INTRODUCTION. 



In view of the necessity in Entomology of the 

 acceptance of a universal code of terms to differen- 

 tiate or describe the parts or characteristics of 

 insects, and owing to the absence of such a work, 

 I have, through the courtesy of the authorities of 

 the British Museum {Natural History), availed myself 

 of the use of their extensive library to compile this 

 book. 



I also have to acknowledge my indebtedness to 

 Professor F. V. Theobald for reading the proof-sheets, 

 and for his valuable advice ; to Mr. Grahan for the 

 great interest he has taken in this publication ; and to 

 Miss E. H. Clemetson, Assoc. Inst, of Linguists, for 

 revising the derivations. 



I shall be happy to be notified of any omissions 

 in this, the first edition, in order to render future 

 issues more complete.
