I have received from Canada (London, Mr. Saunders) a nerv and easily recognizable species of Nola,larger than ovilla, and in describing it, I have again gone over the characters of Argyrophyes, which I find to be allied to Nola, and not to belong to the Geometridæ. I have corrected my former observations on Argyrophyes, which I find to have been largely erroneous.

Nola sexmaculata, n. s.

General color light brown. Upper part of pronotum and hind femora with a reddish tinge. Face sometimes mottled. Antennæ light brown infuscated apically. The usual black band behind the eye broad and distinct, and reaching last division of pronotum, bounded below by a narrower white stripe. A broad white stripe from base of elytra connects with a white stripe at insertion of posterior femora, forming a right angle. Outside of hind femora is crossed by two indistinct dusky bands that extend upon upper edge. Lorver sulcation reddish. Knees black. Hind tibiæ blue. Elytra light brown with very small black spots in the disk.

The life history of Meloe, as given by the Editor in the December No. of this journa1, agreeing very closely with that of M. angusticollis Say, as far as my knowledge of its habits will permit me to judge, it occurred to me on reading Mr. Brodie's very interesting notes in the January No., that unless we have in this country a double brooded Meloe, some one must be referring another species to Say's angusticollis.

Last fall I obtained a few eggs from a female L. proserpina, in Sept., while in the Catskills, and raised eight larvæ to hybernation, which took place after third moult. This spring I have carried four of these to maturity with the following results : 'fhe first chrysalis gave butterfly this morning (April 29th), a male arthemis. For some hours before the emergence the white band of arthemis was distinctly seen through the wing case. The second was but a few hours younger and during this afternoon has given proserpine male. I expected this, as here there was no white band on the wing case.

The suggestion of Mr. Hill (quoted on p. 89) that Homopteras “edusa and lunata are possibly sexes of one species,” has reminded me of my own doubts regarding not only edusa and lunata, but also Saundersii, and caused me to make a careful examination of my material.

My entire stock numbers 83 local specimens, arranged after authentic types in three series, consisting of 42 “lunata,” 24 “Saundersii,” and 17 “edusa.”.

The specimens separated as lunata show no white lines or areas on upper side of wings.
