STAPHYLINID.E. 109 



abdomen shining but with the minute punctures rather close, and with 

 the minute sculpture not very close and in irregular transverse wavy 

 lines; punctures dense and asperulate, the pubescence moderate, palish; 

 color dark piceous, the head and abdomen in great part blacker, the 

 elytra tawny-yellowish, infuscate about the scutellum and postero- 

 externally, the legs pale; head slightly transverse, two-thirds as wide as 

 the prothorax, parallel, the eyes large, at a little less than their own length 

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

 for a long distance, then gradually rounding to the base, the carinae 

 fine, subentire; antennae blackish, somewhat paler basally, moderately 

 long, gradually and not strongly incrassate, the third joint slightly longer 

 than the second, fourth a little longer than wide, the fifth as long as wide, 

 the outer joints becoming distinctly transverse, the last conoidal, not 

 quite so long as the two preceding; prothorax well developed, two-fifths 

 wider than long, parallel and evenly, moderately rounded at the sides, 

 the median line feebly impressed basally; elytra but slightly transverse, 

 with feebly diverging sides, at base very slightly wider, the suture a 

 third longer, than the prothorax; abdomen slightly narrower than the 

 elytra, parallel, with nearly straight sides, the fifth tergite slightly longer 

 than the fourth, the sixth (9 ) very broadly rounded at apex, becoming 

 slightly sinuate medially; mesosternal process long but with the tip not 

 very fine, moderately separated from the somewhat small but angulate 

 metasternal projection. Length 2.7 mm.; width 0.7 mm. California 

 (San Diego). 



Distinguishable by the nearly parallel outline, form of the head 

 and dullish lustre. 



Atheta repexa n. sp. Moderately stout, somewhat shining, finely, 

 closely, asperately punctate, the abdomen polished, minutely, sparsely 

 punctate, with the micro-reticulation transversely polygonal; pubescence 

 rather long and coarse, pale; color piceous-black, the head and entire 

 abdomen deep black, the elytra pale tawny-yellow, blackish at the 

 scutellum but not evidently so postero-externally, the legs pale; head mod- 

 erate, rather transverse, almost four-fifths as wide as the prothorax, the 

 eyes prominent, at three-fourths their length from the base, the tempora 

 less prominent, straight and parallel for a short distance, then strongly 

 rounding to the base, the carinse fine, not quite entire; antennae black, 

 pallescent basally, moderate in length, gradually rather strongly in- 

 crassate distally, the second and third joints equal, fourth much longer 

 than wide, fifth as long as wide, the outer joints fully one-half wider 

 than long, the last conoidal, somewhat longer than the two preceding; 

 prothorax rather small, two-fifths wider than long, parallel and moderately 

 rounded at the sides, which are more rounding and convergent apically, 

 the impression obsolescent; elytra parallel, only slightly transverse, fully 

 a third wider and one-half longer than the prothorax; abdomen much 

 narrower than the elytra, parallel, narrowing very slightly behind, the 

 fourth and fifth tergites equal in length; metasternal projection broad, 

 evenly triangular, about twice as wide as long, separated from the acute
