Family PSELAPHIDA2. 
Catalogue of the Inseeta of the Oriental Region, No. 11. Order Coleoptera, 
Family Psiclaphid.-e. — By E. T. Atkinson, B. A. 
Leconte describes the Pselaphidee as comprising a number of very small 
insects, not exceeding one-eighth of an inch in length, of a chestnut-brown 
colour, usually slightly pubescent : the head and thorax are most frequent- 
ly narrower than the elytra and the abdomen, the latter is convex, and 
usually obtuse at the apex. Many are fouud flying at twilight, others in ants’ 
nests, or under stones or bark. The general form is that of the Scydmae- 
nidce from which the Pselaphidce are distinguished by the truncate, short 
elytra that leave a part of the abdomen exposed, and the narrow, transverse, 
usually not contiguous, posterior cox®. Dr. L. W. Schaufuss 1 distributed 
the genera into six groups arranged according to the number of the anten- 
nal joints: — Articerides, Adranides, GoniaUides, Clavigerides, Cyalhigerides 
and Pselaphides. This arrangement was reviewed by Dr. E. Reitter, 2 * in 
1882, who formed five sub-families, Ctenislini, Batrisini, Bryaxini , Psela- 
phini and Eupleclini, Leconte & Horn, 8 give two sub-families, (Ttavigerinoc 
and Pselaphincn, the latter of which is again sub-divided into groups.
