402 CASEY 



Body moderately stout and convex, shining, bright brassy or bronze, 

 the cinereous pubescence fine, rather short and sparse and moder- 

 ately conspicuous ; head moderately coarsely, deeply, evenly and 

 somewhat closely punctate, obtusely elevated at the middle of the 

 vertex, the epistoma broadly angulate with straight sides, the 

 orbital carinae sharply elevated ; prothorax (Q) rather small, 

 three-fifths wider than long, almost evenly trapezoidal, the sides 

 straight, excepting a very feeble swelling before the middle, the 

 apical angles very acute, narrowly prolonged and feebly everted, 

 the basal very acute, sharp and not everted, the thickened margin 

 even, narrowed only anteriorly ; ridges rather narrow and mod- 

 erately elevated, straight and parallel, obsolescent near the base, 

 the apex between them broadly sinuate, the depression moderate, 

 gradually evanescent toward the base ; punctures fine and rather 

 sparse, with a narrow distinct and subentire smooth line medially, 

 still rather fine but closer laterally ; elytra very obtusely rounded 

 behind, two-fifths wider than the prothorax and two and one-half 

 times as long, the sides strongly rounded at base ; surface with 

 broadly and moderately impressed lines suturally and finely but 

 rather closely punctured, with coarser punctures in the furrows, 

 larger and dense, shallow and asperulate laterally ; male unknown. 

 Length 9.7 mm.; width 4.^ mm. Texas (Alpine"), — H. F. 

 Wickham chalceus n. sp. 



8 — Head ( 9 ) very opaque and feebly impressed across the base of 



the vertex, where the punctures become very fine ; supra-orbital 

 carina fine but strong and acutely elevated at least in the female.. 9 



Head ( 9 ) ^^^^ notably more impressed or differently sculptured en- 

 tirely across the base of the vertex, more shining and more 

 coarsely sculptured 10 



9 — Pronotal ridges (Q) arcuate anteriorly, the inclosed depression 



more rounded. Body stout, deep black throughout, shining but 

 without metallic lustre, the pubescence extremely minute and 

 scarcely discernible ; head finely, rather closely and very evenly 

 punctured, slightly shining, the transverse depressed band behind 

 the vertex densely opaque and finely, more sparsely punctate, 

 each puncture with a short silvery hair, the occiput convex, 

 the epistoma very broadly and obtusely ogival ; prothorax (Q) 

 transverse, fully three-fifths wider than long, trapezoidal, with 

 very feebly arcuate sides becoming slightly sinuate near the apical 

 angles, which are very acute but not much produced, the thickened 

 margin unusually fine, thick near the base, where the angles are 

 right and not at all prominent ; ridges broadly convex, very feeble 

 and subobsolete behind the middle, interiorly oblique anteriorly, 

 moderately prominent at apex, the general surface alutaceous, 

 rather finely but deeply, not very sparsely punctate, more coarsely 

 and a little less sparsely so laterally, inipunctate along a fine line 

 adjoining the thickened edge except toward base; scutellum mod- 

 erate, acutely ogival, as long as wide ; elytra broad, oblong, one-
