AMERICAN COMPONENTS OF THE TENTYRIIN^ 415 



near base and apex, the basal angles acute and somewhat everted, 

 the apical obtuse and not prominent but not rounded, the apex 

 distinctly and evenly sinuate; surface coarsely but s'parsely punc- 

 tate toward the middle, with a smooth line obliterated anteriorly, 

 very coarsely, more closely so laterally but more finely toward the 

 feeble basal impression near each side and also less coarsely, 

 densely along the sides ; elytra fully three times as long as the pro- 

 thorax and nearly a third wider, rather rapidly ogival in about apical 

 third, the sides arcuate, scarcely more strongly so toward the humeri, 

 which are obtusely subangulate, rounded and slightly exposed 

 basally, the callus long and distinct; surface without impressed 

 lines, the punctures very coarse, rather sparse and confused 

 throughout, smaller and closer near the sides ; abdomen shining, 

 coarsely, rather densely punctate medially, more sparsely on the 

 first segment. Length 11. 0-12.0 mm.; width 4.75-5.1 mm. 

 Locality not recorded, but probably Utah, — H. F. Wickham. 



perpolita n. sp. 



4 — Elytra with distinctly though feebly impressed lines of aggregated 

 coarser punctures. Body elongate-oval, convex, polished, pale 

 brownish-testaceous in color throughout, with very small, sparse 

 and decumbent fulvous hairs ; head coarsely, sparsely punctate, 

 more closely toward the eyes and anteriorly, the occiput, concealed 

 by the prothorax, finely, closely punctured as usual, the epistoma 

 broadly and obtusely triangular ; prothorax not very transverse, 

 about a third wider than long, the apex nearly four-fifths as wide 

 as the base, evenly though very feebly sinuate, the angles slightly 

 obtuse, not rounded but not at all prominent, the sides very feebly 

 arcuate, becoming straight or subsinuate near apex and base, the 

 basal angles right, not prominent, the surface with moderate and 

 very sparse impressed punctures, becoming coarse and as a rule 

 closer laterally and but little less coarse and very close near the 

 sides; scutellum ogival, about as long as wide ; elytra with rather 

 strongly, evenly arcuate sides, gradually acutely ogival posteriorly, 

 strongly impressed along the suture toward tip, coarsely, sparsely 

 and confusedly punctured, the punctures but little coarser or closer 

 but more uneven and with some fine punctures on the interstices 

 laterally, the series throughout rather distinct ; abdomen very finely, 

 closely punctvn'ed and dull medially and with more evident pubes- 

 cence throughout than on the upper surface. Length 10.3 mm. ; 

 width 4.2-4.65 mm. ((^ and 9)' Texas (near El Paso). 



subseriata n. sp. 



Elytra with broadly and feebly impressed lines, in which coarser punc- 

 tures are aggregated even more closely and more conspicuously 

 than in subseriata. Body much stouter aud larger in size, black- 

 ish-castaneous, shining, strongly convex, broadly ovoidal ; head 

 coarsely and sparsely punctured, less coarsely and more closely 

 toward the eyes and front but not at all densely, the epistomal lobe 

 moderate, ogivally rounded ; prothorax somewhat less than one-
