In Vol. i.,No. 3, page 20, of the Canadian Entomologist, I published a description of a larva found infesting the seed of the grape, and in the Canada Farmer for October 15, 1868, page 316, a fuller description of its habits and destructive powers, and ventured the opinion that it would probably produce, when mature, a small curculio. In this I was in error, for the perfect insect proves to be Hymenopterous, a small four-winged fly belonging to Isosoma, and as it is believed to be undescribed, I propose for it the name of vitis (Isosoma vitis, n. sp.). The following notes on its history were made subsequent to the date of the issue referred to.

1. Actias Luna.—Eggs laid at night by a female in confinement, on April 30th (this is an exceptional case, they are not generally laid until June). They are lateriform, obrotundate, smooth, approaching in some cases a spheroid, opaque, very dark sepia with a faint tinge of olivaceous, though some specimens were marked with broad white bands irregularly disposed, and a very few almost entirely white.

At the request of the Head Master, the Rev. A. Sweatman, I recently accompanied my friend, Mr. W. Saunders, to the college, to adjudicate the prizes given for the collection of native insects, made by the boys during the summer vacation. Considering that this is the first effort of the school at entomology the result is most gratifying, and I feel sure that some slight notice of these collections will be of interest to the readers of the Entomologist.

Length, 1 4/10 inches; body cylindrical inclined to onisciform.

Head, flat, bilobed and horned or notched, dark brownish red with several long hairs just above the mandibles and collar.

Body, plump, smooth and firm to the touch; colour, greenish grey with small spots and blotches: on the seventh segment, two lateral black spots, on the eighth segment, a small fleshy dark coloured horn curved backwards; the anal segment terminated by two elongated prolegs; on each segment are two dorsal spots or pimples with one long hair in each; a thick fringe of greyish hair on the base of the sides; the spiracles blackish, not distinctly marked.

I wish to correct a few mistakes which I have made in the paper on this subject, which was published in the Entomologist Vol. II., No. 2.

1st. I have said that “not a single American species of Hemiteles, so far as I am aware, has as yet been described under that generic name as occurring north of the West India Islands.” This is incorrect. Mr. Riley, in his Missouri Report, has described two species, viz., H. thyridopteryx♂ ♀ , and H. Cressonii ♂, as found in his State

On the 17th of June I captured a female specimen of Hadena xylinoides, early in the evening on a sugar cask. Having confined it in a pill box I laid it aside and did not examine it again until the 20th, when it was observed that a number of eggs had been deposited. These, although examined casually by the microscope, I neglected taking a minute description of. They were about medium size, of a flattened conical form, greenish in colour, and ornamented with many striæ. The eggs hatched on the 24th of June, when the following description of the young larva as seen under a common eye-glass was taken
