eleventh small and veiy much shorter than the two preceding in 

 both sexes. Prothorax slightly narrower than the head, trans- 

 verse, the sides parallel and nearly straight ; apex broadly but 

 strongly arcuate; disk convex, slightly uneven, densel,y and 

 strongly- punctate. Elytra two-fifths longer than wide, twice as 

 wide as the prothorax ; sides parallel and broadly arcuate ; apex 

 semi-circulai'ly rounded ; femora well exposed and rounded at 

 base; disk not very coarsely but densely punctate, abruptly 

 nearly vertical at the flanks, the oblique impression from the 

 humeri feeble. Abdomen finely punctate, minutel}^ and very 

 densely pubescent. Length l.T-1.75 mm; width 0.75 ram. 



District of Columbia. The fourth ventral of the male is dis- 

 tinctly shorter than the third, broadly, evenl}^ rounded and un- 

 modified, the genital segment small, coriaceous and rounded ; the 

 fourth ventral of the female is fully as long as the third and is 

 evenly rounded behind, without noticeable modification of struc- 

 ture. 



2. P. sagiiiatiis u. sp. — Stout, convex, feebly shining, pale brownish- 

 testaceous, the abdomen piceous-black ; pronotum rufo-piceous; bead and hind 

 femora blackish; pubescence ver}' short, moderately dense, decumbent. Head 

 transverse, convex, somewhat closely punctate and conspicuously pubescent, 

 the eyes separated by slightly less than their own width; antennnc stout, 

 cylindriciil, scarcely at all incrassate, rather more than two-fifths as long as 

 the body, the basal joint as long as the next two, jjenultimate joints as long 

 as wide, the eleventh almost as long as the two preceding, obliiiuely pointed. 

 Prothorax transverse, subeqiial in width to the head, the sides very feebly con- 

 vergent from the subapical angles to the base; apex broadly arcuate, the base 

 less arcuate; disk convex, finely, moderately closely punctate, broadly and 

 extremely obsoletely impressed transversely near the base. Elytra oval, two- 

 fifths longer than wide, fully twice as wide as the prothorax, parallel and 

 broadly arcuate at the sides, very obtusely rounded at apex; disk with a feeble 

 uanow impression within the humeri not extending posteriorly, finely, 

 strongly and moderately closely punctate. Length 1.8-2.1 mm. ; width 0.9 mm. 



California (near Montere}^). 



A specimen from Arizona is much smaller, witli narrower and 

 more oblong el)'tra, which are more coarsely punctate and still 

 more polished, the punctures more impressed ; it probably repre- 

 sents a very closely allied species and is not included in the 

 above measurements. This species differs conspicuously from 

 brunnipennis in its more robust form, more shining surface, 

 longer antennae and numerous other characters.
