mote the development of the larger forms of Lepidoptera, so that the lilac blooms passed without 

 the appearance of sphinges and other moths that usually attend their attractive feast. June 

 1901 was reported to be the coldest June experienced in a great many years. But on the 24tk 

 it took a turn, and a hot term followed, which lasted for five weeks without a break, with such 

 extreme heat as will have impressed itself on the memory of those who passed through it for 

 the rest of their lives. Such peculiar weather conditions had the eftect of disarranging the usual 

 appearing of common forms of insects. Some came out sooner than usual, others were late in 

 showing themselves, and others failed to put in an appearance at all, whilst a few kinds were 

 extremely abundant. 



Never before have I seen Aphides so prevalent, they were out in all their kinds and colors, 

 <m root and branch, and in such masses. But to make amends the lady bird larvfe were notice- 

 ably numerous, and no doubt this was the cause of their greatly reduced numbers at the end of 

 the season. The potato beetle was late in appearing, but was in more than usual abundance 

 later on. The imported cabbage butterfly remained scarce until the late summer broods

appeared. Papilio tnrnns (Fig. 30), the yellow swallow-tailed butterfly, appeared early and 

 stayed late. It was seen about the middle of May, and was not wholly absent in the middle of 

 August. A long continued period on the wing, which I have often seen but caiinot account for, 

 and which seems to require some explanation. Neither the Thistle butterfly, the Hunter or 

 the Red Admiral were much in evidence during the season here. The Arciymtids in their 

 various species were moderately plentiful. About the middle of August I received an intima- 

 tion from Mr. J. T>. Evans, of Trenton, that he had taken a specimen of Papilio Cresphontes 

 there in fair condition, the furthest east it has yet been reported in Canada. About the same 

 time Dr. Bethune observed one in London ; and on the 25th I picked a damaged specimen off 

 a flower with my fingers, the first of the kind I have seen abroad in several years. It was also 

 reported to me as having been taken in other places in this neighborhood. So that southern 

 butterfly has not yet succeeded in establishing itself as a permanent resident in this locality ; it 

 is even now but a periodical visitor. 



A^iosia Archippus (Fig. 31) was late in arriving, and remained scarce through the season. 

 The first one I saw was on the 12th of June, in a very worn and faded condition. Then I saw 

 another on the 15th, so bright and fresh that it might have passed for a newly emerged speci- 

 men. I received from Mr. Henry Bird, Rye, N.Y., a letter dated 15th May, 1901, in which h«
