Abstract
WE welcome the appearance of the third volume of this important work, and congratulate its author upon the completion of so laborious a task. It concludes the description of the British Aphides so far as known at present, and will unquestionably form an indispensable aid to all students of the group for a number of years to come. Many more species will no doubt yet be found in Great Britain, and the existence of Mr. Theobaki's treatise cannot fail to prove a great stimulus in bringing them to light. The importance of the study of Aphides is increasingly recognised the world over, not only on account of the injurious propensities of these insects, but also because they are now known to be important vectors in the spread of virus diseases from infected to healthy plants. To the general biologist, their reproductive phenomenon, alternation of hosts, and other features have long been of outstanding interest.
The Plant Lice or Aphididae of Great Britain.
