464 CHRYSOMELID2E. 



This genus differs from Acroihinium and Lophea in the very 

 broadly dilated apical joints of the antennae, the more dense 

 pubescence which consists of short and long hairs, the dentate 

 femora and prosternal grooves.

 1874, p. 317, note 1. 



Black ; elytra golden cupreous ; the suture and a broad angulate 

 band placed near base and sides bluish-black. 



Head closely rugosely punctured and finely pubescent. Thorax 

 closely but not rugosely punctate and pubescent. Elytra punctured 

 like the thorax and with silvery short and longer suberect black 

 pubescence ; the bluish band placed below base, very broad and 

 extending at right-angles downwards to behind the middle, rest 

 of surface cupreous. Body beneath closely and finely punctured. 



Length 6 mm.

Genus EURYPELTA.

Type, E. modesta, Fabr. 



Range. India. 



Subquadrate-ovate. Antennae subfiliform, about half the length 

 of the body, basal joint thickened, second half as long as the 

 third, the latter slightly longer than the fourth, terminal joints 

 slightly widened, much longer than broad. Thorax transverse, 

 wider at middle than at the sides, latter nearly straight, angles 

 acute. Scutellum broader than long. Elytra much broader at 

 base than the thorax, irregularly punctured, each puncture with a 

 minute hair. Prosternum narrowed between the coxae. Legs 

 unarmed, tibiae entire, first joint of tarsi slightly or not longer 

 than the second ; claws appendiculate. 



The pubescence of the upper surface in this genus is so short 

 as to be easily overlooked. The scutellum and the prosternum 

 are of a different shape to those in the preceding genera, to which 

 Eurypelta is, however, closely related.
