6 Pseildobaris lllgubris n. sp. — Oval, moderately robust, strongly 

 convex, black throughout and polished, the setse sliort, sparse but distinct, 

 not condensed at the base of the third interval and without longer scattered 

 squaraules. Head finely, distinctly, the beak rather coarsely, punctured, 

 more densely in the male, strongly arcuate and quite distinctly longer than 

 the prothorax in both sexes, the antennae moderate, with the second funicular 

 joint distinctly longer than the third. Prothorax nearly one-third wider than 

 long, the sides subparallel or very feebly convergent and nearly straight to 

 apical third, then strongly rounded and convergent to the apex, the latter 

 broad, truncate, three-fifths as wide as the base and brietly tubulate ; base 

 transverse, the median lobe small but prominent, broadly rounded at apex ; 

 disk with a narrow ill-defined impunctate line which does not attain the apex, 

 the punctures rather fine, scarcely one-fourth as wide as the scutellum and 

 dense, somewhat unevenly distributed and very narrowly separated. Elytra 

 hemi-elliptical, distinctly longer than wide, not quite twice as long as the 

 prothorax and a little wider than the latter ; disk with moderately fine but 

 very deep abrupt grooves, the intervals flat, subequal, about twice as wide as 

 the grooves, each with a single series of somewhat small, shallow, moderately 

 remote punctures. Prosternum deeply, abruptly sulcate, the coxae rather 

 small and separated by a little more than their own width. Length 3.0-3.3 

 mm. ; width 1.3-1.6 mm. 



New Mexico (Albuquerque). 



A rather small species, resembling nigrina in outline, but with 

 smaller, feebler interstitial punctures and devoid of scattered squam- 

 ules ; from angusta it is at once distinguishable by its much more 

 broadly oval form. The smallest and narrowest specimen before 

 me is a female, the largest a male. Four specimens. 



I have united with this species a still siiialler specimen from 

 Te.xas, which differs in its slightly coarser and very dense pronotal 

 punctures and scarcely larger but much deeper interstitial punc- 

 tures; it possibly represents a distinct species.

Oval, subcylindrically convex, rather polished, deep black through- 

 out. The beak is slender, evenly, rather strongly arcuate and equal 

 in thickness from base to apex, just visibly longer than the protho- 

 rax in the male, but nearly one-third longer than that part in the 

 female, the antennae normal, with the second funicular joint about 

 one-half longer than the third. Prothorax very nearly as long as 

 wide, broadly constricted near the apex, the sides nearly parallel in 

 basal two-thirds, the disk rather coarsely, densely punctate, the 

 punctures two-fifths as wide as the scutellum and separated by less
