PERINA; TOPOMESA; DACTYLORHYNCHA; PORTHESIA. By Dr. E. Strand. 
35. Genus: JPerina Wkr. 
This genus composed of but 2 very similar species has been described more minutely in Vol. II,-on 
p. 134. The imagines are common, and the larvae, with a variegated dorsum and covered with numerous brushes, 
are frequently met with on fig-trees shading the streets of tropical towns. 
pura. P. pura Wkr. (39 g) from North India to Calcutta and Cachar differs from nuda only by the head, 
thorax and abdomen being whitish and the scaled surfaces of the wings white with a brownish hue. $ much lighter 
than that of nuda. 30, $ 40 mm. 
nuda. P. nuda F. (= subtineta, basalis, combinata Wkr.) (Vol. II, t. 21 d) has already been dealt with 
in the palearctic part, Vol. II, p. 134, where also the larva is described. The latter is figured — unfortunately 
not coloured —- in Ind. Mus. Notes III, t. II, fig. 2 d. It lives on Ficus indicus and F. religiosa, and is 
like the pupa magnificently coloured. — Flying time September and October. — The species also occurs in 
Formosa, according to statements by Dr. Seitz it is common in Hongkong and reaches the palearctic region 
in China and Japan. 
36. Genus: Topomesa Wkr. 
Forewing broad, subtriangular, with a sharp apex and a midway indented margin, the bindwing forming 
an angle at vein 1 b. Palpi long and obliquely upturned. Antennae with long combs. Posterior tibiae quadri- 
calcarate. In the forewing 6 rises behind the angle, 8 + 9 -f 10 on a long footstalk, and from the middle of 
this footstalk rises 7, 8 terminates into the margin. In the hindwing 6 and 7 rise from the angle, and the trans¬ 
verse, very little oblique discocellular is midway deeply indented or perhaps broken. The genus is exclusively 
Indian. 
subinanis. T. subinanis Wkr. (39 b). sulphureous. Frons and palpi red-brown, antennae with brown 
pinnae. Forewing with a red-brown spot beyond the lower angle of the cell and some marginal marks. Hindwing 
with a red-brown marginal spot near the anal angle. Expanse of wings: 42 to 56 mm. Java, Borneo, Singapore, 
Tenasserim. 
discolor. T. discolor Hmps. (39 g). <$: distinguished from subinanis by the very pale reddish ochreous colouring; 
thorax and base of forewing are suffused with whitish, the forewing strewn with silvery scales, costa reddish, 
a blurred dark spot on the upper discocellular instead of a spot beyond the lower cell-angle, the margin behind 
the apex is much more excised and angular at vein 4. Expanse of wings: 36 mm. Ceylon. 
lerwa. T. lerwa Swinh. <$: body white, antennae and head brownish. Wings yellowish, the forewing lightest, 
with a brown moon-spot at the cell-end, the costal line and partly the marginal line reddish. Hindwing uni¬ 
coloured. Fringes of all the wings reddish. Body beneath whitish, legs reddish. — $: forewing dusted olive-brow¬ 
nish, in the middle and at the margin darkest, the margin angular at vein 4. Under surface ochreous. Expanse 
of wings: 34,3 mm. Karwar, flying in September and October. 
37. Genus: Daetylorliyncha Hmps. 
Distinguished by very long, thin, obliquely porrect palpi the terminal joint of which, however, is very 
short. Antennae long, with long combs. Spurs long. In the forewing 6 rises about from the middle of the 
discocellular, 7 from the angle, 8 +9 -f- 10 on a rather long footstalk, scarcely touching 7 at the base. 
luteifascia. D. luteifascia Hmps. (44 f). The palpi do not extend much beyond the frons. blackish-brown. 
Forewing with a narrow orange-yellow costal band and a broader anal-marginal band, as well as with very 
indistinct ante- and postmedian lines. Beneath lighter. Expanse of wings: 28 mm. Burma. 
pallida. D. pallida Hmps. (47 c). $: uni-colourecl pale silky greyish-brown, forewing with some dark marginal 
marks below the apex. Pinnae dark. Expanse of wings: 28 mm. India, Nilgiris. 
38. Genus: Portliesia Steph. 
This genus composed of numerous species is easily discernible from Euproctis, to which it is otherwise 
closely allied, by the absence of vein 5 on the hindwing. It is distributed over the whole old world, and many 
occur in great numbers. The hair of the larvae on being touched often cause an inflammation of the skin.
