not quite as long as the body, the third joint one-third longer than the fourth. 

 Prothoiux nearly as long as wide, the base and apex subequal, truncate ; sides 

 parallel, evenly and strongly arcuate ; disk even, finely feebly and very 

 remotely punctate. Scutellum small, impressed, scarcely darker. Elytralong, 

 fully two and one-half times as long as wide; humeri slightly prominent; 

 sides parallel and straight ; apices individually evenly and strongly rounded ; 

 suture margined ; disk coarsely, sparsely punctate, the punctures less coarse 

 toward apex. Legs slender, moderately densely clothed with rather short 

 even pubescence ; hind femora slightly darker at tip ; tarsi slender, first joint 

 of the posterior as long as the entire remainder, second rather more than twice 

 as long as wide. Length 9.5 mm. ; width 2.3 mm. 



Texas (El Paso). 



The male serving as the type has the prosternum before the coxaB 

 scarcely depressed but coarsely ver}' densely punctate and more 

 densely pubescent, as in many species of Stenosphenus. 'i'his 

 sexual mark exists also in B. sutxiralis, from which the present 

 species ditfers in its more elongate form, shorter and coarser 

 pubescence, which is pale and not black, less punctate head and 

 more elongate legs. 



OXOPLIJS Lee. 



The differences between this genus and Crossidius are exceed- 

 ingly slight, and it is probable that the tw^o will have to be merged at 

 no distant day ; the type of ornamentation is identical in each. The 

 following species differs from any of those hitherto described in the 

 development of the fine elytral ridges, which are distinct very nearly 

 to the apex. 



O. COCCineilS n. sp. — Moderately stout, convex, feebly shining, bright 

 scarlet, the head, antennae, entire under surface between the anterior and 

 posterior coxae, apical and basal beads of the prothorax, scutellum, basal 

 margin of the elytra, and a common narrow sutural dash in apical half black ; 

 pubescence pale, extremely short, sparse and inconspicuous, rather short 

 sparse and blackish on the legs. Head coarsely densely and unevenly punc- 

 tate ; antennae slender, about one-fourth longer than the body, the appendage 

 of the eleventh joint scarcely more than one-third of the total length, with its 

 apex abruptly concave internally and arcuately pointed. Prothorax one-half 

 wider than long, the lateral tubercles acute and strong; basal bead very 

 prominent at the sides ; disk very coarsely, closely punctate, with five large 

 concolorous tubercles which are scarcely less punctate than the remainder of 

 the surface. Scutellum finely, closely punctate. Elytra at base distinctly 

 wider than the prothorax, fully four times as long ; sides distinctly conver- 

 gent from the rather prominent humeri to the apex, which is truncate, the 

 sutural angles acute and slightly prolonged ; disk very coarsely, closely punc-
