PREFACE. 



As considerable time must necessarily elapse before the arrangement 

 of the exhibited series of insects can be completed, it has been 

 deemed advisable to issue the present provisional Guide. With 

 one or two exceptions all the figures have been especially prepared 

 for this work, and have been made from specimens in the Museum. 

 The full-page illustrations are all from photographs of actual 

 specimens exhibited in the Gallery. 



To facilitate reference all the specimens have been numbered, 

 except those under arrangement.

PREFACE TO THE SECOND EDITION. 



THE First Edition of this Guide, written by Mr. Chas. 0. Waterhouse, 

 being out of print, the author has revised it, with the help of his 

 colleagues in the Insect Section, so as to bring the Second Edition 

 as far as possible into line with the exhibited series of specimens. 

 This has involved a considerable amount of extension ; but the Guide 

 must be regarded as provisional, since alterations are still in progress 

 in the Gallery, the arrangement of which is far from complete.
