COLEOPTERA. CHRYSOMELIDiE. 385 



The third, and last, flimily, Chrysomelid.^* Leach, is distinguished 

 by having the antenna; inserted \videl3' apart at the base before the 

 eyes, or near their inner extremity. The body is generally of an 

 hemispherical or ovate form, the base of the thorax being as broad as 

 the shoulders of the elytra ; the legs are of equal size, and not formed 

 for leaping ; the antennae are short, and slightly thickened towards the 

 tips ; the mandibles {^jig. 48. 6.) are notched at the extremity, and 

 the palpi are short {fig. 48. 7, 8.). 



These insects, which are herbivorous in the larva and perfect states, 

 are often ornamented with the most brilliant colours, amongst which 

 blue, green, and gold are preeminently conspicuous ; and, as is usually 

 the case in metallic- coloured insects, the variation of colour in the 

 same species is often very great. Their motions are very slow, their 

 broad tarsi giving them a firm hold on the leaves upon which they 

 reside. The larvte are hexapod, and furnished with an anal proleg, 

 serving as a seventh leg, and emitting a glutinous secretion, by which 

 the larvae attach themselves to the leaves when about to undergo their 

 transformations ; some species, however, descend to the earth. The 

 larvas of the genus Clythra, as observed by M. Wandouer, and com- 

 municated to Latreille, inhabit hairy cases, of a leathery-like matter, 

 which they drag about with them, protruding the head from the
