424 Coleopterological Notices. 



sparsely punctate throughout, the punctures a little larger but not distinctly 

 denser laterally. Scutellum relatively very small, triangular, transverse, 

 wijb. narrow explanate polished margin. Elytra one-half longer than wide, 

 slightly wider and two and one-half times longer than the prothorax ; sides 

 feeLly arcuate, together gradually narrowed in apical two-fifths and acutely 

 rounded at apex ; disk without impressed striae but having distant rows of 

 very fine feeble sublineate punctures, which are widely and very unevenly 

 spaced ; intervals very minutely sparsely and feebly punctate. Abdomen more 

 polished, sparsely and extremely minutely punctate, almost glabrous. Legs 

 rather long, the tarsi moderate. 



Male. — Anterior tarsi strongly dilated, the first four joints forming an ellip- 

 tical patella ; intermediate feebly but distinctly dilated ; both pairs with pads 

 of dense spongy-pubescence beneath ; abdomen narrowly and feebly impressed 

 in the middle toward base. 



Length 6.5-6.7 mm. ; width 3.0-3.2 mm. 



Florida (Key West) ; Texas. 



A remarkably aberrant species of rather large size, easily recog- 

 nizable by its alutaceous, almost glabrous integuments and minute 

 feeble punctuation. The hind wings are excessively rudimentary 

 and relatively smaller than in any other species which I have been 

 able to dissect : they consist of a very slender, nearly opaque, semi- 

 membranous fillet, three or four times as long as wide and not quite 

 one-half as long as the prothorax. The elytra are almost completely 

 connate. 



2 B. dispar n. sp. — Elongate-elliptical, rather strongly, evenly convex, 

 black ; integuments smooth, very minutely evenly and strongly granulato- 

 reticulate, strongly alutaceous ; pubescence extremely sparse and short, cine- 

 reous, visible but very inconspicuous. Head feebly convex, rather finely 

 evenly and somewhat densely punctate, the punctures generally separated by 

 a little more than their own diameters ; epistoma deeply sinuate ; upper lobes 

 of eye moderate, separated by about five times their own width ; antenna? 

 nearly as in alutaceus. Prothorax rather elongate, about three-fifths wider 

 than long ; apex rather strongly, evenly emarginate in circular arc ; base 

 transverse, the sinuations distinct ; sides rather strongly convergent from 

 base to apex, strongly arcuate especially toward base ; disk widest before the 

 base, sparsely and very minutely punctate toward the middle, much more 

 coarsely and densely so toward the sides where the punctures are moderate in 

 size, deep and generally separated by their own diameters. Scutellum as in 

 alutaceus. Elytra from one-third to one-half longer than wide, just percepti- 

 bly wider, and about two and three-fourths times longer than the prothorax ; 

 sides broadly but distinctly arcuate, together gradually narrowed behind and 

 somewhat acutely rounded at apex ; disk with wide deeply impressed striae, the 

 stria? very coarsely punctured, the punctures circular, deeply perforate, not 

 much wider than the stria? and distant by from two to four times their own
