STAPHYLINID.E.

The sternal structure, form of the antennae and male sexual 

 characters will distinguish this species quite readily; it is scarcely 

 a normal Atheta but seems hardly worthy of subgeneric separation. 



Atheta reposita n. sp. Stout, fusoid, very moderately convex, feebly 

 shining, the abdomen strongly so and strongly and transversely though not 

 very closely strigilate; punctures throughout anteriorly fine, asperulate and 

 close-set; color dark piceous, the head and abdomen black, the elytra paler; 

 legs pale, the antennae dark; head transverse, the eyes rather convex, at a 

 little less than their own length from the base, the carinae fine but distinct 

 and entire; antennae moderately long, slender, feebly and gradually incras- 

 sate, the outer joints but little wider than long, the second and third long 

 and equal; prothorax relatively rather small, very moderately transverse, 

 parallel, evenly and strongly arcuate at the sides, much wider than the head 

 and correspondingly much narrower than the elytra, finely, feebly impressed 

 along the median line; elytra large, with somewhat diverging straight sides, 

 rather transverse, very much longer as well as wider than the prothorax; 

 abdomen gradually tapering with straight sides from base to apex, much 

 narrower than the elytra, unusually closely but very finely punctulate, the 

 fifth tergite scarcely longer than the fourth, the sixth (c?) with a slender 

 porrect process at each side of the apex, and, at the middle, two more obtuse 

 and subtuberculiform shorter teeth, separated by a gentle sinus and mutually 

 slightly more distant than either from the lateral processes, their apices 

 in the same transverse line as the latter; mesosternal process extending to 

 apical fourth of the coxae, gradually prolonged but rather wide apically, 

 its apex narrowly rounded or subacute, rather well separated from the very 

 short and broadly, obtusely angulate metasternum; hind tarsi long, the basal 

 joint shorter than the second. Length 2.6 mm.; width 0.75 mm. Utah 

 (southwestern), Weidt. 



The general form of this species is not unlike carlottce, but with 

 very different male sexual characters and conformation of the 

 sterna. 



Atheta ostenta n. sp. Allied to the last but less stout and rather less 

 shining, the similarly asperulate punctures even denser, the abdomen nearly 

 similar in sculpture and punctuation; color black, the elytra pale, the legs, 

 still paler but with piceous femora, the antennae dark; head similar, the 

 eyes slightly smaller, at about their own length from the base, the carinae 

 distinct and entire; antennae nearly similar but with the equal second and 

 third joints rather shorter and the outer joints more transverse; prothorax 

 similar but relatively larger, the elytra smaller, the former moderately trans- 

 verse, parallel and rounded at the sides, much wider than the head, not 

 impressed on the median line but feebly before the scutellum; elytra moder- 

 ately transverse, more parallel, much wider as well as longer than the pro- 

 thorax; abdomen much narrower than the elytra, parallel, narrowing slightly 

 apically, the fifth tergite slightly longer than the fourth, the sixth (d") with 

 a smaller, porrect and acutely aciculate process at each side of the apex 

 and two very short obtuse median projections, the disposition of the four
