very feeble and the sutural notch broad; disk rather finely striate, 

 the intervals rather finely, moderately densely punctured. Proster- 

 nuni rather deeply but very narrowly sulcate, the coxa? large, pro- 

 minent, separated by scarcely more than one-fourth of their own 

 width. Length 8.2 mrn. ; width 13 mm. 



Texas (Columbus). Cab. LeConte. The unique type is the only 

 specimen which I have seen ; it is a female. This species is allied 

 to albescens, in spite of the great dissimilarity in form of the body; 

 the arrangement of the vestiture beneath is almost identical, but 

 lutescevs does not possess the denuded subapical spot of the elytra, 

 is much more coarsely punctate, and differs in so many characters 

 that there cannot, I think, be the least doubt of its distinctness. 



7 Barinus curticollis n. sp. — Rather narrowly oblong-oval, some- 

 what convex, polished, black, the legs dark rufo-piceous ; vestiture yellowish, 

 consisting, on the pronotum, of dense elongate-oval scales in lateral third, on 

 the elytra of nearly similar scales almost uniformly but not very densely dis- 

 tributed throughout, becoming finer and still sparser on the flanks, very sparse 

 throughout beneath, except on the met-episterna, where they are much denser, 

 also denser at the sides of the last three ventral segments. Head dull, finely, 

 sparsely punctate, the impression distinct ; beak short, thick, very strongly 

 arcuate, not as long as the prothorax, coarsely but sparsely punctate, some- 

 what squamulose above the eyes ; antenna slender, the basal joint of the fuui- 

 cle not quite as long as the remainder, club moderate. Prothorax short, two- 

 fifths wider than long, the sides parallel and straight to apical third, then 

 gradually rounded convergent and nearly straight to the apex, which is three- 

 fifths as wide as the base, the latter transverse, the median lobe broad and 

 feeble ; disk coarsely, rather sparsely punctate, the punctures round, deep, 

 perforate and isolated, with a narrow and irregular impunctate line. Scutel- 

 lum small, oval, tumid and glabrous. EUjtra slightly wider than the prothorax 

 and nearly two and one-half times as long, elongate hemi-elliptical, obtusely 

 rounded at apex, the humeri not laterally prominent ; disk deeply striate, the 

 intervals flat, from two to three times as wide as the grooves, coarsely, con- 

 fusedly but not very densely punctate. Abdomen finely, remotely punctate, 

 the basal segment coarsely and much more closely so. Anterior coxfe sepa- 

 rated by about one-half of their own width. Length 2.7-3.0 mm. ; width 

 1.0-1.2 mm. 



Missouri ; Louisiana. 



The description is drawn from the male, the abdomen having a 

 small deep elongate-oval impression near the base. This species is 

 allied to lutescens, but differs in its shorter prothorax, narrower 

 form, more slender, much sparser scales of the elytra and more 

 widely separated anterior coxtB.
