STAPHYLINID^E 441 



teriorly, the serial punctures rather strong; scutellum moderate; elytra 

 much shorter than the prothorax, at base distinctly wider than the latter 

 and at apex still wider, not quite as long as wide; punctures rather coarse 

 and widely separated, the ground polished; abdomen gradually, arcuately 

 narrowing posteriorly, polished, finely and sparsely punctate; sixth ventral 

 (d 71 ) elongate and rather attenuate, the entire apex occupied by an emar- 

 gination twice as wide as deep, which is exactly triangular, with perfectly 

 straight sides and sharp angle, the edges with a very steep bevel, the 

 upper edge of which is loosely fimbriate, the fifth segment not modified; 

 anterior tarsi very slender. Length (d") 7.0 mm.; width 1.2 mm. 

 California (Sta. Cruz Mts. and at San Francisco). 



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

 elytra being relatively shorter than in albionicus and the other 

 species mentioned above; the surface has a peculiar varnish-like 

 gloss throughout; the elytral punctures are decidedly coarse and 

 the elytra are more rufous than the other parts. 



The following seven species belong to Section E of Horn, the 

 thoracic punctures being numerous and irregular; the body is 

 generally of rather large size: 



Philonthus morosus n. sp. Stout, shining, black, the anterior parts 

 senescent, the elytra more strongly; legs nearly black; antennae deep black 

 throughout, stout, nearly as long as the head and prothorax, incrassate; 

 outer joints slightly wider than long; head quadrate, with many coarse 

 punctures, which become sparse or are wanting broadly at the middle; 

 eyes very large, convex, at three-fifths their length from the base, the 

 tempora short and strongly tumid laterally, being more prominent than 

 the eyes; prothorax slightly wider than long and very little wider than 

 the head, the parallel sides broadly and obtusely prominent at the middle, 

 the base arcuate, the angles rounded but not obliterated; punctures 

 moderate, evenly but sparsely distributed ; abroad, clearly defined median 

 line impunctate; elytra quadrate, slightly longer and wider than the 

 prothorax, closely and moderately strongly punctate; abdomen parallel, 

 rounding at apex, finely but strongly, evenly and not closely punctate; 

 sixth ventral (d 71 ) with a broad shallow cuspidiform sinus at tip, the 

 adjacent surface not modified, the fifth segment normal; anterior tarsi 

 moderately broadly dilated. Length (cf 9 ) 9.0-10.5 mm.; width 2.1-2.2 

 mm. California (Lake and San Francisco Cos.). 



Related somewhat to lecontei but very distinct in its larger and 

 more punctate head, with larger eyes and prominent tempora, 

 more numerous thoracic punctures, in the very simple male sexual 

 characters at the abdominal apex and in the much less broadly 

 dilated anterior tarsi. The elytra sometimes become obscure 

 rufous, with a large sutural blackish cloud basally, as is the case in 

 most of the species of this particular group of Section E. I have
