Beschreibung:

The object of this volume is to describe and illus trate, in some measure, galls produced by the Cynipidae and other causes of galls on the Oak. The insects, with their parasites and other occupants of the galls, have been fully described by various writers; several pages will, however, be devoted to a few interesting and unique features of the Cynipidae. This volume is also the fulfilment of an intimation contained in the preface of my British Vegetable Galls,' explaining the reason why galls on the Oak were not described in that work. I trust the information herein contained may be the means of assisting many students to a further under standing of the subject; that collectors of these most interesting and dainty galls will be enabled to identify any specimen obtained; and, that casual observers will find in the illustrations and the text, such as will in?uence them to pursue the study in a practical manner.
