tennae infuscate distally, the legs pale; surf&ce finely, Icebly micro- 

 reticulate, the punctures not close-set, invisible except on the elytra 

 and abdomen, where they are asperulate; pubescence not very long or 

 close, pale; head with a deep rounded impression at the middle of the 

 vertex, somewhat narrowed behind the small subprominent eyes; an- 

 tennae nearly as in monticola, the third joint strongly constricted and 

 pedunculate at base; prothorax two-fifths wider than the bead and 

 tvvo-flfths wider than long, the sides distinctly converging and broadly 

 arcuate from base to apex; base strongly arcuate, the surface trans- 

 versely impressed before the middle of the base, the impression punc- 

 tate ; elytra slightly wider and a third longer than the prothorax, the 

 sides evidently diverging from the humeri, which are scarcely at all 

 exposed at base; abdomen barely as wide as the elytra, parallel, 

 slightly constricted at base. Length 1.6 mm.; width 0.6 mm. Texas 

 (Galveston) conrergens n. sp. 



9 — Form very stout, convex, hirsute, the antennae unusually stout. Shin- 



ing, black, the elytra castaneous; antennae black, rufe.scent toward 

 base, the legs pale; micro-reticulation almost obsolete throughout; 

 punctures fine, numerous, more visible on the elytra and abdomen; 

 pubescence long, abundant, erect and very conspicuous; bead well 

 developed, with an isolated rounded median impression on the vertex, 

 the sides converging behind the eyes; antennae evidently longer than 

 the head and prothorax, very stout, incrassate, the last joint very 

 ghort, obtusely pointed, much shorter than the two preceding com- 

 bined, the third strongly obconical and narrowed at base but not 

 abruptly constricted; prothorax about two-fifths wider than long and a 

 third wider than the head, parallel and nearly straight at the sides, 

 abruptly and arcuately narrowed only very near the apex, the basal 

 angles more distinct than usual in this section, the surface with two 

 small punctate impressions before the middle of the base arranged 

 transversely; elytra two-fifths widerand longer than the prothorax, the 

 humeri rather widely exposed at base; abdomen not quite as wide as 

 the elytra, narrowed posteriorly only near the tip. Length 1.7 mm.; 



width 0.68 mm. Virginia (Fort Monroe) hirsnta n. f-p. 



Form less obese and less hirsute, the antennae only moderately stout.... 10 



10 — Sides of the head evidently converging from the eyes to the basal 



angles. Moderately shining, black, the elytra and basal parts of the 

 abdomen slightly plceous; pubescence erect, rather abundant and dis- 

 tinct; head small, the vertex impressed, the impression extending nar- 

 rowly along the median line to the base of the occiput; antennae pale, 

 Infuscate near the apex; proihor ax rather large, transverse, the sides 

 feebly converging and rather strongly arcuate from base to apex, the 

 surface finely, not distinctly impressed transversely before the scutel- 

 lum; elytra with the humeri less exposed at base than in others of this 

 section, distinctly wider and longer than the prothorax; abdomen as 

 wide as the elytra. Length 1.4-1.45 mm.; width 0.5-0.58 mm. Rhode 



Island (Boston Neck) pilosa Csy. 



Sides of the head parallel or snbparallel behind the eyes 11
