757. Demotina thoracica, Jac. 1\ Z. S. 1887, p. 70. 
Greyish-fuscous, closely pubescent ; the apices of the tibiae 
fulvous ; thorax strongly rounded at the middle, obscurely marked 
with brownish bands ; elytra covered with light grey pubescence, 
a spot at the base and two rows of similar spots placed transversely 
behind the middle, fuscous. 
Head closely punctured, covered with light grey pubescence, 
which is interrupted on the vertex by two more or less distinct 
longitudinal brownish bands ; the anterior margin of the cl v pens 
and the labrum fulvous, glabrous ; antennae half the length of the 
body, slender, the terminal joints slightly thickened, the third and 
fourth joints equal, all the joints pieeous or dark fuscous. Thorax 
transverse, strongly rounded and widened in the middle ; the 
entire surface covered with whitish-grey pubescence, which 
assumes the shape of a longitudinal band at the sides ; the latter 
with a round depression. Scutellum greyish-pubescent. Elytra 
finely punctate-striate, clothed with greyish pubescence like the 
thorax ; at the basal margin are two more or less distinct fuscous 
or dark brown spot s, bounded at the sides by whitish bands ; 
behind the middle are placed two transverse rows of similar 
spots. All the femora are armed each with a strong tooth; the 
sides of the elytra are furnished with short and stiff bristles. 
Length 3-4 mm. 
Hob. Ceylon : Dikoya. 
The thorax in the present species is much narrowed in front 
and at the base, giving more prominence to the middle ; the 
pubescence of the upper surface is generally whitish-grey, but 
sometimes of a more fulvous tint, and the fuscous spots are more 
or less distinct ; in well-marked specimens they are often preceded 
by whitish spots, caused by the thickening of the pubescence in 
those places ; in some specimens there are three oblique rows of 
obscure spots on each elytron besides those at the base, which 
latter are generally present.
