1. E. castanea, sp. nov.

♂. The form of the wings is exactly like that of Senegalensis, H. S. Upperside.—The ground colour is rich chestnut-brown, marked by broad black series of spots and bands. Upon the primaries these markings are as follows:-In the cell a longtiudinal basal streak, a transverse line, a figure 8, a twice curved transverse line, and a broad bar at the end of the cell constricted in the middle; below the cell there is a short basal band curving inwardly; beyond the cell there is a wide band running from the costa toward the outer margin as far as the lower radial; and then abruptly turning and extending to the middle of the inner margin; beyond this is a broad band of diffuse spots, wide on the costa, narrower beyond the end of the cell, and gradually widening as it apporaches the inner margin; beyond this is a submarginal series of very black round spots.

C. Mus, nov. spec.

♂. Head palpi and thorax whitish gray. Antennae brown, with whitish stems. Abdomen gray, intermixed with black hair. Primaries dark gray, with veins indicated more or less by white. A broad blackish transverse band between two whitish lines, which are slightly toothed at intersections of veins. Basal space whitish, with black tings along costa. Fringes gray, with brown accentuations at termius of subcostal and median veins. Secondaries dark chestnut-brown, fading into whitish tinges along anal margin and in basal space. A faint, whitish mesian line. Fringes gray and brown alternating.

P. tolteca, nov. sp.

♂. Antennae light brown. Eyes black. Head, prothorax and thorax snowy white. Tegulae snowy white, with black hairy centre band, connecting it with the black haired abdomen, just like in T. velleda, Stoll. Abdomen metallic black, clothed with long hair and long drawn out analtuft. The latter intermixed with white hair. Primaries dark slate, especially in the interspace formed by a marginal and double central transverse line as well as along costa and internal margin. Veins white. A lunulate white discal spot, and whitish tinges around it.

In the Nov., 1892 number fo the Canadian Entomologist, pp. 269–70, there is printed a paper which was read by Professor H. Osborn before the Entomological Club of the A.A.A.S. at its Rochester meeting in August, 1892. It is entitledL “Honey-bee or House-fly”. In this article Professor Osborn questions the view, first advanced by Hyatt and Arms, that the Diptera are to be considered the highest insects.

Coleoptera may be described as Mandibulate Insects, with the forewings horny and the two basal abdominal joints invisible on the venter.

A reduction in the number of abdominal joints at the tip and in the number of joints in the tarsi indicates advancement in rank among Coleoptera. Likewise, a specialization of the antennae to clavicorn or lamellicorn indicates advancement, as well as does the degradation of the larva.

In a short paper publihsed in the Trans. Kans. Acad. Sci., Vol. XIII., on the occurrence, in a single restirced locality in Arizona, of a species of Micropeza, I gave a very brief resumé of the food-habits of some of the better known families of Acalyptrate, Muscidæ, with the view of suggesting the possible habit of the species there considered. This prompted me later to bring together all avialble notes on the subject. As these small flies are of much economic importance, both as being injurious and benefical, I have left that a quite compelte summary of their larval food-habits would be of much use to the working entomologist, besides being of no little importance to those who may be making a special study of the diptera.

Truly wonderful is the adaptability of some individuals when placed under circumstances tending to diminish the reproduction of their race. Desrious of raising larvæ of Papilio philenor, I planted two years ago five vines of Dutchman's Pipe (Aristolochia sipho) in my back yard, which in the summer of the present year (1892) covered a wall and fence 16x7 feet with luxuriant foliage.

Anisopogon ludius, n. sp. ♂.—Black, the tibiæ and tarsi dark reddish brown. Face gently convex, white pilose, bristles of lower part black; first joint of antennæ slightly longer than the second, the third joint tapering to the tip, three times as long as the second, the style slender, seven-eights as long as the third antennal joint; pile of occiput, thorax, pleura, coxæ and venter white; upper side of each front tarsal joint with a dense covering of appressed white hairs; upper side of middle femora toward its apex with a dense covering of short appressed black hairs, which, however, leave a large elliptical naked space between the apex and the middle; middle tibiae white pilose in front, and above the middle ornamented with a large patch of appressed black hairs and bristles, which form an inner and an outer fringe; inner side of hind tibiae near the tip, and also of the hind metatarsi, densely bright yellow pubescent; wings smoky brown, lightest at the apex and along the hind margin; all posterior and the anal cell open.

Some time ago Mr.Henry G. Willard, of Grinnell, Iowa, very kindly sent me of the full grown larvæ of this species. I made a few notes at the time which may be of use, owing to the fact that nothing has been publihsed in regard to the early stages of this butterfly. The food plant at the home of the insect is Rumex longifolius, but they readily ate our common species of dock found here. The full grown larva were onisciform in shape, grass greein in colour, and 20 mm in length. Most of them had a narrow, claret-coloured dorsal stripe, and the entire body, under a glass, was seen to be clothed with minute black hairs.

The young larva of Zarœa Americana appears in the beginning of July on Menyanthes trifoliata. It lies curled on the underside of the leaf. Its head is black, and its body lead-colour above and greenishwhite beneath. It develops into the most beautiful larva of any of the Tenthredinidae that I am acquanited with.

Prionia levis, n. var. or sp.

Primaries without the delicate frosted or silvery appearance, and without the numerous short, fine, strigate, brown lines of bilineata. The brown scales are present, but are uniformly and evenly distributed, save where they form the two brown lines which cross the wing, and a little darker shading near the outer edge and apex. These two transverse lines are about a third wider apart that in bilineata, the second narrowly edged externally with the clear, pale yellow ground-colour of the wing.

In describing this species in Vol. XXII., page 133, of the Canadian Entomologist, I had before me two males, one from Texas and one from Ohio. I have now before me a fine fresh female from Champaign, III., the first of this sex I have seen, and I will give here some additional characters of the species. The forewings are fawn, a little darker than in the type, but the latter was evidently a little faded. The hindwings have a few dusky scales in the outer border near the anal angle.

The genus Melanchroia has been associated in our lists with Gnophaela to form a family Pericopidœ. As a matter of fact it is a veritable geometer, with little more relation to Gnophaela than is expressed in the statement that both are Macro-Heterocera! This has, indeed, been recognized in Europe, and Mr. Butler, when identifying my specimens as M. cephise, added the remark “belongs to the geometrites”.
