knew that it belonged to the Noctuina group, but that was all. So I sent an outline of its appearance to Mr. Fereday, the celebrated entomologist residing at Christchurch, enquiring if there were any such specimens in the Museum there, or if he knew of such a moth. From Mr. Fereday I received a very kind and full reply, that, while there were no specimens of this moth in the Canterbury Museum, he had one (a female) in his own possession, which had been taken some years ago at Nelson; and that, though rare, the perfect insect had been described, and was the Dasypodia selenophora of Guenee.[1]

And now for a brief description of the perfect insect.

Its size across, with wings extended, is 3″ 3‴; length of body, 1″ 3‴; the body thick, with 7 segments, but tapering downwards rapidly from its second segment almost to a point at the tail (not unlike, in this respect, those well-known British species of the Sphingidæ family, Smerinthus tiliæ, and Chærocampa porcellus), and densely covered with very long down. Antennæ, nearly 1″ long, slender and evenly attenuated, but not smooth, being apparently very finely aud regularly ringed and serrulated; legs, large and stout.

Its colour, on the other side, when living, was a sooty black; but after death it changed to a dark umber colour, with dark zig-zag and other markings on its wings (somewhat resembling those on the wings of the Emperor Moth, Saturnia pavonia-minor), and with a peculiar large and lustrous ocellated spot on each fore wing near the costa—in a line with the anal angle; all the wings are ciliated, bearing minute whitish dots at the extremities of the nerves or rays just within the margin. Its colour on the under side was ochrous or fulvous; the legs, amber-coloured below the knee, but its thighs were ochrous, and thickly covered with excessively long and waving down; its horns also were ochrous coloured but darker at their bases.

While living, it was a truly superb, rich, velvety-looking creature; presenting, too, when at rest, such a regular and graceful equi-triangular outline. The eyes on its wings had (if I may so express myself) a living look, much as the irises of the eyes of men and animals are sometimes drawn when represented under bright light. Those spots, or eyes, were all alike, black, but the two circular rims round each, and the lunate or triangular iris-pupil-like part within were shining lustrous and waxy, or as if strongly gummed. What with its fine moony eyes on its wings, and its long wavy down on its thighs, it well deserved its expressive name, both generic and specific. I could not help thanking its describer, for it is not often that we find so fit and distinguishing a name given in these modern
