loo MEMOIRS ON THE COLEOPTERA 



sinus short and very feeble; striae rather fine but somewhat deeply 

 impressed, the scutellar slightly more than one-sixth the entire 

 length, the intervals convex internally, less so laterad, the puncture 

 slightly before apical fourth; basal joint of the hind tarsi very much 

 shorter than the fifth. Length (9) 9-7 mm.; width 3.7 mm. 

 Colorado (Buena Vista nearly 8000 ft. elevation), Wickham. 



aequabilis n. sp. 



Sides of the prothorax rounded throughout, though less so basally, the 

 apex distinctly sinuate and very evidently narrower than the base. 19 



19- Pronotal foveae short, linear, narrow and feeble though punctured. 

 Body oblong-oval, rather convex, shining, black, partially sub- 

 piceous beneath, the ambient pronotal bead, "hypomera, epipleura, 

 antennae, trophi and legs pale flavo-testaceous; head three-fifths 

 as wide as the prothorax, with moderate, very prominent eyes and 

 minute perforate foveae, the mandibles rather bright rufous, black 

 at tip, the antennae slender as usual; prothorax fully one-half wider 

 than long, the subtransverse base with the fine bead not definitely 

 interrupted medially; surface with the marginal gutter fine, barely 

 at all widening posteriorly and feeble, though punctulate, disap- 

 pearing near basal third, the transverse impressions somewhat 

 evident medially; punctuation evident basally almost throughout 

 the width; elytra not quite one-half longer than wide, slightly wider 

 than the prothorax, obtusely rounded at apex, with feebly arcuate 

 parallel sides, the sinus very feeble though evident, the striae fine 

 but rather deeply impressed, the scutellar rather long; intervals 

 notably convex throughout, polished, the puncture strong, near 

 apical fourth on the second stria. Length (cf ) 8.5 mm.; width 3.4 

 mm. British Columbia (locality not stated) lascivus n. sp. 



Pronotal foveae sublinear as usual but very broadly impressed, strongly 

 and closely punctured or rugiilose 20 



20 Basal angles of the prothorax slightly obtuse but scarcely at all 

 rounded, distinctly defined and only very slightly blunt at their 

 tips. Body small, moderately convex, rufo-piceous, paler beneath 

 the type probably somewhat immature, shining, the elytra only 

 faintly alutaceous even in the female; head three-fifths the thoracic 

 width, with prominent eyes, small perforate foveae and rather 

 slender antennae, the pale mandibles black at tip, the labrum black, 

 with fulvous edges; prothorax nearly one-half wider than long, the 

 base wider than the apex, with the bead interrupted at the middle; 

 surface with the reflexed edge only moderately fine apically, rela- 

 tively only slightly widening posteriorly, becoming punctulate and 

 disappearing behind basal third; basal punctuation wholly inter- 

 rupted medially, elsewhere very distinct to the sides; elytra oblong, 

 slightly less than one-half longer than wide, nearly a fifth wider than 

 the prothorax, very obtusely rounded at apex, the sides broadly 

 arcuate; striae rather fine, only feebly impressed, the scutellar rather 

 long; intervals not quite flat, the puncture near apical fourth; sinus 

 very feeble though evident; basal joint of the hind tarsi distinctly 

 shorter than the fifth. Length (9 ) 7-7 mm.; width 3.2 mm. Wis-
