LeConte.] APPENDIX. 423 



scales, which form white lateral vittae on the prothorax, and cliscoidal lines 

 on the elytra. Black, beak stout, curved, punctured at base, smooth 

 towards the tip. Prothorax more caarsely but less densely punctured, 

 almost cribrate, sides nearly parallel, rounded behind and obliquely nar- 

 rowed in front of the middle ; dorsal line distinct. Elytra suddenly and more 

 distinctly wider than the prothorax at base. ; strise narrow, deep, im- 

 punctured, interspaces more strongly punctured, white scales denser 

 on the second interval for four-fifths the length ; upon the fourth there is a 

 short basal line, then a long line extending from one-fourth of the length 

 to three quarters ; on the sixth a basal line extending to one-fourth of the 

 length. Beneath strongly punctured, thinly clothed with white scales, 

 metathoracic episterna and spots on third, fourth and fifth ventral seg- 

 ments densely scaly ; the scales are also gradually more dense on the 

 sides of the first and second ventral segments. Length 3.8 mm. ; .15 inch. 

 Enterprise, Florida; one specimen, Mr. E. A. Schwarz. 



4. Barilepton quadricolle, n. sp. 



Very narrow, linear, black, clothed with elongate small whitish scales, 

 beak less stout, punctured at base, smooth at tip. Prothorax as long as 

 wide, sides parallel behind, suddenly rounded and narrowed in front of 

 the middle ; strongly and rather densely punctured ; dorsal line smooth, 

 distinct, scales more dense at the sides. Elytra suddenly a little wider 

 than the base of the prothorax ; striae narrow, deep, impunctured, inter- 

 spaces finely punctured, beneath strongly punctured, thinly clothed with 

 small whitish scales. Length 3.2 mm. ; .13 inch. 



Nebraska, one specimen ; given me by Mr. Ulke, I confounded this 

 species with B. filiforme, which it resembles in the form of the prothorax, 

 but differs by the stronger punctuation and by the elytra being distinctly 

 wider than the prothorax just behind the base ; the scales are also whiter 

 and larger, and the elytral striae are deeper. 



These four species may therefore be distinguished as follows : 



Body very narrow, filiform, elytra not wider at base 

 than the prothorax, which is densely but not deeply' 

 punctured, scales very small, gray, denser at the 

 sides of prothorax and elytra 1. filiforme. 



Body very naxTow, prothorax strongly and densely 

 punctured, suddenly narrowed in front, scales 

 of elytra oval, whitish, not very small 4. quadricolle. 



Body linear, but less narrow, prothorax densely, less 

 coarsely punctured ; elytra a little wider than the 

 prothorax at base, scales very small, rounded, yellow- 

 gray 2. lineare. 



Body as in lineare, but the elytra are more conspicuously 

 wider near the base, and the scales are elongate, 

 white, and form stripes ; prothorax more coarsely 

 punctured 3. cribricoUe.
