Tbe Australian species of Toxicum previously described having 
antennse with three joints to tbe club and not differing much in 
size from the present species, are distinctum,^lduc\., jmrvicorne, 
Mad. Tbe former of these differs inter alia in tbe extremely 
strong puncturation of tbe elytra, and tbe parallel sides of tbe 
protborax; tbe latter by tbe latter of tbe characters just men- 
tioned and by the curve of the posterior horns being close to tbe 
apex. 
In tbe present species the posterior horns are evenly bent 
inward from considerably below the middle, and are not far 
from meeting at the apex ; the protborax is more than a third 
again as wide as its length down tbe middle, and is at its widest 
immediately behind the front, whence it is very decidedly narrowed 
to the base.
