Li. apiCcllis n. sp. — Parallel, moderately slender, rather depressed, flat 

 above, the elytra vertical at the sides, dark rufo-ferruginous throughout, very 

 slightly shining ; pubescence very short and sparse, moderately coarse. //< ad 

 moderate, nearly as long as wide, quite distinctly narrower before than behind 

 the eyes, the latter moderate, very slightly convex and about two- thirds longer 

 than the tempora ; occiput slightly constricted at base ; upper surface feebly 

 impressed at the sides of the epistoma, finely, sparsely punctate, the punctures 

 becoming denser and coarsely tuberculous toward the sides ; antennae well 

 developed, rather stout, the pubescence rather dense, moderate in length, club 

 wide, nearly parallel, rather loose, the ninth joint distinctly shorter although 

 but little narrower than the tenth, third scarcely one-half longer than wide. 

 Prothorax scarcely visibly longer than wide; sides extremely feebly convergent 

 from apex to base, straight in direction although slightly undulated ; base 

 with a very short wide truncate median lobe ; basal angles slightly obtuse but 

 not rounded ; apex nearly transverse but feebly bilobed, the margin of the 

 lobes tumid ; disk finely, rather sparsely punctate, each puncture at the 

 summit of a small elevated tubercle ; the tubercles dense ; surface broadly, 

 feebly impressed in the middle in anterior two-thirds, also with three feeble 

 impressions near the base forming a posteriorly pointed triangle, otherwise 

 even. Elytra about two and one-half times as long as the prothorax and 

 nearly two-fifths wider ; apex semi-circularly rounded ; humeri very narrowly 

 rounded ; sides parallel andnearly straight ; disk with broadly elevated suture 

 and four rather strong straight costae on each elytron, the summit of the costae 

 distinctly, densely punctate, not very conspicuously setose, the intervals each 

 with two very approximate series of coarse close-set punctures, the small sub- 

 recumbent setae arranged as in pertenuis; scntellar series long and distinct; 

 first discal costa abruptly obsolete at apical fifth, the surface between the 

 thence feebly elevated suture and the second costa nearly flat, polished and 

 extremely sparsely, finely punctate thence to the apex. Under surface 

 throughout very coarsely, densely, deeply and distinctly punctate, the punc- 

 tures slightly transverse and feebly reniform, the small inconspicuous seta? 

 arising from their anterior margins. Legs moderate ; tarsi slender. Length 

 3.4-3.7 mm. 



California (Santa Cruz Co.). 



In some characters this remarkably distinct species is interme- 

 diate between the ordinary forms with all the elytral costa? entire, 

 and the pusillus group in which the first discal costa is abbreviated ; 

 this abbreviation is most extreme in concavus. 



I... ConcaTUS n. sp. — Rather robust, depressed, subparallel, black ; legs 

 and antennae rufo-testaceous ; upper surface alutaceous, the pubescence not 

 very coarse, extremely short, very dense throughout. Head slightly wider 

 than long, the sides arcuate and convergent before the eyes which are well 

 developed but not at all prominent, the tempora very short ; base rather 

 strongly, abruptly constricted ; surface nearly flat, with two very large feeble 

 impressions separated by a longitudinal and feeble elevation ; punctures sim-
