As the readers of the Canadian Entomologistare aware Dr. H. A. Hagen has argued at length to the effect that the Hessian Fly was, first not imported by the Hessian troops; secondly, that it was not imported from Europe at all, and that it is an indegenous North American insect. In the Third Report of the U.S. Entomological Commission, Dr. Packard has an extended article upon the Hessian Fly, and while he alone is responsible for the general position there taken on this subject, we discussed the matter together, and the views there presented are substantially those which I held at the time, as it was Dr. Packard's desire to arrive at an impartial judgement.

About the middle of last November Miss Annie M. Wittfeld, whose untimely death I have spoken of elsewhere, wrote me that she had taken a butterfly of a species which she had never seen before, while it was laying eggs on purslane. She confined the buttefly with the plant and obtained 74 eggs. She confined the butterfly with the plant and obtained 74 eggs. It was like a Danais, she said, but the caterpillars were like a Vanessan.

Agrotis agilis, n. s.

Two males in good condition received from Mr. James Fletcher, from Vancouver, belong to a decidely different species from my semiclarata, Essay, Plate 1, Fig 9, though allied,as also to Californian gravis, and our Eastern venerabilis. Antennæ brush-like. Gray, with a brown tinge. Lines obliterate.

Eggs laid June 17th, scattered, hatched July 1st.

Egg.—Creamy white: one-twenty-fourth of an inch in diameter; shaped like a nutmeg-melon; marked longitudinally with zig-zag ridges; attached by short foot-stalk.

Newly Hatched Larva.—One-eighth of an inch long. Head large in proportion to body, honey-yellow, granulated. Body attenuated and ending in two pointed prolongations; pale amber, set with brown tubercles bearing light spines. Dorsal an side lines darker amber. Spiracles dark brwon. Head and fore legs bearing a few bristles. The insect feeds with its head downwards on the edge of the leaf. Its food plant is the sedge, Carex oligosperma.

I am not aware that any parasites have ever been reported as attacking the larvæ of Danais archippus of the maggots of Anthomyia raphani. However that may be, it will be interest to the readers of the Entomologist to know that last fall I obtained from a single chrysalis of D. archippus over fifty speciments of a new species of Pteromalus. The parasites came forth September 13, the chrysalis having been brought into the laboratory a few days before, and inclosed with a bell-jar. Specimens were sent to Mr. L.O. Howard, who has since described the species and given it the name of Pteromalus archippi.

Datana integerrima, Gr. & Rob.

Before Last Moult.—Head and cervical shield shining jet black. Body deep reddish brown, with three very fine, narrow, sordid white stripes along each side, and a broader one below the spricles, which are black, and another stripe along the middle of the venter. Thoracic feet, extremities of abdominal legs and anal legs jet black, shining. The body is also covered with sordid white hairs. Length 32 mm.

We are requested to announce that the next meeting of the Club will be held at Cleveland, Ohio in the High School Building, beginning at 9 a.m., on Wednesday, the 15th of August. This date is a week earlier than that at first decided upon for the meeting of the A.A.A.S. As this location is central and convenient alike for both United States an Ontario Entomologists, it is expected that there will be a large attendence, and an interesting and enthusiastic meeting. All entomologists are requested to come prepared to aid in the matter; those who desire to present papers should send to the Secretary, Prof. A.J. Cook, Agricultural College, Mich., the subject they propose to discuss in order that it may be announced in the programme.
