On the 7th of June, while turning over some loose rails lying on a moist piece of ground, near the edge of a wood, I found attached to the underside of one of the rails, lying high and dry, two spincus larvæ, which, from their appearance and location, I at once suspected to be the larvae of some species of Argynnis. The wild Violet also, the food plant of at least several of this family, growing in abundance here, helped to confirm my suppositions.

It is necessary for me to correct a serious error into which I have fallen.

At page 165, v. 3, I have described a larva mining the upper surface of leaves of the White Oak (Quercus alba), which seemed to me to answer the requirements of Dr. Clemens' Lithocollctis tubiferella, which also mines the leaves of Quercus alba. The larva was not removed from the mine, but viewed through the integument.

In a very interesting paper published by Professor Zeller in the Transactions of the Royal Imperial Zoological Botancial Society of Vienna, under the date of July, 1868. I find the description of a North American Gelechia. The specimens were communicated to Prof. Zeller by Baron V. Osten-Sacken. I give here a free translation of Professor Zeller's comparative description

Head and palpi very pale ochreous, almost white, a little darker on top, a dark brown spot extends almost entirely around the base of the third joint of the palpi, and another entirely around it before the apex. Antennae brownish, with about six white annulations in the apical part.Thorax and base of the wings pale ochreous, sparsely dusted with fuscous, with a fuscous line across the wing close to the base. About the basal one-fourth of the wing a fuscous streak passes obliquely backwards as far as the fold, and from thence to the apex the wing is pale ochreous, rather thickly dusted with fuscous and dark ochreous, with the extreme apex fiscous.

The wasp-like moth of the peach borer, Egeria exitiosa will be busy during the present month, depositing her eggs on the bark of the trunks of the Peach trees; then as soon as the eggs hatch, the young grubs wil1 begin to eat their way to the inner bark, where it is difficult to reach them. Much good may yet be done, either in preventing the moths from laying their eggs, or, if laid, in destroying the young larvaæ, by brushing the trunks and main branches of the trees with soft soap, reduced with lye to about the consistence of paint.

In Dr. Clemens Tineid genus Anaphora,the fore wings are 12-Veined. The submedian fold, however, seems to me to become a true vein towards the margin, giving an additional vein (vein 1b). Internal nervure, vein 1a, shortly furcate at base. Median nervure sending out vein 2 near the extremity to internal angle ; and emitting 3 and 4, nearer together, on to the external margin. From the base of the wing at the middle of the discal cell, a “veinlet” is emitted which is furcate before the centre of the wing, sending one branch, the lower, out to extremity of the ce1l between the origin of 4 and 5, near 4, and angulatedly connected with it, while 5 seems independant.
