; body stout, more convex than in any of the 

 preceding, with nearly similar sculpture, black, the elytra pale tawny- 

 yellow to slightly piceous, always with a black marginal streak 

 behind the humeri, the apices constantly rather broadly margined 

 with black; pubescence more developed than in any other species, 

 very long dense coarse and golden-yellow to fulvous anteriorly, 

 especially in the female, short and more cinereous on the elytra, 

 the longitudinal thoracic heaps of pubescence less widely separated 

 than in cuneata, the tempora differing in being also densely yellow- 

 * pubescent like the rest of the surface; pale basal area of the elytra 

 less distinct because of the paler color, the elytra but feebly tapering 

 in the male; under surface densely cinereo-pubescent, less so in the 

 male, the parapleura conspicuously albido-pubescent; legs colored 

 nearly as in cuneata. Length 8.0-10.0 mm.; width 2.5-3.0 mm. 

 California (Mokelumne Hill, Calaveras Co.), Blaisdell. 



auricollis n. sp. 



6 Tempora finely, closely punctured, not or scarcely more shining than 

 the rest of the surface. Body slender, moderately convex, black, 

 the elytra pale yellow, tipped with black, the legs colored as in 

 basalis; head and prothorax finely, densely punctate, the former with 

 short and moderately close, the latter with barely longer and closer 

 and almost uniformly distributed, dark yellow pubescence, not dis- 

 tinctly heaped up near the feebly depressed median line; tempora 

 arcuately converging behind the distinctly prominent eyes; antennae 

 slender, black, the basal joint yellow, the third not quite so long as 

 the fifth ; prothorax rather longer than wide, strongly, subcylindrically 

 convex, with a short broad impunctate spot behind the centre; 

 elytra less than twice as wide as the prothorax, the punctures notably 

 strong throughout, finer apically, rather coarse basally; under surface 

 not densely cinereo-pubescent, the parapleura with dense white 

 decumbent hairs as usual. Length 6.8 mm.; width 1.75 mm. 

 California (Calaveras Co. the locality unrecorded). 



elegantula n. sp. 



Tempora almost completely impunctate, highly polished and conspicu- 

 ous 7 



7 Form slender, rather convex, shining, deep black, the elytra with four 

 small red spots at base, the legs black, the anterior femora and tibiae 

 and the middle femora basally red; antennae rufo-piceous, the two 

 basal joints entirely testaceous; punctures of the head and pro- 

 thorax small, very dense on the former, distinctly separated on 

 the latter, of the elytra rather small, deep and close-set, becoming 

 rapidly sparse and coarse near the base; tempora moderately re- 

 tracted, only feebly converging and then rounded to the base; 

 antennae slender, extending to apical fifth of the elytra, the third
