18 THE CANADIAN ENTOMOLOGIST. 



unlikely. Did it get here by shortened stages and lengthened time 

 through several generations? That starts the quesiion of food plant, 

 what it is, and can it be obtained between there and here ? Latitude 

 might thus arrest its progress, at least its permanent progression that 

 way. I have often wondered why insects, which I have every reason to 

 believe were in a locality, could not be got ; and am impressed with the 

 idea that there must be many in a locality wliere one is got, and that 

 some may be in localities where none have yet been seen ; and when one is 

 taken in such localities we are apt to conclude that it is the only one that 

 ever was there. 



It was in the autumn of i88r that I took my first specimen of 

 Heliothis armiger at Hamilton. An. Rep. Ent. Soc. of Ont., 1881, p. 30. 

 And Dr. Saunders, then of London, now of Ottawa, assured me that up 

 to that time he had not taken it. It was considered then to be but a 

 transient visitor; now it could be taken here in numbers every season, 

 although reported as injuring corn for the first time last season — a good 

 illustration of how a migrant establishes itself in a new locality where its 

 favorite food plant is easily obtainable. And others may be doing the 

 same, of whose presence we have as yet had no indication. 



The other species new to the Society's collection of that sending 

 were : 



Bryophila teratophora, H. S. 



Manestra anguina, Grote. 



Schinia trifascia. Hub. 



Galgula subpartita, Guen. 



J. Alston Moffat, London, Ont 



As a postscript to the above, I will now notice another of Mr. 

 Bice's rare finds. Amongst the Hydrcecia sent to me by Mr. H. Bird. 

 Rye, N. Y., was a handsome specimen of H. Necopina, Grote, which Mr. 

 Bird said was considered by many to be a mythical species until he dis- 

 covered its food plant, and secured it in sufficient numbers to distribute 

 freely. Mr. Bice called and saw the specimens ; looked at them long 

 and intently ; pondered much, but said little. He went home and turned 

 over his more recent captures, called a few days later with a box in his 

 hand, which I took and opened ; and there, to my surprise and delight, 

 was a Necopina ; lacking the lustre of the other, but quite unmistakable^ 

 Mr. Bird's specimen recalled something he remembered taking, but said 

 nothing about it until he should see, for fear he might be mistaken.
