wider than the elytra, minutely, more densely and much more asper- 

 ately punctulate, the three basal impressions polished but with rather 

 numerous larger, though obsolescent, scattered punctures. Length 

 2.4 mm.; width 0.58 mm. California (San Bernardino Mts.), — H. C. 

 Fall parripennis n. sp. 



Of occidua I secured a large series, showing that the very 

 pale coloration is a constant specific character; of lucida I 

 have, however, only a single specimen; it is of equally pale 

 color, but may be distinguished from the male of occidua., in 

 which the prothorax is also very obviously narrower than the 

 head, by the more elongate and narrower form of that part 

 of the body, relatively much larger head and sparser abdom- 

 inal sculpture. The species of this genus will doubtless 

 prove to be numerous in California and perhaps also the coast 

 districts to the northward. 



There are two species described under the generic name 

 Falagria, by LeConte, which I have not been able to place 

 in the above revision ; they may be described as followsjf rom 

 the published characters: — 



Form elongate, subdepressed, densely punctulate, finely pubescent; head 

 rectilinearly truncate at base, the neck obviously narrower than in 

 Tachyusa; basal angles right and rounded; antennae fuscous, longer 

 than the head and prothorax, slightly thickened externally but with the 

 outer joints somewhat loose and not closely placed as they are in typical 

 Falagria, the first three joints elongate as usual; prothorax slightly 

 longer than wide, as wide as the head, obliquely truncate at each side 

 of the apex, the sides converging slightly behind; base broadly rounded, 

 the surface flattened, feebly but broadly channeled; elytra wider than 

 the prothorax but not at all longer, the tip truncate, the outer angles 

 acute ; abdomen slightly narrowed at base, impressed as usual, the 

 impressions irapunctate, the surface smooth, paler toward base, the 

 apex testaceous ; legs testaceous, the basal joint of the hind tarsi not 

 as long as the three following combined, the latter diminishing slightly 

 in length. Length 3.6 mm. Lake Superior raga Lee, 



Form depressed, piceous -black, the abdomen piceous; legs and basal parts 

 of the antennae testaceous; shining, finely pubescent; head large, par- 

 allel, the base broadly truncate with the angles rounded, sparsely punc- 

 tulate, with an impressed frontal fovea, the occiput briefly canaliculate; 

 antennae not longer than the head and prothorax and less slender than 

 usual, but slightly thickened distally ; prothorax trapezoidal, moderately 

 narrowed behind, somewhat shorter than wide, punctulate, deeply can-
