STAPHYLINID/E. 151 



almost obsolete; elytra rather small and short, subparallel, the suture evi- 

 dently not quite as long as the prothorax; abdomen nearly as wide as the 

 elytra, gradually and very feebly tapering and with nearly straight sides 

 throughout, the tergites gradually increasing in length posteriorly. Length 

 1.8 mm.; width 0.42 mm. California (Lake Tahoe). 



Comparable only with shastanica, but a little broader throughout 

 and with the elytra shorter and much more transverse, the pro- 

 thorax still more inflated laterally and the antennae less incrassate 

 distally. 



Acrotona malaca n. sp. Parallel, shining, moderately convex, rather 

 sparsely punctate and not as densely so as usual even on the elytra, pale 

 piceo-testaceous in color, the elytra not paler, the head darker piceous and 

 the abdomen with a large feeble and indefinite subapical piceous cloud; 

 head rather small, suborbicular, a little wider than long, not inflated basally, 

 the eyes as usual; antennae moderately long, pale, gradually and evidently 

 incrassate and somewhat less pale distally, of the usual structure in the pre- 

 ceding species, the subapical joints evidently wider than long; prothorax 

 large, transverse, unusually parallel and with only very moderately arcuate 

 sides, the apex but very little narrower than the base, much wider than the 

 head and exactly equal in width to the elytra, the rounded basal impression 

 minute and obsolescent; elytra rather short and transverse, subparallel, 

 the suture not quite so long as the prothorax; abdomen broad, at base as 

 wide as the elytra, very feebly tapering and with markedly arcuate sides 

 thence to the apex. Length 2.0 mm.; width 0.5 mm. California (Siskiyou 

 Co.). 



There is no species with which this can be closely compared; the 

 pale coloration distinguishes it from any other and the indications 

 are that this paleness is not due to immaturity to any considerable 

 degree. 



Eurypronota Csy. 



This, as heretofore stated (Can. Ent., XLII, p. 107), is properly 

 a stibgenus of Acrotona; the type, Acrotona (Eurypronota) discreta 

 Csy., differs greatly in general form, however, from any true 

 Acrotona and the antennae are larger and heavier. 



Engamota n. subgen. 



The true affinity of this genus or subgenus is doubtful, but I 

 will dispose of it at present at a subgenus of Acrotona, as the general 

 form and sober coloration of the body harmonize very well with 

 Acrotona, and the strongly inflexed hypomera are invisible from the 

 sides, but there the resemblance largely ceases. The middle coxae
