and third funicular joints short and equal, the outer joints very wide 

 and subcontinuous with the club in outline, the latter moderate, the 

 basal joint polished and sparsely setose, constituting about one-half 

 the mass, the remaining rings short and each abruptly and con- 

 spicuously less in transverse diameter than the preceding. Pro- 

 thorax one-third wider than long, the sides feebly convergent and 

 broadly arcuate very nearly to the apex, then more convergent and 

 broadly but distinctly constricted ; basal lobe rather narrow but 

 very prominent, the disk with an extremely narrow impunctate line, 

 the punctures rather small, about one-fourth as wide as the scutel- 

 lum and distinctly separated. Scutellum slightly transverse, the 

 posterior margin with two narrow deep notches. The elytra are 

 but slightly more than one-half longer than the prothorax, the striae 

 very fine but deep, the intervals broad, flat, slightly uneven in width, 

 finely closely and confusedly punctate throughout, and from five to 

 six or seven times as wide as the striae. Prosternum flat, separating 

 the coxae by a little less than their own width, nearly as in Onycho- 

 baris, but apparently not at all foveate anteriorly. Length 3.2-4.2 

 mm. ; width 1.6-2.2 mm. 



Texas and Colorado. Moderately abundant. 



2 Pycnol>aris squambtecta n. sp. — Robust, ovoid al, strongly con- 

 vex, the integuments black and polished throughout but covered densely with 

 long wide truncate and recumbent scales of a yellowish tint. Head minutely, 

 sparsely punctate and glabrous, the transverse groove very deep and abrupt, 

 the beak robust, densely punctate and squamose but narrowly impunctate and 

 subcarinate in the middle toward base, moderately, evenly arcuate and about 

 three-fourths as long as the prothorax ; antennae stout, densely squamose, 

 nearly as in pruinosa, the large basal joint of the club highly polished and 

 having widely scattered stiff setae. Prothorax fully one-third wider than long, 

 the sides rather strongly convergent and feebly arcuate from the base to apical 

 fifth, then broadly rounded but not prominent and broadly strongly constricted 

 to the apex, the latter not at all tubulate, broadly arcuate and two-fifths as 

 wide as the base ; basal lobe small but prominent ; disk with a narrow im- 

 punctate line, indistinct before the middle, the punctures small, not much 

 more than one-fourth as wide as the scutellum and separated by nearly one- 

 half of their own diameter. Scutellum trapezoidal, nearly twice as wide 

 posteriorly as at base, the posterior margin broadly, feebly bisinuate and the 

 surface behind broadly impressed, the angles acute. Elytra, at the large but 

 very feebly prominent humeri, only slightly wider than the prothorax, nearly 

 two-thirds longer than the latter, the apex broadly obtuse ; disk with fine 

 rather shallow striae, the intervals five or six times as wide as the striae, finely 

 but deeply, confusedly and rather sparsely punctate throughout, the scales
