The former description of this species was made from a single old specimen, on which no tufts were visible (having no doubt, been removed in setting the specimen, which was, however, otherwise undenuded.) Since the publication of that description, I have bred the species, and the tufts in the fresh specimen are distinct, and the insect unquestionably belongs to this genus. The following description of the fresh specimen is more accurate than the preceding one. I have changed the specific name, giving it that of the food-plant.

In their papers on various species of British Macro-Lepidoptera, Messrs. Hellins and Buckler furnish us with much better accounts of the external appearance of caterpillars than can be gained from the meagre and superficial descriptions which used to be thought sufficient; and, as they have not confined their descriptions to the full grown animals, but have followed the creatures through all their moults, they have, in several cases, incidentally shown how great a difference there is between the larva just hatched and the full grown caterpillar; especially in the case of some of the Rhopalocera thus treated by them. Mr. Riley, of America, has, in one or instances, recorded similar facts.

In this sex, the labial palpi are short, not exceeding the front to which they are closely applied, porrect. In the male they are reflexed and thrown back over the dorsum of the thorax, which they equal in length. In colour and appearance the sexes do not differ. In repose the ♂ labial palpi are closely applied to the thorax in the living specimen, and from their pale ochrey outer colour have the effect of thoracic vittae.

Brush dark brown, apical joint pale yellowish. Head, thorax, and fore wings pale yellow, faintly tinged with pink, and minutely dusted with fuscous, ans with a fuscous streak on the base of the costa. Head and thorax slightly iridescent, wings scarcely so; posterior wings a little paler. Under surface and legs pale yellowish, sparsely dusted with fuscous. Alar ex. 5/8, inch. Names for Mr. C. V. Riley, State Entomologist of Missouri. Kentucky. Larva unknown. Also in the collection of Mr. Wm. Saunders, London, Ont.

This insect in the imago state closely resembles A psi of Europe, and has been, ans we believe still is, doubtfully regarded as identical by several eminent European entomologists. We thinks, however that a comparison of the larval forms of the two insects will help to dispel any doubts which may be entertained regarding the dissimilarity of the species. The following descriprion of the larva of occidentalis has already appeared in part, in the Annual Report of the Entomological Society of Ontario to the Commissioner of Agriculture for 1870, where it is given.

A common species of Hesperia in central Alabama, and that I do not find described by authors, is one that I call Syricthus communis. It is plentiful from early spring to autumn, and must be several brooded, but I have not found the larva.

The male is a little smaller, ans the white checkered spots are altogether larger and more numerous, than in the female. The ground colour of the wings is a brownish black, and longer bluish white hair spreads from the base of the forewings over the inferior portion of the primaries, and from the base of the hind wings downwardly without touching the abdominal margin

In the spring of 1871, my attention was attracted by the peculiar manner in which many of the leaves of the Laurel Oak (Q. imbricaria) were rolled up. The cases thus formed were compact and cylindrical, varying in length from one third to one half an inch, by an average diameter of one-fifth of an inch, and very neatly finished up. Several of them were opened, and each found to contain a single, smooth, spherical, translucent-yellow egg, about 0.04 inch in diameter. Desirous of rearing the insects, I collected quite a number of the interesting little nests, and watched, with much curiosity, for the larvae to appear-not knowing, at that time, what to expect.

when the descriptions of these species were prepared, I had forgotten that species had previously been described in Europe as G. juglandiella and H. evonymella. I have not seen these European species nor even any description of them, and possibly my species may prove to be the same. At any rate the names are so nearly the same as to necessitate a change of those, my species, and I therefore name them respectively G. juglandisnigrella and H. orbimaculella.

The geographical distribution of Smicra differs much from that of Leucospis. Unlike the latter genus, which is spread thinly and somewhat equally over the warm and temperate regions of the earth, Smicra, with very few exceptions, is limited to the New World, where there are some species in North America, many in Mexico and in the West Indies, and great abundance in the tropical parts of South America, and the genus has thus much more influence than Leucospis in regulating, by means of transfer, the increase of other insect tribes.

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

This huge genus comprehends insects of great variety of size and structure, but unfortunately it has not yet been found practicable to subdivide it. It contains, no doubt, material for several genera, and for the convenience of the student, if for no other reason, its subdivision is the desideratum in microlepidopterology. The young student who finds a micro with the palpi simple or but scarcely at all thickened with scales beneath, the fore wings comparatively narrow, and the hind wings deeply excised beneath the tip, and is told that it is a Gelechia, may well be astonished when he finds a larger insect, with the hind wings not at all excised beneath the tip, and the palpi overarching the vertex, with a large brush beneath the second joint, which may even present some appearance of longitudinal division, and is told thatit,too, is a Gelechia.

During my recent trip through Colorado and adjacent territory, as a member of the New York agricultural editorial excursion party, I made it a point to collect whenever an opportunity was offered. Through Kansas, the three-minute stops at the stations. many of which are out on the open plains, afforded me opportunity for turning over old railroad ties, &c., for beating the herbage and rank vegetation at the sides of the track, or for searching in the dry grass and weeds for Orthoptera.
