The little insect which I have made the type of this new genus, unites in itself the characters of several genera.

Tongue naked, about as long as the maxillary palpi, which nearly conceal it. The maxillary palpi are about as long as the labial palpi and in the dead insect are laid upon the coxae ; they are rather densely scaled, the scales being somewhat roughened.

This species was bred from minute mines in the leaves of Persimmon trees (Diospyros virginiana),gathered in great abundance at the “Bee Spring” camp of the Kentucky Geological Survey, in Edmondson County, a few miles west of the Mammoth Cave. I have never met with it in Northern Kentucky, where the Persimmon tree also grows, but is comparatively rare.

Mr. J. E. Fletcher has a note in the March No. of Newman's Entomologist, on “Controlling Sex in Lepicloptera” He says :“ During last summer, I had a few larvæ of EXapate congelatella feeding on privet; as I was greatly occupied with other things, they were neglected ; the supply of food was very irregularly given and short in quantity, yet the moths produced from them consisted of four males, full sized, and eleven females, some of these latter being much below the average of the species in size.”

Both of these species occur abundantly in this locality; but the latter (my specimens can be nothing else) has the apical vein furcate before the apex, whilst Dr. Clemens says that it is simple. Mr. Stainton says it may be B. basilaris, Zeller.

A collection of Tineina received from Mr. Belfrage, of Waco, Texas, presents some points worthy of mention apart from the descriptions of the new species.

The collection consists of about two hundred and fifty specimens in tolerably good condition, referable to seventy-six species and twenty-seven genera. Such a number of genera and species is evidently typical of the Tineina of thelocality where they were collected.

Slate color, tinged with ochreous; apex of the abdomen yellowish ; two longitudinal dusky lines on top of the abdomen, which, however, are invisible in the dead specimen. Al. ex.,6/16 inch. Kentucky.

The case is ochreous, slender, cylindrical, tapering a little to each end, and compressed or pinched at the posterior end, so as to divide it into three small ridges. It is about half an inch long, and was found adhering to the bark of sugar trees (Acer saccharinum.)

In the preceding paper on this genus I mentioned that I had found the larva of this species mining the leaves of Ampelopsis QuinQuefolia. Since that paper was placed in the hands of the Editor, many months ago, I have succeeded in rearing it from the mine.

Among the material submitted to me for determination by Professor Packard, from the Peabody Academy of Science, are specimens from Maine and Massachusetts of two species of Agrotis allied to, but distinct from A. triangulum. Agrotis attentus. N. sp.

The eyes are naked. The middle and hind tibiae are armed, but the fore tibiae are without spines; male antennae siurple, bristled and pubescent.

In collecting Catocalas at Ohio, Ill., I have found them, during July, invariably abundant upon Black Locust (Robinia Pseudacacia), which, at that time, exudes considerable sap from the holes made by borers. Last season I pinned rags, dipped in molasses, to three or four of these trees, and from the middle to the last of July obtained from them over thirty Catocalas of ten species.

Since so much has been written upon the habits of our ordinary Leaf-cutting Bee, it would seem presumptuous for me to offer anything further in connection there with. But a few facts which came to my notice recently are sufficiently interesting and important to merit publication.

During the latter part of June, 1873, several cells, a half dozen in number, were sent to me by a friend, who had accidentally brought them to light while digging underneath the shade of a Spiræ corymbosa.

This genus, though closely allied to Stilbosis, Walshia, Elathista, &c., differs from them somewhat as to the palpi, and yet more as to the neuration of the wings. In the neuration it is near Stilbosis, but in many respects is nearer Walshia.

Eyes hairy ; collar and thorax reddish brown ; the thorax of my only specimen was injured in capture, so that the presence, or if present, the size of the tufts could not be ascertained. But apparently it was tufted, as there are traces of a meta-thoracic elevation. Abdomen yellowish, with a strong basal tuft; the labial and anal tufts tinged with carneous ; beneath red; anterior wings deep uniform red; lines obsolete; nervules distinctly black; a white dot on the costa at the base ; the interior line is only represented by a white dot on the costa and on the subcostal, median and submedian nervures.

The two-winged flies are more important in nature than any other order of insects because of their number and diffusion, and the families may be briefly traced in succession previous to a more extended notice of each of them, in case the subject should become rnore interesting.

In the following arrangement the first manifestation of Dipterous. existence is associated with the inmost recesses of man's habitation. and a few beasts and birds aiso partake of its presence in their dwellings.

Primaries lanceolate ; the costa enters the margin about the middle discal cell narrow and closed by a nearly straight discal nervure. The subcostal sends off a long curved branch from about its middle, and which attains the margin behind the end of the cell. From the end of the cell the subcostal bends somewhat obliquely upwards to the costal margin. The median is furcate from the end of the cell, both branches being short and bending somewhat suddenly downwards to the dorsal margin, the inner branch being straight and continuous with the discal vein.
