2. Genus: Roeselia Hb 



■n. 



Generallj' more strongly l>ailt moths, resembling the preceding in the shape of tJie wings and facies. 

 Head proportionately smaller, forehead narrower, palpi often curved downwards or porrect; antennae long 

 and slender, ciliate or bi-pectinated in the (J. Wings broad, the apex being sometimes more pointed than 

 in Nolo, subcostal of forewing with 4 branches. Larva from brownish j-ellow to flosh-colour, on deci- 

 duous trees; it gnaws the epidermis from the leaves, so that a white, minutely reticulate spot results. 

 Pupa in a boat-shaped cocoon. About 50 species known to-day, which are distributed over all temperate 

 countries, with the exception of continental Africa, whence no form has been recorded; two species, 

 however, are known from Madagascar. 



R. togatulalis Hbn. (10 c). Forewing ashy grey, clouded and marked with a duller shade. A logahdalis. 

 blackish brown shadowy stripe, slightly convex on the outer side, runs through the centre and divides a 

 larger outer portion from a smaller inner one. Through the outer area runs a sinuous darker hne, which 

 is more distinct at the inner margin. In Central and Southern Europe, and Asia Minor, in sandy districts. 

 Larva bright foxy red, fairly densely covered with hairs; with dark lateral stripe. Until May on low 

 oak-bushes, in sunny spots. Pupa brown in a yellowish boat-shaped cocoon, attached to twigs of oaks. 

 The larva remains on the under.side of leaves by day, but easily betrays itself by the unmistakable reti- 

 culate transparent spot in the leaf. Moths at the end of June and July. They must be immediately 

 killed, as they begin to fly very soon after emerging from the chrysalis. 



R. albula Schiff. (= albulalis Hbn.) (10 c). Much smaller, scarcely half as large as the preceding, albida. 

 Ground-colour of forewing whitish, the median shadowy stripe narrower, forked towards the costa. Hind- 

 wing lighter at the base. In the $ the dark shadowy transverse line which runs through the centre of 

 the forewing is a little broader. In ab. fascialis Spul., the whole median area is darker and the marginal fascialis. 

 area grey-brown, the latter being traversed l)y the sharply defined light wavy Hne. The whole of Central 

 and South Europe, northward as far as Finland and Great Britain, throughout Northern Asia to Corea 

 and Japan, here on the main island and Kiushiu. — Larva pale yellowish brown, with shorter whitish 

 hairs and single long brown bristles, with double grey dorsal stripe and uninterrupted black subdorsal line. 

 Until June, on brambles and watermint; the moth in July, not common. 



R. scripta Moore (10 c). Only as large as albula and not unlike it in the markings, but the whole scripia. 

 insect almost uniformly slate-grey, slightly tinged with blue: the hindwing also unicolourous, not lighter 

 at the base as in albula, where the basal portion of the hindwing is almost white. Kashmir; the almost 

 inseparable form inscri'pta Moore occurs on Indian territory (^Sikkim). 



R. gigantula 8igr. {= gigas Butl.) (10 d). Twice as large as the two preceding species, similar to gigantula. 

 toyatulalis in shape and size, but the apex of forewing more pointed. Uniformly brownish grey in colour, 

 in the outer portion of the cell a dark, silky patch of raised scales, and similar smaller patches below the 

 costa near the base and before the apex of the forewing. The latter is traversed by several dark wavy 

 lines, which often portion off a slightly darker median area, which is broadened at the inner margin. 

 Near Amasia in Asia Minor, on the Ussuri, and in Japan on the main island and Hokkaido. 



R. maculata Sigr. (10 d). As large as gigantula and with similar markings, but the wings con- maculata. 

 siderably lighter; the outer area of the forewing almost dull white, distinctly traversed by dark dotted 

 lines beyond the centre and before the margin. The patch of raised scales in the cell very densely scaled, 

 dark and conspicuous, hindwing light grey, only darker towards the apex. In Amurland, on the Suifun 

 (DoERRiEs), and near Vladivostock (Graeser). 



R. nitida Hamps. (10 d). Size and shape as in the preceding, but basal and outer portions of the nitida. 

 forewing silvery white, a dark costal spot at the base and a brownish yellow transverse band before the 

 centre. Before the apex a smaller costal spot, from which proceeds a dark, dentate line which is inter- 

 rupted at the submedian and borders the marginal area, the latter being slightly tinged with copper- 

 colour and several times constricted. In Kashmir, also distributed over the Indian Himalayas. — Larva 

 according to Harford pale yellow, first and last segments orange; on segment 3 a double black spot 

 and a single one on segments 6, 10 and 11, a red hairy tuft behind the head. On Ilex, chewing the 

 edges of the leaves from underneath. At each change of skin the old skin remains hanging on the hairy 

 tuft behind the head. Pupa boat-shaped, attached to a twig and covered with l)its of bark, also the 

 red tuft of hair and the old head-capsules being used. 



R. fumosa BuU. (= strigulosa Stgr.) (10 d). Much smaller than the preceding forms. Dark grey, the fumosa. 

 darkly shaded median portion edged basally by a line which is convex at its inner side and finely dentate 

 at on its outer egde. Wavy lines, interrupted several times, traverse the median and marginal areas. 

 The raised patches of scales below the costa small and low. Amurland, Corea and main island of Japan. 

 In July, locally common. Larva in May and June on oaks (Graeser).
