62 MEMOIRS ON THE CoLEOPTERA 1 



Stout, more posteriori}' inflated, very convex, similarly colored and with 

 similar polished metallic reflection; head smaller, evenly convex, 

 the very remotely scattered and feeble punctures more evident 

 anteriorly; prothorax convex, distinctly less than twice as wide as 

 long, the sides evenly converging and very evenly, moderately ar- 

 cuate from base to apex, not becoming parallel basally, the punctures 

 very fine and sparse; elytra more oval and inflated, about a fourth 

 longer than wide, widest slightly before the middle, where they are 

 more than a fourth wider than the prothorax, the sides evenly, 

 rather strongly rounded, rapidly more converging posteriorly to 

 the apex, which is more acutely ogival than in the two preceding, 

 the impressed lines invisible, the series of well spaced and feeble 

 punctures evident, each puncture bearing a rather long erect hair, 

 these being rather more abundant and more persistent than in the 

 two preceding; under surface shining, with small and very sparsely 

 scattered punctures. Length 2.65 mm.; width 1.5 mm. Vancouver 

 Island (Victoria) aequabilis n. sp. 



5 More narrowly oval and more acuminate behind than in any of the 

 preceding, pale in color, polished throughout, the punctures of the 

 head and pronotum much larger and more numerous though widely 

 separated; head evenly convex; prothorax about twice as wide as 

 long, strongly convex, the sides broadly rounded, converging an- 

 teriorly, becoming subparallel in about basal half; elytra nearly 

 three times as long as the prothorax and scarcely a sixth wider, 

 widest well before the middle, the sides broadly rounded, gradually 

 converging and rounded to the apex, which is more produced and 

 acutely ogival than in any of the preceding, the surface without 

 trace of impressed lines but with rather regular and widely spaced 

 series of large but feeble, well spaced punctures, each bearing the 

 usual long erect bristling hair; under surface sparsely punctured, 

 pale ochreous, the abdomen acuminate posteriorly. Length 2.2- 

 2.8 mm.; width 1.1-1.3 mm - Idaho (Coeur d'Alene), Wickham. 



pallidus n. sp. 



6 Oblong-( vate, viridi-aeneous above, shining, sparsely pilose, with 

 deep, widely scattered punctures; head convex, the front with a 

 subcanaliculiform impression; prothorax transverse, "elevato-pul- 

 vinato" ; elytra with the margin reflexed; legs and antennae rufo- 

 piceous; under surface violaceous. Length 2.6-3.0 mm.; width 

 1.3-1.5 mm. Alaska (Sitka). Under bark of dead trees, rare.

 description transcribed from Mannerheim, Bull. Mosc., 1852, p. 

 342 nitidus Mots. 



There can apparently be but little doubt that the species named 

 Simplocaria nitida, by Motschulsky, belongs to this genus, and its 

 assignment to Simplocaria was probably due to the feebly impressed 

 elytral lines noted in some of the above species but which are not 

 mentioned by Mannerheim. I do not however quite comprehend
