Raffray has catalogued the known species (Ann. Soc. Ent. France- 
1903-1904, and Genera Insectorum, 1907). 
and one Clavigerine as occurring “ in India,” 
the majority having been found in Ceylon 
and Burma. (No less than sixty additional 
Indian species are characterised by Raffray 
as 4 4 species mentioned by Motschoulsky 
but not “described;” these are included 
in Atkinson’s catalogue but are not valid 
species). Raffray has since described nine 
species from the Nilgiris and Belgaum (Ann. 
Soc. Ent. Beige, 52, 205). We have found 
one species in an ant’s nest (Myrmecocystus 
setipes) in Behar; the only known Indian 
Clavigerine beetle is Mastiger abruptus, 
Mots., described as from Calcutta. 
He lists 53 Pselaphines

Staphylinid^. —Rove Beetles. 
The elytra truncate and covering only the base of the abdomen, which 
is long with ten dorsal and at least seven visible ventral segments. 
Tarsi variable, three, four or five-jointed. 
In this family are small beetles, rarely exceeding one-quarter of an 
inch in length, usually recognisable in the field from all but Nitidulidce. 
The colours are usually sombre, browns and blacks as in most surface 
insects, while a few which live openly on plants exhibit a brighter 
colouring [e.g., Pcederus). 
The antennse are of moderate length, simple, the head large with 
short biting trophi ; the prothorax is distinct, the sides of the body 
more or less parallel and the abdomen long, tapering and flexible. The 
large folded wings are concealed under the small truncate elytra, which 
meet in a straight line in the middle over the base of the abdomen. 
The legs are short, formed for rapid running ; the tarsi are often 
three-join ted, in some four or five-join ted throughout, and in a number 
the fore tarsi are four-jointed, the posterior tarsi with five pairs of joints. 
The integument is less thickened and hardened than in most beetles, 
the abdominal segments are mobile and readily turn up, suggesting the
