 anthracinus Sturm, i. litt. 



I have applied this name to a series which, in general, very rea- 

 sonably satisfies the description above cited. The specimens are 

 from Montana, Wyoming, Colorado and New Mexico, being con- 

 fined to the more elevated regions of the Rocky Mountains. The 

 species is black throughout, rather robust, oblong, moderately con- 

 vex, distinctly shining and with the sides nearly parallel. The 

 stria? of the elytra are exceedingly feebly impressed, very finely, 

 rather closety punctured and, in some of the specimens, almost con- 

 fused toward base with the somewhat unusually coarse punctures 

 of the flat intervals. The anterior tarsi of the male are strongly 

 dilated, the intermediate very distinctly, although less strongly so, 

 and the wings are well developed, being fully as long as the elytra. 

 The punctures of the pronotum are rather coarse, decidedly elon- 

 gate, closely crowded but not greatly coaleseent laterally, and 

 usually very slightly sparser toward the middle in the female, and 

 more decidedly so in the male. The latter sex resembles the female in 

 form but is rather smaller. Length 5.0-5.5 mm. ; width 2.1-2.G mm. 



24 B. lepidus n. sp. — Narrow, elongate-oval, moderately convex, gradu- 

 ally narrowed behind from near the middle of the elytra, black, moderately 

 shining or subalutaceons ; pubescence moderate in length, fine, rather sparse, 

 dark piceo-cinereous and not conspicuous. Head fully one-half wider than 

 long, finely, rather densely punctate ; upper lobe of eyes moderate, rounded ; 

 antennae rather slender, the last tbree joints somewhat abruptly wider, third 

 one-half longer than the second and a little longer than the fourth, eleventh 

 somewhat pointed and a little narrower than the tenth. Prothorax about two- 

 thirds wider than long, the sides very feebly convergent from base to apex, 

 feebly arcuate ant riorly, broadly and extremely feebly sinuate in the basal 

 half; base transverse, the lateral sinuations strong; basal angles right, not 

 in the least rounded ; apex broadly emarginate in circular arc ; disk finely 

 punctate, the punctures equal in size throughout, separated by about twice 

 their diameters toward the middle and rather denser laterally, but without 

 any marked tendency to coalesce. Scutellum moderate, ogival, rather dis- 

 tinctly wider than long. Elytra about two and one-half times as long as the 

 prothorax, subequal in width to the latter, the sides parallel toward base and 

 scarcely visibly arcuate ; disk very finely striate, the strise feebly impressed, 

 not becoming stronger laterally, very finely punctate throughout the width, 

 the punctures generally separated by two or three times their own diameters ; 

 intervals nearly flat, very finely, rather sparsely and unusually feebly punc- 

 tate. Abdomen polished, very finely and sj>arsely punctate, the pubescence 

 short, cinereous, distinct but not conspicuous. Leys well developed ; tarsi 

 slender.
