closely punctate, with a fine impressed median line in posterior half. 

 Length (c?) 6.3 mm.; width 3.75 mm. Colorado (Leadville), 



Wickham canterius n. sp. 



Elytra without a closed common crescentiform figure; outline more 

 elongate 13 



13 Form elongate-oval, more produced and pointed posteriorly than 

 anteriorly, black throughout, the antenna? black with a feeble 

 piceous tinge; head rather coarsely, very deeply and densely punc- 

 tate, with rather coarse pubescence which is slightly variegated; 

 prothorax distinctly less than half as long as its basal width, the 

 strongly converging sides somewhat swollen and arcuate basally, 

 compressed anteriorly, the punctures minute, deep and very dense, 

 the pubescence longer than usual, very coarse, black, much variegated 

 by aggregated lines and patches of fulvous, the scutellum with 

 coarse, dense, almost wholly black hairs; elytra one-half longer than 

 wide, parallel, the sides feebly arcuate, becoming gradually rounded 

 and converging in apical two-fifths, the apex rather narrowly para- 

 bolic and somewhat produced; surface extremely densely opaque, 

 the hairs coarse, black, interspersed plentifully with fulvous, with 

 a small transverse solid transverse spot of yellow-cinereous hairs 

 at the middle of the suture and a small one at each side in nearly 

 the same line, at about lateral third; alternate intervals with denser, 

 almost wholly black hairs; abdomen strongly and closely but some- 

 what finely asperate, the metasternum more coarsely, very densely 

 and rugosely punctate, the hairs very short but rather coarse, well 

 separated. Length 6.3 mm.; width 3.5 mm. Idaho (Cceur d'Alene), 

 Wickham centralis n. sp. 



Form nearly similar but less produced and more evenly rounded behind, 

 smaller in size, almost similar in coloration and general nature of 

 the variegated vestiture; head small, convex, very densely punctate; 

 prothorax nearly as in centralis but less compressed apically and with 

 less minute and not quite so dense sculpture, the vestiture nearly 

 similar; elytra not more than a third longer than wide, parallel and 

 feebly arcuate at the sides, the latter evenly and more broadly 

 rounding behind from well behind the middle; surface less densely 

 punctate and slightly shining, the vestiture rather shorter, coarse, 

 black, with interspersed fulvous hairs, the alternate intervals with 

 shorter black condensations, the fulvous hairs tending to form 

 several posteriorly arcuate transverse common bands, the solid 

 yellowish spot at the middle of the suture transversely rhombiform; 

 abdomen similarly but less densely asperate. Length 5.3 mm.; 

 width 3.0 mm. Colorado. (Leavenworth Valley, 10000 to nooo 

 feet elevation), Wickham explicatus n. sp.

Elytral striae very feeble, discontinuous, sometimes much interrupted. . 18 



15 Form stout, oblong-parallel or very nearly parallel, very broadly 

 obtuse behind 16 



Form parallel and oblong-elongate, obtusely rounded behind, much
