two preceding species, ttie sulcus deep, the punctures extremely minute 

 and sparse throughout, not more asperate near the sulcus except at 

 base; scutellum finely granulose, with a very fine and subentire median 

 carina; elytra very short and transverse, four-fifths wider than the 

 prothorax but scarcely as long as the latter, the punctures very minute 

 and sparse, the sutural impression at the scutellum distinct, the humeri 

 very oblique at base and widely exposed; abdomen parallel with 

 strongly, evenly arcuate sides, much narrower than the elytra, minutely 

 but not very sparsely punctulale, less minutely and more sparsely 

 toward base, the impressions decreasing rapidly in size and depth, the 

 third narrow and feeble, the first deep, strongly arcuate and coarsely, 

 closely punctate except at the sides, the second and third not more 

 coarsely punctate, impunctate along the basal margin; legs very slender 

 as usual. Length 2.4 mm.; width 0.53 mm. North Carolina (Tryon), — 

 shaken from pines gracilis n. sp. 



Form somewhat less slender, smaller in size, moderately convex, polished, 

 rufo-testaceous throughout, the abdomen clouded with blackish except 

 toward base, the head and elytra somewhat picescent, the latter flaves- 

 cent at base and narrowly at apex; antennae and legs pale; head large, 

 wider than long, parallel at the sides, the base very broadly arcuato- 

 truncate, the angles well rounded, the surface unimpressed, finely, 

 sparsely punctulate, the punctures larger and feebly asperate on the 

 occiput; antennae attaining the middle of the elytra, feebly incrassate 

 distally, the second and third joints much elongated, equal, the three 

 subapical wider than long; prothorax only very slightly longer than 

 wide, much narrower than the head, the sides prominent and angularly 

 rounded at apical two-fifths, thence strongly converging and straight 

 to the base, the sulcus and fine sparse punctulation as in gracilis; elytra 

 nearly as in that species but not quite so short or transverse, very 

 slightly longer than the prothorax and four-fifths wider, the sparse 

 punctulation slightly asperate, the post-scutellar impression very deep; 

 abdomen nearly as in gracilis, the first impression with only a few 

 coarse punctures toward the middle, the second and third feebler and 

 subimpunctate. Length 1.9 mm.; width 0.48 mm. Florida. 



parva n. sp. 



9 — Rather slender, convex, polished throughout, pale testaceous, the elytra 

 equally pale but subpiceous, paler at base and apex; abdomen less con- 

 vex than usual, polished, black, the first two segments pale flavate ex- 

 cept finely along their basal margins; antennae fuscous, pale at tip and 

 toward base, the legs pale throughout; pubescence wholly inconspicu- 

 ous; head well developed, broadly arcuato-truncate at base, subparallel 

 at the sides, the eyes rather large and prominent, the basal angles 

 rounded; punctures very minute and sparse, not noticeably larger or 

 asperate on the occiput; antennae long, rather stout, very feebly incras- 

 sate distally, attaining the apex of the elytra, the second and third joints 

 equal, the ninth as long as wide, the tenth very nearly so ; prothorax 

 distinctly elongate, much narrower than the head, the sides evenly 

 rounded anteriorly, thence strongly convergeqt to the base, becoming 

 evidently sinuate, the surface convex, the sulcus deep, the punctulation 

 very sparse and almost obsolete; scutellum sparsely, minutely granu-
