STAPHYLINID^E 161 



observation seems to indicate Myrmedoniid tarsi. For the present 

 therefore I am disposed to associate the genus with Sipalia, although 

 the facies is quite different. 



Gaenima impedita n. sp. Slender, very nearly parallel, feebly convex, 

 somewhat shining, pale testaceous, the head piceous, the abdomen with a 

 subapical black cloud, the legs pale; punctures small, not dense, the 

 micro-reticulation of the abdomen unusually large, strong, polygonal; 

 pubescence rather long and coarse, not dense; head large, much wider 

 than long, barely visibly narrower than the prothorax, evidently inflated 

 basally, the eyes prominent, rather coarsely faceted, at about one-half 

 more than their own length from the base; antennae short, wholly pale, 

 the second joint cylindric, slightly shorter than the first, much longer 

 and thicker than the third, which is obconic, fourth evidently transverse, 

 fourth to tip rapidly and evenly becoming notably thick, the tenth joint 

 between two and three times as wide as long, the last briefly conoidal, 

 as long as the two preceding; prothorax about a fourth wider than long, 

 widest near the apex, where the sides are rather strongly rounded, thence 

 distinctly converging and straighter to the base, the median line impressed 

 anteriorly and again, much more broadly, near the base; elytra sub- 

 parallel, slightly shorter than wide, a fifth wider and a fourth longer than 

 the prothorax; abdomen parallel, with nearly straight sides, distinctly 

 narrower than the elytra, the fourth tergite longer than the third or fifth; 

 legs short. Length 1.5 mm.; width 0.28 mm. California (locality 

 unrecorded). 



Recognizable by the slender and subparallel form, pale coloration, 

 posteriorly narrowed prothorax, well developed elytra and the 

 generic characters given above. 



Hoplandria Kr. 



The following species is smaller and narrower than ochracea: 



Hoplandria brittoni n. sp. Moderately stout and convex, shining, 

 testaceous, the head and median parts of the pronotum blackish, the 

 elytra infumate near the scutellum and postero-externally ; abdomen 

 black throughout, the legs piceous-black; punctures rather fine, well 

 separated, the abdomen with well marked imbriform sculpture, becoming 

 dense and asperate on the fifth and sixth tergites; pubescence rather long 

 and coarse, pale, especially long and distinct on the abdomen; head but 

 little wider than long, slightly less than three-fifths as wide as the pro- 

 thorax, the eyes well developed, at less than their own length from the 

 base, the tempora at first equally prominent, then broadly rounding and 

 converging to the base; antennae blackish, pale basally, the third joint 

 much shorter than the second, fourth longer than wide, fifth to ninth 

 gradually and rapidly becoming thick apically, passing from slightly to 

 two-thirds wider than long, tenth distinctly longer and less transverse 

 than the ninth, the last ogival, as long as the two preceding; prothorax
