very much curved distal margin of the hindwing. The total colouring is somewhat similar to the American 
Perigouia, which resemblance is increased by the similar shape of the wings and the abdominal end being 
somewhat like a fish-tail. In the colouring this genus and the following genera likewise resemble the said 
American genus. 
C. decolor Wkr. (62 c). Unicoloured dark red-brown, forewing with a fine dark central dot and behind 
it a faded dark transverse shadow. Between the latter and the marginal shadow the centre of the marginal 
area is feebly lighter. North India. — From the North-Indian form specimens from Masuri on the southern 
slopes of the Himalaya have been separated as: pallens Jord. Large, body, and interior half of forewing wood- 
brown with a faint rust-coloured tint; distal half of forewing with a pale sepia tint. Marking as in typical 
decolor, but the total colouring much lighter. — In Southern China and the Shan States the more monotonous 
form uniformis Mell occurs, in which there are hardly any traces of the transverse lines and shadows of the 
forewing. 1 cannot decide whether formosana. Wil., which is unknown to me and is doubtfully combined 
with Cypa by its author, belongs to this place. It is described to be violettish-grey, intermixed with brown 
scales, with 5 dark brown transverse lines, the fifth of which is undulate. Somewhat larger; described from 
Formosa. euroa E. & J. (68 c) is likewise larger, with broader wings, more slate-coloured, with a more 
regular margin of the forewing. New Guinea. - ferruginea Wkr. , from Ceylon, the margin of the female forewing 
is not lobate at all, but only convex in the centre. —- The larva lives on oaks; it is green, exterior somewhat 
like that of 31. tiliae , also with a pointed vertex, but a dark dorsal line and duller oblicpie stripes; it also lacks 
the rust-coloured anal spot. — Not rare in Sikkim; the ground-colour of the larva varies according to the colour 
of the leaves of the kind of oaks on which it lives. 
31. Genus: ^isieriniSmltis Huwe. 
Very near to the preceding genus with which it was formerly united. Separated by the proboscis not 
being hunched at the base, by the short last joint and the longer penultimate joint of the antenna, as well as 
the more strongly developed lateral hairtufts at the abdominal end, owing to which the tricuspid shape of it 
is more distinctly visible. 
S. perversa Eothsch. (2 = olivacea Rothsch.) (62 c) is somewhat larger than Cypa decolor-, the anal angle 
of the fore wing is more pointed. Marking brighter, hindwing cinnamon-red, with a blackish submarginal band. 
Sikkim, Assam. 
S. pallidus Mell. Size and shape very similar to that of perversa, but much more variegated; forewing 
light ochreous with darker brown antemedian and postmedian bands which are connected in the middle by a 
broad shadow. The marginal area of the forewing is also marked in a bright brown colour, and the hindwing 
exhibits beside the black submarginal band a dark spot at the cell-end. — Larva dull greyish-green or discoloured 
reddish, with a very long frontal apex and dull, light green oblique streaks; horn long and thin, straight. 
On Castanopsis hystrix. Kwang-tung, apparently local. 
S. chinensis R. db J. is very similar to C. decolor (62 c), the margin of the forewing verj" much 
indented; apex of hindwing very round, and particularly below the apex convace; forewing broader than 
in decolor, with 4 transverse lines. Hindwing bright rust-coloured, beneath with very distinct discal lines. 
This form is the summer generation. In specimens of the cold season the forewing is traversed by distinct 
and often very distinct dark transverse bands; this is the form fasciosa 31ell. — Larva green or red, sometimes 
across the dorsum with bright dark or light spots; on the sides of the dorsum fine yellow longitudinal stripes 
into which the thin oblique streaks terminate. On Liquidambar formosana. The resting imago keeps its wings 
spread out and the abdominal end raised, like Mim. tiliae. - Southern China; also in West China, though more 
in its Indo-Australian region, the species probably passes over to palaearctic districts. R. Mell founded the 
genus Amorphulus upon this species. 
S. dohrni R. <£.• J. (62 c) is still smaller than decolor, the expanse being hardly more than 40 mm. Forewing 
bright red-brown, with a yellowish rust-coloured tint and a darker median area before which there is a light 
band bordered by the dark transverse lines. Before the anal angle a small dark spot bordered with light. 
Hindwing blackish or dark iron-grey. Sumatra. 
S. quadriptmctalus Huwe (56 C d) is very closely allied to dohrni as well as to the following species 
which it represents in Java. Separated from dohrni by the hindwing above being more brick-red than iron-grey. 
S. ferrartea Btlr. (56 C a). From Borneo; similar to quadripunctafus, but the margin of the forewing 
is not so deeply indented. Beneath the hindwing and the centre of the basal area of the forewing are rust- 
coloured. It occurs also in Malacca. 
32. Genus: l&egnmptera Hmps. 
Separated from the preceding genus by the hindwing being produced near the apex into a round lobe. 
Only two species are known.
