430 Coleopterological Notices. 



subrecumbent, grayish-brown in color, easily removable, not very dense but 

 distinct in perfect specimens. Head rather coarsely, moderately densely 

 punctate, the punctures a little smaller on the epistoma, the latter broadly, 

 strongly sinuate at apex ; upper lobes of eye rather large, circular, separated 

 by scarcely more than four times their own width, almost completely sur- 

 rounded by a fine deep groove ; antenna? rather robust, gradually and not 

 very strongly incrassate near the apex, third joint much shorter than the 

 next two, fourth much longer than the fifth. Prothorax about three-fifths 

 wider than long, slightly narrowed from base to apex ; sides evenly and rather 

 feebly arcuate throughout ; apex rather strongly, evenly emarginate in circular 

 arc ; base transverse, the lateral sinuations broad and distinct ; disk densely 

 punctate, the punctures moderate in size, deep, generally not tending to 

 coalesce longitudinally. Pcutellum rather small, polished, minutely, not 

 densely punctate. Elytra scarcely perceptibly wider than the prothorax and 

 nearly three times as long ; sides parallel and very feebly arcuate, more 

 noticeably so posteriorly, together somewhat acutely rounded behind, coarsely 

 striate, the stria? deeply impressed, coarsely deeply and rather approximately 

 punctate, the punctures circular, perforate and separated generally by about 

 their own diameters ; intervals from three to four times as wide as the punc- 

 tures, convex, rather coarsely deeply and somewhat sparsely punctured. Abdo- 

 men polished, rather coarsely and sparsely punctate, the pubescence short, fine, 

 very sparse and inconspicuous. Legs moderate, the tarsi unusually long. 



Male. — Anterior tarsi strongly dilated, the basal joint much narrower than 

 the second, equilatero-triangular, second and third transverse, equal in width ; 

 intermediate distinctly but much more feebly dilated, the first joint nearly as 

 wide as, and much longer than the second ; both pairs densely spongy-pubes- 

 cent beneath ; abdomen toward base narrowly and distinctly impressed, fifth 

 segment very feebly impressed. 



Length 6.4-7.5 mm. ; width 2.S-3.3 mm. 



Florida; Texas (Galveston and El Paso). 



There can he no doubt of the synonymy here proposed. The 

 species resembles dilatatus but differs in its somewhat narrower 

 form, rather more shining surface, coarser punctuation, sparser and 

 not longitudinally rugulose pronotal punctuation and longer nar- 

 rower prothorax, with less strongly arcuate sides. The specimens 

 collected by myself at the points in Texas nam'ed above do not differ 

 in the minutest detail from the unique Florida type of LeConte. 



This is a very widely diffused species, occurring over the entire 

 southern portion of the North American continent. 



9 B. dilatatus Lee:— Ann. Lye. Nat. Hist. N. Y., V, p. 146.— Oblong, 

 rather feebly convex, black, rather feebly shining ; pubescence moderate in 

 length, subrecumbent, somewhat stout, consisting of pale fiavo-cinereous and 

 dark piceous-brown hairs confusedly intermingled, somewhat dense and rather 

 conspicuous, persistent. Head rather small, feebly convex, rather coarsely,
