vated in the middle, are likewise black, with irre- 
gular bands formed of yellow confluent spots ; two 
of these spots, one on the shoulder of each elytron, 
and another at the apex, are reddish ; the surface is 
marked with dark impressed points, which form ir- 
regular lines anteriorly. The under side and legs 
are black. The markings vary much, in some in- 
stances the black bands on the elytra being almost 
obliterated.

This genus was established by Mr Kirby on an 
insect from Brazil, very closely related to Helops. 
The head and thorax are black and shining, the latter 
sparingly punctured. The elytra are very gibbous 
in the centre, marked with punctured lines, of a 
pale-yellow colour spotted with black, and having a 
broad band over the middle, and the apex black. 
The under side and legs are likewise black. The 
figure of this insect has been accidentally placed 
among the tetramerous insects, but it belongs to the 
heteromerous section, as will be seen from the num- 
ber of joints in the tarsi.
