I herewith send you some memoranda of what I have done during the past summer, largely owing to the assistance of Mr. Mead. I consider it my most successful season in the way of obtaining larvæ eggs. One of the most interesting species we discovercd was Lycaena pseudargiolus. Mr. Mead noticed a female hovering about flowers of Actinomeris squarrosa, which is a weed found hereabouts in company with A. heliianthoides–the last being a thousand-fold most numerous-andl suspeceing that she was oviposing, he made a careful examination of the plant.

♀. Larger thanBaltimoralis and differing at once by the parallel continuation of the transverse lines to the internal margin. The peculiar conformation of the dark median space, described by Guenée as resembling “une espéce de colé in Baltimoralis, is therefore wanting in scutellaris. Differing from crassalis, than which it is larger, by the inner transverse line being incepted on costa and joining internal margin without fusion with the outer transverse line. In coloration scutellaris is unusuallv bright and contrasted.

Since the preceeding accounts of the genera Evippe, Eidothea and Helice were sent to the publishers, I have taken a single speciment of the species described below. Its small size, general appearance and the tufts of raised scales at first inclined me to place it near Laruna; but a, closer examination shows it to belong to the Gelechidæ, and to the same group (or subsection of Gelechia) witin Evippe, &c. and Gelechia difficilisella.

It seems probable to me that Limenitis proserpina will be found related to L. arthemis, the two being forms of one species, as in Grapta comma and dryas, and I desire to call the attention of Lepidopterists who live where these species or forms are found, that they may observe them from this point of view. They are alike in size and shape, and so far as my experience and that of Mr. Mead goes (confined in both cases to the Catskill Mountains), they are always associated.

I have received, through the kindness of Mr. C. V. Riley, a specimen of this fine species which has been heretofore unknown to me. It is, perhaps, a little larger than unijuga and very different in character (also, therefore, distinct from junctura, from my recollection of that species in the British Museum) ; it resmbles the European elocata in the appearance of the forewings : these are evenly intensely powdered with dark scales on a grey ground color which becomes yellowish brown over the median spots and subterminal space.
