Here I am again imprisoned within the walls of the town, after enjoying all the liberty of the field. How unphilosophical and dissatisfying to a devotee at the shrine of Nature are the labors that attach to a locality like this! One must turn over a new leaf occasionally. To balance the ledger, even though it have golden results, is comparably but as the dust of the balance. The City is stupid, hot, and odoriferous—empty, and yet full. Wealth, with its polished exterior, has long since departed, and “poverty, a wrinkle of itself,” remains. The intensity of the heat brings the hidden life without, and the town is seemingly the more full. What a wretched place in midsummer is a great City!

Catocala Sara, n. sp.

Expanse 3.10 inches. A form in size and general appearance resembling C. Aspasia, Streck., but having much darker colored fore wings, besides other points of difference. Primaries blackish gray from the base to the t. a. line, along the posterior margin to the subterminal line, and from this in a broad band to the costa, the inner part of this band running along the inner side of the reniform. This color is formed of a black or brownish black ground, sprinkled with white scales. This leaves a pale space between the stigmata from the median vein to the costa, and the whole end of the wing beyond the dark space spoken of. T. a. line indistinct, of the ground color, but with less white scales; t. p. line distinct anteriorly, one large and one small tooth opposite the reniform. Subterminal space scarcely tinged with brown, the subterminal line white with a sprinkling of black scales. Orbicular indistinct, black with a few white scales, reniform with a few white scales and an annulus of gray, Terminal space gray. Secondaries rosy red, the median band very much as in the form Walshii, not reaching the inner margin, a little constricted opposite the disc, beyond this a little enlarged, after which it narrows to less than half tlie costal width. Terminal line like Walshii, with an internal excavation before the anal angle that reaches half through the band.

In order to make the following list as complete as possible, I have included the species in the cabinets of Messrs. H. H. Lyman and F. B. Caulfield, of Montreal, with those in my own collection, taken at Quebec, and also those credited to Mr. Belanger, of Quebec, in Packard's “Monograph.” When a species is found both at Quebec and Montreal, no locality is given; when found only at either place, Quebec is indicated by a “Q,” Montreal by an “M.” The list comprises 115 species and 3 varieties. The names and arrangement are those of Packard's “Monograph.”

The foliage of the trees in this city is undergoing spoliation by the larvæ of this moth. Many of the trees are entirely denuded of their leaves, particularly the Silver-leaf Poplar, the Ailanthus alone escaping attack. The writer suggested to the authorities last spring that handpicking of such cocoons as contained the deposit of ova was the only sure way of exterminating these insects. Had such service been rendered the trees at that time, this damaging visitation would have been prevented. There is good reason to believe, however, that what the authorities have failed to do, a young army of parasites, “Pimpla,” which have put in an appearance during the last fortnight, are now actively attempting, and we shall probably be rid of this moth another year. The ova commenced to hatch out about the 25th of May, and the larvæ began to assume the pupa form about the 21st of June; ten days thereafter the imago was discovered depositing ova. Out of twelve cocoons gathered on the 15th of July, four yielded the parasite already referred to. I would note here in connection with this parasite a circumstance very commonly observed among the Lepidoptera. I discovered two ♂ parasites upon a cocoon containing the pupa of this moth. I drove them away several times, but they as frequently returned.
