longitudinal elevated line of red down the middle of 
each, which is turned backwards at the base. The 
under side of the body, and the legs, are black. 
An inhabitant of the same countries as the pre- 
ceding species, and often found in company with it.

This species is liable to considerable variation 
both in size and markings. The head and antennae 
are black, and the former has an angular projection 
on each side anteriorly. The thorax is rather long 
and narrow, and is produced on each side before the 
middle into an acute angle: the colour is yellow, 
with a broad streak of black down the centre ; and 
occasionally there is a rounded spot of black placed 
between the dorsal line and the lateral projections. 
The scutellum is black. The elytra are reddish 
yellow, with a broad band of black on each side, and 
another along the suture, which meet at the apex, 
and gradually become narrower at the opposite ex- 
tremity, scarcely extending to the base. The legs 
and under side of the abdomen are reddish yellow, 
the latter with two longitudinal streaks of black. 
Likewise a native of South America, where it ap- 
pears to be pretty common.
