ground, and the path on the bush is marked by the presence of an 

 earthen tunnel, below which the insect works. Bark-bound and dying 

 wood is more liable to attack than healthy shoots coming from the 

 collar or from undamaged branches. The presence of a boss of wood 

 above the collar affords a place in which the termites can work un- 

 disturbed for some time. In the case of young and unhealthy branches, 

 the bark beneath the earthen covering is removed, and the termites 

 are then able to attack the sapwood. The earthen galleries may 

 ultimately completely encircle the branch and the latter will be eaten 

 away. Various species of ants have been found to nest in abandoned 

 galleries. The follo\\'ing suggestions are made for controlling this 

 termite : — (1) Young tea should be cut back to the ground in order to 

 avoid the formation of single-stem bushes. (2) Existing single-stem 

 bushes which are badly attacked should be cut back to the collar. 



(3) Damaged, bark-bound, and unproductive wood should be removed. 



(4) Efforts should be made to prevent the insects from becoming estab- 

 lished on the bushes ; this can be done to a great extent by good 

 cultivation and pruning.

The folloAving insect pests were recorded in Ceylon during 1915 : — 

 On tea : Zetizera coffeae (red borer), Heterusia cingala (red slug), 

 Lamellicorn larvae, Natada nararia and other nettle grubs, Homona 

 coffearia (tea tortrix), Helopeltis antonii (tea mosquito), Eriophyes 

 {Phytoptus) carinatus (purple mite), Orgyia postica (small tussock 

 caterpillar), Stauropus alternus and various species of Psychidae. 



On dadap (Erythrina) : Dasychira horsfieldi (large yellow tussock 

 caterpillar), Terastia meticidosalis (dadap shoot borer) and Anoplo-
