STAPHYLINID/E 163 



unimpressed; elytra slightly shorter than wide, with diverging and 

 nearly straight sides, at base barely perceptibly wider, the suture almost 

 one-half longer, than the prothorax; abdomen much narrower than the 

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

 than the fourth. Length 1.75 mm.; width 0.5 mm. California (Hoopa 

 Valley of the Trinity River Basin, Humboldt Co.). 



The female type is distinguishable readily from the female of 

 densepunctatus by its less transverse prothorax, which is much less 

 rounded at the sides, by its more parallel abdomen, smaller size 

 and narrower form. 



Tetrallus bernhaueri n. sp. Rather convex, shining, black throughout, 

 the legs not markedly paler, finely, rather closely punctate, the punctures 

 evidently asperate on the elytra, coarser, close and very strongly asperate 

 throughout on the abdomen, the pubescence rather short, fine and in- 

 conspicuous; head relatively smaller than in the preceding, two-thirds 

 as wide as the prothorax, the eyes and tempora nearly as in trinitatis, 

 the antennae also similar in general form and coloration, except that the 

 second and third joints are subequal, each a little shorter than the first, 

 the fourth subparallel and scarcely so long as wide, fifth less abruptly 

 wider, five to ten rapidly larger, the outer joints somewhat strongly 

 transverse, the last barely as long as the two preceding; prothorax a 

 little more than one-half wider than long, the parallel sides rather strongly 

 arcuate, unimpressed ; elytra scarcely visibly shorter than wide, with very 

 feebly diverging sides, at base about as wide as the prothorax, the suture 

 very broadly impressed except apically and about one-half longer than 

 the latter; abdomen much narrower than the elytra, the sides distinctly 

 converging and nearly straight, the fifth tergite shorter than the fourth. 

 Length 1.8 mm.; width 0.52 mm. California (Pasadena). 



Not closely allied to any other known to me and identifiable 

 by its very strong asperate abdominal sculpture; the unique type 

 was received from an unrecorded source and is a female; it is dedi- 

 cated with pleasure to Dr. Max Bernhauer of Griinberg, Austria. 



Pontomalota Csy. 



This is one of the most anomalous genera of our Aleocharinae and 

 is completely isolated in the Myrmedoniini. With a facies re- 

 calling very closely some gigantic Phytosid, it has the tarsi plainly 

 4-5-5-jointed. There is no trace of infra-lateral cephalic carinse; 

 the hypomera are feebly inflexed and wholly visible from a lateral 

 viewpoint and the elytral apices are deeply sinuate at each side, 

 the flanks extending posteriorly much further than the median 

 parts. The middle coxae are rather widely separated, the rounded
