are responsible, especially the species Calotermes domesticns, ioi the 
bulk of the damage done to buildings by white ants. A arge 
number of the species of Tenncs build small spherical nests in 
trees or shrubs at varying heights from the ground and are ot 
little or no importance from an agricultural point of view. 
The following species are the only ones which are at all common 
on rubber estates, and may, it is hoped, be recognised by the 
following key, which is based on the characters of the soldiers, 
derived in the main from Dr. Haviland’s classical paper on the 
subject.

Termes Carbonarius. 
This is one of the largest species of termites and is by no means 
uncommon both in jungle country on land overgrown with lalang, 
and on abandoned tapioca estates, where it forms nests four or 
live feet high. It occasionally attacks coconuts, but does not do
