Some Termites from Ceylon

Some months ago I received from Dr. Guy A. K. Marshall, Director of the Imperial Bureau of Entomology, London, a collection of termites from Ceylon which he kindly entrusted to me for the purpose of identification. The termites were collected by the Government Entomologist of Ceylon, Mr. T. C. Hutson, in different parts of the island, in tea plantations. If this is the case, the termites were presumably not collected on the plains but at some height above the sea-level, where tea preferably is cultivated. There are, however, no detailed records of the height of the localities.
