An oversight (ante p. 167, line 27) leads me to state that it is in the Aporid section of the Pierinœ that the pupa has the adbominal segments 5 and 6 moveable, whilst in the Pierids proper only 5 is moveable. The Pieridi have until now alwasy included the Apord section; as a matter of fact, many Europen systematists have placed our Aporia crataegi in the genus Pieris.

The larvæ of two species of Arachnis, from Mexico, were given to me by Mr. Jacob Doll. They are the following:-

Arachnis aulea, Geyer.

Egg.—Shape of two-thirds of a sphere, with flat base. Shining, pearly, irirdescent. Diameter, .6 mm. The reticulations are rounded, moderately distinct, of quite uniform size, but smaller at apex. On the angles of the reticulations a series of short, stiff spines (½inch objective).

My esteemed friend, Dr. L. Gundlach, has left to me the task of describing several nerv Bombyces, which he discovered within the last few years in Cuba. Some of the specimens which are uniques, are, unfortunately, in such a poor state that a thorough description was well-nigh impossible. In one case I had to refrain entirely, on account of the dilapidated condition of the insect. All the types belong to the Museo Cubano Zoologico de Gundlach, lately acquired by the Spanish Government.

Expanse of wings one and one-fourth inches. Length of body sixtenths of an inch. Head and antennæ black. Thorax, above black bordered with white, beneath white. Legs white. Wings white, satiny, translucent. Primaries have a slight tinge of yellow. On the costa, near the middle, are two black or drk brown blotches; below these, towards the inner margin, are two other blotches, sometimes united—the whole forming a broken, transverse band.

During the winter of 1891–2, I received from Miss Morton, of Newburgh, N, Y., six cocoons of P. columbia, which she had reared from ova, received from one of her correspondents in Ann Arbor, Mich. They were the first cocoons of that moth I had seen. Their extremely smali size as compared with Cecropia, their natty appearance and dark colour, relieved by flecks of white silk, was quite novel to me, so I frequently showed them to visitors.

Syntomis hilda, n. sp.

♂.— Antennæ, head and throax black; first and fifth segments of the abdomen white, the rest metallic green; primaries dark brown with three ovate vitreous sports on the sub-apical area; discal space has two large triangular vitreous spots, the largest being near the inner margin.

A single fly, bred from a larva on oak at Boston, Mass., appears to belong to this species. The fly differs from Mr. Cresson's description in that all the tarsi are blackish; the abdomen above is largely blackish; there is no luteous tint discernible on the laterl margin of middle lobe of mesothorax; the anterior and posterior margins of the luteous stigma are blackish and the veins are nearly black.

Lake Worth is an elongated bay connected with the ocean, two and one-half miles from its northern end, and separated from it by a narrow elevated stirp of land, varying in width from two hundered to nine hundred yards. Its length is about 20 miles, while in width it averages about thirteen hundred yards.

My type is in the British Museum, where it has been examined by M. Ragonot, who compares it in his description with the European D. abietrella, from which this authority finds it to differ structurally. The figure in M. Ragonot's magnificent work seems to me excellent. I take this occasion to express my dissent from the classifaction adopted in the Philadelphia List.

This moth was rather common at Ithaca, New york, in 1892 and 1893. The moths fly in the afternoon and early evening of the latter part of June and most of July. They are attracted to lights to some extent, but those taken are mostly males. The eggs are laid in clusters upon blades of grass. They are firmly attached to the leaf, and the five or six in a cluster over-lap more or less.

After the long, steady and severe winter we had in this locality, every one hoped for an early spring; but in that we were disappointed, things generally being no futher advanced at the end of May than they usually are in the middle. June came in warm, but with such continuous rains as to prevent collecting to any extent.

A practical way of procuring moths's eggs under my observation last season and the season before, though an Arctia ornata ♂ that I sent to Mr. Dyar while he was in Portland, Oregon.

When I take an Arctia ornata ♀, and she is ready to lay eggs, the moment she shows signs of being stupefied in the Cyanide bottle I take her out, close the wings over her back, and place her in a paper envelope; as soon as she revives, she will commence to scratch the paper with her legs; I then shake the envelope, and if she has given up some eggs, I take them out, give her another dose of Cyanide fumes, and when she revives a second time I have found as many as 125 eggs in the paper.

I have suggested in “Papilio” that this South American species belongs to Copidryas, and is congeneric with our C. Gloveri. Berg's original description says of the frontal structure:- “Fronte valde prominenti, supra cornu complanato depressione declivi marginata fuscaornata.” This character agrees well with Copidryas, but not with Eudryas, in which latter the front is not horned.

On page 224 of Canadian Entomologist, Volume XXVI., Mr. Herman Strecker has some remarks on Chionobas, in which I am glad to say, he supports my views, except in two points. First, with regard to the subhyalina of Curits, I cannot coceive on what grounds he supposes that the description of subhyalina refers to Erebia fasciata, and as W. H. Edwards's suggestion that the example from Guenée's collection sent to me by Oberthur as the type of subhyalina is not really so, rests on no evidence whatever; I still maintain that subhyalina is the proper name for the insect hitherto called crambis, Freyer, found, as far as we know at present, from Newfoundland along the Labrador coast to Hudson's Straits and other parts of Eastern Arctic America.

So far as I have present references Berg is the first to use again the term Euthisantoia for Eudryas unio an I have shown, not congeneric with unio, but belongs to my genus Copidryas. More recently Neumoegen & Dyar use Euthisanotia and cite Boisduval's Eudryas as a synonym.

On July 24th, 1893, I received a number of puapæ of Exilis, made of the road, and three nearly adult larvæ (after the last moult), sent me by Mr. T.D.A. Cockerell, at Las Cruces, New Mexico, and found on flowers of Atripex canescens, of which a plentiful supply was also sent.

The numbering is continued from page 193.

(13.) Tachardia cornuta, n. sp.—♀scales crowded on the stems of the plant, lively red-brown in colour, smooth and rather shiny, subtranslucent; elevated so as to form in outline a triangle, the base of which is greater than either side viewed from one side, but with the sides greater than the base when the scale is viewed from one end.

Egg.—On September 2nd, 1893, it was found back of Napa College Laboratory, laid singly on the stem of the flower of wild anise. Nearly spherical, base slightly indented, smooth, bluish-white with grayish shade on one side. Diameter, 1.245 mm. It hatched September 5th, bursting the shell in halves; the shell was white.

R. arefactus, n. sp.

The galls are dense, corky enlargements of small shoots, usually close to the stem from which the shoot arises, and the shoot is usually dead beyond the gall when the latter is mature. The galls are irregular in shape, vary from one-half to seven-eights of an inch in diameter, and are polythalamous.

The following notes are intended to throw further light on the affinities of certain little-known species, which I have lately examined:-

(1.) Chionaspis major, Ckll.—Found on Heliotrope at Antigua by Mr. C. A. Barber. The ♀ resembles that of Diaspis lanatus, but may be distinguished from it without difficulty.
