told that it is the unexpected that happens, and, as far as last 

 dragonfly season was concerned, it was perfectly true, for, 

 while spending a few days in the New Forest, at Whitsuntide, 

 Mr. Carr and myself found the same species in a very 

 restricted spot there, and between us secured, after lengthy 

 search, eleven specimens, two only being females, and those 

 both of the variety aurantiaca. They were just coming on 

 the wing at the time, and possibly ma}- have been more 

 common later, but they were apparently over by the end of 

 July. Nor even was this all, for, stranger still, Mr. Blenkarn 

 met with the species again, securing at Abbot's Wood two 

 specimens, which he brought up and exhibited at one of our 

 meetings. 



For the third year in succession Syuipetrnm fiaveoliini was 

 with us, and we seem forced to conclude that in each case 

 their presence here was due to a migration, for during the 

 three seasons but one female was noticed, and that, taken 

 on the coast of Essex, was clearly an immigrant. 



Another striking feature of the past season was the 

 plentifulness of a generally extremely scarce dragonfly, 

 j^sclina mixta. Quite a large number of the members of our 

 Society have taken the species, and brought up specimens 

 for exhibition, though, owing to the wariness of the insect, 

 few captures were made compared with the numbers seen. 

 There may have been an immigration in this case, though I 

 am inclined to think not. In two localities where I have 

 met with it for several years, there seems to have been a 

 gradual increase in numbers during the last two or three 

 seasons. Have the hot summers had anything to do with 

 this? 



One more matter I must refer to in this connection is a 

 migration of Libellala quadriinaculata . This migration was 

 observed in Belgium in June, and recorded somewhat fully 

 in a Belgian magazine, and in the " Entomologist's Monthl}^ 

 Magazine " Mr. McLachlan has given an abstract of it. It 

 seems that in Belgium they were inclined to think that the 

 migration came/ro7« England. This was not the case ; but 

 it is clear from the observation of Messrs. H. Stocks at 

 Margate, G. Bolam at Berwick, G. T. Porritt at Hudders- 

 field, and A. J. Mann between Margate and Broadstairs, 

 that part of it readied England during the same month. 

 It seems, too, that a migration of Lencorrhinia duhia, a more 

 northern species, arrived at Scarborough about the same 

 time. 



Some attention has been paid to the earlier stages of
