mesosternal tip by a moderately short and very deep interval which is 

 acutely ridged at the bottom. Length 2.65 mm.; width 0.62 mm. Cali- 

 fornia (Mountains near Claremont), Baker. 



To be distinguished readily from the last, though somewhat 

 similar in the rapidly more transverse distal antennal joints, by its 

 much less developed prothorax. 



Atheta stoica n. sp. Large and stout, moderately convex, feebly 

 shining, minutely and not very closely punctate, asperulately and more 

 closely on the elytra, minutely and sparsely on the polished abdomen, 

 which is extremely finely and densely though almost obsoletely strigilate 

 transversely; pubescence fine, very short, palish; color black, the elytra 

 dark yellowish-testaceous, just visibly infumate toward the scutellum, 

 the legs pale; head relatively rather small, wider than long, two-thirds as 

 wide as the prothorax, the eyes large, at two-thirds their length from 

 the base, the tempora very nearly as prominent, parallel and straight 

 for some distance, then rounding to the base, the carinae rather strong, 

 entire, the front with the median line rather broadly punctureless, finely, 

 feebly impressed on the occiput; antennae long and very slender, only 

 slightly and very gradually incrassate, blackish, the basal joint a little 

 paler, the third longer than the second and as long as the first, fourth 

 much longer, the outer joints rather longer, than wide, the last acutely 

 ogival, much shorter than the two preceding; prothorax large, fully one- 

 half wider than long, parallel, with moderately rounding sides, becoming 

 much more rounded and converging apically, the median line finely and 

 feebly impressed throughout; elytra large, moderately transverse, with 

 just visibly diverging sides, at base slightly though evidently wider, the 

 suture two-fifths longer, than the prothorax; abdomen distinctly nar- 

 rower than the elytra, parallel, gradually and very slightly narrowing 

 behind, the fourth and fifth tergites equal in length. Length 3.0 mm.; 

 width 0.89 mm. California (San Francisco). 



The long and very slender antennae, with all the joints longer than 

 wide, are very aberrant for true Atheta, but I do not now see how it 

 can be placed elsewhere; the general facies is purely Athetid. 



Atheta intacta n. sp. Rather stout, narrowing anteriorly, moderately 

 convex and shining, the abdomen strongly shining, with numerous fine 

 punctures basally, becoming sparse posteriorly and with distinct, though 

 extremely close, minute transverse strigilation; punctures throughout 

 anteriorly close-set, small but strongly asperate, not minute on the head 

 and parted along the middle as in the preceding; pubescence very fine 

 and short, palish; color throughout nearly as in the preceding; head mod- 

 erately transverse, fully three-fourths as wide as the prothorax, the eyes 

 rather prominent, at fully two-thirds their length from the base, the tem- 

 pora less prominent, straight and parallel near the eyes but thence 

 strongly rounding to the base, the carinae very fine, far from entire; 

 antennae moderately long and incrassate, very gradually so and blackish 

 distally, picescent basally, the third joint as long as the first, very slightly
