The spots forming the outer band are smaller and near the margin. Besides these, the fore wings have one or two spots towards the upper margin and the hind wings, which are tailed, have a series of seven blue spotsorpatch- es, and near their hinder angle an eye-like spot of an orange colour, with a black centre. The under surface of both wings is paler, with the spots arranged nearly as above, excepting that those on the hind wings are tinted with orange. The body is black, with longitudinal rows of yellow spots. The wings, when spread, measure from three and a- half to four inches across. The caterpillars, when fresh from the egg, do not measure more than a tenth of an inch in length, are black with a broad white band across the middle, and another on the hinder segments, while the body is studded with small black projecting points. After the first skin is cast the white band is restricted to the sixth and seventh segments, and around the base of the black projecting points are spots of an orange colour, while low down on the sides is a row of white spots ; there are also two of the same colour on the top of the first segment, and a larger one on the hinder segment With each moult these caterpillars alter in colour and appearance, and before they are half grown the pro- jecting points, white band, and spots entirely disappear, the skin becomes smooth and of a delicate green colour, rather paler at the sides and whitish below, and each ring is crossed by a band composed of alternate black and }'ellow spots. When irritated they push forth, from a slit in the first segment of the body, a pair of soft, orange-coloured horns, united at their base, and shaped somewhat like the letter Y ; from these, when extended, a disagieeable odour is given off, which serves to defend t
