422 APPENDIX. [LeConte. 



usual ; fifth ventral segment as long as the third and fourth united. Antennae 

 with the first joint of the funicle elongate ; second not longer than the third. 

 Length 4.3 mm. ; .17 inch. 



Colorado ; one specimen, Mr. B. D. Smith. This remarkable species does 

 not seem related to any other in our fauna by form or sculpture.

3. Zygobaris ? convexus, n. sp. 



Less robust, but more convex, shining black (sparsely clothed with white 

 scales?) Beak slender, slightly curved, as long as head and prothorax, 

 punctured -towards the base, smooth towards the tip ; basal transverse im- 

 pression distinct. Head sparsely punctulate. Prothorax not wider than 

 long, much rounded on the sides, narrowed and constricted in front, deeply 

 and coarsely punctured, with a smooth, dorsal line, and an indistinct 

 smooth space each side half way towards the sides. Elytra suddenly wider 

 at base than the prothorax ; humeri obtusely rounded, sides converging be- 

 hind ; strife deep, irapunctured, interspaces a little wider than the strise, 

 flat, each with a single row of very small punctures, which probably bore 

 white scales. Beneath strongly punctured, thinly pubescent, prosternum 

 flat, not transversely impressed nor foveate; front coxae not very widely 

 separated. Funicle of antennai stout ; first joint elongate ; second not longer 

 than third. Length 2.4 mm.; .10 inch. 



Enterprise, Florida ; one specimen, Mr E. A. Schwarz. The scales have 

 been removed by abrasion, and only a few remain near the base of the ely- 

 tra, and the sides and base of the prothorax. The apical constriction of the 

 prothorax does not continue across the prosternum as in tlie other species, 

 and as in all Geiitrinus known to me, but disappears in the apical margin, 

 thus leaving the front part of the prosternum flat. This should probably 

 be considered a generic difference, but I am unwilling to separate it with- 

 out having better preserved specimens for study. The claws seem to be 

 very small, but hardly connate at base.

2. Barilepton lineare, n. sp. 



Elongate, black, clothed with small, dirt-colored scales, which on the 

 elytra are scarcely wider than long, obovate, and broadly subtruncate. 

 Beak stouter than B. fiUforme, and more coarsely punctured at base. Pro- 

 thorax densely and deeply, though not very coarsely punctured, with a 

 narrow, smooth, dorsal line. Elytra a little wider than the prothorax at 

 the base, striate and punctured as m B. filiforme. Length 3.8 mm.; .15 

 inch. 



Sumter County, Florida ; one specimen, Messrs. Hubbard and Schwarz. 

 Differs from B. filiforme by the larger size, the punctuation of the protho- 

 rax and the form of the scales of the elytra ; the elytra are also evidently, 

 though but slightly wider than the base of the prothorax, and the sides of 

 the latter are suddenly rounded in front of the middle. 



3. Barilepton cribricolle, n. sp. 



Of the same siz3 and form as B. I'neare, but clothed with elongate, white
