I hardly need an apology for presenting from time to time to the entomological public descriptions of galls of Cecidmyiæ, even when I did not succeed in rearing the fly. Such observations, unless published soon, are very apt to be lost; once published, they gradually accumulate and furnish a welcome material for the future monographer. To facilitate reference, I give here a list of my previous publications on the galls of North American Cecidomyiæ

Having been requested by the worthy Editor of this journal to contribute a few hints on sugaring for Noctuæ, I have endeavored to put together a few notes may prove servicable to those who may not have been sucessful in this method of capture. To begin with, it ought to be a golden rule never to abandon a locality, even should it yield nothing for a few nights. Often have I sugared a new locality night after night, with absolutely no results, but by presevering the moths have become attracted to the place, and, in course of time, were swarming on every tree.

♂ . A small frail form with ciliate antennae no ocelli, and long, dependent palpi, their second joint thickly squamous. Fore wings grayish white, with their inner line black, fine, angulated. Outer line denticulate, followed by a pure white shade. A pure white shade in the place of the subterminal. Hind wings dusty white. Beneath the fore wings are pale fuscous, immaculate; hind wings whitish with a discal dot. Expanse 16 m.m. Canada, Mr. Saunders. This species differs decidely from the N. Am. species described by prof. Zeller; I do not find descriptions of N. Am. species in any other author.

In September, 1873, Mr. T. L. Mead, who was then at Coalburgh, observed a ♀ pseudargiolus depositing eggs upon the flowers of Actinomeris squarrosa, and on examining the flower heads found a number of eggs. He brought home two of the females, and enclosed them in a muslin bag upon the flower heads of the same plant, near my house, the plant being not at all an uncommon one here. Several eggs were soon deposited, and in due time the larvae were hatched and some of them were carried through to chrysalids, a change which occurred about the middle of October.

If any of the insect host is a proof of high art in nature, and of the beauty of the creator's thoughts, it is most assuredly the fair creature whose name is mentioned above. Allied to families whose members are among the greatest of the insect world, and having cousins and connections surpassing in size and beauty all others of their kingdom in this Dominion, still this moth is as pre-eminent above its fellows as is its namesake–the fair empress of the sky–above the lesser lights that rule the night.

During the past month (July) I have endeavored to obtain the eggs and the larva of some of the butterflies common near.this place (Hunter), in the catskill Mountains, and have met with considerable success.

The most interesting discovery was that of the food plant Phyciodes tharos, which had baffled my endeavors for the past four or five years during which time Mr. Edwards and myself have tried a great number of plants without avail.

The smallest N. Am. red-winged species known. It has a resemblance to polygama and fratercula in the ornamentation of the primaries. Fore wings gray, shaded with blackish; lines black. A diffuse basal black shade. T. a. line diffusely shaded with black. Reniform small, yellowish, more or less distinctly double ringed. Sub-reniform small, yellowish, disconnected with the t. p. line. T. p. line shaped much as in Polygama. Hind wings bright red.

♂. Eyes naked, all the tibiae spinose antennae brush-like. Thorax, head and appendages brownish red. Anterior wings brownish red, silky, Median lines faint, blackish, tolerably approximate. T. a. line nearly straight, t. p. line eyenly rounded, tending to be obsolete on the veins; costal dots mark the inception of the lines. Median shade very faint, Stigmata ohsolete; there is merely an indication of the reniform. Subterminal line pale, narrow,continuous; terminal space darker than the wing, the fringe ligher.

Allied to precationis and ,gamma. It differs by the distinct yellow shaded geminate t. p. line having but a single acute tooth at vein 2 ; the line running more outwardly at this point, and being othewise even throughout. Also by the shape of the metallic spot ; this is open, silver bordered, running outwardly obliquely from the median vein to the t. p. line at vein 2, sub-triangulate, the bordering lines fusing outwardly to a point, forming an oblique uneven V. The median space below and beyond the metallic mark is shaded longitudinally with obscure chalceous.

I define this new genus with great hesitation and doubt as to the propriety of so doing. The only reason for separating the species described below, and which I place in this genus, from Evippe (vid. E. prunifoliella, ante v. 5, p.185) is found in the neuration. The other characters are those of Evippe, and, as stated below, it is very near to E. prunifoliella in ornamentation. The neuration of the forewings is exactly that of Eidothea vagatioella (loc. cit. sup.p. 187), which it also resembles in ornamentation, but less closely than it does Evippe prunifoliella.

Expanse, 2.70 inches. Primaries scalloped, apparently brown being densely sprinkled with black scales on a reddish gray ground. Reniform tinged with red, clouded anteriorly with black, and having a black central spot. Sub-reniform indistinct. Terminal line nearly obsolete, the grayish band which precedes it showing plainest on the costa. All the transverse lines are black, and a curved row of seven black dots appears on the interspaces along the outer margin. Fringe dark, tipped with white.
