Blackish brown ; spots and markings golden yellow, not gilded ; fore wing with a small spot subbasal, two large spots medial, the lower one the larger, and two discal, the largest of all; hind wing golden yellow, with a deep costal and marginal band, the latter attenuated to the hinder angle ; front of head, sides of eyes, collar, spots on fore and hind part of thorax, segmental bands of abdomen, all golden yellow; underside, wings as above, legs marked with golden yellow, and the segmental bands of the abdomen completely encircling it.

Most nearly allied to S. pfeifferi from Sumatra, differs in the pattern of the yellow spots on both wings; the fore wing having a single spot only before the apex, while the lower outer spot on the posterior margin is narrow and elongated obliquely outwards; on the hind wing the yellow spot extends through the cell, and is also deeply indented from its outer edge to the median vein. NOTIOPTERA PROPERTA, n. sp. (Plate XLIII. fig. 6.) Deep black; antennse long, two thirds of the length of the fore wings ; shaft glistening, pectinated from the base to the tips in both sexes, but three times broader in the male than in the female ; fore wings with two bands of white hyaline streaks-first medial, consisting of five, the other discal, consisting of four, the lowest one broadest and more rounded. Hind wings with a long suffused semihyaline whitish subcostal streak from the base to near the apex, a central short median streak also from tbe base, and two or three other faint, scarcely visible streaks adjacent, and two discal hyaline spots close together, the lower one much the larger ; thorax and abdomen deep black, with a bluish sheen with bright gilded golden-yellow bands ; but in three perfect examples before me, two males and one female, all taken in the same month, at the same place, these bands all differ ; one male has a broad collar, a large spot in the centre of the thorax, and the two penultimate segments of the abdomen all bright golden, gilded yellow, with this colour running up some distance on each side; the female has the thorax-spot absent, and the other male has the thorax-spot and collar both absent, but in all other respects they are identical.
