before the end of the current year." The preface to vol. vii. is 

 dated Xov, 2;Jrd, 1908, and that of vol. viii. Alarch ISth, 190'J, 

 thus leaving a period of less than five months between the dates of 

 appearance of these two volumes ! 



Sir G. F. Hampson's arrangement of the Noctuida3 differs con- 

 siderably from that of previous authors, and the genera referred to 

 the AcronyctiuuD in the present volume include, in addition- to 

 Acroin/cta and its immediate allies, many well-known British and 

 European genera usually placed in other groups. Among these wo 

 may mention Simyra, Laphijgma, Xijlomijijes, Stilhla, Petilampa, &c. 



We have no need to remark on the general character of the 

 letterpress and illustrations, as we have frequently done so before. 

 We need only say that the high standard of previous volumes 

 appears to be well maintained throughout. 



Illustrations of African Blood-suck imj Flies other than Mosquitoes 

 and Tsetse-Flies. By Erxest Edwabd Austen, Assistant in the 

 Department of Zoology, British Museum (Natural History). 

 With coloured figures by Grace Edwards. London, 1909. 

 Printed by Order of the Trustees, lioy. 8vo. Pp. xv, 221 ; 

 col. pis. xiii. Price 27s. 6d. 



The dissemination of serious diseases by flies has been known for 

 a long period, but it is only within the last few years that its 

 extent and importance has been realized. The present volume is 

 one of a series, suggested by Mr, C. 0. Waterhouse, which the 

 Trustees have undertaken to elucidate the increasingly important 

 study of blood-sucking Diptera. Of this series four volumes of a 

 Monograph of Mosquitoes, by Mr. F. V. Theobald, have been pub- 

 lished, and a fifth is promised, while Mr. Austen has published a 

 volume on tsetse-flies. The volume before us contains an account 

 of African Diptera (North Africa, except Egypt, being excluded) 

 belonging to the families Chirouomidse, Psychodidae, Simuliidae, 

 Tabauidae, Muscidye, and Hippoboscidue, illustrated by excellent 

 coloured figures of 102 species. Technical descriptions of the 

 species figured are omitted ; but general observations on the families, 

 genera, and species are given, with full particulars, as far as known, 

 on the habits, localities, &c. of the species. 



The book will be extremely useful in coordinating our present 

 knowledge of the subject, and in furnishing a solid foundation for 

 further observations ; while even from the less important standpoint 

 of systematic entomology the figures will be of great value to 

 students of the Diptera. 



In Chapter VIII. we have a list of African blood-sucking flies 

 at present known (exclusive of mosquitoes and tsetse-flies), arranged 

 under countries — another valuable feature of the work, which 

 concludes with a good and comprehensive index.
