punctipennis n. sp. 

 Thoracic umbo not at all impressed or only very finely and feebly at the 



posterior end 24 



24 Elytra shorter, not more than three-fourths longer than wide. 

 Bright brick-red in color, the entire under surface of the hind body 

 and anterior coxa? deep black; legs red, the knees black, the two 

 anterior tibiae at base and apex, the posterior wholly, black, the 

 tarsi black but with reddish-pubescent soles; cinereous pubescence 

 of the upper surface feeble and inconspicuous, of the under moderately 

 dense and somewhat fusco-cinereous; erect hairs long, numerous 

 and black; head sparsely punctate; antennae black, annulate, nearly 

 as long as the body (cf), the scape red, black at apex; prothorax 

 one-half wider than long, the lateraljprominences strong, rounded, the 

 umbo rather narrow, with feebly arcuate sides, strongly and abruptly 

 elevated, sparsely and not very coarsely punctate; elytra strongly 

 but not closely punctate, the spots distinct, the post-humeral oc- 

 casionally wanting. Length (c? 9 ) 11.0-12.8 mm.; width 4.0-4.8 

 mm. New Mexico (Fort Wingate), Shufeldt. . .atrisetosus n. sp. 

 Elytra longer, about twice as long as wide, more obscure red, the cinereous 

 hairs of the upper surface more numerous, giving a moderate bloom, 

 the erect hairs rather short, in great part cinereous; under surface 

 black, densely clothed with rather coarse olivaceo-cinereous pubes- 

 cence; legs black, the femora red, the two anterior tibiae also some- 

 times in great part rufous; head less sparsely punctate; antennae 

 nearly similar, except that the scape is black, rufescent medially 

 above; prothorax a little more transverse, the strong lateral prom- 

 inences more narrowly rounded, the umbo a little broader, with more 

 arcuate sides and coarser and more numerous punctures; basal 

 margin black throughout the width; elytra coarsely, rather closely 

 punctate, more closely medially except toward the suture, the four 

 spots well developed. Length (cf) 13.0 mm.; width 4.8 mm. 



Colorado femoratus Lee. 



A Similar but still more slender in form and with the punctures less 

 coarse and not so close-set, the erect hairs a little longer, cinereous; 

 antennae similar but notably shorter, much shorter than the body; 

 prothorax nearly similar, the base blackish only at the sides; legs 

 entirely black, all the femora red; under surface similar. Length 

 (cf 9 ) 11.8-12.3 mm.; width 4.2-4.5 mm. Iowa (Keokuk). 



amnicola n. subsp. 



B Smaller, still more slender and not quite so convex, the punctures 

 less coarse than in femoratus and decidedly sparser, the erect hairs 

 much longer, fuscous and cinereous; antennae as in amnicola; 

 prothorax similar, except that the lateral prominences are not so 

 strong and much more broadly rounded, the umbo similarly very 

 strongly and abruptly elevated but limited behind by a more 

 distinct transverse sulcus; base feebly nigrescent at the sides; 

 pubescence of the under surface finer and shorter than in the two
