 ifornia (Lake Tahoe) ............................ scenicum n. sp. 



Body slightly narrower and more convex, the elytra shorter and more 

 oval, deep black, shining, the elytra slightly brownish, each with a 

 subexternal pale spot near apical fourth, the apex and lateral margin 

 apically also pale; legs obscure rufous; head four-fifths as wide as 

 the prothorax, the eyes moderate; antennae scarcely three-fourths 

 as long as the elytra, blackish, the first three joints in great part 

 testaceous, the medial joints slightly more than twice as long as 

 wide; prothorax barely two-fifths wider than long; base much nar- 

 rower than the broad truncate apex and not quite three-fourths the 

 * maximum width; sides in about apical half parallel and moderately 

 arcuate, thence very oblique to the subparallel basal part, which is 

 nearly a fifth the total length; margins well reflexed; anterior im- 

 pression very feeble, the posterior coarsely sulciform and punctate, 

 abruptly interrupted at the middle; foveae deep, rather large, elon- 

 gate-suboval, adjacent to the long strong carina; elytra one-half 

 longer than wide, three-sevenths wider than the prothorax, gradu- 

 ally parabolic behind, the subparallel sides feebly arcuate and the 

 humeri 'moderately rounded; striae coarse but only very slightly 

 impressed, extending to the declivity internally, to the middle ex- 

 ternally, the punctures coarse, deep and well separated; foveae near 

 fourth and three-fifths. Length (9) 2.8-3.4 mm.; width 1.1-1.2 

 mm. Utah (Provo), Wickham. Three examples, .clemens n. sp. 



9 Prothorax large, about three-fourths as wide as the elytra. Surface 



polished, black, with feeble aeneous lustre, the elytra piceous, each 

 with a nubilous external spot near apical fourth and the posterior 

 part of the margin, barely attaining the suture, pale; under surface 

 black, the legs pale piceo-testaceous; head large, barely visibly nar- 

 rower than the prothorax, with prominent eyes, the sulci deep; 

 antennae scarcely three-fourths as long as the elytra, black, piceous 

 at base, the medial joints- fully twice as long as wide; prothorax 

 fully two-fifths wider than long, but little wider just before the middle 

 than at the broad truncate apex ; base four-fifths the maximum width ; 

 sides moderately reflexed, moderately rounded anteriorly, arcuately 

 converging posteriorly to the long subparallel basal part, which is 

 fully a fifth the total length; angles right, as usual; anterior impres- 

 sion feeble, the posterior also broad, feeble and medially interrupted, 

 nearly smooth; fovese elongate-oval, deep and somewhat distant 

 from the rather short but strong carina; elytra oblong, with arcuate 

 sides and subcircular apex, slightly more than one-half longer than 

 wide, the humeri somewhat broadly rounded though slightly ex- 

 posed at base; striae rather coarse but barely at all impressed, obso- 

 lete in apical fourth inwardly and half externally; punctures moder- 

 ately coarse and rather well separated; foveae at fourth and four- 

 sevenths. Length (9) 3.35 mm.; width 1.25 mm. Queen Char- 

 lotte Islands (Massett), Keen. One specimen, .peregrinum n. sp. 

 Prothorax relatively smaller, much less than three-fourths as wide as 

 the elytra ................................................. 10
