This book was written primarily to furnish information concerning the mosquitoes on the islands of Mauritius and Rodriquez, but it will undoubtedly prove to be valuable to all field workers interested in mosquitoes. The book is divided into three sections. The first of these deals with the general classification, anatomy and life history of mosquitoes. This will serve as an admirable introduction to the accounts found in the more technical treatises. The second section describes the characters and bionomics of the local mosquitoes of the two islands. Four species of anophelines and fifteen species of culicines have been found in Mauritius, but no anophelines and only three culicines have been found on the sister island of Rodriquez. Although the general usefulness of the book would have been increased had other species been described, the hopelessness of making any general selection for a small handbook is evident when it is recalled
