262 MEMOIRS ON THE COLEOPTERA 



angles narrowly blunt and scarcely prominent; postero-lateral flat- 

 tening just traceable, vestigial; transverse impressions subobsolete; 

 stria very fine, nearly entire; inner fovea large, scarcely at all im- 

 pressed and very indefinite, the outer larger than usual, rounded, 

 impressed and attaining the base; elytra a third longer than wide, 

 rapidly obliquely ogival in about apical third, at the middle nearly 

 a fifth wider than the prothorax; humeral denticles extending slightly 

 beyond the thoracic angles; sides arcuate, narrowly but strongly 

 reflexed ; striae moderately fine, impunctate, the scutellar joining 

 the first; lateral series narrowly interrupted; intervals wide, flat; 

 hind tarsi long, both the middle and hind tibiae somewhat bent in 

 the male; abdominal apex in that sex with a close pair of punctures 

 at each side. Length (cf) 5.8 mm.; width 2.7 mm. Colorado. 

 Levette collection docilis n. sp. 



Body larger, with fewer or feeble punctures in the foveal region of the 

 pronotum 10 



10 Elytra fully three times as long as the prothorax; sides of the latter 

 parallel and nearly straight in basal half, rounding apically. Body 

 elongate, convex, dark red-brown and scarcely shining, the elytra 

 opaculate in the female; under surface shining, obscure rufous, the 

 legs pale rufous; head fully three-fifths as wide as the prothorax; 

 eyes moderately convex; strides subangularly foveiform; antennae 

 slender, ferruginous, extending barely behind the thoracic base; 

 prothorax fully one-half wider than long, the sides finely but sharply 

 reflexed; apex fully four-fifths as wide as the base, moderately sinu- 

 ate, with blunt angles; transverse impressions feeble, the stria finely 

 impressed, not quite entire; surface gradually feebly deplanate at 

 the sides, more broadly flattened behind; basal punctures rather 

 numerous, extending almost entirely across; foveae moderate, the 

 inner long and linear, the outer small and rounded; elytra one-half 

 longer than wide, obtusely ogivally rounded behind, a fourth wider 

 than the prothorax, the sides broadly and evenly arcuate; humeri 

 narrowly exposed at base; striae rather fine, feebly impressed, scarcely 

 punctulate, the scutellar long, joining the first, the lateral series of 

 punctures widely spaced but not interrupted; intervals feebly con- 

 vex; hind tarsi long, very slender; palpi very long, slender; mentum 

 tooth narrowly and feebly bilobed at tip. Length (9) 7-5 mm.; 

 width 3.3 mm. A single specimen from the Levette collection, 

 probably taken in Colorado brunnescens n. sp. 



Elytra distinctly less than three times as long as the prothorax, the latter 

 slightly wider at the middle than at base; the humeri narrowly but 

 always evidently exposed at base; body less elongate and evidently 

 more shining 1 1 



n Body stout, oblong-suboval, very shining (cf ), the elytra subopaque 

 (9), piceous above, slightly rufescent beneath, the epipleura and 

 legs pale rufous; head well developed, three-fifths as wide as the base 

 of the prothorax; eyes very moderately convex, the strides distinct, 

 oblique; antennae ferruginous, slender, long, in the male extending 

 far behind the thoracic base; prothorax distinctly less than one-half
