and pubescent. Length (cf) 27.5 mm.; width 8.7 mm. Colorado, 

 Levette strenuus n. sp. 



Elytra as in macula sus in form but more elongate, rapidly cuneiform (cf ) 

 or nearly parallel (9), differing greatly in maculation, dark red- 

 brown to blackish in color, with relatively small separated punctures, 

 not denser though granuliform toward the humeri, clothed evenly 

 but not very densely with very short, decumbent, ashy hairs, with 

 small specks of blackish-brown tomentum sparsely intermingled, 

 these being simply a reduced form of the darker spots in maculosus 

 and carolinensis, as plainly shown occasionally by their oblique ar- 

 rangement; prothorax relatively larger than usual and with strong, 

 stout lateral spines, the central tubercle strong to almost obsolete. 

 Length (cf 9 ) 24.0-30.0 mm.; width 6.6-8.4 mm. Wisconsin, 

 Indiana and New York, [confusor Kirby] notatus Drury 



3 Body pure red-brown in color and of short, broad, parallel form, 

 somewhat as in oregonensis in outline but much smaller; elytra with 

 sculpture and maculation nearly as in maculosus, but with the 

 punctures in the larger patches of whitish uniform hairs, which 

 separate the spots of dense dark brown tomentum, much larger and 

 more isolated, the surface not so rugose except near the humeri; 

 antennae much shorter, three-fourths longer than the body (cf) 

 or but little longer than the latter (9). Length (cf 9 ) 14.2-20.0 

 mm.; width 4.2-6.8 mm. California (Siskiyou Co.).. .obtusus Csy. 



Body deep black in color, slightly shining but never having metallic 

 gloss, moderately elongate, stouter than in scutellatus, the elytra 

 strongly cuneiform (cf ) or nearly parallel (9 ), the punctures coarse 

 and everywhere very dense, forming transverse rugae, the vestiture 

 consisting of short decumbent and unevenly distributed dark brown 

 hairs, with small spots of dense white hairs intermingled; antennae 

 (cf ) rather less than two and one-half times as long as the body, 

 uniformly black, or ( 9 ) slightly longer than the body, black, with 

 white annuli at the bases of the joints. Length (cf 9 ) 15.0-24.0 

 mm.; width 4.6-7.8 mm. Rocky Mountains of Montana and Colo- 

 rado to northern Oregon monticola n. sp. 



Body deep black but generally with more or less distinct subaeneous 

 lustre, highly polished; outline narrower, slightly more elongate; 

 elytra less rapidly or strongly cuneiform, parallel in the female, 

 the punctures rather coarse but much shallower and less close-set 

 than in monticola and forming transverse rugulation only on parts 

 of the surface; antennae (cf ) barely twice as long as the body, or 

 ( 9 ) similar to the preceding but with the white basal annuli feebler. 

 Length (cf 9 ) 14.8-22.0 mm.; width 4.5-6.9 mm. Maine to Wis- 

 consin (Bayfield). [resutor Kirby; mutator Lee.]. . . .scutellatus Say 



4 Body more elongate than in any except certain females of carolinensis, 

 parallel in the female, the integuments nearly black, the elytra 

 nudely showing in certain small spots, mingled with the large dense 

 patches of white and ochreous-yellow tomentum, which are arranged 

 in broad ragged oblique lateral fasciae, somewhat as in titillator and 

 maculosus, the external outline gradually rounding and narrowing 

 behind and produced subacutely at the tips, the punctures not coarse,
