of my boys, and we have naturally made not a few observations. 

 I give those for the past seven years — it is not necessary to go 

 back farther than this. 



Visited my " particular spot " regularly in August each year, 

 and always met with hellargus in more or less abundance from 

 about the middle of that month ; but this year, owing no doubt to 

 the very exceptionally hot summer we have had, the first individual 

 of the second brood of hellargus was netted on the very early 

 date of August 8th. I need hardly say corydon is now out. 



In the Septembers of the years 1881 — 5, inclusive, while 

 sojourning at Folkestone and Dover, we never once failed to see 

 corydon in few or more numbers flying with hellargus, in one 

 instance so late as the 31st of the month. 



Last September, on the 4th, and again on the 7th, dozens of 

 corydon were still flying among the hellargus, the males mostly 

 worn, but some of the females quite fresh in ajspearance. 



I do not propose to write further on this matter, and would 

 only suggest that observation alone will clear up the point. 

 Theory, supported by no matter what argument, is of little use ; 

 and I feel sure that any one, having the time and caring to take 

 the necessary trouble, will find that, in places where both species 

 occur in profusion, corydon and hellargus are to be found flying 

 together at some period or other of their career. Mr. Tutt is 

 strongly against me, but I observe that he has " paid but little 

 attention to the butterflies during the last five or six years ! " 



A word now as to his data. He writes, " For example, this 

 year hellargus was out on June 22nd." Really ! I observe that 

 in a previous communication he says of hellargus, " I did not see 

 a specimen." This was at Cuxton, and I presume he meant to 

 imply that hellargus was not fully out there, or it may be 

 elsewhere, until the 22nd of June. Now, if Mr. Tutt aspires to 

 be an authority on the matter, I would recommend him to go 

 further afield for his information. Had he been with us on June 

 6th (instead of at Cuxton), he would have found hellargus 

 plentiful enough.* On the 2 1st of that month we noticed that it 

 was much reduced in numbers, and that three-fourths of those 

 still flying were worn. 



In conclusion, I decline any further controversy whatever 

 with Mr. Tutt on this subject, and most certainly it is not
