California (Fort Yuma). Mr. H. F. Wicldiam. 



One of the two specimens before me has the prothorax more 

 strongly narrowed behind than the type above described, the differ- 

 ence being probably sexual in nature. It will be observed that the 

 characters of this species are quite composite, the outer apical angle 

 of the anterior tibiae being prolonged and acute, the elytral punc- 

 tures distinctly serial in arrangement, and the anterior coxa? widely 

 separated. It is the smallest of the genus known to me from our 

 territories. 



L.. Clirtlllus n. sp. — Parallel, rather depressed, pale brownish-testaceous 

 throughout, moderately shining, tlie vestiture coarse, yellowish, moderately 

 long and dense and somewhat conspicuous. Head rather coarsely, very densely 

 punctate, the epistoma less densely so, the suture very deep, broadly arcuate ; 

 eyes moderate in size and prominence ; antennse stout, nearly one-half longer 

 than the head, the third and fourth joints subequal and each rather distinctly 

 shorter than the fifth, club small but robust, oval and rather compact. Pro- 

 tliora.r as long as wide, distinctly narrowed from apex to base, the apex broadly, 

 strongly arcuate ; base very feebly arcuate ; sides straight ; apical angles very 

 slightly obtuse, not rounded although slightly blunt, basal more broadly 

 obtuse and decidedly blunt ; disk feebly convex, broadly feebly impressed in 

 the middle except toward apex, with a fine deep canaliculation near the base, 

 moderately coarsely, very densely punctate, a little more sparsely so near the 

 apical margin. Elytra two and one-half times longer than the prothorax and 

 scarcely at all wider than the latter, not distinctly more than twice as long as 

 wide, the apex broadly, abruptly and obtusely rounded ; humeri right, not 

 rounded but a little blunt ; sides straight ; disk rather closely, confusedly 

 punctate, with two or three feebly defined, narrow, imjjunctate lines on each. 

 Aluhmen polished, minutely and very sparsely punctate. Anterior cox?e rather 

 widely separated, the prosternum polished and almost impunctate, the hypo- 

 mera rather finely and very densely so throughout. Anterior tibiie gradually 

 much broader from base to apex but with the exterior angle not at all pro- 

 duced outwardly. Length 2.7 mm. ; width 0.8 mm.

The two or three narrow, slightly oblique, impunctate lines on 

 each elytron, is a character which is also sometimes observable in 

 parallelopipedus and punctatus but much less distinctly. The 

 present species differs from cah'forvicus in its broader form, denser 

 punctuation especially of the hypomera and elytra, in its more nar- 

 rowly separated anterior coxae, and in its uneverted exterior apical 

 angles of the anterior tiljiiie, as well as in its stouter antennae with 

 much larger club and in its slightly larger but less convex eyes.
