The following notes are based almost entirely upon actual rearing records, the hosts in most cases being insects of economic importance. The greatest attention has been paid to parasites of the small moth-borers of sugar-cane (Diatraea spp.). The systematic work has been done entirely at the British Museum and would have been impossible without the facilities in literature and collections there, and the great help of Mr. D. S. Wilkinson and Dr. C. Ferrière, of the Imperial Institute of Entomology. Types of new species are in the British Museum.

The purpose of this paper is to establish as clearly as possible the status of the genus Aneristus Howard, to assemble all the available information concerning the habits and host-relationships of its members, and to make known three new species from the West Indies. So far as known all the species of Aneristus are primary parasites of the non-diaspine Coccidae or soft scale insects and are of great economic importance.

During the past fifteen years the attention of Economic Entomologists in Central America and the West Indies has been increasingly directed to the damage done by species of the genus Brassolis to the foliage of coconut and other palms. In some of the scattered papers (q.v. Review of Applied Entomology, Series A, 1913–22) dealing with these ravages one finds references to the natural control exercised by Hymenopterous parasites. So far as I am aware the only writers to mention by name any of these enemies are C.Schrottky (1909) and G. E. Bodkin (1917), who list four species between them. Since the spring of 1920 I have examined two small collections of Hymenopterous parasites of Brassolis from Trinidad and British Guiana respectively. In each of these the same one of Schrottky's species is represented, and in all I am now able to list seven species. Two of these have not been seen by me, and two more (Brachymeria and Spilochalcis) are probably recognisable from extant descriptions. In the case of the Telenomus it is hoped that the figures given may facilitate recongnition. Though Ashmead's description of this species is very incomplete, I have forborne for the present to supplement it, since the diagnosis of these minute parasites for any particular geographical area can be attempted best in a comparative key. only the Anastatus has been fully described.

The material here described was mostly obtained as a result of a period of study and travel in East Africa in 1939. Two of the species were reared from Coccidae of the genus Aspidoproctus at Amani, Tanganyika Territory, and their life, history is the subject of an accompanying paper. I am greatly indebted to Dr F. W. Edwards, F.R.S., for allowing me to describe the remarkable species collected by him on Ruwenzori, Uganda, in 1935. I am also most grateful to Dr R. H. Le Pelley of the Scott Agricultural Laboratories, Nairobi, and Dr E. A. Lewis of the Veterinary Research Laboratory, Kabete, Nairobi, for other valuable new material. In addition, The Imperial Institute of Entomology has kindly allowed me to examine and describe material from Uganda in their possession which had been erroneously identified as Cryptochaetum iceryae (Will.). Type specimens of all species will be deposited in the British Museum.
