STAPHYLINID/E 169 



antennae brown, rather long, gradually and distinctly incrassate distally, 

 the second joint as long as the first but much thinner, slightly longer than 

 the third, fourth a third longer than wide, tenth about a fourth wider 

 than long, the last not quite as long as the two preceding; prothorax 

 parallel, very nearly as long as wide, slightly widest a little before the 

 middle but with the sides broadly rounded, gradually less so basally and 

 more so apically, the median line impressed shallowly from near the apex 

 to the base in more than median fourth of the width; elytra not large, 

 only slightly wider than long, parallel, with feebly arcuate sides, less 

 than a third wider and a third longer than the prothorax, the humeri 

 only very moderately exposed basally; abdomen only just visibly inflated 

 posteriorly, behind the middle as wide as the elytra, and, at base, very 

 nearly so, the fifth tergite much shorter than the fourth. Length 2.3 mm. ; 

 width 0.5 mm. Washington State (North Yakima), Wickham. 



Quite distinct in the peculiar form of the prothorax, which is 

 subparallel and rather broadly rounded at the sides; also in the 

 close asperate punctures and median impression of that somite, 

 and the unusually parallel form of the body. 



Gnypeta uteana n. sp. Rather slender, moderately convex, strongly 

 shining, black, the elytra feebly picescent, the legs piceous-black, pale 

 distally; punctures fine, rather sparse, slightly closer and somewhat 

 asperate on the elytra, fine and moderately close on the abdomen, the 

 three tergitical impressions deep but somewhat fine, the well separated 

 coarsish punctures forming scarcely more than a single line; pubescence 

 moderate, not conspicuous; head fully as wide as the prothorax if not 

 somewhat wider, a little wider than long, the eyes well developed, promi- 

 nent, at scarcely their own length from the base, the less prominent 

 tempora rounding in strong even arc to the base, becoming parallel 

 behind the eyes; antennae piceous-black, moderately long, very slender, 

 gradually and very moderately incrassate distally, the first three joints 

 subequal in length, fourth obtrapezoidal, fully a third longer than wide, 

 fifth as long as wide, the joints thence gradually larger, the tenth about 

 a third wider than long, the last sharply ogival, as long as the two pre- 

 ceding; prothorax very slightly wider than long, just visibly wider 

 anteriorly than at base, the sides subparallel and very slightly arcuate, 

 rounding anteriorly to the apex, the surface unimpressed, excepting two 

 small and aproximate ante-scutellar foveae; elytra but little shorter than 

 wide, two-fifths wider and nearly one-half 4onger than the prothorax, the 

 apices slightly sinuate laterally; abdomen much narrower than the 

 elytra, parallel, with almost straight sides, the fifth tergite nearly one-half 

 longer than the fourth. Length 2.0 mm.; width 0.5 mm. Utah (south- 

 western), Weidt. 



An aberrant species in the form of the prothorax; it may follow 

 the last in a general arrangement and the two may come in just 

 before the following at the end of the genus:
