1. Idiocerus Amœmus, n. sp.

Allied to I. suturalis, but smaller. Female of a uniform pale yellow colour, pronotum and scutellum tin gedwith fulvous or ferruginous, the former with a spot behind the inner angle of each eye and a median vitta, pale. Mesonotum with a black band bordering the scutellum, at least posteriorly; extreme tip of scutellum yellow. Elytra hyaline very slightly tinged with fulvous, becoming smoky toward the apex; nervures pale yellow. Wings hyaline, highly iridescent. Eyes rufous. Oviduct ferruginous.

This rather common moth seems to have attracted little attention, though the larvæ are voracious feeders. The moths may be seen flying over grass lands in the afternoon and early evening during June, July and August. They are attracted to lights but very little, only a few being taken in the trap-lanterns at* Ithaca, N.Y., in 1889.

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.

Egg.—Diameter, .035 inch by .02 inch high. Low conoidal, so much flattened as to be somewhat lens shaped, ribbed longitudinally with 37 striæ, 18 of which reach the micropyle, the striæ marked transversely with shallow cross striæ. Colour, dull olive. Duration of this period, 221 days.

After reading Mr. J. W. Tutt's note on page 47 of Can. Ent., I have looked over many of our species of Pieris and Anthocharis with the following result:-Our genus Pieris is probably entirely pure and congeneric with the European. The majority of our species of Anthocharis are congeneric with Euchloë cardamines, as figured by Mr. Tutt, but some species are different and should be removed from the genus. I have not examined seven of the species given in Prof. Smith's list, but those which I have seen separate in synoptic form as follows:-Mr. Tutt's nomenclature of the veins differs from that in use here, as will be seen by a comparison of my figures (Figures 9 and 10) of Anthocharis sara with the figures on page 47 of Can. Ent.

After a journey of ten miles over snow and snowbanks from four to eight feet deep, I arrived in the latter part of June, on my summer and fall collecting ground on the Fuloumne Meadows, which lie on the edge of the area wherein the high Sierra species of Lepidoptera are most numerous. The Paranassius was one of the first I began to collect, as the butterflies had just commenced to issue, and were flying in the grassy and shaded timber-covered portions of a rocky side hill slope.

On pp. 50—52 of the present volume of this journal, I described the new genus and species Calotarsa ornatipes, which I then supposed to be an anomalous syrphid. I am, now convinced that it is a platypezid. At the time of writing the paper, which was sent in in the fall of 1892, I overlooked the ciliate alulae of the wings, the apical spur of middle tibiæ, and the similarity of venation with the Platypezidæ.

My types of albalis, now in collection Brit. Mus., belong to a western species showing a charactertistic white downy surface of the primaries, obscuring the ornamentation. My single type of cloanthodies in coll. Graef, belongs to a smooth-winged from with distinct, sordid or brownishblack Cloantha-like markings. It does not appear that albalis has an European representative, while cloanthoides is not unlike Agrotis signifera, of which latter it may be the American representative.

In a previous paper there were given analytical tables to the genera of the families Aphorouridæ and Poduridæ; in the present paper will be found a table to the families and a table to the genera of the Entomobryidæ. The Smynthuridæ and Papiridæ are each represented by a single genus.
