254 THE ENTOMOLOGIST. 



light-fuscous mixed with darker : on costa suffused with dark-fuscous 

 to about half, with dark-fuscous dots just before and beyond two- 

 thirds ; on all segments darker opposite dark bands. Hind wing 

 cleft into six segments : first cleft from within half, second from 

 about a quarter, third from beneath base of first cleft, fourth from 

 about one-third, fifth from about one-sixth ; segments linear : light 

 fuscous irrorated with darker. Cilia light-fuscous, very long on 

 dorsal margin. 



Type c? in Oxford University Museum. It is labelled 

 ** Orcange Kiver Colony, near Bothaville, Valsch River, five 

 miles from Vaal, Blockhouse No. 74, captured April to mid- 

 June, 1902, and presented 1902 by E. N. Bennett." It also 

 bears a manuscript label, " May 1st, Blockhouse." I am 

 indebted to Professor E. B. Poulton for the opportunity of 

 examining this specimen. 



M. antennatiLs differs from M. fortis in its smaller size and 

 more dingy coloration, but is easily separated in the male sex 

 by the antennae, which are only very shortly ciliated in the type 

 (male) of fortis which I have been able to examine through the 

 kind courtesy of Lord Walsingham. 



ON THE H^MENOPTEROUS PARASITES OF COCOIDZE. 

 By Claude Morley, F.Z.S., F.E.S. 



The extremely injurious nature of the Homoptera included in 

 this family is perhaps better appreciated in warmer climates 

 than in Britain, where the amount of damage annually done to 

 our fruit-trees, &c., by these insects is by no means at present 

 fully recognized. When this is the case it will be more clearly 

 seen to what a very great extent the Hymenopterous parasites 

 which destroy them are our friends than we are at present 

 inclined to allow. Many of our leading entomologists, I have 

 no hesitation in saying, are entirely ignorant that Coccids are 

 attacked by the Parasitica at all ; and since so little is published 

 upon the subject in my friend Mr. Newstead's admirable * Mono- 

 graph of the CoccidEe of the British Isles' (Ray Soc. 1900 et 

 1902), no apology is, I think, needed for bringing forward in as 

 succinct a form as possible what is known of this fascinating 

 subject. I am greatly indebted to Mr. Newstead for assistance 

 in the Hemipterous synonymy, and to Ashmead's paper " On 

 the Genera of the Chalcid Flies belonging to the Subfamily 

 Encyrtinfe " (Proc. U. S. Nat. Museum, 1900, pp. 323-412) for 

 the elucidation of at least one of the main groups of these 

 beneficial insects. 



Extra-British hosts are denoted by an asterisk.
