broadly toward the humeri, legs and basal parts of the antennae, more 

 or less pale testaceous; punctures of the head and pronotum rounded, 

 umbilicate, coarse and very close-set, those of the elytra not quite so 

 coarse and less dense, of the abdomen fine, sparse and asperulate, the 

 ground sculpture finely and feebly reticulate in subtransverse lines, of 

 the elytra finely and obsoletely subreticulate, elsewhere smooth; vesti- 

 ture fine, rather sparse and wholly inconspicuous, each abdominal seg- 

 ment with a transverse series of four coarse erect black setae ; head 

 wider than long, fully as wide as the prothorax, convex, unimpressed; 

 antennae distinctly incrassate distally, extending rather beyond the 

 elytral apex; prothorax obtrapezoidal, only very slightly wider than 

 long, the sides prominently rounded at apical third, thence distinctly 

 converging and sinuate to the base, the surface convex, unimprested in 

 either sex; elytra each with a black seta near the middle of the base, 

 about one-half wider and but slightly longer than the prothorax, the 

 the humeri widely exposed; abdomen parallel, with the sides evidently 

 and evenly arcuate, distinctly wider at the middle than the elytra in the 

 male, much narrower than the elytra and with the sides straighter in the 

 female; sixth ventral of the male with arcuately converging sides, the 

 obtuse apex with a small and broadly, evenly rounded sinus about 

 five or six times as wide as deep; female distinctly more slender than 

 the male throughout the body. Length 1.65-1.8 mm.; width 0.4-0.45 

 mm. Rhode Island, New York and North'Carolina CAshevllle) to Iowa.

Form nearly similar to venustula, polished, rufo-piceous, the prothorax 

 somewhat paler, the abdomen black, the first two segments, elytral base 

 and humeri, legs and basal parts of the antennae more or less pale fla- 

 vate; femora piceous, paler toward base; antennae infuscate distally; 

 punctures of the head and pronotum less coarse, more impressed and 

 much less clo.se-set than in venustula, those of the pronotum not umbil- 

 icate, the elytra not at all reticulate, having rather strong and moderately 

 sparse punctures, somewhat smaller than those of the anterior parts, 

 the abdomen finely, transversely reticulate, finely and sparsely punctu- 

 late; pubescence inconspicuous; prothorax similar to that of venus- 

 titla but somewhat narrower than the head, especially in the male; 

 elytra three- fifths wider and nearly a third longer than the prothorax, 

 the humeri widely exposed; abdomen parallel, with feebly and evenly 

 arcuate sides, fully as wide as the elytra in the male and nearly as wide 

 in the female; sixth ventral of the male nearly as in the preceding, the 

 broadly and circularly rounded sinus about six times as wide as deep; 

 female but slightly more slender than ttie male, with the sixth ventral 

 rather strongly and evenly rounded at tip. Length 1.8 mm.; width 

 0.48 mm. Texas (El Paso) to Utah (Provo.) montana n. sp. 



3 — Body rather slender, polished, similar in sculpture, punctuation and 

 vestiture to venustula, the coloration similarly disposed throughout but 

 paler in every part, perhaps from immaturity; prothorax fully as long 

 as wide and as wide as the head, the sides angulate, more obliquely, 

 arcuately rounded anteriorly from apical two-fifths to the neck, other- 

 wise as in venustula, the median line narrowly and obsoletely impressed 

 behind the middle, the impression not attaining the base ; elytra strongly
