COLEOPTERA. 
hairs on each side. These wings fold under the elytra. These little 
beetles are found amongst decaying vegetable matter and under the 
bark of trees ; most are shining brown and are apt to be passed by on 
account of their small size. They are often found in numbers together. 
No Indian species appear to have been reared. The larvae of the known 
species are stated to be active and predaceous on small insects. Pteni- 
dium macrocephalum, Nietn., with several Ceylon species is recorded. 
CoRYLOPHIDiE. 
Very small beetles, the antennae of peculiar form, six free abdominal 
segments, tarsi apparently three-jointed. 
Like the Trichopterygidce, many of these small beetles have fringed 
wings. Eleven species are known from Ceylon and one from Burmah. 
SCAPHIDIIDJE. 
Abdomen with six or seven visible ventral segments, the basal ventral 
segment large. Tarsi of five joints. Elytra truncate, with two 
longitudinal striae, with raised points between. Antennae with the five 
apical joints broadened. 
These small beetles are found in mushrooms and beneath stones. 
They are recognisable only from careful examination of the whole 
characters. The antennae are but slightly clubbed. The truncate 
elytra expose only the apex of the abdomen. The wings are well 
developed and the beetles are active. The apex of the abdomen 
as seen from below is conical and rather long. Only a few genera 
are known and these are widespread. Scaphidium conjunctum 
Motsch., S. lunatum, Motsch. and S. cyanellum, Obart, are recorded 
as Indian with several Ceylon species. 
Histerim. 
Elytra usually truncate. Integument hard, body compact. Antennce 
of one long basal joint, a number of small joints(7), and an apical 
club of three joints. 
These small hard beetles are generally recognisable at sight from 
their general build and the above characters. Nearly all are black or
