MEMOIRS ON THE COLEOPTERA 



and in the legs as a rule. My collection contains representatives 

 of the common eastern brunneipennis and blanchardi, minimus 

 Fall, from Colorado, a species represented by two examples from 

 Helena, Mont., which I think represent horni Wick., described from 

 Wyoming, and another allied closely to the latter as follows: 



Hetaerius loripes n. sp. Body oblong, stout, thick, with the upper sur- 

 face feebly convex, rufo-ferruginous in color throughout; head concave, 

 finely, densely rugulose and opaque, with a few short hairs; prothorax 

 two-fifths wider than long, the converging straight grooves, from near 

 the sides of the base, entire and very coarse, the middle section smooth 

 and subglabrous medially, punctulate and with short stout hairs laterally 

 and basally, the lateral lobes divided by a deep transverse sulcus at 

 basal third, the basal section convex, pubescent, extending laterally 

 somewhat beyond the base of the anterior portion, which is flat, densely 

 punctate, expanded anteriorly and bristling with very short coarse hairs; 

 elytra moderately abbreviated, slightly inflated near the base, having a 

 posteriorly evanescent inner, and a short outer, subhumeral stria, a sub- 

 entire first and third, and an intermediate fine dorsal stria, the latter 

 abbreviated at apical third; the first and third dorsals are coarse and 

 have their external sides much swollen and very densely clothed with 

 short erect squamiform hairs, which are plumose about their edges, the 

 outer side of the humeral is also cariniform but more finely; intermediate 

 surfaces shining, subglabrous, punctate and with short coarse squamae 

 posteriorly; flanks vertical, in part flat, shining and sparsely punctate; 

 propygidium moderately punctate, each puncture bearing a very short 

 thick hair; pygidium almost smooth; prosternum elevated, flat, with 

 two parallel striae, at apex tumid and with its apical truncate surface, 

 below the mandibles, concave and opaque; legs long, the tibiae broad 

 and more or less flattened, the anterior subparallel in apical two-thirds, 

 rapidly narrowed basally, the posterior obtusely angulate externally, the 

 angle at the middle of the length; all the hairs and scales of the body and 

 legs are pale fulvous-yellow in color. Length 2.4 mm.; width 1.8 mm. 

 California (Tulare Co.). One example received about fifteen years ago, 

 without data concerning the host and with no record of the collector. 



This species is smaller than morsus Lee., but belongs to the same 

 section of the genus. In morsus, according to Horn, the elytra 

 have striae indicated by finely elevated lines, the first dorsal entire, 

 the second extending three-fourths and the third nearly two-thirds 

 the length; this striation is quite different from that of loripes and, 

 according to the figure given by Dr. Horn, the hind tibiae in morsus 

 are not so expanded or externally angulate as they are here. From 

 tristriatus Horn, which has nearly similar elytral striation, the 

 present species may be known by the legs, these being normal and 

 not long or with flattened tibiae in tristriatus; the head in loripes is
