new species of Staphylinidae from India. 531 
the puncturation is much stronger and closer. Antennae moder- 
ately long, all the joints longer than broad, the last three 
forming a club. Thorax about a third longer than broad, broadest 
at the middle, sides slightly rounded and equally narrowed 
in front and behind, rather coarsely and closely punctured : 
pubescence whitish, moderate. Hlytra ample as long as the thorax 
and as broad as long, similarly punctured to the thorax. Abdomen 
gradually narrowed posteriorly, margined, first four visible segments 
with a median keel, puncturation fine and close on the basal parts 
of the segments, much finer and more sparing on the apical parts : 
pubescence whitish, rather distinct. 
3g: Unknown.

10. Stenus (Hypostenus) nitidulus, n. sp. 
Black, shining, elongate; head carinate; thorax almost cylin- 
drical, much narrower than the head ; elytra ample, as long as broad ; 
fore-parts moderately, coarsely, and closely punctured. Abdomen 
cylindrical, not margined, less coarsely and closely punctured than 
the fore-parts. Antennae, palpi and legs testaceous, the club of 
the former scarcely infuscate. Fourth joint of the tarsi bilobed. 
Length 4 mm. 
At first sight this species is not unlike S. bispinus, Mots, but 
the head is broader and the thorax narrower, the puncturation 
of the fore-parts is, however, very similar, but that of the abdomen 
is very much coarser. 
Head much broader than the thorax, as broad as the elytra, with 
a smooth elevated central space, depressed on either side, rather 
coarsely and closely punctured. Antennae long and slender, Ist 
and 2nd joints of equal length, 3rd to 8th very long and slender, 
gradually decreasing in length, 9th to 11th forming a slender club. 
Thorax narrow, almost cylindrical when viewed from above, very 
slightly and equally narrowed in front and behind, one-third longer 
than broad, rather coarsely and closely punctured, sometimes with 
a smooth space in the middle of the disc. Hlytra as long as the 
thorax, as broad as long, sometimes slightly impressed behind the 
shoulders, punctured similarly to the thorax. Abdomen cylindrical, 
the segments constricted at the bases, puncturation finer and less 
close than on the fore-parts, especially behind. Pubescence scanty, 
greyish. Anal spines wanting. 
¢ : Last ventral segment with deep excision, the apex of which is 
rounded.
