the latter are at least as long as the body. The 
upper lip is very large, and occupies the anterior 
portion of the head. This tribe is of great extent, 
but a very small proportion of the species occur in 
Britain, their characteristic localities being in warm 
countries. They are much esteemed by collectors 
for their handsome proportions, and the beautiful 
combination of colours with which many are adorn- 
ed. Some are remarkable for emitting a strong 
odour of roses, especially that named moschatus , 
which occurs in considerable abundance on willow- 
trees in the vicinity of London. In C. phyllopus , 
a native of Brazil, this scent is so strong that it is 
felt in walking through the woods to a great dis- 
tance. They are usually found in woods and on 
the trunks of trees, being very rarely seen on flow- 
ers, and they appear to derive their chief nourish- 
ment from the sap that exudes from the stems. 
The species figured as an example of this tribe is 
named 
LOPHONOCERUS BARBICORNIS.
