STAPHYLINID.E 47 



7 Form moderately stout, rather convex, shining, evenly dark red-brown 

 in color, the head black; legs piceous, the antennae blackish, not pale 

 at base; head large, orbicular, five-sixths as wide as the prothorax, 

 the eyes large and prominent, at less than a third their length from 

 the constriction, the frontal impressions much more widely separated 

 than in any of the preceding species, subpunctiform; antennae rather 

 slender, the outer joints fully as long as wide, the second and third 

 equal and together not distinctly longer than the first; prothorax 

 orbicular, barely wider than long, strongly arcuate at the sides and 

 base, the three dorsal punctures deep, in straight line; elytra scarcely 

 as long as wide, everywhere narrower than the prothorax, finely, 

 rather closely punctate, the punctures asperulate; abdomen gradu- 

 ally tapering, finely, very evenly punctate, the punctures widely 

 separated, rather more so than those of the elytra; sixth ventral 

 (cf ) with a distinct rounded sinus about three times as wide as deep, 

 the adjoining surface feebly impressed for a short distance; hind 

 tarsi slender, distinctly shorter than the tibiae. Length (cf) 4.5 

 mm.; width 0.9 mm. British Columbia (Inverness), Keen. 



oculeus n. sp. 



Form slightly stouter, a little larger in size, the type pale tawny-testaceous 

 throughout, the head black; legs pale; antennae notably slender, 

 rather longer than the head and prothorax, all the joints longer than 

 wide, pale brown, blackish basally; head orbicular, three-fourths 

 as wide as the prothorax, the eyes very large, at less than a third their 

 length from the constriction, the posterior puncture very close to 

 their inner margin; frontal impressions large, shallow and rather 

 indefinite; prothorax subquadrate-orbicular, about as long as wide, 

 the parallel sides evenly and strongly arcuate, the punctures as in 

 oculeus; elytra shorter than wide, as long as the prothorax and, 

 apically, somewhat wider, the punctures rather strong, subasperate 

 and close-set; abdomen barely visibly tapering, the punctures moder- 

 ate, evenly distributed, asperulate and much more widely separated 

 than those of the elytra; sixth ventral (cf ) with an apical sinus nearly 

 as in the preceding but more angular; hind tarsi slender. Length 

 (cf) 5-5 mm.; width 1.25 mm. California (a single specimen, with- 

 out more definite record of locality) sparsus n. sp. 



Agnatus without doubt closely resembles cenescens Makl.,* from 

 the Island of Sitka, but according to the description given by 

 Mannerheim, the elytra are much more closely punctate in that 

 species and the sides are rufescent, a character not observable in 

 agnatus. If virginicus was known to Dr. Horn, I am at a loss to 

 know how he disposed of it; the head is so notably small that the 

 general aspect of the species is peculiar; the second and third 

 antennal joints are subequal and together about as long as the first. 



* This species was properly included in Dr. Horn's table of Quedius species, but he 

 gave no description of it in the text.
