204 MEMOIRS ON THE COLEOPTERA 



subprominent; surface very smooth and polished, with rather fine 

 but deep entire stria and finely reflexed side margins from apex to 

 base, the foveae elongate, lineiform but broadly and very deeply 

 impressed and finely, densely punctulate, the surface between them 

 and the sides narrow and strongly convex; elytra oblong-oval, 

 two-fifths longer than wide, a third wider than the prothorax, with 

 parallel arcuate sides and obtuse apex, the sinus short but rather deep ; 

 surface opaculate, pale tawny yellow, with a large common blackish 

 cloud, the striae fine, the scutellar long, the intervals flat, bearing 

 some short hairs laterally and apically, the punctulation however not 

 distinct; abdomen with some scattered fine punctulation toward 

 base of each segment except the last; basal joint of the hind tarsi 

 much shorter than the fifth. Length (9 ) 9.2-10.2 mm.; width 3.7- 

 4.0 mm. Utah (Provo), YVickham. Four examples. 



nivalis Horn 



Form much narrower, rather more convex, small in size, black throughout 

 above and beneath, the legs black, the elytra and epipleura uniform 

 pale red-brown; head nearly as in the preceding but smaller; maxillary 

 palpi black, with pallid apex; antenna? rather short and stout, black, 

 with pale basal joint; prothorax two-fifths wider than long, nearly 

 as in nivalis throughout, except that the base is rectilinearly trans- 

 verse throughout, the sides posteriorly more sinuate, the basal 

 angles accurately right and sharply marked but not prominent and 

 the extremely deep basal fovese shorter and more rugose; elytra 

 nearly one-half longer than wide and a fourth wider than the pro- 

 thorax, obtuse at apex, parallel, the sides but slightly arcuate; sinus 

 very feeble though evident; surface with a few short hairs along the 

 sides and at apex, the striae not very fine, rather deep, the scutellar 

 long, the intervals feebly convex, alternating very slightly in width, 

 the discal puncture at apical third; metasternum finely but distinctly, 

 rather closely punctured laterally; abdomen without evident punctu- 

 lation, except the usual post-c:>xal; hind tarsi with the basal joint 

 but little shorter than the fifth. Length (cf ) 8.0 mm.; width 3.0 mm. 

 California parvulus n. sp. 



4 Body larger, oblong-suboval, strongly convex and very shining 

 throughout in both sexes, black above and beneath, the sides of the 

 pronotum, rather broadly and sharply, and all but a broad sutural 

 feebly defined black region on the elytra attaining the base, pale 

 testaceous, the epipleura, entire legs and antennae testaceous; head 

 with a nubilous red spot, smooth, impunctate, with prominent eyes 

 and slender antennae, the foveae rather coarse, very deep, somewhat 

 irregular; mandibles bright rufous, black apically; prothorax not 

 quite one-half wider than the head, not quite one-half wider than 

 long, the sides broadly rounded anteriorly, rather strongly converging 

 and feebly sinuate basally, the angles somewhat more than right, 

 very sharply marked and minutely subprominent; apex broadly and 

 moderately sinuate, somewhat wider than the base; surface with 

 very minute punctulation apically and stronger punctures through- 

 out basally, finer and sparser medially but rather coarse and dense 

 in the foveae, which are less abruptly linear and not so deep as in
