Coleopterological Notices, IV. 529 



punctures small, deep, circular, scarcely one-third as wide as the 

 seutellum and not quite in actual contact, although very dense. 

 The elytra are quite distinctly longer than wide, fully two-thirds 

 longer than the prothorax, and the sides behind the humeri are 

 decidedly convergent, the apex being somewhat narrowly semi- 

 circular ; the striiie are not very coarse or deep but abrupt, the 

 intervals flat, subequal in width, each rather more than twice as 

 wide as the grooves and not very coarsely punctured, the punctures 

 forming almost even single rows, but broadly confused on the fifth 

 throughout and on all toward base. The anterior coxce are remote 

 and the abdomen rather sparsely punctured. Length 2.C-3.S mm.; 

 width 1.2-l.C) mm. 



Texas, Kansas and Colorado. Easily distinguishable from the 

 species allied to densa, by the subserial arrangement of the inter- 

 stitial punctures and the more elongate form. 



8 Onycho1>aris argufa n. sp. — Oblong-oval, rather strongly convex, 

 shining, black throughout, the setse very small, slender and inconspicuous. 

 Head finely, rather sparsely punctate, the impression feeble, polished ; beak 

 rather stout, evenly cylindrical and arcuate throughout, densely, deeply, not 

 coarsely but rugosely punctate and quite distinctly shorter than the prothorax ; 

 antennae rather slender, inserted just behind the middle, the first funicular 

 joint fully as long as the next tliree, the second obconical, one-half longer ihan 

 wide, three to seven feebly transverse, the former nearly as long as wide. 

 Prothorax one-third wider than long, the sides parallel and nearly straight to 

 apical fourth, then rather abruptly, strongly rounded, thence convergent and 

 feebly sinuate to the apex ; base transverse, broadly bisinuate ; disk rather 

 convex, evenly, closely, not finely punctate, the punctures rounded, deep, 

 about two-fifths as wide as the seutellum and generally separated by about 

 one-half of their own diameters ; impunctate line obsolete. Seutellum rather 

 small. Eljjtra slightly wider than the prothorax and from one-half to three- 

 fifths longer, distinctly longer than wide, hemi-elliptioal, the humeri mode- 

 rately prominent ; strije not very coarse, somewhat shallow but abrupt, the 

 intervals slightly unequal, generally nearly twice as wide as the grooves, flat, 

 smooth, each with a single series of deep punctures which are moderately 

 large and rather distant, but becoming coarse and close-set toward base. 

 Abdomen rather finely but strongly punctate. Prosternum flat, the anterior 

 coxse rather large, separated by one-fourth more than their own width. Length 

 2.65-2.8 mm. ; width 1.2-1.3 mm. 



California (foot-hills of the southern sierras). Mr. 11. C. Fall. 



This species is not closely related to any other but should be 

 associated with audax ; it differs from ambigua and egena in its 

 black legs and in several other characters as stated in the table. In 

 general form it somewhat resembles pavperella.
