Abdomen very finely and sparsely punctate. 



Elytral punctures coarse, denser, the pubescence extremely dense and the 



lustre dull lutrocllillllS 



Elytral punctures finer, more sparse, the surface much more shining. 



Elytral pubescence very short, even ; abdominal punctures visible through- 

 out the width, equal and very sparse throughout sei'iatllS 



Elytral pubescence longer and more shaggy ; abdominal punctures com- 

 pletely absent toward the sides of the last three segments, very fine and 

 sparse but visible in the middle toward base ; abdomen rather less dull.

L<. analis Lee. — Bull. U. S. Geol. Surv., 1879, V, p. 515. — Oval, strongly 

 rounded behind, nearly twice as long as wide, widest at the middle, black 

 throughout, shining ; pubescence somewhat dense, moderate in length, sub- 

 recumbent, evenly distributed, feebly mottled cinereous and fulvous, the 

 hairs robust and strongly aciculate. Head strongly and deeply punctate ; 

 punctures longitudinally coalescent, forming fine strong somewhat interlacing 

 rugie ; lateral supraorbital ridges fine and strong. Protliorax more than twice 

 as wide as long ; sides straight, strongly narrowed from base to apex, the 

 latter two-thirds as wide as the former ; basal lobe strong, truncate ; surface 

 nearly as in californkus, the punctures slightly denser. Scutellum three- 

 fourths longer than wide, fiat, finely, sparsely punctate ; sides and base 

 broadly arcuate. Eli/tra four times as long as tlie prothorax and scarcely one- 

 fourth wider ; surface shining, very obsoletely reticulate ; punctures moderate, 

 deep but variolate, separated by about one and one-half times their own 

 widths. Presternum shining, finely and very sparsely punctate, tlie punc- 

 tures larger and nearly twice as dense anteriorly ; median impressed groove 

 strong, obsolete at anterior fifth ; episterna clearly limited within throughout 

 their length, almost absolutely attaining the apex ; hypomera flat, not per- 

 ceptibly impressed at the inner angle, minutely, strongly reticulate, alutace- 

 ous, very finely, sparsely punctate. Abdomen rather sparsely punctate, finely, 

 strongly granulato-reticulate laterally and toward base, the segments polished 

 toward apex, the fifth polished, deeply, coarsely cribrate, impressed and 

 densely pubescent near the apex. Length 2.3 mm. 



Texas ; Arizona ; California. 



The largest species of the genus, related somewhat to calif ornicus, 

 but differing in its denser pubescence and punctuation, and in the 

 •extent of the prosternal side-pieces; the prothorax at base is rela- 

 tively wider, the el3-tra at the humeri not being rather abruptl}' 

 wider and somewhat prominent as in caUfornicu&.
