The expansion of the wings is about 1½ inches. The fore-wings are dark grey with bronzy reflections; there is a pale band on the termen, and several of the transverse lines are indicated by paler colouring, the two basal ones being often silvery; the orbicular is partly outlined with golden-white, and the claviform is wholly filled in with the same colour. The hind-wings are yellowish-grey, darker towards the termen.

Mr. Meyrick mentions a variety in which the characteristic golden-white discal spots on the fore-wings are absent. I have not yet had the good fortune to see this form, and think it must be a rare one.

The larva has twelve legs; it is much attenuated towards the head; its colour is pale green, darker on the back; there is a number of wavy white lines and dots on the larva, as well as a few isolated black dots and hairs. It feeds on geraniums, mint, bean, Scotch thistle, and many other garden plants and weeds. Its original food appears to have been the "potato plant" (Solarium aviculare); but now it only occurs on this shrub in uncultivated localities, where there is no European vegetation.

The pupa is enclosed in a cocoon of white silk, generally situated between two dead leaves on or near the ground.

The moth first appears about September, and continues abundant until the end of summer. In Nelson I have seen it in great profusion, hovering over various flowers in the evening, at which time it also occasionally endeavours to gain access to beehives. In the same locality I have met with the young larvæ in the middle of winter, so that there is probably a continuous succession of broods all the year through in favourable situations.

This insect is found in Australia, Pacific Islands, Africa, South Asia, South Europe, and occasionally in the South of England.[[22]]

Genus 3.—DASYPODIA, Gn.

"Eyes naked. Palpi with terminal joint very slender. Antennæ in male filiform, hardly pubescent. Thorax and abdomen not crested. Tarsi in male very much thickened, with dense scales (teste Guenée)."—(Meyrick.)

We have one species.
