CERURA; DICRANURA. By M. Gaede. 
bipunda. P. bipuncta Rothsch. (84 b). Varying between pale green and dark green, with 3 notched brown dark- 
edged bands. The name is incorrect, as also the original figure shows 3 dots, the anterior one (of styphlopis) 
and the interior horizontal one of the type being white, whereas in other specimens they are black, finely edged 
with white, the fourth spot may also be present. New Guinea, Russel I., up to 1600 m. 
57. Genus: Centra Schrk. 
Palpi short. Antennae with long pectinations as far as the tips, in the C shorter pectinated. Forewing 
broad. Vein 5 far in front, 6 and 7 + 8 + 9 from the apex of the accessory cell, 10 close beside it. Type: 
furcula Schrk. from Europe. As to further particulars about the genus, cf. Vol. II, p. 285, and vol. XIV, p. 408. 
lilurata. C. liturata Wkr. (= damodara Mr., argentea Fldr.) (84 c). Forewing silvery white, sometimes also 
dusted with yellowish. Interior line double, filled with grey or olive brown, rarely absent. Behind it many 
lunular lines, a spot at the cross-vein, and a subapical spot. Veins at the ends black. Hindwing white, sometimes 
strongly darkened. 42—60 mm. India and Indo-China. 
wisei. C. wise! Swh. is similar to liturata, but larger. On the forewing there are at the margin between the 
veins intense black spots which extend far inwards between veins 1 and 4 or form double spots there. Khasia 
kandyia. Hills, Sunda Is. — kandyia Mr., from Ceylon, only shows small marginal spots and may be a separate species. 
— Dr. Bering of the Berlin Museum has ascertained, by examining the genitals, that there are 4 similar species, 
i. e. two with black streaks and two with marginal spots. But as there is nothing known about the genitals 
of the species described by English authors and of the 4 following species or forms of Matsumura, we cannot 
say anything about novelties or synonyms. 
baibarana C. baibarana Mats. On the forewing the interior band is not so strongly notched, its distal border from 
the submedian fold obliquely outwards to the inner margin, not vertical to it. From veins 4 to 8 a distinct 
black marginal line, veins 2—7 with black ends. Hindwing brownish, at the base lighter, with 2 dark obsolete 
subrosea. postmedian bands. $ 60 mm. Formosa. - subrosea Mats, resembles baibarana, but the ground-colour is 
somewhat pink, on the forewing 4 exterior lines are distinct, the marginal ones of these lines behind the cell 
more notched, the median ones only incurved. $ 62 mm. Formosa. — Whereas these two forms are almost 
arikana. exactly like liturata, arikana Mats, is somewhat more distinguished from it by the absence of the black marginal 
tattakana. line, the veins being black, but not quite to the margin. $ Mi mm - Formosa. - tattakana Mats, is very similar 
to the form wisei Swh. which name would eventually be prior. $ 72 mm. Formosa. — A form Dicranura 
formosana Mats, is mentioned, but I have not found its description. 
C. prasana Mr. Similar to liturata, but the body white. On the forewing the dark interior and exterior 
bands are filled with pale, the latter being interrupted. Without dentate lines. $ 40 mm. Northern Bengal. 
6 
C. sangaica Mr. Ground-colour reddish-grey. Basal area as in liturata. The second band extends 
through the disc and is paler. The dentate lines are here also absent. In both wings black marginal spots. 
Body with greyish-black bands. <$ 38 mm. Shanghai. 
C. multipunctata B.-Bak. (84 d). Thorax and forewing white with bluish-black spots being small in 
taia. the <+ larger in the $, the exterior ones almost forming a band. Hindwing of $ white, of $ smoky brown, only 
the base white. 65—85 mm. New South Wales, New Guinea, Amboina, Burn. 
australis. C. australis Scott (84 d). Similar to multipunctata, but with the interior band of liturata, which is 
broken up into black-edged olive brown spots. $ 60 mm. Australia. 
ejecta. C. ejecta Front. Forewing white, scantily dusted, with a pink hue and black spots at the costal margin. 
Interior line indistinct. Ring-macula and reniform macula finely edged, the former inside with a black longi- 
tundinal streak. The double notched median line begins between the maculae and extends to behind the middle 
of the inner margin. Exterior line strong, very much incurved, then obliquely to the anal angle. Behind it 2 
feebler lines and marginal spots. Hindwing white. G 40 mm. Key Is. 
dohertyi. C. dohertyi Drc. A specimen from Penang resembling the description, is a Cossida. 
C. melanoglypta Low., from Southern Australia, with an undulating margin in both wings is certainly 
no Gerura and probably neither a Notodontida.

58. Genus: Dicranura Bsd. 
Separated from Gerura only by the scheme of markings. Type: vinula L. from Europe. Cf. Vol. II, p. 287. 
Mmalaya- O. himalayana Mr. Similar to erminea Esp. figured in Vol. II, pi. 49 c, but the light partition-line of 
na the dark area at the inner margin is absent and replaced by a feeble dark one. 60—80 mm. North India. —
