In the part of Mr. Strecker's Lepidoptera, Indeigenous and Exotic, dated Feb. 22nd, 1875, is the description, and on the accompanying plate on excellent figure, of this species from a female sent to that author by the late Mr. Caulfield, and which was probably taken in the previous summer. The speciment was found in Phillips Square, which is about two miles from its nearest known locality, by the caretaker, from whom it passed to the taxidermist of Natural History Society, who gave it to Mr. Caulfield.

Mr. Andrew Bolter, of Chicago, has kindly sent me the type of this species for examination. It proves to belong to none of our families of Bombyces, as I had suspected.

Among the first insects which I found upon my arrival in the Mesilla Valley of New Mexico, in March, 1891, was a small sawfly. My notes on this species were made as follows at the time:-

March, 1891.—Specimens of a small yellowish and brownish sawfly were found quite abundant flying everywhere from middle to last of March. They were not found on any plant, but their numbers make it probable that they will turn up as injurious to some plant.

Preparatory to the publication of a list of the Coleoptera of this vicinity, it has been thought proper to characterize and name the following forms:-

Bembidium postfasciatum.—Coppery-bronzed, dark beneath, elytra pallid, two dark fasciæ. Head convex, impunctate, longitudinally impressed on each side between the eyes, coppery-bronzed; antennæ wit three basal joints pale, the others fuscous; thorax quadrate, base and length equal, wider at middle, base truncate, basal striæ double, hind angles rectungular, carinate, dorsal line deep, coppery-bronzed, often tinted greein in the basal impressions; elytra pallid, silvery white in life, elongate oval, broadly deeply impressed transversely behind scutellum, deeply striate, striæ dilated before middle and coarsely punctured, punctures finer towards apex, intervals convex, third bipunctate, a broad undulated dark fascia behind middle, another before apex sometimes interrupted at the suture and sides; underside dark, oftern with a greenish reflection; legs entirely pallid.

I have just received a specimen of an Erebus odora, which was captured last Wednesday evening (Sept. 27th) in the lecture-room of the first united presbyterian Church, in the city of Allegheny, where its appearance caused no little consternation among the devout “mothers in Israel” who were at prayer meeting, and who thought it was a bat, of which evil things are said by the unsophisticated.

One hot afternoon in the early part of August, 1893, while out collecting, I found a large web of the Fall Web-Worm (Hyphantriacunea, Drury), on a young apple tree. Reaching up to cut off the twigs to which the web was attached, my attention was attarcted by an unusual disturbance among the immates of the web. Closer insepection revealed the fact that a medium-sized Ichneumon fly had intruded within the family circle, and was proving herself a most unwelcome visitor. Tearing into the web with her feet she would force her way along until she arrived under the skeletonized leaves upon which the larvæ were resting and through which they were plainly visible.

Most modern European writers follow Tulleburg in placing all the Collembola in the family Poduridœ, and including the Poduridœ, Lipuridœ and Anouridœ of Lubbock in the subfamily Lipurinœ. It would seem more natural to restrict the name Poduridœ to those genera bearing the saltatory apparatus on the antepenultimate abdominal segment, instead of the penultimate, and then to include those genera in which the saltatorial apparatus is wanting under the name Aphoruridœ*

In an original memoir on the Zygaenidœ, published by the Essex Institute, Dr. Packard explained the relation of Castnia and allied genera to the European genus Zygaena, and contended for the solidarity of the group as the equivalent of the large family of Bombycidæ in the Latreillean sense. The view, advocated by Agassiz, that form was a family criterion, not only form in general, but form of parts undelying form in general, obtained.

In our last number, pages 272–5, the lists of Coleoptera were unfortunately disarranged in making up the forms.
