silky hairs, and their elytra are marked with rows of deep punctures. The larvae 
feed under water upon the roots of the plants, and change to pupae which are 
1, Lamia textor • 2, Female of A. cedilis ; 3, Male of Acathocinus cedilis ; 4, Saperda carcharias ; 
5, S. populnea. (All nat. size.) 
enclosed in oval cocoons. In the beetles of the section Camptosomata, the body is 
short, the head vertical and deeply sunk in the prothorax, and the abdomen slightly 
curved, with its middle segments con¬ 
tracted ; the antennae are short and serrate 
or pectinate in the first subfamily, while 
in the second they are rather long and 
filiform. The larvae move about sur¬ 
rounded by a sack-like case, from which 
the head and anterior part of the body are 
free. They retract themselves completely 
within the case and close up the opening 
when about to undergo their metamor¬ 
phosis. The Cyclica comprise four sub¬ 
families, of which the first, the Eumolpince, 
is almost entirely composed of exotic 
species, though one of the few species 
found in Europe (Bromius vitis) is only 
too well-known on account of the damage 
it inflicts on the leaves of the vine. With 
the Chrysomelince we come to the most 
typical forms belonging to the family. 
These beetles are distinguished by their oval and convex shapes, having in many 
cases a great resemblance to lady - birds ( Coccinellidce ), while their colours are 
Donacia clavipes, with larva and pupa case 
(nat. size).
