Baring 513 



Barinus Csy. 



The species of this genus are moderately numerous and were 

 included under Barilepton by LeConte, but the general habitus of 

 the body is very different, lacking the narrow and subcylindric 

 outline of that genus, as well as some of its more distinctive struc- 

 tural characters. The two following species are hitherto unde- 

 scribed : 



Barinus ferruginosus n. sp. — Oblong and moderately convex, black 

 throughout, the integuments shining where exposed, the upper surface 

 densely clothed with large, oblong, ferruginous scales, abruptly glabrous 

 in a large oval median area on the pronotum; under surface and femora 

 with very minute and slender, sparse squamules, more distinct at the 

 outer sides of the anterior coxaj and becoming dense whitish scales on 

 the met-episterna and sides of the last three ventral segments; beak in 

 the female thick, smooth, finely punctulate, strongly arcuate basally, 

 straighter apically, and distinctly shorter than the prothorax, the 

 antennae at the middle subinferiorly; prothorax nearly one-half wider 

 than long, the sides parallel and arcuate, gradually more converging 

 before the middle, the feebly constricted apex fully three-fifths as wide 

 as the base; punctures rather coarse, separated by less than their dia- 

 meters, the median smooth line distinct and entire; scutellum rounded, 

 nude; elytra two-fifths longer than wide, about as wide as the prothorax 

 and two and one-half times as long, the sides parallel, gradually rounding 

 in apical two-fifths to the narrowly obtuse apex, the humeral prominences 

 feeble: striae indicated by clefts in the dense vestiture; abdomen finely, 

 sparsely punctate and polished, more strongly and closely punctate on 

 the first segment; anterior coxae separated by less than half their width. 

 Length (9) 3-0 mm.; width 1.2 mm. Missouri (St. Louis), — Schuster. 



Related to curticolUs but broader, more oblong, with still more 

 transverse and laterally more rounded prothorax and denser and 

 more ferruginous vestiture of the upper surface; it seems to be 

 related also to Ititescens Lee. 



Barinus debilis n. sp.— Oblong, parallel, rather convex and shining, 

 black, the legs piceo-rufous; elongate scales of the upper surface whitish 

 and rather sparse, more distinct, though not denser toward the sides of 

 the pronotum, narrowly and loosely confused on the strial intervals, 

 the squamulation beneath as in the preceding species and curticollis; 

 beak in the male thick, strongly, evenly arcuate, strongly punctate but 

 shining, only about three-fourths as long as the prothorax, the antennae 

 slightly beyond the middle, the funide and club together about as long 

 as the beak; prothorax a fourth wider than long, the sides nearly straight, 

 subparallel or very feebly diverging, rapidly rounding and oblique in 

 apical third, the feebly constricted apex three-fifths as wide as the base; 

 punctures rather coarse, separated by nearly their diameters, smaller
