EDTTOEIAL. 



Having been invited to join the Editorial Staff of the Entomo- 

 logist's Monthly Magazine, I have acceded to this request, in the hope 

 that in reference to some special branches of the work I may be able 

 occasionally to render useful service. If of late years my attention 

 has been given more especially to Exotic species, it has been from no 

 lack of interest in the constant and patient work done by those who 

 study exclusively British insects, either from a biological or from a 

 systematic point of view. AVith the help of many willing corres- 

 pondents, I hope to be able to identify correctly any doubtful species 

 of Micro- Lepidoptera that may reach me. If want of leisure and 

 occasional absence from England should prevent me from giving 

 invariably punctual attention to my new duties, the possession of the 

 Zeller collection, and my own larger accumulations, together with a 

 good special library, should give me some advantage in such work as 

 I may find time to do. It will at all times give me great pleasure to 

 render help in determining species if sent in good condition. If I 

 may thus in some small part discharge my debt of gratitude to the 

 well-loved memory of my Predecessor in the office of Editor, the 

 reward will be ample ; but I am fully conscious that no one can supply 

 the want of his kindly aid and counsel, to which so many, like myself, 

 are indebted for their first awakening and subsequently sustained 

 interest in his favourite branch of Entomological study.
