STAPHYLINID^E. 107 



Dimetrota (Dalotia) crucialis n. sp. Nearly as in the preceding in coloration 

 and sculpture but a little stouter, the head notably larger and rather more 

 transverse, the eyes at a little less than their own length from the base, much 

 more prominent than the short and rounded tempora, the carinae similar; 

 antennae black, paler basally, a little longer and still heavier, the joints five 

 to eleven stouter, more parallel and less gradually increasing in width, the 

 first almost as long as the next two combined, the latter mutually equal 

 in length; prothorax similar in form, very distinctly, though less greatly, 

 exceeding the head in width, slightly narrower than the elytra, the impression 

 shallow, broad, oblong and subequal from before the middle to the base; 

 elytra less abbreviated, parallel, the suture almost one-half longer than the 

 prothorax; abdomen almost similar though still broader, almost as wide as 

 the elytra, the sixth tergite (d") similar, except that the median part of the 

 apex, instead of being almost transverse, is here broadly sinuate and the small 

 prominences bordering the minute median sinus, are broader, very feeble 

 and obsolete, not discoverable except through knowledge of their existence 

 in the preceding species; sterna nearly similar, except that the metasternal 

 projection is much more acutely rounded at tip. Length i .8 mm. ; width 0.56 

 mm. California (Sta. Cruz Mts.). 



There can be but little doubt of the distinctness of these two 

 species, though both inhabit the same locality; crucialis has a 

 larger head, stouter and more parallel antennae, larger elytra, much 

 more acute metasternal projection and a generally stouter form of 

 body. 



Sableta n. gen. 



The body is here rather stout, fusoid and of pallid coloration, 

 the middle coxae well separated, the mesosternal process short and 

 very broad, not extending to the middle of the coxae and of peculiar 

 form, being parabolic in outline and broadly rounded at tip, sepa- 

 rated from the long and slender metasternum, which is narrowly 

 blunt at apex, by a very short and narrowly convex, undepressed 

 interval. The hind tarsi are well developed, with the first four 

 joints equal, the claws very slender, long and straight, curved 

 slightly only at apex. 



Sableta infulata n. sp. Very moderately convex, shining, minutely and 

 rather sparsely punctulate, not asperate, pale testaceous in color, the head 

 and antenna? not materially darker, the elytra a little darker but with a 

 broad and very pale basal margin, which is interrupted only at the base of 

 the suture, the abdomen with a blackish band occupying the fourth tergite, 

 the tip also blackish; head small, transverse, rounded at base, the eyes large, 

 convex, the tempora rapidly arcuato-convergent, the carinae strong and almost 

 entire; antennae moderately long, gradually feebly incrassate, the elongate 

 second and third joints equal, the outer joints slightly transverse, the last
