374 Coleopterological Notices, IV. 



15 D. ClineatlllllS n. sp. — Rather narrowly cuneate, convex, polished, 

 hlack throughout, the pronotum and elytra occasionally with small feebly- 

 marked paler spots near the humeri ; vestiture sparse, consisting of short 

 robust recumbent hairs, whitish in color and confusedly and vaguely con- 

 densed in spots and transversely wavy lines behind the middle of the elytra. 

 Head strongly bat only moderately closely punctate, the fovea almost obsolete ; 

 beak somewhat stout, cylindrical, equal in thickness, strongly, longitudinally 

 furrowed and closely, obscurely punctate in both sexes, but differing greatly 

 in length ; in the male decidedly short, as long as the head and prothorax, 

 straight, feebly bent near the apex, the antenna? inserted at apical third; in 

 the female rather long, evenly, very feebly arcuate, about two-fifths as long 

 as the body, with the antennae inserted rather beyond apical two-fifths ; an- 

 tenna? somewhat slender, the first funicular joint not quite as long as the next 

 three in both sexes, the second about as long as the next two in the female, 

 but slightly shorter in the male, rufo-testaceous with the club darker. Pro- 

 thorax nearly two-fifths wider than long, not differing greatly in the sexes, 

 parallel and broadly rounded at the sides, strongly constricted and broadly 

 tubulate at apex, coarsely deeply and moderately closely punctate, without 

 distinctly marked impunctate area. Elytra at base distinctly wider than the 

 prothorax, fully three times as long as the latter, broadly feebly inflated be- 

 hind, obtusely ogival in apical third ; striae feebly impressed, coarsely deeply 

 and closely punctate, the intervals minutely and not very densely so. Abdo- 

 men rather strongly indistinctly and subrugosely punctured. Length 3.3-3.7 

 mm. ; width 1.3-1.6 mm. 



California (Siskiyou Co.). 



A small, somewhat narrow and convex species allied to lurid us t 

 but distinguishable by its black coloration and by the much greater 

 sexual disparity in the length of the beak, the latter being actually 

 a little shorter in the male than in the corresponding sex of luridus. 

 The body is narrower and the antennal club larger and relatively 

 longer in cuneatulus. 



16. I>. alaskanilS n. sp. — Narrow, oblong, subparallel, moderately con- 

 vex, shining, piceons-black, the elytral suture and flanks pronotum at base and 

 apex, legs and antennae, except the club, paler ; vestiture very sparse, con- 

 sisting of short robust recumbent hairs, condensed, larger and whiter in very 

 small remote spots on the elytra. Head strongly deeply and closely, the beak 

 very densely and opaquely, punctate, the latter longitudinally channeled, in 

 the male rather stout, feebly arcuate toward apex, equal in length to the head 

 and prothorax, the antennae inserted at apical third, the basal joint of the 

 funicle rather robust, not as long as the next, three. Prothorax one-half wider 

 than long, subparallel and rounded on the sides, strongly constricted at apex, 

 the latter broadly and briefly tubulate, nearly as wide as the base ; disk rather 

 coarsely deeply and somewhat sparsely punctate, with a central feebly-defined, 

 elongate subimpunctate area Elytra at base about one-third wider than the 

 prothorax, rather more than three times as long ; sides almost straight and
