punctate, having a wide deeply-impressed groove which becomes obsolete at 

 anterior third ; episterna not attaining the apex by nearly one-half their own 

 length, clearly limited within throughout ; hypomera flat, strongly reticulate, 

 alntaceous, finely and sparsely punctate, the inner polished marginal bead 

 moderate in width. Abdomen finely reticulate, shining ; punctures moderate, 

 sparse ; pubescence short, setose and sparse, the last segment flat, with a 

 densely pubescent median area. Length 1.7-1.9 mm. 



California (Mendocino, Santa Clara and Los Angeles Cos.). 



The pubescence is rather short, sparse, pale fulvo-cinereous in 

 color, robust, acutely pointed and subrecumbent. This is a very 

 common species throughout western California. 



JL. Iliontanus Lee. — Bull. U. S. Geol. Surv., V, 1879, p. 514. — Almost 

 evenly oval, strongly rounded at apex, a little less than twice as long as wide, 

 black throughout, subalutaceous ; pubescence very short, subrecumbent, very 

 sparse, cinereous, apparently easily abraded, not conspicuous. Head with fine 

 longitudinal rugse, the concave intervals more minutely and feebly rugulose, 

 and with small distant punctures ; lateral carina fine but strong. Prothorax 

 more- than twice as wide as long ; sides very feebly arcuate ; apex about two- 

 thirds as wide as the base, the basal lobe strong, with the apex sinuous, fitting 

 the base of the scutellum ; surface finely granulose laterally, more polished 

 in the middle, rather finely and sparsely punctate ; median groove very fine, 

 short. Scutellum one-half longer than wide ; sides and base very distinctly 

 arcuate, the surface very minutely and sparsely punctate. Elytra rather less 

 than four times as long as the prothorax, and, at basal third, about one-fifth 

 wider ; sides very distinctly, evenly arcuate and coarctate with the sides of 

 the prothorax ; surface finely, sparsely punctate ; punctures round, shallow, 

 not impressed, separated by at least three times their own widths. Presternum 

 polished, very finely and sparsely punctate, slightly more coarsely and closely 

 so anteriorly ; median groove narrow, very deep posteriorly, becoming more 

 feeble anteriorly and obsolete at apical fourth ; episterna distinctly limited 

 within throughout, not attaining the apex by about one-third of their own 

 length ; hypomera flat, not impressed at the inner angle, finely, strongly 

 reticulate, alutaceous, minutely, sparsely and not distinctly punctate ; inner 

 bead strong. Abdomen very finely, densely reticulate throughout, minutely 

 and very sparsely punctate ; fifth segment with a very small impression just 

 behind the ajjical margin, the pubescence of the central area coarse, short and 

 not very dense. Length 2.0 mm. 



Colorado (La Yeta). Mr. Schwarz. Cab. LeConte. 



The sculpture of the elytra is peculiar, although merely an inten- 

 sification of the normal sculpture in this section of the genus. Each 

 puncture is surrounded by a series of six flat reticulations, the series 

 contiguous externalh', the outer bounding lines being hexagonal. 

 This is a remarkably distinct species.
