Aphrodite is a native of North America, (and not, I believe, of the European continent), the notion that the specimen had, either by accident or design, made its way across the Atlantic, and settled down, in a state of good preservation, as nearly as may be in the centre of our own island, is too improbable to be seriously entertained for a moment.

I regret that Mr Walhouse omitted to record the precise date of the capture of Arg Aphrodite ; but as it occurred during the season when Arg Paphia was on the wing, it must, most probably, have been in July or August.

We may conclude also that the period of flight, with both insects, is the same.

The accompanying figures supersede the necessity of entering into a minute description of the insect.

It is larger than Arggnnis Paphia, and of the same rich ful- vous colour, checkered and spotted with black, on the upper surface.
