MALACODERMIDiE. 
319 
beetle is said to knock with its head in the tunnels, as a signal presum¬ 
ably to others of its kind. This is a cosmopolitan insect and is common 
in books in this country. Lasioderma testacea , Duft. (Plate XIX), 
is slightly broader but otherwise similar in appearance, pubescent brown 
with five lines on the elytra. It bores in cheroots and cigarettes, the 
larva also boring in the same place. This insect is a serious pest in cured 
tobacco and any form is liable to become infested. The larva pupates 
in a case in the tobacco or between the cheroots and the life-history is 
a short one. It is recorded as attacking opium in the Gazipur Factory 
(Indian Mus. Notes, I, p. 57) and is a well-known insect in South Indian 
tobacco factories. It may also be found in turmeric and probably 
other drugs sold in the bazaars. In addition to the above household 
species, nine species have been described from this country. No 
details of the lives of these free-living species are available. 
MALACODBRMATA 
This group may be divided as follows :— 
Lycidce. 
Here treated as Malacodermidce. 
Lampyridce. 
Telephoridce (Cantharidce). 
Drilidce , 
Melyridce. ( Malachiidce .) 
Cleridce. 
Lymexylonidce. 
Rhagophthalmidce. 
Amongst important recent papers are Gorham’s on the Andrewes 
collection (Ann. Soc. Ent. Beige, 1895, p. 294 ; 1903, p. 323 ; Proc. 
Zook Soc., London, 1889, p. 96) and Bourgeois’ papers (Ann. Soc. Ent. 
Beige, 1892, p. 7 ; 1905, p. 46 ; 1906, p. 99 ; 1891, CXXXYII ; Bull. 
Soc. Ent. France, 1896, p. 117 ; Ann. Soc. Ent. France, 1903, p. 
478; 1905, p. 127). For Lycidce, Waterhouse’s Illustrations of Typical 
Coleoptera, Vol. I, is valuable and the Lampyridce are listed by Olivier 
in Genera Insectorum. 
Malacodermidw. 
Tarsi five-jointed. Integument soft. Six , 
seven or eight ventral segments. 
This family is a large assemblage of forms which are difficult to 
define accurately but which are, as a general rule, easily recognised.
