Prof. Caesar: In regard to the matter of side-worms, I may say that every 

 persons who endeavors to spray thoroughly for Codling Moth finds that far the 

 greatest trouble is to prevent the worms from entering the side of the apple, 

 especially if there are two broods and if it is the first season the orchard has 

 been sprayed.. I do not know anything about the influence of temperature on 

 this questions of side-worms, but I do know that in Ontario side-worm injury 

 is abundant hoth on high land and on low land. 



Mr. Gibson: Mr. Chairman, I should like to remark that in Dr. Cosens' 

 report which he sent as Director, he makes a brief mention of the occurrence 

 of the Lesser Budmoth on pear trees in Toronto, and he also mentions that it was 

 quite abundant on an apple tree. This insect is treated of in a bulletin published 

 by the U. S. Bureau of Entomology. 



The President: If there is no further discussion on this paper we will 

 proceed to the next by Mr. Winn. 



THE HOME OF GORTYNA STRAMENTOSA 

 Albert F. Winn, Westmount, Que. 



This moth is one to which but little space has been devoted in our literature, 

 but being a typically Canadian insect, perhaps you will pardon a longer and more 

 rambling paper than intended for the meeting. 



In Vol. XXXII, pp. 61-63 of the Canadian Entomologist, Mr. J. A. Moffat, 

 late curator of our Society, published a copy of Guenee's description of the moth, 

 an enlarged half-tone cut of it and some remarks on its occurrence. This was 

 followed in the same volume by a note on p. 119 by Mr. Grote, and a reply on p. 

 133 by Mr. Moffat. The species has again been figured by Sir George Ilampson in 

 Vol. ix of the Phahvnida^ of the British Museum, plate 138, to which we will 

 refer elsewhere. From Mr. Moffat's article we quote the following: " Stramentosa 

 has been taken regularly at Montreal for years past by collectors connected with 

 the Branch of the Entomological Society of Ontario there, apparently none know- 

 ing of its existence there except themselves. Mr. Brainerd int-ends to make a 

 vigorous effort to discover its foodplant next season. '• 



Although over fifteen years have elapsed since this was written and we had 

 already been hunting over ten years, the search for its foodplant and consequent 

 laying bare of the life history has been carried on faithfully and well by various 

 members of our Branch, and at last it has fallen to my lot to have the pleasure of 

 entirely solving the mystery of its hiding-place. It is not necessary to particularize 

 the members who have tried to locate it and failed; practically all of us interested 

 in Lepidoptera have searched our Mountain for infested plants possibly tenanted 

 by stramentosa, and we had a few years ago the aid of Mr. Henry Bird for a couple 

 of days; but although we were actually within a few feet of scores of larvt?, they 

 were not detected. It is doubtful if any other Canadian insect has had so much 

 time and thought expended on its habits and life history, and as successive seasons 

 closed with the flight of the moths around our street lamps in the fall, and oc- 

 casional captives on flower heads, we began to feel certain that no visible clue could 

 be hoped for in the plant and that nothing but sheer luck would ever disclose the 

 secret, but we kept on pulling up and splitting down all sorts of possible and some 

 impossible plants. *
