Ecuador (Buckley). 
An extremely pretty species, distinguished, besides its colours, by 
the very long apical spine of the elytra and the scarcely prominent 
thoracic tubercles.

Rio Janeiro, Brazil. 
This common Brazilian insect, known in collections under the 
catalogue name here adopted, has, I believe, never been described. 
Acanthodeees pupillatus.

Venezuela and New Granada. 
Also a well-known insect in collections, and not previously de- 
scribed. I have adopted the name given to it in MS. by M. Chevrolat. 
In form, and in the thoracic tubercles and prominent elytral carinae, 
it agrees with A. luctuosus, and with the genus Discopus. The ciliation 
of the apical joints of the antennae, and the dilatation of the anterior 
tibiae are possessed in minor degree by the European A. varius. 
Acanthodeees absteesus.
