silky hairs, and their elytra are marked with rows of deep punctures. The larvaa 

 feed under water upon the roots of the plants, and change to pupse which are

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).
