22 THE EEPORT OF THE No. 36 



verandahs and shade trees of a street in South i'arkdale, where a small swarm 

 collected. 



At the same time as the butterflies were gathering together, the Bronzed 

 Grackles were congregating. While among the insects there is of course none of 

 the friendly clamor with which the members of a flock of blackbirds greet each 

 other, yet it would seem that the butterflies are influenced by the same liking for 

 companionship as the birds. 



Concerning the starting off of a swarm of butterflies on their long journey to 

 the south, Mr. Andrews, quoted above, has made an important observation. It is 

 only by the collecting of such material that we shall ever be able to unravel the 

 mystery of the migrating tours of this typically American insect the Monarch 

 Butterfly. , 



" On Sunday afternoon, Sept. 2nd, between 4 and 5 o'clock, I witnessed the de- 

 parture of a huge swarm of Anosm plexippus. The swarm had been congregating 

 for days in Kew Gardens; they flew from the centre of the Gardens towards the 

 Lake and settled on the trees about 100 yards from the Lake. Here they stayed 

 but a few minutes, rising as it were at a given signal they flew off over the Lake 

 in a dense cloud. One thing which I particularly noticed was that their flight was 

 rapid, as if they intended reaching the U.S.A. or wherever they were going in as 

 short a time as possible. 



" I forgot to notice the direction of the wind." 



A number of Scarlet Oaks, Quercus coccinea Muench, in AVest Toronto, were 

 badly infested with a species of Bucculatrix. Several branches from these trees 

 were examined, and it was found that on nearly every leaf there were two or three 

 of the flat, silken webs, under which the larvse feed after their first moult. 



Among other lepidoptera noted as more than usually plentiful, were the House 

 Moth, Tinea pellionella, Linn., and two of the large silkworm moths, Sam in rrrropia 

 and Telea poly ph emits.

In spite of an extremely backward season and almost uniformly cool summer, 

 the record of captures is one of the best I have ever had. This is true in regard 

 both to single specimens of great rarity and interest, and to long series of insects 

 either new to me or very poorly represented in my collection. By far the most of 

 my observations have been among the Longicorns, and a great many of them have 

 been obtained by following the clues of last season. My report is, therefore, in 

 many respects a sequel to that of last year and is more nearly related to its fore- 

 runner than has usually been the case. 



In 1916 I had discovered feeding on choke-cherry foliage a single specimen 

 of a chrysomelian that was new to me. I thought at first rt was a species of Lina 

 (the change of colour on the thoracic border being mistaken for a thickened 

 margin), but it proved to be Gonioctena pallida. The capture had been made 

 about the middle of June. This season I took three specimens in the last week of 

 May, fifteen in the first week of June and a few some days later. They were all 

 found in the same corner of the collecting ground known as " The Wood of 

 Desire " ; nearly all on the foliage of choke-cherry, but two on pincherry and one 

 on balm of gilead. Careful search on similar foliage in many other places has so 

 far been without result ; I do not know how common or how widely distributed the 

 insect is. In size, shape, and colour it closely resembles Lina interniptn : the black
