STAPHYLINID^:. 63 



Echidnoglossa eminens n. sp. Stout, black or slightly picescent 

 throughout, the legs blackish, the tibiae slightly, the tarsi distinctly, paler; 

 integuments rather shining, the punctures of the head and pronotum very 

 minute and comparatively sparse, of the elytra fine and closer but well 

 separated, of the abdomen distinct but not coarse and well separated in 

 the impressions, minute and close elsewhere, the pubescence rather long 

 and coarse, palish and distinct; head small, as long as wide, evenly 

 semicircularly rounded behind the eyes, the antennae notably long, 

 gradually very distinctly incrassate and thick distally, blackish, but 

 little paler basally, of the usual structure, the outer joints as long as 

 wide, the last unusually long, longer than the two preceding, with a 

 moderate medial constriction; prothorax large, convex, longer than wide, 

 much wider than the head, nearly parallel, narrowing in about anterior 

 two-fifths; elytra large, parallel, slightly shorter than wide, of the usual 

 form, three-fourths wider and a third longer than the prothorax, im- 

 pressed behind the scutellum; abdomen distinctly narrower than the 

 elytra, parallel, with evidently and evenly arcuate sides, widest at the 

 middle, the first five tergites equal in length, strongly transverse, less 

 convex than in the typical forms. Length 3.3 mm.; width 0.75 mm. 

 California (Siskiyou Co.). 



Belongs near grandicollis and with the same general form and 

 peculiar minute punctures even on the elytra, but differing in the 

 much longer, heavier and more incrassate antennae, relatively 

 narrower, more elongate and more anteriorly narrowed prothorax, 

 more rounded and less truncate base of the head and sparser 

 punctulation of both these somites; the pubescence, also, is 

 longer, coarser, paler and much more conspicuous. These two 

 species constitute a group, at least of subgeneric weight in having 

 the abdomen parallel, with the three basal impressions not coarsely 

 and densely punctate, in the smaller head and more developed 

 prothorax and in the very minute dense punctures of the integu- 

 ments throughout. 



In my last revision of this genus (Ann. N. Y. Acad. Sci., VII, p. 

 312), I made some statements which were due to too hasty obser- 

 vation and which it will be necessary to withdraw. Exilis is by 

 no means a synonym of eximia, for example, the size being much 

 smaller and the form more slender, but especially because the 

 antennae are much smaller, less incrassate and with the outer 

 joints very evidently shorter than wide. Furthermore, though 

 there are some sexual differences in the size of the antennae and 

 prothorax, these discordances are very slight and there are no 

 apparent sexual peculiarities of color or sculpture. The errors 

 were caused by confounding several distinct species.
