Coleopterological Notices. VI. 559 



Elytra oblong, barely two-thirds longer than -wide, one-third wider than the 

 prothorax, parallel and straight at the sides, A-ery obtusely parabolic in rather 

 less than apical third; base rectilinearly truncate, the humeri right, narrowly 

 rounded ; piinctures moderately coarse, deep and decidedly sparse. Abdomen 

 alutaceous, finely and feebly punctulate, reticulate and finely, moderately 

 densely pubescent. Length 2.6 mm. ; width 1.0. 



California (Mendocino and Napa Cos.). 



The three specimens in m}' cabinet are females, the fifth ven- 

 tral being rounded behind and feebl}- deflexed,the apex of the ab- 

 domen bristling with a few very long and erect black setoe. Va- 

 riegatus resembles luteipes almost perfectl}^, but is larger, with a 

 relatively narrower and less transverse prothorax, shorter vesti- 

 ture and black femora. 



23. L,. incertus n. sp. — Elongate, convex, polished, black, the upi>er 

 surface with a strong violaceo-nietallic lustre; legs black, the tiliise and tarsi 

 rufo-piceous; autennte piceous-black, the second and third joints paler; pubes- 

 cence short, only moderately coarse and dense, in great part denuded on the 

 elytra in large spots toward base and wide iiTCgular bands at the middle and 

 at apical fourth. Head slightly but distinctly narrower than the prothorax, 

 the eyes rather large and prominent; punctures small, moderately sparse, the 

 surface rugose laterally and toward base ; anterior impressions broad ; epistoma 

 transversely impressed and thinned toward apex but not pale; labrum intense 

 black throughout, broadly arcuate at apex; antennje slender, almost as long 

 as the head and prothorax in the male, with the tenth joint more than one- 

 third longer than wide, a little shorter in the female, with the tenth joint 

 scarcely longer than wide. Prothorax one-half or more wider than long, nar- 

 rowly rounded and widest near the base, the sides strongly convergent and 

 nearly straight thence to the obtuse apical angles; apex broadly and feebly 

 arcuate; disk finely, closely punctate and generally dull, the interspaces 

 sparsely and fineh' j)itted, coarselj- rugose toward the sides. Elytra three- 

 fourths longer than wide, parallel, obtusely rounded or parabolic liehind, quite 

 distinctly wider than the prothorax, rather finely and not densely punctate. 

 Length 2.5-2.8 mm. : width 0.75-1.0 mm. 



California (Sta. Clara Co.). 



This species is allied to variegaius, and differs in its shorter 

 and more opaque pronotum. The general characters of the de- 

 scription are taken from the male, in which sex the fifth ventral 

 is trapezoidal, broadly truncate at apex and unmodified on the 

 disk ; in the female the head is relatively slightly smaller, but 

 the eyes are almost as prominent as in the male. Five specimens. 



24. L,. aiinillatus n. sp. — Stout and oblong, convex, highly polished, 

 black with a greenish-metallic lustre; legs black, the tibiae and tarsi rufo-
