STAPHYLINID^E. 41 



Oxypoda paganica n. sp. Stout, rather convex, tapering behind, 

 slightly shining, pale piceous-brown, the head slightly darker, the ab- 

 domen blackish except apically; punctures very fine throughout, not 

 dense except on the abdomen, the vestiture distinct, palish, not dense 

 anteriorly; head scarcely more than half as wide as the prothorax, fully 

 as long as wide, parallel and rounded at the sides, the eyes at nearly their 

 own length from the base; antennae short, rather pale throughout, 

 gradually distinctly incrassate distally, of the usual structure, the outer 

 joints rather strongly transverse, the last obtusely ogival at tip and 

 longer than the two preceding; prothorax large and convex, one-half 

 wider than long, widest at about the base, the sides evenly arcuate, 

 gradually strongly converging anteriorly, the base broadly arcuate; 

 elytra well developed, very moderately transverse, parallel, as wide as the 

 prothorax, the suture equal in length to the latter, the apical sinuses 

 notably deep; abdomen at base scarcely narrower than the elytra, gradu- 

 ally rather strongly tapering and with nearly straight sides thence to the 

 fifth tergite, which is three-fifths as wide as the base and transverse; 

 margins not thick. Length 1.8 mm.; width 0.6 mm. California (Po- 

 mona Mts., Los Angeles Co.), Fall. 



To be known readily by its stout and posteriorly tapering form, 

 coloration, well developed elytra, oval and narrow head and other 

 characters. 



Oxypoda nutricia n. sp. Nearly as in the preceding though a little 

 less stout and darker in color, very dark blackish-brown, the legs and 

 antennae paler, the sculpture of the anterior somites, and especially the 

 pronotum, notably coarser and rougher; head distinctly wider than long 

 and evidently more than half as wide as the prothorax, the antennae 

 nearly similar, the second joint almost as long as the next two combined, 

 fourth fully as long as wide; prothorax and elytra throughout almost as in 

 paganica, the former a little less, the latter rather more, transverse, with 

 the suture somewhat shorter than the pronotum; abdomen similar 

 throughout though with thicker side margins. Length 1.6 mm.; width 

 0.5 mm. California (Sta. Cruz Mts.), Harford. 



Very close to the preceding and perhaps only a subspecies, but it 

 is not so stout, darker in coloration, more coarsely sculptured and 

 has a larger and notably more transverse head. In both the hind 

 tarsi are very long and slender, with the much elongated first joint 

 not quite equal to the next three. 



Group IV. 



The only distinguishing feature of this group, when compared 

 with the preceding, is the greater development of the elytra and 

 corresponding diminution of the prothorax, so that the sides of
