Coleopterological Notices, IV. 375 



parallel in basal two-thirds ; apex ogival, the sutural notch minute ; disk 

 with just visibly impressed series of coarse, deep, not very close-set punctures, 

 the intervals minutely, feebly and somewhat sparsely punctate. Abdomen 

 finely, sparsely punctured. Length 3.0 mm. ; width 1.1 mm. 



Alaska. Cab. LeConte. 



A small species allied to luridus, but narrower, more sparsely 

 pubescent, darker in col'or and with a shorter beak in the male ; the 

 antennal club is distinctly longer and larger than in luridus. In 

 form it somewhat resembles subfasciatus, but the prothorax is less 

 strongly rounded on the sides and the punctuation very much 

 coarser and sparser. 



17 I>. marginatum n. sp.— Oblong, feebly convex, rather dull, rufo- 

 testaceous ; sterna, abdomen except near the apex, a feeble clouded transverse 

 area on the pronotum before the middle, head, beak except at tip and a broad 

 subsutural vitta on each elytron, from the base nearly to the apex, more or less 

 blackish ; vestiture moderately dense, consisting of short robust recumbent 

 hairs, feebly condensed in small and paler spots on the elytra, unevenly denser 

 toward the sides of the pronotum and paler in two small approximate spots 

 before the middle. Head very densely, deeply punctate, without frontal fovea, 

 the squamules erect, dense and bristling along the inner margin of the eyes ; 

 beak as long as the head and prothorax, rather stout, deeply punctato-sulcate, 

 feebly arcuate ; antennae inserted near apical third, the basal joint of the 

 funicle as long as the next three, club moderate, piceous-black. Prothorax one- 

 third to one-half wider than long, subparallel and rounded on the sides, dis- 

 tinctly constricted behind the apex, rather coarsely, very deeply and densely 

 punctate, without impunctate line. Elytra at base one-third wider than the 

 prothorax, from more than three to nearly four times longer than the latter, 

 parallel and nearly straight on the sides, acutely ogival in apical third ; sutu- 

 ral notch rather large, deep and triangular ; striae not impressed, the punc- 

 tures moderately coarse, very deep and close-set ; intervals minutely, indis- 

 tinctly but rather closely punctate. Abdomen somewhat coarsely, moderately 

 closely punctate. Legs rather short ; femora stout, moderately but distinctly 

 dentate. Length 3.6-4.0 mm. ; width 1.4-1.6 mm. 



California. 



This is a rather distinct species, allied to vagenotatus, but always 

 easily separable by the well-defined abbreviated subsutural vitta. 



18 I>. in differ ens n. sp. — Oblong-oval, rather shining and convex, 

 dark rufo-testaceous in color, the head, beak, sterna and the elytra indefi- 

 nitely toward the middle, black or piceous ; elytral suture always narrowly 

 rufous ; tip of beak pale testaceous ; legs and antennae rufo-testaceous ; vesti- 

 ture rather sparse, consisting of short robust pointed and prostrate hairs, 

 whitish in color, confusedly condensed and subdenuded on the elytra. Head 

 not coarsely but deeply, very densely punctate, finely sparsely squamulose,
