and very minutely grannlato-reticulate. The beak is somewhat 

 stout, strongly but not very densely punctate, except at the sides 

 toward base where it becomes somewhat rugulose, strongly, evenly 

 arcuate, barely as long as the prothorax, the antennae normal, with 

 the second funicular joint but slightly longer than the third, the 

 club rather large, elongate, ovoidal, pointed and moderately abrupt. 

 Prothorax two-fifths wider than long, the sides parallel and feebly 

 arcuate to apical fourth, then strongly rounded and convergent and 

 feebly sinuate to the apex, the base broadly bisinuate, the disk with a 

 broad fusiform impunctate line, the punctures rather small, scarcely 

 more than one-fourth as wide as the scutellum laterally, abrupt and 

 perforate, rather sparse and separated by much more than their own 

 widths, becoming a little smaller, more feeble and still sparser toward 

 the median line. Elytra parabolic, but slightly longer than wide, 

 one-half longer and just visibly wider than the prothorax, not very 

 coarsely but deeply and abruptly striate, the intervals flat, subequal, 

 more than twice as wide as the stride, each with a single series of 

 somew^hat small but distinct, subtransverse and very remote punc- 

 tures, each bearing an extremely short but rather robust seta not 

 projecting beyond its limits. The prosternum very widely separates 

 the small anterior coxse, and has, near the apex, a small feeble par- 

 allel-sided impression, ending anteriorly in two small punctiform 

 foveae. Length 3.4 mm.; width 1.6 mm. 



New Mexico. The type in the cabinet of LeConte is, as far as 

 known, still unique. 



18 Onychobaris molesta n. sp. — Oval, strongly convex, shining, 

 black with a piceous tinge, the head, beak and legs rufous ; setae very minute 

 and inconspicuous. Head obsoletely and sparsely punctured even anteriorly, 

 the feeble impunctate impression with a small deep median fovea ; beak 

 strongly, evenly arcuate, moderately stout, fully as long as the prothorax, 

 minutely, rather sparsely punctured, the punctures larger and rather close 

 at the sides ; antennae normal, moderate in length. Pi-ot/iorax moderate in size, 

 not at all inflated, scarcely more than one-fourth wider than long ; sides feebly 

 convergent and slightly arcuate from the base, more convergent near the apex, 

 the latter constricted and broadly but briefly subtubulate ; base broadly bi- 

 sinuate, the median lobe rounded and more prominent than the sides ; disk 

 somewhat convex. Scutellum transverse. Elytra one-fifth longer than wide, 

 about two-thirds longer than the prothorax, and, at the small but distinctly 

 prominent humeri, a little wider than the latter; sides convergent, the apex 

 parabolic ; disk with coarse deep and abrupt grooves, the intervals flat, equal, 

 scarcely one-half wider than the grooves, each witii a single series of very
