64 AGYLLA: CHRYSORABDIA. By Dr. A. Si;iT/.. 



26. Genus: Agylla Walk. 



This gonus is already closely allied to true Lithosia. The palpi mostly project only half as far as 

 those of Apisioski; head smaller, frons flat, antennae long, often with fairly long pectinations. Thorax 

 almost globular; tibiae with moderate spurs; abdomen clothed with rough hair. The forewing of the 

 Palearctic species elongate, linear, but lanceolate in some Exotics, and too small in comparison with the 

 huge hindwing; in the (J(J sometime with patches of hair. Over 50 species are placed in this genus, which 

 were formerly scattered over many genera, and are distributed over both hemisj)heres. The greater number 

 of species inhabit the Andes, a smaller numl)er the Himalayas. 



sinensis. A, sinensis Leech (12 e). Recalling 0. quadra in colour and markings, light yellow with 2 black 



dots on th(! forewing, but tlu^ spots only half as largo and the upper one not at the costa, but below it 

 in the cell. In West China. 



prasina. A. prasina Moure. This remarkable moth, from Kashmir, slightly resembles Hypsids, especially 



Macrohrochis gigas, which is much mors extended black. Size of $ of 0. quadra, bodj- and wings white, 

 but with strong metallic blue markings, the forewing being shaded from the maigins inwards, and traversed 

 by the dark glossy metallic l)lue veins, while the hindwing is white with a grey-black apex. Kangra, Dal- 

 housie, distributed in the Indian Himalayas to Sikkini. 



liltatd. A. vittata Leech (12 f). The species is well characterised by the yellow longitudinal stripe which 



traverses the dark blue-grey forewing; costa and collar are also pale yellow, as well as the hindwing. 

 In this longitudinal band of the forewing the moth resembles a group of Indian species belonging to the 

 following genus. North China; the form does not appear to bo common. 



albilinis. A. albifinis Walk. (12 f). Dark grey-brown, a large disc-shaped spot at the apex of the forewing, 



and a narrower band at the apex of the hindwing white. Not rare in the whole of the Western Hima- 

 layas from Kashmir far into the Indian territory. In the eastern Himalayas the species is represented by 

 a similar moth, apicaUs Moore, with more intense colouring, which does not, however, reach the Pale- 

 arctic region. 



pallens. A. pallens Hamps. (12 f). This moth, which is unknown to me in nature, is among the largest 



species, and has a very broad lanceolate-rotundato forewing. The colouring is very remarkable : abdomen and 

 hindwing are sooty grey, but the forewing light ivory with dark costal stripe, the colouring being reversed as 

 compared with that of most of the following species, which have a dark forewing with light costa. In the 

 North- Western Himalayas to Kashmir. 



gifjantea. A. gigantea Oherth. (12 a). Almost as large as the cj of 0. quadra; both wings uniformly iron-grey, 



shghtly tinged witli yellowish red; the forewing has a bright yellow costal stripe extending as far as the 

 apex. Singly in AmurUiiid, on Askold and in Japan, caught in July at the lamp by Graesek. 



collitoides. A. coilitoides Bull, {ii a). Larger and darker than gigantea, forewing glossy black-grey, the costal 



stripe broader and lighter; the collar bright orange. In Amurland (Hampsox), as well as especially 

 Japan. I only caught the moth once, near Yokohama, at the end of July; it does not appear to be 

 common. 



posllusea. A. postfusca Hamps. (12 e). Like a small form of the preceding, being described as such. The 



costal stripe narrows towards the ajjex, whm-ir it almost disappears. Kashmir and Tiliet, probably also on 

 Indian territory. 



holochrea. A. holochrea Hamps. Pale ochreous; tips of palpi, antenna, femoral stripes, tibiae and tarsi dark 



brown; underside of forewing suffused with brown with the exception of flu- marginal area. Chang- Yang. 



27. Genus: Chrysovabdia Butl 



Four species, which are alhed to Agijlla vittata with regard to colour and markings, have been 

 separated from the preceding genus on account of peculiarities in the venation. All the species have the 

 forewing longitudinally striped. Two species are Indian, two Palearctic. 



biiitta. C. bivitta Walk. (= disjuncta Moore) (12 f). As large as 0. quadra; the light yellow colour pre- 



dominates on the forewing, the dark metallic glossy dark blue longitudinal stripes lieing obsolescent in the 

 disc and only distinct in the outer marginal iirea. The ce)stal streak is broad(ir in the $ than in the ^J. 

 Kashmir, widely distributed in the Himalayas, also on Indian territory.
