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.
