apical third. Length (cf ) 4.0 mm.; width 1.33 mm. Utah (Provo) 



YVickham fidele n. sp. 



45 Form stout, oblong, moderately convex, very small in size and shin- 

 ing throughout, piceous-black, the elytra piceous, nubilously pale 

 at base, along the sides basally and more distinctly at apex, also with 

 a small marginal pale spot near the apex, connected along the 

 margin with the apical pale area; epipleura pallescent, the legs piceo- 

 rufous; head moderate, the head, prothorax and elytra increasing 

 regularly in width, the sulci rather deep, parallel; eyes only moder- 

 ately prominent; antennae rather short and thick, fuscous, paler 

 basally, the medial joints nearly twice as long as wide; prothorax 

 broad, fully one-half wider than long, widest near apical third, the 

 sides there strongly rounded, oblique and nearly straight in more 

 than basal half, the margins moderately reflexed; angles sharp, only 

 slightly obtuse; base broad and subtruncate; anterior impression 

 very feeble, the basal distinct, nearly smooth; foveae rather deep, 

 linear, almost as long as the distinct carina; elytra short, oblong, 

 only a third longer than wide and a third wider than the prothorax, 

 wider posteriorly than at base, obtusely subcircular at apex, the 

 sides broadly arcuate, gradually rounding at the humeri, which are 

 but narrowly exposed at base; striae slightly abbreviated, rather 

 coarse and impressed suturally, but fine and wholly unimpressed 

 laterally; punctures fine externally, strong suturally; foveae near 

 two and four sevenths. Length (cf) 2.7 mm.; width 1.15 mm.

novellum n. sp. 



46 Species very small, resembling vile, but with more transverse pro- 

 thorax; basal transverse impression of the latter having a series of 

 very coarse punctures 47 



Species not so minute, the posterior pronotal impression without an 

 evident series of punctures 48 



47 Body rather narrowly suboval, convex, polished, black throughout; 

 legs black, the coxae piceous; head fully four-fifths as wide as the 

 prothorax and wider than an elytron, the eyes notably prominent; 

 sulci parallel and rather deep; antennae not very stout, rather short, 

 piceous-black, the medial joints barely twice as long as wide; pro- 

 thorax about one-half wider than long, narrower at base than at 

 apex, widest at anterior two-fifths, where the sides are strongly and 

 somewhat subprominently rounded, very strongly, arcuately con- 

 verging thence posteriorly, becoming subparallel and nearly straight 

 in basal fifth; margins very moderately reflexed; anterior impression 

 obsolete, the posterior distinct except at the middle; stria very fine, 

 not entire; foveae small, oval, smooth, very deep and adjoining the 

 carina, which is strong and a fifth the entire length; elytra more 

 than one-half longer than wide, about one-half wider than the pro- 

 thorax, parallel, oblong-oval, with broadly arcuate sides; stria? rather 

 coarse, feebly impressed, strongly and rather closely punctate, ab- 

 breviated only on the declivity; seventh stria fine, unimpressed, ex-
