STAPHYLINID^E. 189 



elytra, parallel, with feebly arcuate sides, the basal angles well rounded; 

 eyes small, anterior; antennae moderate, feebly enlarged distally; gular 

 sutures fine, rather close, most approximate at the middle, thence just visibly 

 diverging to the base, the under surface finely and sparsely punctate; pro- 

 thorax slightly narrower than the head, evidently wider than long, a little 

 narrower at base than at apex; elytra parallel, perhaps slightly longer than 

 wide; abdomen a little narrower than the elytra. Length 4.3 mm. ; width 

 0.7 mm. Colorado (Boulder Co.). 



The single type represents a species allied to inquilinum and 

 nitidulum, but having the sides of the head more arcuate and its 

 under surface more finely and rather sparsely punctured ; it is also 

 a female and the male of this particular group seems to be very 

 rare; I have not been able to find one among my material. 



Paramedon Csy. 



Paramedon pallidipenne n. sp.- Rather stout, black or piceous-black, 

 the entire elytra pale flavo-testaceous, the abdominal tip also pale; antennae 

 inf innate toward the base of the funicle; integuments rather shining; head 

 well developed, parallel, finely, not densely punctate, the gular sutures fine, 

 separated by about the thickness of the third palpal joint; eyes at between 

 two and three times their length from the base, the basal angles well rounded; 

 prothorax obtrapezoidal, distinctly wider than long, similarly loosely but still 

 more finely punctate; elytra distinctly elongate, parallel, slightly wider than 

 the head, finely but strongly, densely punctate; abdomen finely, densely 

 punctulate, narrower than the elytra, narrowed apically, the fifth ventral 

 (cf ) with the median smooth lobe evidently wider than the lateral fringes 

 and with its apex broadly, parabolically sinuate. Length 3.5-3.8 mm.; 

 width 0.78 mm. California (Mohawk), Fenyes. 



Differs from montanum, boreale and tahoense in its relatively 

 smaller prothorax and longer, more strongly punctate and paler 

 elytra. 



Paramedon oriens n. sp. Moderately slender, pale flavo-testaceous 

 throughout, slightly shining; head moderate, parallel, with rounded basal 

 angles, finely and strongly but not densely punctate, with a few larger punc- 

 tures widely scattered, the gular sutures rather fine, separated by scarcely 

 one-half the thickness of the third palpal joint; prothorax barely as wide 

 as the head, feebly obtrapezoidal, a little wider than long, finely, not closely 

 punctate, rather more convex along the median line; elytra parallel, evi- 

 dently longer than wide, slightly though obviously wider than the head, 

 finely, closely punctate; abdomen rather wider than the head, alutaceous, 

 minutely and closely punctulate. Length 4.0 mm.; width 0.68 mm. New 

 Mexico (Albuquerque). 



The single female type represents a species somewhat resembling 

 arizonicum, but much narrower in form and with slightly less
