STAPHYLINID^E. 191 



shining though finely and closely punctate; abdomen much narrower than 

 the elytra, minutely and closely punctulate but not dull in lustre. Length 

 2.4 mm.; width 0.26 mm. Utah (Nephi), Wickham. 



Represented by a single female. 



Pseudorus prolixipennis n. sp. Still more slender, moderately convex, 

 shining, deep black throughout, the legs and antennae piceous; head narrower 

 but otherwise nearly as in spectralis, the eyes somewhat smaller, the surface 

 polished, minutely, not closely punctate; prothorax elongate, much narrower 

 than the head, the rounded anterior angles well before apical third, the sides 

 subparallel, the polished surface very minutely and not closely punctulate; 

 elytra very elongate, parallel, two-fifths longer than wide, much wider than 

 the head and very much wider and longer than the prothorax, shining, very 

 finely though somewhat closely punctulate; abdomen much narrower than 

 the elytra, the fifth ventral (c?) unmodified, the sixth with a rounded 

 median sinus which is much wider than deep and gradually formed at the 

 middle of the apex. Length 1.9 mm.; width 0.22 mm. California (St. 

 Helena, Xapa Co.). Attracted to the electric lights. 



The three examples before me show that prolixipennis, though 

 similar in general organization and likewise very small and slender, 

 differs from spectralis in its narrower head, more anterior and less 

 broadly rounded anterior angles of the prothorax, as well as in 

 some details of sculpture and other features. Both of these species 

 are very much smaller and more slender than cervicula. 



Stilicopsis Schse. 



Stilicopsis subtropica n. sp. Form, color and nature of the sculpture nearly 

 as in paradoxa but a little smaller, more slender and less strongly and more 

 sparsely punctured, the head relatively somewhat larger, being much wider 

 than the elytra and with the eyes markedly larger, being at but little more 

 than their own length from the base ( 9 ) ; prothorax relatively smaller, less 

 orbicular and somewhat obtrapezoidal but with all the angles broadly 

 rounded; elytra narrower, not transverse but almost as long as wide, the 

 sides less rapidly diverging from the base; abdomen more feebly and nota- 

 bly more sparsely sculptured. Length 2.4 mm.; width 0.45 mm. Florida. 



The single type evidently represents a species different from 

 paradoxa, to be readily separated by the narrower and more parallel 

 elytra, sparser sculpture and larger eyes, among other characters. 

 I found paradoxa in abundance near St. Louis, Mo., during the 

 latter part of 1905; it also occurs in the southern Atlantic coast 

 regions.
