NOTES ON THE SEASON. 

 By Richard South. 



On every hand I hear complaints of the season from lepi- 

 dopterists and others. The tale told by Mr. Prest, of York 

 (Entom. XV. 162), is echoed by an entomologist working from the 

 Kentish coast, and is quite in accord with my own experience in 

 North Devon (Entom. xv. 153), and lately in Norfolk and Suffolk. 



I hope we shall have notes from all parts of the country, and
