Young larva.—Body dark reddish, inclining to black; otherwise as in the following stage.

Before last moult.—Body black or reddish black, with eight longitudinal clear white stripes, as broad as the intervening spaces or broader, with the exception of the dorsal space. Beneath are three partly obsolete white lines, two of them interrupted by the legs. The head and cervical shield all dark mahogany red, as are also the abdominal feet, the bases of the thoracic feet and two spots on segments 4,5,10 and 11. Thoracic feet black.

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.

We ar glad to learn that Mr. John B. Smith, of the National Museum, Washington, has been appointed State Entomologist of New Jersey. He will enter upon his new duties on the first of April, and will reside at New Brunswick, N. J. While we congratulate the State upon securing the services of so eminenlty capable an entomologist, we trust that Mr. Smith will find his new work congenial and satisfactory, and its accessories lucrative and comfortable.

The following is a list of butterflies caught near Fort Qu'Appelle, Northwest Terr., by Mrs. Cora E. Rose and her two little sons. Mrs. Rose describes the locality as follows:—“Those sent were all caught within a radius of about half a mile, in the territory of Assiniboia, thirty miles north of an old Hudson Bay Post called Fort Qu'Appelle, and distant west from Winnipeg some three hundred and twenty-five miles; the only foliage is willow and poplar.”

will hold its first annual meeting in the City of Washington, D.C. on November 12th, 1889, at 11 o' a.m., in the Entomoloigcal rooms at the U.S. National Museum.

According to the resolution of the Association at the Toronto meeting, the annual meeting was to be held on the date and at the place where the Association of Agricultural Colleges and Experiment Stations should nex meet.

There exists no biography nor necrology of this excellent entomologist, as far as known to me, though he lived for thiry-nine years in the United States. I am much indebted to Dr. Geo. C. Horn for Zimmermann's notebook which, with his library, came into the hands of the late Dr. J.L. Leconte.

Only a very short abstract of the contents, which are written wholly in German, can be given. The entries begin with Zimmermann's earliest boyhood and end in 1843, followed by a few pages for 1865.

Now that the winter is well advanced and before many weeks are over spring will be upon us, it reminds me of many enquiries made during the last few years about the localities and dates of diurnals captured by me in the North-west in 1883 and 1884. These particulars are nearly all to be found at the National Museum of the Gelogical Museum at Ottawa, but for the benefit of those who may be visiting the North-west with a view to collecting diurnals, I propose to gie such information about the rarest species as my notes supply, and as my limited time will permit.

I have lately had on opportunity of examining bred specimens of the European Ochria ochracea(flavago). The clypeal tubercle may be felt with a fine pin or seen under the glass when the frontal scales are partly removed. We have two North American species agreeing with Ochria, viz., Sanzalitae, from California, and Buffaleonsis, from the east. With the former, the European species has a nearer resemblane externally; our eastern species differing much in colour.

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.

This new form was founded by my friend, Mr. James Behrens, of San Francisco, at Upper Soda Springs, Sisikiyou County, near Mount Shasta. The hind wings and abdomen are wanting, but the fore wings are present and in a very fair state fo presevation.

If all controversial writings were as happy as Mr. Ashmead's last, readers of the Canadian Entomologist would not regret the space occupied, and I am glad that one side of the controversy in interesting reading. I hope I may be allowed space to say that Mr. Ashmead admits in conversation that he has erred in his statement that my first publication of the description of Rileya was in Canadian Entomologist for Oct., 1888, as I have shown him the last page of Entomologica Americana for July 1888.

In reply to Mr. Smith's paper, somewhat inappropriately styled “Arctiidœ vs. Noctuidœ,” I would state that my origintal paper in Entom. Amer. on Certhosia had for its main object the pointing out of the errors contained in Mr. Smith's original description of the genus in the neuration. When these errors are corrected according to my statements (which latter in the main seem to be acknowledged by Mr. Smith as correct), the probability that the moth is an Arctian next to Uteheisa is weakened, and, as I have shown it is not a Lithosian, the chances are we must look for its position elsewhere.
