NOTES ON THE OCCURRENCE OF HEPIALUS THULE, 

 STRECKER, AT MONTREAL.* 



BY H. H. LYMAN, M. A., MONTREAL. 



In the part of Mr. Strecker's Lepidoptera, Indigenous and Exotic, 

 dated Feb. 22nd, 1875, * s tne description, and on the accompanying 

 plate an excellent figure, of this species from a female sent to that author 

 by the late Mr. Caulfield, and which was probably taken in the previous 

 summer. The specimen was found in Phillips Square, which is about two 

 miles from its nearest known locality, by the caretaker, from whom it 

 passed to the taxidermist of the Natural History Society, who gave it to 

 Mr. Caulfield. 



From that time I can find no further record of its capture till that 

 given in the Feb., 1884, number of the Canadian Entomologist (Vol. 

 XVI., 39), by the late Mr. Bowles, who recorded having received a speci- 

 men of it during the previous year, 1883. He also stated in the same 

 note that Mr. J. G. Jack, of Chateauguay Basin, P. Q., had also a 

 very beautiful specimen of this moth, presumably taken in that locality. 



In 1889, when looking into this matter, I wrote to Mr. Jack, at 

 Jamaica Plain, informing him that I had found it recorded in the old 

 minute book of the Montreal Branch that he had found the larva of what 

 was probably a large species of Hepialus at Chateauguay, and asking him 

 for particulars about this matter, and especially whether he had ever 

 succeeding in rearing the larva to imago, or had taken this species there, 

 and mentioning what Mr. Bowles had published in 1884. To this letter 

 Mr. Jack replied that for two or three years in succession he had found 

 a larva which he believed to be a Hepialus in the stems of Acer Spicatum, 

 and one in a stem of A. Rubrum, and another in that of A. Pennsylvani- 

 cum ; that the stems in which they were found were from one to two 

 inches in diameter ; that the borings extended from about a foot above the 

 surface of the ground down into the rootstock. and that the point of exit
