COLEOPTERA— STAPHYLINIDiE. 505 



Bledius glaciatus. 

 PJ. 1, Fig. 35. 



Allied to B. brevidens LeC. A single elytron, about twice as long as 

 broad, the sides almost parallel and straight, slightly broader than elsewhere 

 just before the tip, the apical margin straight, not inclined, the outer poste- 

 rior angle gently rounded, the outer border slightly, the inner scarcely, 

 margined, the deflexed portion of the outer margin narrow, equal, termi- 

 nating at the middle of the outer half Texture delicate, the surface 

 slightly, irregularly, and not very closely punctate. A very small and 

 rather broad scutellum is indicated by the shape of the inner basal angle, 

 which is not quite accuratel}^ given on the plate. 



Length of elytron, 1.9™™; breadth, 1.1™".

OXYPORUS Fabricius. 



OXYPORUS STIRIACUS. 

 PI. 1, Fig. 36. 



A single elytron, less than twice as long as broad, somewhat broken at 

 the base, with very straight and almost parallel sides, enlarging to the least 

 possible degree apically. It is a rather small species, of delicate texture, 

 with smooth, unsculptured surface, except for the slightly impressed lines 

 wliich follow the sutural and outer margins, giving a thickened appearance 

 to either edge. The outer margin is gently and regularly convex, the outer 

 posterior angle gently rounded, and the deflexed portion of the outer mar- 

 gin very narrow, equal, and reaching as far as the rounded apical part. 



Length of elytron, 1.8™"'; breadth, 1.12™™.
