distinct, rather sparse, two or three times sparser than those of the pronotum. 

 Length 1. 22-1. 4 mm.; width 0.6-0.73 mm. Canada, New York, Pennsylvania, 



and Iowa ovalis, sp. nov. 



Species of the Pacific coast and Alaska 20 



20 — Larger species, oblong-oval in form, rather stout, convex, polished, black, the en- 

 tire elytra bright testaceous ; legs piceous; the antenna; pale, with the club rather 

 stout ; prothorax but little more than one--half wider than long, subangularly 

 rounded at the sides slightly before the middle, then strongly narrowed to the 

 apex, finely, rather sparsely punctate, as wide at base as the base of the elytra, the 

 latter parallel and broadly arcuate at the sides, rather narrowly rounded at apex, 

 finely but strongly, rather sparsely impresso-punctale. Length 1.6 mm.; width 



0.78 mm. Alaska (Kodiak Island) fulvipennis Mann. 



Small species, shining, rather narrow and elongate-oval in form 21 



21 — Black, the elytra picescent, the legs paler ; antenna; testaceous, moderately stout, 

 two-fifth as long as the body ; prothorax short, three-fourths wider than long, 

 very slightly narrower than the base of the elytra, the sides parallel almost to 

 apical third, then strongly convergent to the apex, the punctures strong, deep 

 and close-set, dense toward the sides, the basal impression moderate, not attaining 

 the sides ; elytra parallel and broadly arcuate at the sides, ra her obtuse at apex, 

 fully three times as long as the prothorax, finely and rather sparsely punctate, the 

 punctures much less close than those of the pronotum. Length 1. 25 mm.; width 



0.6 mm. California ( Mendocino Co. ) inepta, sp. nov. 



Black, the elytra suffusedly paler toward tip, frequently pale ferruginous throughout, 

 the antenna; pale, rather stout, two-fifths as long as the body ; prothorax rather 

 small, three-fifths wider than long, slightly narrower than the base of the elytra, 

 the sides parallel for three-fifths the length, then moderately converging to the 

 apex, the punctures very fine and rather close- set, not materially denser laterally, 

 the impression rather fine and moderately deep ; elytra parallel, broadly arcuate 

 at the sides, somewhat obtuse at apex, widest at the middle, not quite three times 

 as long as the prothorax and fully a fourth wider, the punctures fine but strong 

 and moderately close-set. Length 1.2 mm.; width 0.55 mm. California (Hoopa 

 Valley, Humboldt Co.) nanula, sp. nov. 



The species in the neighborhood of ochracea form a very difficult 

 study, and my treatment of them above must be regarded as pro- 

 visional. Fallax bears some resemblance to nanula, but the antenna 

 are more approximate in insertion upon the front, being separated by 

 a third of the total width in the latter. Kamtschatica Mots., is 

 quoted by Mannerheim as occurring in Alaska, but I hav not seen it ; 

 it is ovate, black, with the elytral humeri and apex testaceous and 

 the prothorax arcuately dilated at the middle. The species lepidula of 

 Maklin, from Sitka, is also unknown to me ; it is described as oval, 

 slightly convex, shining, testaceous, with the prothorax slightly 

 rounded at the sides and deeply, the elytra finely, punctate, and the 

 antennae not approximate at base ; it must be an unusually large
