CHRYSOMELID-ffi. 
This genus differs from Acrothinium 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.

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.

Type, if. moclesta, Eabr. 
Lange. 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.
