(Indian Mus. Notes, V, p. 134). In general the larvae are either semi- 
aquatic, living on the leaves of aquatic plants in cases made of their 
own excrement, or live on plants on land in the same way. These 
larvae have the anus on the upper surface so that as their excrement 
U voided, it covers the body and makes a protective covering. They 
are extremely characteristic in appearance and are likely to be found 
on aquatic plants. The beetles are common in grass and on plants; 
they are usually brightly coloured and warning; several species are 
common, Lema coromandeliana , F., and Crioceris impressa , F., being 
widely spread in the plains. 
Camptosomes. —A large division divided into several sub-families, 
some of which are not represented in India. The Clytrince , Chlamynce 
and Cryptocephalince , are the most common, with many species of small 
cylindrical beetles, coloured often in orange or yellow and black. The 
larvae of Cryptocephalus are of peculiar form and live in small cases 
formed of their excrement ; they are white larvae, with the abdomen 
tapering and doubled back under the body so that the apex reaches 
the thoracic legs ; the case made is a small oval one, in which the larva 
lives with the head and thorax at the opening, the anus in such a posi¬ 
tion that the excreta can be ejected. (In a Himalayan species living
