Coleopterological Notices, IV. 697 



Beak separated by a broad transverse impression ; head and basal parts of 

 the beak finely, remotely punctate, the remainder of the beak densely so ; 

 pronotum dull simplex 



P. robust mil n. sp. — Robust, cylindrical, the elytra perfectly parallel 

 and a little wider than the prothorax, polished, black and glabrous through- 

 out. Head rather finely but deeply, not densely punctate ; beak thick, finely 

 punctate, not separated from the head by a transverse impression, two-fifths as 

 long as the prothorax ; scrobes not extending to the eye, rectangular ; antennae 

 inserted at basal third, first funicular joint large, wider than long, rather 

 longer than the next two, second concealed partly within the apex of the first, 

 apparently shorter than the third, two to five coarctate, forming a thick com- 

 pressed mass, the club scarcely at all wider or thicker and forming nearly a 

 prolongation of the funicle. Prothorax about as long as wide, broadly rounded 

 on the sides, constricted behind the apex, the latter three-fourths as wide as 

 the base ; punctures coarse, deep, perforate, separated by about one-half of 

 their own diameters, with a polished impunctate central spot. Scutellum 

 rounded, slightly tumid. Elytra one-half longer than wide ; striae deeply 

 impressed, coarsely deeply and closely punctate ; intervals two to three times 

 as wide as the strial punctures, convex. Under surface coarsely, closely punc- 

 tate, the abdomen more sparsely so, and more finely, except at base. Length 

 3.7 mm. ; width 1.3 mm. 



Texas (Austin). 



The single specimen is of undetermined sex. 



P. simplex n. sp.— ^Cylindrical, moderately stout, black, glabrous, the 

 pronotum subalutaceous. Mead very finely, sparsely punctate ; beak finely, 

 closely punctate except toward base, separated from the head by a rather deep 

 wide transverse impression, which is very sparsely punctate and minutely, 

 obsoletely foveolate, thick, parallel, as long as the head, not one-half as long 

 as the prothorax ; scrobes deep, rectangular, not attaining the eye by a very 

 noticeable distance ; antennae inserted near basal third, nearly as in robustwn, 

 but with the joints much less transverse. Prothorax nearly as long as wide, 

 feebly constricted behind the apex, the latter broadly arcuate and nearly four- 

 fifths as wide as the base ; sides feebly arcuate ; punctures coarse, deep, sepa- 

 rated by much less than their own widths, without median impunctate area. 

 Elytra parallel, barely three-fifths longer than wide, nearly twice as long as 

 the prothorax and slightly wider ; striae deeply impressed, coarsely, deeply 

 but not very closely punctate ; intervals convex, finely, sparsely, subseriately 

 punctate, twice as wide as the strial punctures. Under surface hot coarsely 

 but strongly, rather sparsely punctate throughout. Length 2.5 mm. ; width 

 0.95 mm. 



Nebraska. 



Allied to robustum but differing in its smaller size, dull and not 

 polished pronotum, relatively longer elytra with narrower inter- 

 vals, different structure and sculpture of the beak and antennae, and 

 in many other features.
