Sail Mateo Co., 1 ? (Mr. Fuclis). 



The anterior tarsi are very distinctly dilated toward base. 

 Tliis species can be at once recognized by its black color, 

 slightly transverse protliorax, and the sides of the latter, 

 which are slightly arcnate and not at all sinuate. 



12 — L, lepida ^- *^P — Rather robust, dark piceous throughout, head aud 

 prouotuni scarcely perceptibly paler; abdomen veiy slightlj' paler at the imme- 

 diate apex; legs pale, ferruginous-yellow; antennas dark fuscous, pale testa- 

 ceous at tip, basal joint dark rufous; pubescence rather long aud dense ou the 

 elytra and abdomen, denser and more sericeous ou the latter, elsewhere very 

 sparse; integuments very feebly alutaceous, shining. Head large, sub-tri- 

 angular; base broadly and feebly sinuate, angles rather broadly rounded; 

 sides very feebly convergent anteriorly, long, distinctly arcuate; epistomal 

 apex broad, squarely truncate; antennal tuberculations very small aud rather 

 feeble; surface finely, densely and eveulj' punctate; median line rather nar- 

 row; antennae slender, much shorter than the head aud prothorax together, 

 second joint distinctly shorter than the third and slightly louger than the 

 fourth, tenth as long as wide. Prothorax as long as wide, distiuctlj'' nar- 

 rower than the head; sides feebly convergent from apex to base, straight in 

 the middle; base broadly truncate in the middle; basal angles broadly 

 rounded, apical very slightly less so; sides thence very strongly convergent 

 and straight to the nuchal emargiuatiou, which is more than one-third as 

 wide as the disk and very broadly rounded; disk transversely aud very feebly 

 convex above, strongly aud rather abruptly so at the sides, finely and feebly 

 punctate, sparsely so near the middle, more coarsely and closely at the sides; 

 median line rather broad, equal throughout; very near the base there is a 

 very feeble median stria. Elytra at base just perceptibly narrower than 

 the pronotum; sides feebly divergent posteriorly and nearly straight; to- 

 gether broadly and extremely feebly sinuate behind; disk distinctly longer 

 than wide and slightly longer than the pronotum, rather depressed, narrowly 

 impressed along the slightly elevated suture, rather finelj'-, evenly, densely 

 and sub-rugulosely puuctate. Abdomen at base very slightly narrower than 

 the elytra; sides very feebly divergent posteriorlJ^ nearly straight; surface 

 very minutely and densely, feebly and snb-asperately puuctate, Legs mode- 

 rate; first joint of the posterior tarsi one-half longer than the second, slightly 

 longer than the fifth. Length 5.0 mm.

The description is taken from the male, in which the fifth 

 segment is transversely trunctate at apex, the edge being
