A list of all the known species of terrestrial Arthropods of the Labrador coast may prove convenient as a starting point for future investigations. Hence I have, besides enumerationg the species of ohter groups, revised the list of Lepidoptera—Mr. Sucdder kindly contributing the list of butterflies. For changes in the names of the Torticidæ I am indebted to Prof. C.H. Fernald's excellent catalogue of the Torticidæ of the United States.

It has been a fortunate thing for the study of butteflies in this country that the earlier students were those who devoted themselves very largely to the natural history of these insects rather than to their systematic or descriptive study. It was indeed a natural and healty result of the proverty of extrenal resources in earlier times; and I have though that it would not be devoid of interest to present a few facts concerning the life and iindustry of one of these earlier naturalists, who worked to such good purpose and accomplished so much, under circumstances that would now seem very forbidding.

A few years since I described a colony of Spanner caterpillars (Geometridœ) belonging to an undeterminded species, and the description appeared afterwards in this journal. These larvæ were remarkable for their mimicry, in color and shape and attitude, of dead leaves. There could be no question that they belonged to the category of protective appearance, to which so many green and brown tinted larvæ belong, which share these “cosmical color.s”

On November 1st, 1887, I took in this locality (Swift Creek, near West Cliff,) an example of Nathalis iole, and was thereby led to examine its characters. The general colour of the upperside of this insect is pale yellow. The primaries are marked with pale black (if one may use such a term,) after teh manner described in the text books, and the upper margins of the secondaries also present a black patch, covering the area which is normally overlapped by the primaries.

A copy of a German translation of Ross's Second Voyage lately fell into my hands, and I make the following bibligraphical note upon the descriptions of Lepidoptera there given. The translation is by Julius, Graf von der Gröben, Lieutenant in K. Pr. Reg. Garde du corps, and the thrid part or volume in published in Berlin, 1836. This volume (8 Vo.) contains the natural history, the descriptions of the Lepidoptera occupying pages 238 to 255 inclusive.

Anthocharis Pima

Male—Expands 1.75 inch.

Upper side yellow; the bases of wings dusted black; primaries have the basal half of costa white, crossed by dark brown streaks; the apex also edged white on both margins, and next this is series of five large, elongated, dark brown spots, almost confluent, filling the interspaces to second medium nervule, each sending a narrow projection to the margin; on the arc of black rectangular bar, the area between this and the apical spots and costal edge orange; fringes whitish; a few blackish hairs at the end of eacch nervule on secondaries.
