of the former distinct ; antennae slender, cylindrical, very feebly incrassate, 

 one-half as long as the body, all the joints elongate, the eleventh cylindrical 

 in basal half, thence conical to the pointed apex. Prothorax transverse, on«- 

 half wider than long, the sides broadly, almost evenly arcuate; apex four- 

 fifths as wide as the base ; disk impunctate but with small scattered punctures 

 near the basal margin, broadly, feebly convex, even, just visibly flattened 

 before the scutellum, narrowly explanate along the sides. Scutellum trian- 

 gular, polished, impunctate. Elytra ample, quadrate, at base as wide as the 

 prothorax, three-fourths longer ; sides nearly straight, feebly divergent from 

 base to apex ; disk with sparse, evenly distributed and very distinct punc- 

 tures. Abdomen fully as wide as the elytra but scarcely as long, sparsely and 

 extremely feebly punctnlate, the border wide, feebly delimited and more 

 densely punctate. Legs moderate. Length 2.2-3.3 mm. ; width 0.85-1.3 mm.

The male characters, other than palpal, are very feeble, the gene- 

 ral form of the body and length and structure of the antenna? being 

 nearly identical in the two sexes; the fourth palpal joint is very 

 strongly securiform, and the intermediate tibia? are broadlv and 

 just visibly sinuate within. The tibiae are very feebly and sparsely 

 spinulose. Ten specimens. 



P. pallidum n. sp. — Somewhat broad, feebly convex, shining though 

 feebly alutaceous, flavate ; abdomen black ; elytra feebly clouded with piceous 

 especially toward apex; head testaceous; antennae blackish in apical half; 

 pubescence short but abundant throughout. Head coarsely reticulate but 

 with only a few very fine and remote punctures, flattened above ; vertex 

 feebly, obliquely bistriate ; eyes well developed ; antennae very feebly incras- 

 sate, cylindrical, rather more than one-half as long as the body, all the joints 

 longer than wide, eleventh cylindrical in basal, and conical in apical, half. 

 Prothorax transverse, almost two-thirds wider than long ; sides rather strongly, 

 nearly evenly arcuate ; basal angles obtuse and rounded ; apex truncate, 

 three-fourihs as wide as the base ; disk feebly convex, narrowly explanate at 

 the sides, much more obliquely and broadly so toward base, almost perfectly 

 even, finely, densely punctate and rather coarsely reticulate, shining. Elytra 

 ample, scarcely as long as wide, at base subequal in width to the prothorax, 

 two-thirds ( ^ ) to three-fourths ( 9 ) longer than the latter ; sides nearly 

 straight, feebly divergent from base to apex ; disk flat, abruptly convex and 

 declivous at the sides, finely, very densely punctate but shining. Abdomen 

 shining, very feebly punctulate ; border wide, the dividing line very fine. 

 L«'gs moderate ; femora broad ; tibiae slender, finely and extremely sparsely 

 spinulose. Length 2.3-2.6 mm. ; width 0.8-1.0 mm.

Easily distinguishable from the others of Fauvel's " Section B," 

 by the pale coloration. The sexual differences in general form are
