STAPHYLINID.E 121 



Atheta (Nemota) meticulosa n. sp. Slender, subparallel, rather con- 

 vex, polished throughout, the punctures very fine, sparse, well separated 

 and but little larger on the elytra, the abdominal reticulation rather 

 coarse and polygonal but feeble, especially toward base; pubescence 

 sparse and inconspicuous; color rufo-piceous, the head and abdomen 

 black, the elytra but just visibly paler than the prothorax, the legs pale 

 piceous-brown; head nearly as long as wide, three-fourths as wide as 

 the prothorax, just visibly and gradually broader basally, the eyes at 

 more than their own length from the base, the tempora abruptly oblique 

 at the extreme base, the carinae very fine, far from entire; antennae 

 piceous, paler basally, notably short but slender, gradually and only slightly 

 incrassate, the third joint very little shorter than the second but more 

 narrowed at base, fourth fully, the fifth nearly, as long as wide, the outer 

 joints barely two-fifths wider than long, the last ogival and as long as the 

 two preceding; prothorax less than two-fifths wider than long, parallel, 

 moderately and subevenly arcuate at the sides, not clearly impressed at 

 base; elytra moderately transverse, with feebly diverging straight sides, 

 at base about as wide as the prothorax, much wider at apex, the suture 

 a third longer; abdomen narrower than the elytra, slender, very gradually 

 and just visibly narrowing from near the base to apex, the fifth tergite 

 fully one-half longer than the fourth ; middle coxae very slightly separated, 

 the metasternum perfectly transverse medially, without trace of even 

 an arcuation. Length 1.7 mm.; width 0.38 mm. California (Paraiso 

 Hot Springs, Monterey Co.). 



Seemingly the only species with which this can be compared is 

 the more southern perpera Csy., but, although the head has about 

 the same reduced development, perpera is blacker and a little 

 stouter, with the elytra longer, more parallel and more punctured. 



Atheta (Nemota) informalis n. sp. Somewhat stouter than usual, 

 rather convex, strongly shining, the micro-reticulation very feeble, 

 large but feeble and polygonal on the elytra and abdomen; punctures 

 very fine, not close or asperate; color deep black, the elytra scarcely 

 less black, the legs black; head large, slightly wider than long, five-sixths 

 as wide as the prothorax, the eyes at fully their own length from the base, 

 the tempora parallel and arcuate, more prominent than the eyes, the 

 carinae wholly wanting; antennae moderately long, rather thick, gradually 

 and distinctly incrassate, black, the second and third joints subequal, 

 the fourth obtrapezoidal, nearly as long as wide, the succeeding joints 

 moderately transverse, the last large, ogival, rather longer than the 

 two preceding; prothorax small, about a third wider than long, parallel 

 and evenly, moderately rounded at the sides, scarcely at all impressed 

 at base; elytra ample, slightly shorter than wide, with evidently diverging 

 and almost straight sides, at base between a fourth and third wider, the 

 suture one-half longer, than the prothorax, the apices somewhat rounded 

 and oblique anteriorly toward the suture, not sinuate externally; ab- 

 domen slightly narrower than the elytra, much wider than the prothorax, 

 parallel, with feebly arcuate sides, the subequal fourth and fifth tergites
