has the closest affinity with IViinotracjus , The middle 
sockets are widely open externally and the mesosternmn

1. Erythroplatys corallifer. 
White^ Cat. Longic. Brit. Mus. p. 202^ pi. v. f. 2. 
The figure here quoted will give an accurate idea of 
this singular insect^ which by reason of its widely-dilated 
elytra^ coarse sculpture^ and bright red and black colours, 
becomes the mimetic analogue of Cephalodonta spinipesj 
Fabr., of the family Hispidee. It is not found, however, 
in company with that insect. At least, the few examples I 
met with were found on the flowers of a low tree, named 
Pitomba, in the neighbourhood of Santarem, whilst the 
Cephalodonta was seen only on the foliage of a climbing 
plant, generally in great numbers.

Distinguished from the typical species of Bhinotragus 
by its more slender form, the elytra narrowing more to- 
wards the apex, and by its slender antennae ; but agree- 
ing with them in the glossy elevations of the thorax, the 
swollen lateral rim of the elytra, and the distinctly serrate 
antennae.

Genus Agaone. 
Pascoe, Trans. Ent. Soc., 2 ser., v. 22. 
Lacordaire unites this genus to Ommata ; from which, 
it appears to me distinct in the short, slender, filiform an- 
tenna?, the short cylindrical thorax, and the much shorter
