of cinereous and fulvous ; integuments polished. Head coarsely, very densely, 

 evenly cribrate ; supra-orbital carinse almost completely obsolete. Prothorax 

 much more than twice as wide as long ; sides feebly, evenly arcuate ; apex 

 nearly three-fourths as wide as the base, the latter sinuate at each side of the 

 wide and prominent median lobe ; surface polished, not at all reticulate at the 

 sides, coarsely, deeply, very densely punctate ; hairs very robust, not growing 

 from the punctures but each attached at the margin of a puncture ; median 

 groove fine, distinct, slightly nearer the base than the apex. Scutellum 

 moderate, very slightly longwr than wide, pointed, densely punctate ; sides 

 and base strongly arcviate. Elytra about three and one-half times as long as 

 tlie prothorax and scarcely one-fifth wider ; sides coarctate with those of the 

 prothorax; surface polished, very coarsely and densely punctate; punctures 

 very deep, perforate and separated by less than one-half their own diameters. 

 Prosternum polished, coarsely punctate, the punctures separated by about 

 twice their own widths ; median groove long and strong ; episterna not dis- 

 tinctly defined anteriorly ; hyponiera polished throughout, coarsely, very 

 densely punctate, deeply impressed near the inner obtuse angle ; inner mar- 

 ginal bead distinct ; inner posterior edge forming the margin of the crural exca- 

 vation abrupt, acute and cariniform. Abdomen polished throughout, coarsely, 

 very densely and deeply punctate, the punctures polygonally crowded ; fifth 

 segment convex, not impressed, more densely pubescent in the middle ; pubes- 

 cence throughout rather long, fine, and pale silvery-cinereous. Length 1.8 mm. 



Pennsylvania — Cab. LeConte. Texas. 



A well-marked species of wide distribution, var3^ing considerably 

 in size, but not otherwise to any noticeable extent. 



L.. liebulosiis Lee. — Bull. U. S. Geol. Surv., V, p. 515. — Oblong-oval, 

 strongly rounded behind ; sides nearly straight id the middle ; black, polished 

 throughout ; pubescence rather long, subrecumbent, very robust, somewhat 

 dense, confusedly mottled cinereous and fulvous. Hiud extremely coarsely 

 and densely cribrate, tlie punctures very deep and polygonally crowded ; 

 supra-orbital ridges entirely obsolete. Prothorax much more than twice as 

 wide as long ; sides distinctly although feebly arcuate ; apex nearly three- 

 fourths as wide as the base, the latter sinuate on each side of the median lobe 

 which is moderate ; median groove very short, feeble ; surface extremely 

 densely, coarsely cribrate, the punctures polygonally crowded, and only two- 

 thirds as wide as those of the elytra. Scutellum moderate, very slightly 

 longer than wide, densely, coarsely cribrate, slightly convex ; sides and base 

 arcuate. Elytra but very slightly wider than the prothorax, extremely densely 

 cribrate, the punctures very coarse and deep, polygonally crowded, the lines 

 of separation being but one-fourth or one-fifth as wide as the punctures. Pro- 

 sternum coarsely but much more sparsely punctate, the median groove very 

 wide and deeply excavated, extending almost to the apical margin ; episterna 

 not at all defined toward apex internally, polished, impunctate ; hypomera 

 extremely deeply impressed or excavated near the inner obtuse angle, polished, 

 very coarsely, deeply and densely punctate ; inner marginal bead very strong
