MALACODERMIDiE. 
323 
In India the Lampyride division of this family includes the only 
luminous insects ; the only other light-emitting insects in which the 
light is the direct production of the insect’s tissues are the species of 
Pyrophorus (Elateridce), which are confined to the Neotropical Region. 
This large family is divided into sub-families (tribes) as follows :— 
\ Antennae inserted on the frons 
or at the base of the rostrum 
dorsally. 
(a) Intermediate coxae separated. 
(b) ,, ,, contiguous, 
antennae sub-contiguous. 
Antennae distant. 
II, Antennae inserted laterally in front 
of the eyes. 
(a) Clypeus not distinct. 
(b) Clypeus separated by a suture.

Lycince .—Over fifty species are recorded from India, largely from 
hill forest localities. Red and 
THQRACICUS. 
orange are prevailing colours in our 
species ; the beautiful Lycostomus 
prceustus, Fabr., is found in the plains, 
a deep orange insect with the elytra 
tipped with black. We have seen 
bushes so clustered with red Lycos¬ 
tomus as to appear to be covered with 
red blossoms. L. rufiventris, Wat., is 
another of our species, the colouring 
bright red ; it rests by day openly on 
a plant or grass stem, and is active 
at night only. 
Lampyrince are monographed by E. 
Olivier in Genera Insectorum (1907). 
Indian species are as follows :— 
Lucidotini .. .. Lucernuta 9. 
Lamprophorini .. .. Lamprophorus 10. 
Diaphanes 17. 
Lampyris 1.
