rear them, as I suspected they were the larvae of Al aria florid a, Guen. But 

 I am somewhat puzzled; I have not found the green caterpillar on the leaves 

 but always on the buds with its head buried, eating into the bud from the 

 outside, and I could not make out whence the animal came; but Mr. 

 Saunders seems to have found it on the leaves. On examining some of the 

 buds which had a hole in them, and apparently the worm attacks only those 

 just about to blossom, I found on the inside a worm about one-third of the 

 size of the green one; more of a grey colour and marked almost exactly the 

 same, only much more distinctly, — at least it seems so to me. I did not find 

 this worm in all. Now in what relation do these stand to each other, or are 

 they quite different ? The Alaria seems foad of sweet-scented flowers ; the 

 only one I had ever taken before this year was on the Datura Africana, the 

 perfume of which is almost overpowering. — Henry Croft, Univ. College, 

 Toronto, August 16th, 1869. [In reference to the above, which was crowded 

 out of our last issue, Mr. Saunders states that he had also observed this smaller 

 larva in seed pods of (Enoihera for the first time a few days before the date of 

 Prof. Croft's letter. It was very similar in colour to the larva of A. florida, 

 but quite distinct, being very small. He has some of them now in chrysalis 

 only quarter of an inch long. He adds that he did not usually find his speci- 

 mens of Alaria feeding on the leaves, but generally with their heads buried 

 in the flower buds, as described by Prof. Croft; he fed them, however, on 

 both leaves and buds in captivity. — Ed.] 



Collecting ground on Lake Superior. — Pie Island in Thunder Bay, 

 Lake Superior, is the best place I know of for Coleoptera. Should any 

 Entomologist go to Thunder Bay, let him by all means visit Pie Island. I 

 am sure I observed 100 species that were new to me when on it, but unfor- 

 tunately I had no means of collecting. — John Macoun, Belleville. 



Captures. — Eudamus tityrus, Sm. Abb. On July 9th, 1869, I captured 

 a fine specimen of this handsome butterfly under an Acacia tree (Robinid) 

 on one of our most crowded streets; it had evidently just emerged from the 

 pupa state, for I caught it with ease in a pill box. This is the second time 

 only that this insect has been taken in London; the former specimen, caught 

 also on an Acacia tree, is in my cabinet. 



Cossus plagiatus, "Walk. (Xyleutes of Hiibner, according to Grote). — A 

 good specimen, slightly beaten, was brought to me early in July. I think 

 this is the first time it has been taken here. 



Callimorpha interrupto-marginata, Beauv. — On July 21st a fine female 

 of this rare insect was brought in to me ; it laid a large number of eggs, 

 which, however, failed to produce larvae. This is a beautiful moth, and
