STAPHYLINID^E. 19 



carinae fine but strong, entire; antennae rather long, incrassate only distally, 

 strongly setose, the outer joints strongly transverse, the last rapidly pointed 

 and as long as the two preceding; prothorax minutely, sparsely punctate, but 

 little wider than long, only slightly wider than the head, parallel, evenly and 

 moderately rounded at the sides, rather convex, not impressed ; elytra wider 

 than long, much wider and longer than the prothorax, finely, very distinctly 

 and closely punctate; abdomen narrower than the elytra, very slightly nar- 

 rowed near the apex, shining, minutely, sparsely punctate; mesosternal 

 process very long and gradually finely aciculate, extending to apical fifth of the 

 coxae, where it is separated from the angular mestasternum by a very short in- 

 terval, the coxae not contiguous; first four joints of the hind tarsi equal. 

 Length 2.7 mm.; width 0.65 mm. California (Sta. Barbara). 



The type, although a female, is described because of its isolated 

 characters relating to the sterna, cephalic carinae and general outline. 



Atheta pocahontas n. sp. Moderately shining, black, the elytra feebly 

 picescent, the antennae, except toward base, black; legs pale piceous-brown; 

 vestiture very short; head parallel, transverse, the eyes not prominent, at more 

 than their own length from the base; carinae fine but entire; surface with 

 rather coarse but obsolescent punctures; antennae rather short, gradually, and 

 moderately incrassate distally, the outer joints transverse; prothorax slightly 

 wider than long and very little wider than the head, with broadly rounded 

 sides which become straighter basally, widest rather before the middle, 

 not impressed, very finely, rather closely punctate; elytra large, slightly 

 transverse, much wider and very much longer than the prothorax, finely but 

 strongly, closely punctate, each deeply sinuate at apex externally; abdomen 

 much narrower than the elytra, parallel basally, feebly and .arcuately nar- 

 rowing apically, shining, minutely, sparsely punctate; mesosternal process 

 extremely long, gradually and finely aciculate, extending fully to apical fifth 

 or sixth of the coxae, separating the latter, its tip very close to the apex of the 

 acutely angulate and sharply defined metasternal projection; basal joint 

 of the hind tarsi one-half longer than the second, two to four equal. Length 

 2.6 mm.; width 0.66 mm. Virginia (Norfolk and Fort Monroe). 



Readily distinguishable by the sternal and tarsal characters; the 

 types are apparently females. 



Atheta vaticina n. sp. Similar in all of its structural characters to the pre- 

 ceding but smaller and more parallel, the vestiture longer and more shaggy, 

 the head similarly convex, shining and rather coarsely though feebly punctate, 

 the antennae notably more slender, much less incrassate distally; prothorax 

 nearly similar; elytra differing .in being very nearly as long as wide and 

 paler, rufescent; abdomen rather more strongly and distinctly punctulate; 

 fifth tergite similarly distinctly shorter than the fourth ; tarsi similar. Length 

 2.2 mm.; width 0.55 mm. New York (Willets Point, Long Island). 



Closely allied to pocahontas in general structure but differing in 

 the more slender antennae, much smaller size and more elongate 

 elytra. I have in my collection several specimens taken at Alameda,
