The genus to which this very interesting species belongs differs so widely from the rest of the Cynipidæ that it has been separated from the them as a sub-family, under the title Ibaliinœ. Its members can be readily recognized by the cultriform abdomen and more strongly veined wings, as well as by their greater size. The cultriform—i. e., knife-shaped—abdomen is in itself remarkable enough to attract the attention of all who may chance to see the insects.

Pyrameis Cardui— Usually common; some years quite rare.

Junonia cœnia.— Quite local; never very common. Mr. Scudder, on page 501, speaks of its “rapid, strong and enduring flight.” This would seem to indicate that the habits of this insect in the New England States differ materially from those in this locality or further south. It is rare that this butterfly is here observed over a foot from the ground, and then its flight is most erractic, and usually consists of a new fluttering strokes of the wing followed by an idel sail. This is also the manner of flight from Virginia to Florida, according to the observtions of E. M. Aaron.

Amongst insects which every year make theri presence noticeably apparent by their injuries, and thus win the distinction of being “Firstclass Pests” to the fruit-grower, not one, perhaps, is better known, nor, when not checked in its operations, more annoying than the currant worm, the larval state of the imported currant saw-fly, Nematus Ribesii, Scop. (=N. ventricosus, Klug).

The collection season of 1888 was, in this locality, somewhat peculiar. It opened up about the 10th of May with great promise—early moths appearing in considerable numbers. This was soon reversed— early moths appearing in considerable numbers. This was soon reversed—cool, dry weather setting in; and not until the second week of June did the weather become warm enought to produce a marked development of insect life.

The sub-family Noctuinœ embraces the typical Noctuidœ and we may taken the genera Agrotis or Hadena as normal forms, from which we have a mass of more or less divergent structural groups. The characters which are made the basis of generic sub-division, according to a natural system which I find most plainly indicated in the writings of Stephens and Lederer, need not delay us here, for the reason that I have exposes them in previous writings.

The small group of Homopterous insects included by Fabricius in his genus Derbe, but now separated as a sub-family from the other Fulgoridæ under the name of Derboides Spinola or Derbida, Stal have always been objects of interest to students of this order, partly on accoutn of their delicate from and peculiar strutcure, but their almos universal rarity has doubtless added much to their atractiveness.

Chionobas Macounii, Edw.

Egg.—White, subglobose, slightly flattened above and below, with about seventeen longitudinal ridges, which are connected by numerous fine transverse ridges. Length, about 1.2 m.m. Width, about 1 m. Laid July 11. Emerged July 27.
