Casey — Observations on the Staphylinidae. 383 



9.6 mm.; width 1.35 ram. California (Truckee — elevation 5800 feet), 

 — H. F. Wickham limbalis n. sp. 



7 — Body larger and much stouter, black, the abdomen somewhat picescent; 

 elytra flavo-testaceoos, with the apical margin feebly and very narrowly 

 Infumate, the legs testaceous, the antennae dark red-brown throughout; 

 head well developed, coarsely and somewhat closely punctured except 

 broadly toward the middle, the under surface also strongly punctured; 

 prothorax longer than wide, much narrower than the head, strongly 

 narrowed posteriorly; elytra large, longer than wide, equal in length 

 to the prothorax and distinctly wider, almost as wide as the head, the 

 punctures much less coarse than In the preceding two species and more 

 numerous, graduUy rather close-set toward the suture, the medial 

 series of coarser punctures distinct except toward tip; abdomen mi- 

 nutely, feebly and sparsely punctulate, polished as usual. Length 6.IS- 

 8.5 mm.; width 1.2-1.4 mm. California (Sta. Clara and Sta. Cruz, — 

 under pine bark in February) corticalis n. sp. 



Body small and slender, black, the legs and elytra pale testaceous, the 

 latter feebly infumate at the apex, the antennae piceo -testaceous; head 

 less developed, the punctures coarse and deep but unusually sparse 

 even toward the sides, strong but rather sparse on the under surface; 

 antennae more noticeably longer than the head than in the preceding 

 species; prothorax elongate, longer than the head and only very 

 slightly narrower, moderately narrowed posteriorly; elytra rather 

 smaller than usual, longer than wide, not quite as long as the pro- 

 thorax and obviously wider, about as wide as the head, the punctures 

 only moderately coarse, rather sparse throughout, lineate at the middle 

 as usual. Length 6.2 mm; width 0.88 mm. California (Siskiyou Co.). 



debilis n. sp. 



8. — Body moderately large and slender, black, the abdomen somewhat 

 picescent, the legs and elytra clear and bright rufous, the latter some- 

 what infumate at base, the antennae dark rufo-piceous; head well 

 developed, elongate, parallel, the sides nearly straight, the base trun- 

 cate, with the angles rather narrowly rounded; second and third an- 

 tennal joints equal in length, the former somewhat the thicker as usual; 

 surface only moderately coarsely and very remotely punctate even 

 laterally, the punctures sparse on the convex flanks, becoming strong 

 but only moderately coarse and less sparse over the flattened under 

 surface ; prothorax of the usual form, narrower than the head, elon- 

 gate, narrowed posteriorly; elytra notably elongate, as long as the 

 prothorax and distinctly wider, not as wide as the head, the punctures 

 only moderately coarse, spar.«e and confased in arrangement, with the 

 usual close-set medial series Indistlacc. Length 7.7 mm. ; wi;1th 1.1 

 mm. Texas (Houston), Alabama (Cltronelle) and West Virginia. 



Inridipennlf n. sp. 



Body smaller and very slender, black, the abdomen rufo-piceous but clouded 

 darker toward tip, the elytra pale and bright luteo-flavate, with the 

 base — more broadly — and the flanks, abruptly black ; legs pale flavate, 

 the antennae dark rufous throughout, rather thick and nearly as in 

 luridipennis ; head elongate, parallel, remotely and only moderately 

 coarsely punctate, the convex flanks still more remotely, the under
