Since writing my report on the establishment and work of certain predators on coconut-feeding scale-insects in Seychelles (Bull. Ent. Res., 31, 1940, pp. 253–283) some further records of their progress have been received. These records were taken by Mr. A. Michel under the direction of the Director of Agriculture of Seychelles, to whom I am indebted for the figures. The sampling was carried out in 10 of the localities sampled previously, so that the 1940 figures represent the fourth yearly count in each of these localities. The first count in 1937 was made before the predators had been liberated, while the subsequent counts show the yearly progress in scale reduction which has been achieved since they have been active.
