H. Lineola. Ditto. — A. Lamek ; Wartsbeck, near Hamburgh^ June, 1846.
[This list is one of great interest to the English Lepidopterist : the latitude of Hamburgh is the same as that of the middle counties of England, and the face of the country diversified like ours, with woods, meadows, and cornfields ; yet, without any ob- vious cause, the number of species is at least a fourth larger than ours, and some which with us are of excessive rarity, are there extremely common: but if we make the comparison still more rigid, limiting our attention to any spot, as our correspondent has done to the vicinity of Hamburgh, we shall find scarcely forty species or less than half the number our correspondent has enumerated. — Edward Newman].
Do Insects feel or do they not?—The question "Do insects feel or do they not?" having been recently discussed in the ' Zoologist,' I think it is not too late to offer a few observations on the subject, being, as it is, to entomologists, one of real and prac- tical importance. On it depends entirely the use of seeking means for killing insects when captured as quickly as possible, or the utter uselessness of such research. And on it hang many of the arguments to which entomologists are so often exposed when de-
