cens; prothorax shorter and broader, two-thirds or more wider than 

 long, the sides, basal angles and impressions similar; elytra shorter, 

 scarcely more than two-fifths longer than wide, scarcely two-fifths 

 wider than the prothorax, more rapidly and subobtusely rounded 

 behind, the sides feebly arcuate; striation and foveae nearly similar; 

 five striae are easily discernible, the sutural stronger than the others. 

 Length 2.3-2.5 mm.; width 0.75-0.85 mm. Texas (Austin). 



hyalinus n. sp. 



17 Body oblong-suboval, broad, rather convex, shining; elytra pale 

 yellowish-brown, with the faintest possible transverse cloud behind 

 the middle, even this sometimes wanting; under surface piceous- 

 black, the legs and epipleura flavate; head three-fourths as wide as 

 the prothorax, half as wide as the elytral base, the sulci deep, widely 

 separated; eyes moderate but rather prominent, the tempora behind 

 them a fourth as long and evenly continuing their outward curve to 

 the neck; antennae fuscous, with flavate basal joint, barely as long 

 as the elytra; prothorax scarcely one-half wider than long, widest 

 at anterior two-fifths, the sides arcuate, oblique and nearly straight 

 posteriorly to the reflexed, obtuse and not apically prominent angles; 

 margins finely reflexed anteriorly, gradually broadly so posteriorly; 

 subbasal impression deep, moderately arcuate; elytra broad, scarcely 

 one-half longer than wide, two-thirds wider than the prothorax, 

 rapidly ogival in posterior two-fifths, the sides arcuate; five striae 

 are distinctly observable, increasing in depth inwardly; anterior 

 fovea at basal third. Length 2.65-2.7 mm.; width i.o-i.i mm. 

 New York (near the city) temporalis n. sp. 



Body suboval but less broad, shining, the head black; prothorax piceous, 

 the elytra pale brownish-flavate, with a very large central black 

 area, not attaining the sides, somewhat as in proximus; under sur- 

 face black, the legs and epipleura flavate; head nearly four-fifths as 

 wide as the prothorax, much more than half as wide as the elytral 

 base, the sulci deep, with convex intermediate surface, moderately 

 separated; eyes and tempora as in the preceding; antennae rather 

 longer than the elytra, fuscous, paler basally; prothorax two-fifths 

 wider than long, the rounded sides becoming oblique and straight 

 posteriorly, very feebly sinuate near the reflexed obtuse angles; 

 anterior impression evident, the subbasal deep, broadly arcuate, 

 the median stria connecting them deep and conspicuous; elytra 

 scarcely one-half longer than wide, two-thirds wider than the pro- 

 thorax, ogival in apical two-fifths, slightly wider behind the middle 

 than at base; sides arcuate, the humeri rather broadly rounded; 

 pedicel less than one-half the basal width; first and second striae dis- 

 tinct, the third feeble, the others obsolete; anterior fovea rather 

 before basal third. Length 2.6-2.75 mm.; width 0.9-1.0 mm. 

 Mississippi (Vicksburg) nubifer n. sp. 



1 8 Form not broadly suboval, rather convex, shining, the head black- 

 ish, the pronotum rufo-piceous, the elytra pale rufo-testaceous, 

 feebly clouded with piceous, except broadly toward base and some- 

 times at apex; under surface rufo-piceous, the legs flavate; head well 

 developed, fully three-fourths as wide as the prothorax and sub-
