new species of Staphylinidae from India. 533 
Head a little broader than the thorax, not so broad as the elytra, 
impressed on either side of the front, elevated in the centre, coarsely 
punctured all over without any smooth space. Antennae rather 
short, Ist and 2nd joints of equal length, 3rd to 7th longer than 
broad, gradually decreasing in length, 8th but little longer than 
broad, 9th to 11th forming a club. Thorax convex, a little longer 
than broad, widest at the middle, sides rounded and equally nar- 
rowed in front and behind; puncturation, coarse, close and rugose, 
more or less transversely confluent on the disc, without depressions. 
Elytra ample, very slightly broader than long and about as long 
as the thorax, puncturation as coarse as on the latter, but not 
confluent. Abdomen distinctly pointed, the first three visible 
segments each with three distinct keels, one median and one on 
either side, the fourth with a single median keel; bases of the 
segments closely, but much more finely punctured than the fore- 
parts, the apices yet more finely and sparingly punctured ; pubescence 
grey, scanty.

13. Dianous versicolor, n. sp. 
Bronze-black, shining, with distinct greenish-violet iridescence, 
especially on the head and abdomen. Legs, palpi and antennae 
(except last three joints which are dirty testaceous), black. Length 
6 mm. 
Head with the eyes broader than the thorax, not so broad as 
the elytra; bronze-green with a sheen like satin especially on the 
vertex, more opaque and blacker anteriorly, densely and finely punc- 
tured. Antennae black, the last three joints dirty testaceous, 2nd 
joint shorter than the Ist and 3rd, the latter very long, the following 
gradually decreasing in length. Thorax shining bronze with distinct 
green reflex, shining (but without the satiny gloss seen on the head), 
a little longer than broad, the sides dilated and rounded before the 
middle, narrowed and parallel behind, strongly impressed on either 
side at the widest part and before the base in such a manner as 
to form on either side a distinct reniform callus with the concavity 
inwards; exceedingly sparingly, scarcely perceptibly punctured, 
but with a fine coriaceous ground sculpture; glabrous. Zlytra 
much longer than the thorax, uneven, strongly impressed behind 
the shoulders, on either side of the suture and less distinctly before 
the postero-external angles; bronze-green like the head, densely 
and finely punctured, finely pubescent. Abdomen iridescent,
