292 CUBCULKXNIDyF. [LeConte. 



Illinois to Kansas. Body oblong, rather elongate; head feebly puno'.u- 

 late, beak rather finely punctured, shor',, stout and much curved; frontal 

 constriction not deep. Prothorax wider than long, subquadrate, very 

 slightly narrowed from the base for three-fourths the length, then suddenly 

 narrowed to the tip, which is scarcely impressed at the sides; punctures 

 coarse, dense, smooth dorsal line narrow, sometimes obsolete. Elytra Avith 

 deep stripe, interspaces flat, strongly and confusedly punctured, forming 

 here and there transverse rugosities. Prosternum densely and coarsely 

 punctured, flattened and slightly concave in front, but not silicate; front 

 coxae moderately distant, antenme as usual. Length 4.5 mm. ; .18 inch. 



6. B. carimilata (Lee.), Pr. Ac. Nat. Sci. Phil. 1858, 79; ibid. 1868, 

 862, (Baridius). 



One specimen, Texas. Closely allied to the last, but the dorsal line of 

 the prothorax is more distinct, and the punctures of the elytra are irregular 

 only on the second and third interspaces, and form regular rows on the 

 others. The prosternum is longitudinally concave, and subsulcate, though 

 the limits of the groove are not well defined; the punctures are also less 

 dense. 



7. B. subsenea (Lee.), Pr. Ac. Nat. Sc. Phil. 1868, 361, (Baridiu^. 



Middle States. The color is brassy black, the beak more strongly punc- 

 tured, the prothorax not wider than long, coarsely and densely punctured, 

 with faint dorsal line. Elytra with deep striae, interspaces confusedly 

 punctured. Prosternum very coarsely punctured, broadly subsulcate. 

 Length 4.5 mm. ; .18 inch. 



8. B. tumescens (Lee.), Pr. Ac. Nat. Sc. Phil. 1868, (Baridius). 

 New York, Illinois, Louisiana, Texas. A brass} r species of oblong form, 



almost like B. transversa, with the prothorax coarsely punctured, and dor 

 sal line obsolete; the beak is finely punctured. Elytra with deep s'riae, in 

 terspaces narrow, each with a row of fine punctures, which are confused 

 upon the third. Prosternum coarsely punctured, broadly subsulcate. 

 Length 4-4.5 mm.; .16-.18 inch. 



9. B. nitida, n. sp. 



Oblong-oval, shining black \vilh a bronze tint. Head convex, scarcely 

 perceptibly punctulate; beak short, stout, curved, finely punctured, frontal 

 constriction well marked. Pro.horax not wider than long, gradually nar- 

 rowed from the base for two-thirds the length, then rounded and more sud- 

 denly narrowed to the tip, which is not at all impressed on the sides; disc- 

 very coarsely but sparsely punctured, without trace of smooth dorsal line. 

 Elytra scarcely wider than pro-horax, stria) deep, interspaces rather wide, 

 each with a single series of well impressed distant punctures. Prosternum 

 at the middle broadly but distinctly sulcate and sparsely punctured; flanks 

 broadly concave, so that the lateral edge is somewhat dis inct; front coxa? 

 moderately distant. Antennae as usual. Length 4.6 mm.; .18 inch. 



One specimen, Florida; Dr. Edward Palmer. Very distinct from all
