eleventh small and veiy much shorter than the two preceding in 

 both sexes. Prothorax slighth' narrower than the head, trans- 

 verse, the sides parallel and nearl3' straight ; apex broadly but 

 strongl}' arcuate; disk convex, slightly uneven, densel}^ and 

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

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

 semi-circularly rounded ; femora well exposed and rounded at 

 base; dislv not very coarsely but densely punctate, abruptl}' 

 nearly vertical at the flanks, the oblique impression from the 

 humeri feeble. Abdomen finely punctate, minutely and very 

 densely pubescent. Length 1.7-1.75 mm; width 0.75 mm. 



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. sa^iiiatus n. sp. — Stout, convex, feebly shining, pale brownish- 

 testaceous, the abdomen piceous-black ; prouotum rufo-piceous ; head and bind 

 femora blackish; pubescence A'ery short, moderately dense, decumbent. Head 

 transverse, convex, somewhat closely punctate and conspicuously pubescent, 

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

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

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

 as wide, the eleventh almost as long as the two ijreceding, obliquely pointed. 

 Prothorax transverse, subequal in Avidth 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 

 narrow impression within the humeri not extending posteriorlj', finely, 

 strongly and moderately closeh' punctate. Length 1 . 8-2. 1 mm . ; width 0. 9 mm. 



California (near Monterey). 



A specimen from Arizona is much smaller, witli narrower and 

 more oblong elytra, which are more coarsely punctate and still 

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

 sents a verv closel.y allied species and is not included in the 

 above measurements. This species differs conspicuously from 

 hrunnipennis in its more robust form, more shining surface, 

 longer antennte and numerous other characters.
