308 CYSTIDIA; NEOLYTHRIA. By L. B. Protjt. 



gigantearia. Q. gigatltearia Leech (14 g) may be known by its great size, very pointed wings, postmedian band 



of spots much less angulated outwards than in tigrata, the spot on 3rd radial confluent with the large cell- 

 spot; sometimes all are confluent. Central and W. China. 



vonspurcata. 0. conspurcata Leech (14 g). Not so large as gigantearia, wings not quite so pomted, the spots less black, 



more extended, much more confused, not forming definite bands. Central and W. China. 

 B. Wings less narrow; 2nd subcostal of forewing long-stalked with 3r d— 5th. 



Iwrgcteaui. Q. largeteaui Oh. (14 h as largetaui) . Easily distinguished from tigrata by its shape and by the longer 



and very neatly chequered fringes, the dark spots of which scarcely encroach on the wing-margin. The yellow 

 is rather hghter than in tigrata, more glossy. Common in Central and W. China. 



languidatci. 0. languidata Walk. (14 h) differs in being mostly white, only a narrow distal border of the hind- 



wing remaining yellow. Postmedian band, except at costa, very far removed from cell-spot. Fringe of 

 forewing dark, of hindwing chequered. Japan and Omei-shan. Also in N. India. 



9. Genus: Cystidia i?&»- 



Face hairy or with loosely appressed scales. Palpus moderate or longish, 2nd joint long-haired 

 beneath. Antenna in ^ thickened towards the extremity. x4bdomen in ^ extremely long. Wings very long 

 and narrow. Forewing without fovea. All veins present. 



Larva {couaggaria) with rudimentary (non-functional) legs on the 4th and 5tli abdominal segments. 



Only a few species known, Japan to N. India. 



A. Face in the (J with long projecting hairs. Forewing with 2nd subcostal 



arising from cell. 



th-aUnice. c. stratotiiee Gram. (= agrionides Btlr.) (14 g). Easily distinguished, apart from the structure, by 



the single, acutely angulated black postmedian band. Distributed in Eastern Asia. 



ehinensis. C. chinensis S'winh. (= indrasana Leech nee Moore) (14 g) has the black so extended as to leave only 



solated spots of the white ground-colour. W. China: Mou-pm and Omei-shan. 



B. Face with appressed scales. Forewing with 2nd subcostal from stalk 



of 3rd— 5 th. 



louaggmria. C. couaggaria Ckien. (= eurypyle Men., eurymede Motsch., interruptaria Feld., lithosiaria Walk.) 



(14 h). Both wings with subbasal, median and postmedian black bands, the two latter confluent at costa of 

 both wings and hindmargm of forewing. Sometimes the black is greatly extended, covering most of the surface. 

 In this case, the white remnants do not form the regular pattern of chinensis. Larva black, with interrupted 

 yellow longitudinal lines and yellow segment-incisions; tubercles and setae minute. On Prunus mume. Pupa 

 in a slight cocoon. Throughout China, S. E. Siberia, Korea and Japan. 



10. Genus : JSTeolytJiria Alph. 



Face with appressed scales. Palpus very short. Antenna in ^ with fascicles of cilia. Hindtibia in 

 (J dilated. Wings thinly scaled. Fovea wanting. Forewing with distal margin not very oblique; 1st and 2nd 

 subcostal? coincident, anastomosing with costal and usually anastomosing or connected with 3rd — 5th sub- 

 costal. Hindwing with costal margin relatively long. 



A. small genus, apparently confined to W. China and Tibet. 



abmxaria. N. abraxaria Alph. (17 a). Very similar to djrouchiaria, the black less deep, the curved orange post- 



median band obsolete, hindwing unmarked except for the discal dot and marginal spots. The name-typical 

 form, from Szechuan, has the white distal band of the forewing rather broad, the band which precedes 



eonfinaria. [% not widening posteriorly, the white streak from base behind the median vein consequently longer. — con- 

 finaria Leech (14 h) has the distal white band quite narrow, sometimes interrupted about the radials, the dark 

 band which precedes it gradually widening posteriorly. Che-tou and Ta-chien-lu; also occurs with the type 

 between Tcha-tji-kow and Tchangla. July — August.
