10 ETERUSIA; RHODOPSONA; PIDORUS. By Dr. K. Jokdan. 



semihyatina. P. semihyalina KoU. (2 a). Frons and a spot on the niesothoracical tegula reddish yellow, 4. and 



5. abdominal segments yellow above. Foiewing near the base with a band of vitreous spots and a large 

 vitreous patch bej^ond middle consisting of many spots. Hindwing with vitreous spot at base and a row 

 of 3 vitreous spots behind the apex of cell; on the underside a yellow spot in front of apex of cell. — 

 Kashmir, India, South China. Variable in the trojjical districts. 



7. Genus: X2terusia Hope. 



Korewing elongate. Antenna of d' long -pectinate, of ? dentate, except the last segments, which 

 bear also in ? long pectinations, giving the antenna the appearance of being clubbed. 2. and 3. radials of 

 forewing stalked. Sexes often ver\^ ditferent in pattern, the ?? in these cases being much paler and more 

 extended light in colour than the cTcf. These ?? remind one of Fulgoridae on account of the leathery 

 appearance of the wnngs. 



leptalina. E. leptalina Koll. (2a). Sexes dissimilar, cf: collar red, tegula of mesothorax yellow, underside 



of body grey-yellow. Wings greenish black, markings yellow; forewing with longitudinal streak at base, 

 an abbreviated, sometimes interrupted, transverse band in centre, and a dot ontside apex of cell ; hindwing 

 yellow from base to near apex of cell, the veins more or less black. Underside more extended yellow and 

 paler; hindwing almost entireh- pale yellow, bearing some black spots beyond cell. ? with tiie head and 

 sexpnnctata. coiiar red; abdomen ringed with fuscous. In the ?-f. sexpunctata Walk. (= octopunctata Moschl.) (2a) 

 both wings are yellow, the hindwing being occasional^ whitish, and bear usually one or several sharply 

 marked black spots. In ?-f. leptalina Kol/. {= cicada Fldr., triliturata IVa/k.) (2 a) the forewing is more 

 or less extended fuscous between the veins. — Central and West China, Kashmir, Afghanistan, North -West 

 and North India. 



elizabetha. E. elizabctha Walk. {z= dirupta Walk., microcephala Fldr.) (2h). cf : head and collar green; under- 



side of body pale yellow; markings of wings yellow, paler below; forewing with longitudinal stripe at base, 

 two spots in centre, a larger spot distally of cell and several submarginal spots; central area of hindwing 

 yellow, irregulary divided by the dark veins. ? very similar to ?-f. sexpiou-fafa of E. hpfaVnia, but head and 

 collar not red. — Yang-tse-kiang, from Shanghai westwards to Ta-tsien-lu, found in June, July and August. 



tricolor. E. tricolor Hope (2 b). Sexes similar. Green -black; antenna, head, part of back, some spots at 



apex of hindwing, as well as the veins in the distal portion of forewing below and the borders of the sub- 

 marginal spots metallic blue. Abdomen yellow, banded with blackish blue above in c?', below in ?. Forewing 

 with yellowish white spots: 1 at base, 2 proximally of centre, 1 distallj- of apex of cell and an irregular 

 submarginal series. Hindwing with a broad yellow band , which occupies nearly the whole hindmargin. — 

 West China, in June; common in North India. 



magnifica. E. magnifica Bllr. (2 b). Sexes similar. Like the preceding, paler, forewing with a band proximalh- 



of middle. Abdomen yellow above in d" and ?. — West China; common in North India.*) 



aeiiea. E. aedea L. (2 c). Sexes similar. Markings of both wings white, otherwise like uiagnifira. Perhaps 



aedea and niaynijka are mere colour-varieties of the same species. — Common in Central and West China, 

 Indian specimens being somewhat ditferent. 



8. Genus: Bhodopsona yev. nov.**) 



Antenna of cT and ? long -pectinate, bushy, pectinations remaining also in ? rather long at apex. 

 8. abdominal segment of cf and claspers long, these longer above than below, almost closed below. 

 Forewing with red stripe or for the greater part red. cT and ? similar in pattern. — India, China. 



costata. R. costata II '(///.■. (2 c). Black; head and collar red; a broad red costal streak on forewing, curving 



backwards at apex of cell, extending to hinder angle. — Common in West, Central, and North China, the 

 streak being yellowish red in West Chinese ¥?. 



nibiginosa. R. rubiginosa Leech (2 c). Forewing red, only the tip and a streak behind cell jjeing black. Pecti- 



nations of antenna \ery long; 2. and 3. radials of forewing separate. — West China, in the Tring-Museum 

 some specimens which were obtainad between Chungking and Mt. Omi (= Omei-Shan). 



9. Genus: Pidoriis Walk. 



Antenna of cf and ? pectinated. Forewing with white or j^ellow transverse band; hindwing uni- 

 colorous or with yellow spot or band. Claspers of cf truncate, widely open. Sexes similar. — Indo-Malayan, 

 northward to Japan and Gorea. 



) The figure is taken from an Indian specimen. Chinese individuals are paler yellow and agree with aedea in the 

 extent of black on the wings. 



") Name-type: coatata Walk.
