L.. perpolitus n. sp. — Almost evenly elliptical, ratlier pointed behind, 

 almost twice as long as wide, black tlirougliout, liighly polished. Head 

 strongly, longitudinally rugose, the intervals finely, sparsely pubescent and 

 punctate ; cariniform upper margins of the eye pronounced, the small dorsal 

 fovea immediately before the eye very deep. Prothorax much more than twice 

 as wide as long ; sides nearly straight ; apex two-thirds as wide as the base, 

 tlie latter strongly sinuate at each side of the median lobe which is well 

 developed ; surface polished, excessively obsoletely reticulate in the middle, 

 strongly so and slightly alutaceous at the sides ; median groove short, feeble, 

 broadly impressed ; disk very minutely, sparsely punctate and pubescent. 

 Scutellum nearly one-half longer than wide, minutely, sparsely punctate; 

 sides and base arcuate. Elytra not quite four times as long as the prothorax ; 

 sides very evenly and distinctly arcuate and coarctate with the sides of the 

 prothorax, the humeri not in the least prominent ; surface very highly 

 polished ; punctures very minute and feebly impressed, separated by from 

 four to five times their own widths ; pubescence very fine, short and sparse, 

 silvery-cinereous throughout, not conspicuous. Prosternum finely, very 

 sparsely punctate ; median impressed groove nearly equal in width throughout, 

 obsolete at apical fifth or sixth ; episterna distinctly limited within through- 

 out, almost attaining the apex ; hypomera transversely, feebly convex, finely 

 reticulate, not impressed, very finely, feebly and sparsely punctate through- 

 out, the polished bead forming the inner margin very strong. Abdomen finely 

 reticulate laterally toward base, not at all reticulate and polished at apex, 

 finely, sparsely punctate, a small pubescent area near the apex of the fifth 

 segment densely and deeply punctate, not impressed but with the apical edge 

 reflexed. Length 1.7-1.9 mm. 



Texas (Austin); New Mexico ("Albuquerque). Mr. Wickliam. 

 A very distinct species in its extremely minute, sparse punctua- 

 tion and pubescence, and highly polished upper surface. 



L,. afer Lee. — Proc. Acad. Nat. Sci. Phila., VII, p. 117. — Oval, about two- 

 thirds longer than wide, widest near the middle, rather acutely pointed behind, 

 black, polished ; pubescence coarse, rather long, subrecumbent, moderately 

 dense, in great part fulvous. Head with fine, rather feeble, longitudinal rugae ; 

 intervals finely punctate ; pubescence abundant, suberect. Prothorax about 

 two and one-half times as wide as long ; sides nearly straight ; apex two-thirds 

 as wide as the base, the latter deeply sinuate at each side of the moderate 

 median lobe ; surface highly polished throughout, without trace of granulation 

 or reticulation even near the sides, rather coarsely and sparsely punctate. 

 Scutellum one-half longer than wide. Elijtra at the humeri rather abruptly 

 but slightly wider than the prothorax, about four times as long as the latter, 

 and one-fourth wider ; sides evenly arcuate ; surface rather coarsely and 

 deeply punctate, the punctures impressed and separated by nearly their owu 

 widths. Prosternum somewhat coarsely and sparsely punctate, the median 

 groove rather feeble, vanishing at apical fourth ; episterna small, deeply, 

 coarsely punctate, not clearly limited within anteriorly, and coming very far
