had quite 50 per cent, ichneumoned. This I put down to 

 the backwardness of the season in the earlier part of the 

 year, which delayed the emergence of the ichneumon ily, as 

 they were only just out when I was taking this year's pupae, 

 and I frequently came across last year's pupae with the fly 

 ready but not yet emerged. They also seemed subject to 

 attack by earwigs, spiders, and woodlice, which, after eating 

 the pupae, take up their abode in the cocoons. Some of last 

 year's pupae in my cages produced ichneumons in the second 

 week in June. My first B. mtiralis emerged on July 17th 

 and the last on August i6th, although I took thirteen fresh 

 specimens, dr3ang their wings on walls in the Isle of Wight, 

 on August 2 1 St. ■*' 



Mr. Lucas exhibited a series of nine specimens of Libellula

Dr. Chapman exhibited a few Erebias collected this season, 

 to illustrate how, in the genus, the most well-marked forms 

 tend to have black spots with white pupils in each 

 marginal wing cell, set in a bright brown or rust-coloured 

 band, which may invade a large part of the wing, and in the 

 other extreme, the dark ground colour may cover the whole 

 wing to the exclusion of all spots or rust colour. E. glacialis 

 perhaps covers in one species the widest range in this
