Here he worked, unpaid, in the Insect Room of the Natural History Museum, organising and cataloguing the world collection of aculeate Hymenoptera.

To Col. E. R. Johnson, late of the Indian Medical Service, I owe the gift of a small but very valuable collection from Simla and from Shillong in Assam.

To Col. Swinhoe I am indebted, not only for the gift of many specimens, but for the privilege of examining at leisure the fine series of Indo-Malayan forms contained in his collection.

Mr. Gilbert Rogers, of the Imperial Forest Service of India, in the most lavish way, employed native collectors in the Andaman and Nicobar Islands, and has generously placed the material collected at my disposal.

Messrs. Allan and Craddock, of the Burma Forest Department, have sent me small but very useful collections from Pegu and the Southern Shan States; and to Mr. E. E. Green and to the Hon.

These were particularly valuable to me for comparison with the northern Indian forms.He also extensively improved on the earlier published information from Frederic Moore and Lionel de Nicéville.

De Niceville's enthusiasm communicated itself to others, and his ever ready and generous help encouraged many who, like myself, feel that his early death has been almost an irreparable loss to Indian Entomology.
