Terms gestroi may be designated “ The Rubber Termite ” T. 
Malay anus “ The Malay Termite ” T. sulphur eus, “ The Headmound 
or Yellow Termite ” T. umbrinus , “ The Black Termite.” 
By this means a further interest may be taken in these insects as 
long technical names are seldom committed to memory. 
The following which agrees entirely with my own observation is 
an account of those species found on rubber estates given by Robinson 
in his report on T. qestroi as affecting para rubber. 
Termes Carbonarius. 
“ This is one of the largest species of termites and is by no means 
uncommon both in jungle country in land overgrown with lalang and 
on abandoned tapioca estates, where it forms nests four or five feet 
high. It occasionally attacks coconuts, but does not do any seiious 
damage, being more of a nuisance from the nips the powerful mandi- 
bles of the soldiers can inflict on the coolies plucking the nuts.” 
“ When the plantations are allowed to grow up in grass, the ter- 
mites do not seem to ascend the trees.” 
Termes Malay anus. 
“ The species constructs globular honey-combed masses of com- 
minuted vroody fibre, and cultivates a species of fungus thereon, on 
which the young are fed. There is not the slightest evidence that this 
species does any harm to living plants, and much to the contrary, arid 
it is a very moot point as to whether the money spent in eradicating 
their nests might not be better employed in other directions. Should 
however, the nests be destroyed care should be taken that the whole 
mound is thoroughly levelled and the earth will broken up and exposed 
to the sun. It is of no use capturing the King and Queen, as the 
community possesses the power of rapidly replacing them by special 
treatment of certain larval forms. 
The lenticular chambers seen on the sides of road-cuttings, etc., 
are in the majority of instances young communities or co^mes from a 
larger mound either of this or a closely allied species.” 
Termes Pall idus. 
“ A very much smaller species generally found nesting in the outer 
shell of the mounds of the preceding species. It is also a fungus 
grower and appears to be equally harmless. 
Termes Sulphureus. 
“ A small species readily recognized by its arched abdomen, which 
is coloured pale primrose yellow. The nest of old and undisturbed 
communities are roughly cylindrical tapering somewhat a the sum- 
mit. Large nests are four or five feet in height and lather less in 
diameter, and are composed of a blackish grey material,^ more loney 
combed and with far less earthy matter than that forming the nests 
of T. Malayan us, and often excessively hard. The species is commoner 
on hills than on flat land and isjnot injurious.
