rugosely punctured. Legs moderate in length and decidedly 

 slender. Length 2.1 nnn.; width 0.75 mm. 



California (San Diego). I have only seen the female of this 

 species, which is one of the smallest and most isolated of the 

 genus ; it evidently' belongs to the senilis group, however, because 

 of the uniformly distributed pubescence and three-jointed anten- 

 iial club, but differs completely in the sculpture of the head and 

 pronotum. 



If). Li. exti'icatus ii. sp. — Elongate, parallel, moderately convex, pol- 

 ished, black with a reddish or cupreous lustre; legs l)lack, the tibiaj ami tarsi 

 pale ruf o-testaceous ; antenna' piceous, the basal joint black, the second testa- 

 ceous; pubescence rather long, moderately coarse, close and semi-erect, cine- 

 reous, with confused denuded spots and lines on the elytra, a fine and strongly 

 ])izigzag band behind the middle and a broader and more even non-interrupted 

 straight fascia at apical fourth being especially noticeable. Head two-thirds as 

 wide as the prothorax, the eyes moderate in size, somewhat prominent and 

 distant from the base ; surface densely and deeply punctato-rugose and dull, 

 the anterior impressions broad and fee])le; epistoma with a wide coriaceous 

 apical margin; antenute distinctly longer than the prothorax, the tenth joint 

 but slightly wider than long. Prothorax transverse, fully one-half wider than 

 long; sides strongly convergent and broadly arcuate from near the base to the 

 ))roadly obtuse apical angles; apex feebly arcuate, more .strongly so and nar- 

 rower than the projecting base; disk deeply and densely punctato-rugose, more 

 coarsely and densely so toward the sides. Elytra long and parallel, fully three- 

 fourths longer than wide, only slightly wider than the prothorax, broadly and 

 very obtusely rounded in apical fourth ; base transversely tritncate, the humeri 

 right and narrowly rounded; punctures rather coarse, deep, moderately close- 

 set, the interspaces convex and highly polished. Leg^i rather long, the hind 

 tarsi slender. Length 2.8-3.0 mm. ; width l.U-1.1.") mm. 



California (San Diego). Mr. Dunn. 



The male, serving as the t3'pe of the above description, has the 

 fifth ventral along the median line very short, not longer than the 

 fourth, the apex broadly but distinctly sinuate and the disk flat 

 and entirely unmodilied, the pubescence decumbent, ash}' and 

 normal; behind the fifth ventral, the horizontal under part of the 

 dorsal pygidium is flattened, transversely' oval and densely 

 clothed with erect blackish hairs. I cannot perceive the true 

 genital segment in any of the four specimens before me. 



Two examples from L'tah represent a feeble geographical va- 

 riet}', agreeing throughout except that the size is a trifle larger 

 and the pronotal sculpture mucli smoother toward the middle.
