The structure of the Termites nest usually differs according to the 

 species by which it are constructed. A series of those collected may 

 be seen at the agricultural department in Kuala Lumpor. 



The Commoneb Species of Termites met with on 

 Rubber Plantations. 



By enumerating the commoner kinds of termites found on Estates 

 some idea of the number of species which may be present and doing 

 no harm will be gained. It is this fact which it is necessary to impress 

 as I feel sure that many thousands of dollars are yearly expended in 

 destroying species which are either beneficial, or of no economic 

 importance to the planter. 



The following key taken from Haviland's paper on Termites, 

 although perhaps technical may be of use to some in discriminating 

 between the species, but as other species are harmless, for all practical 

 purposes it is only necessary to be able to recognise T. gestroi. 



Key. 



(I) Lobes of the thorax projecting over the underparts, head large 

 and broad with powerful mandibles ; legs projecting beyond the apex of 

 the abdomen. 

 Fungus growers. 



(1) General colour blackish above 



(2) General colour pale with rufous head 



(a) Size larger ; antennae with 



11 segments 



(b) Size smaller; antennae with 



15 segments 



(II) Lobes of the thorax projecting but 

 slightly over the underparts ; 

 head with a large foramen (hole) 

 secreting milky fluid ; mandibles 

 fairly long but slender, outline 

 of body oblong, head rufous, ab- 

 domen white, sometimes grey 

 from intestinal contents 



(III) Lobes of the thorax not projecting, 

 species usually of small size ; ab- 

 domen arched. 



(1) With slender mandibles ; abdomen 



sulphur yellow 



(2) Mandibles rudimentary ; with a 



conical projection on head ; gener- 

 al colour blackish brown. 

 {a) Head much swollen ... 

 (h) Head but slightly swollen 

 These names will be unfamiliar to many and it will be as well to 

 apply popular names to some species.

T. Malayauus. 

 T. pallidus.
