98 MEMOIRS ON THE COLEOPTERA 



15 Legs varicolored as in some of the preceding species, the femora 

 black, the trochanters paler, the tibiae and tarsi rufous, the former 

 blackish at tip. Body oblong, unusually depressed, shining, black, 

 the epipleura piceous, the antennae and trophi pale testaceous; 

 mandibles black, testaceous ante-apically; head moderate, with the 

 usual moderate prominent eyes, small foveae and slender antennae; 

 prothorax very nearly one-half wider than long, the apex rather 

 feebly sinuate, narrower than the base, the basal bead fine but 

 entire, the angles nearly right through distinctly rounded; sides 

 broadly arcuate, very slightly converging and nearly straight pos- 

 teriorly; surface rather gradually declivous laterally, the fine gutter 

 becoming slightly wider posteriorly and gradually disappearing, but 

 not punctate, near basal third, the foveae short, very shallow, finely 

 and rather sparsely punctate, the feeble broad convexity thence to 

 the sides with very fine, sparse and indistinct punctures; marginal 

 bead unusually fine and thin; elytra not quite one-half longer than 

 wide, obtusely rounded in apical third, about a fifth wider than the 

 prothorax, the sides parallel and nearly straight, rounding slightly 

 at base, the sinus very feeble though evident; striae rather fine, 

 feebly impressed, the scutellar deep, free, the intervals glossy, very 

 slightly convex, the puncture small, near apical fourth; basal joint 

 of the hind tarsi equal in length to the fifth. Length (cf ) 8.7 mm.; 

 width 2.4 mm. British Columbia (Frazier Valley). Probably allied 



closely to carbonatus Lee fugitans n. sp. 



Legs uniform pale testaceous throughout 16 



16 Surface between the pronotal foveae and the sides narrowly convex, 

 becoming compressed and cariniform basally. Piceous-black in 

 color, the elytra paler and more brownish and with a feebly sub- 

 metallic gloss; under surface nearly black, the epipleura and legs 

 pale flavo-testaceous; antennae' and trophi testaceous, the mandibles 

 almost uniformly pale throughout; head fully three-fifths as wide 

 as the prothorax, the eyes very prominent, the foveae minute and 

 punctiform; antennae slender; prothorax not quite one-half wider 

 than long, the sides rounded throughout, less so and somewhat 

 converging basally, the base feebly arcuato-truncate, with the angles 

 obtuse and distinctly rounded, much wider than the evidently 

 sinuate apex, the basal bead fine but strong and entire; surface 

 very finely reflexed at the sides apically, the gutter gradually 

 widening and feebler posteriorly but traceable nearly to the base, 

 the anterior transverse impression distinct medially though not 

 very deep, the stria fine but rather broadly impressed, the foveae 

 short, deep, more rounded than usual, rugoso-punctate, sharply 

 separated from the lateral subexplanate region by a basally rather 

 acute carina, this part with minute sparse obsolescent punctulation; 

 elytra one-half longer than wide, barely at all wider than the pro- 

 thorax, obtusely rounding in apical third, the sides feebly arcuate, 

 the sinus obsolete, the edge simply straight; striae fine but deeply 

 impressed, the intervals rather strongly convex, flatter laterally, 

 the puncture coarse, deep and rather before apical third; basal
