STAPHYLINID^: 125 



rufescent, the legs pale brown; pubescence short, stiff, subcinereous; 

 head barely wider than long, almost four-fifths as wide as the prothorax, 

 parallel, the eyes evidently prominent, at much more than their own length 

 from the base, the tempora equally prominent, parallel and strongly, 

 evenly rounded, more converging basally, the carinse wholly wanting; 

 antennae piceous, long, slender, just visibly incrassate distally, the 

 second joint evidently longer than the strongly obconic third joint and 

 very much shorter and more slender than the first, four to six slightly- 

 longer than wide, seven to ten not quite so long as wide, the last acutely 

 pointed, not as long as the two preceding; front feebly impressed on the 

 median line centrally; prothorax a fifth wider than long, widest anteriorly, 

 the sides there broadly rounded, thence slightly converging and nearly 

 straight to the base, the surface with a very feeble transverse ante-scu- 

 tellar impression; elytra large, almost as long as wide, subparallel, with 

 very straight sides, almost a third wider and one-half longer than the 

 prothorax; abdomen narrow and parallel, with straight sides, finely, 

 sparsely punctulate, the tergites equal, the sixth (cf ) arcuato-truncate 

 at apex, the side angles obtuse but with the points sharp and slightly 

 reflexed; in the middle there are two very feeble prominences, much less 

 separated than either from the side angles, the sixth ventral evenly 

 parabolic. Length 2.3 mm.; width 0.6 mm. California (Berkeley, 

 Alameda Co.). 



Not closely related to any other species but perhaps best placed

Atheta (Adota) insons n. sp. Slender, very feebly convex, resembling 

 the preceding in coloration and sculpture, the latter however feebler, 

 so that the lustre is evidently shining throughout, the pubescence short 

 and close; head as long as wide, only slightly narrower than the prothorax, 

 the eyes small, moderately prominent, at almost one-half more than 

 their own length from the base, the tempora scarcely so prominent, 

 parallel and straight for a long distance, then rounding to the base, 

 the carinae wholly wanting; antennae dark piceous, paler basally, only 

 moderate in length, rather thick distally, the joints two to six equal in 

 thickness and slender, the former about as long as the first but more 

 slender, only a little longer than the third, four to six slightly elongate, 

 seven to ten rather abruptly wider and feebly progressively incrassate, 

 all evidently shorter than wide, the tenth a little longer than the ninth, 

 the last about as long as the two preceding; median line of the front 

 rather deeply impressed centrally; prothorax small, about a fourth wider 

 than long, nearly as in the preceding, except that the sides are more 

 narrowly rounded nearer the apex and thence nearly straight and evi- 

 dently converging to the base; elytra quadrate, two-fifths wider and three- 

 fifths longer than the prothorax; abdomen as in the preceding, except that 

 the sixth tergite (cf) is transversely truncate at tip, the truncature 

 limited at each side by a simple angle, which is minutely sharp and 

 reflexed at tip, the sixth ventral almost circularly rounded. Length 

 2.2 mm.; width 0.46 mm. California (San Diego).
