several beyond these near the apex, and a large irregular band extending from 

 near the apex and along the dorsal margin, emitting three broad streaks, one of 

 which enters the apex, and the two others reach the dorsal margin ; beyond this 

 band, nearer the base, is a less distinct and somewhat quadrate spot on the dorsal 

 margin, and there are also two small and distinct discal blackish spots, one near 

 the base, the other in the middle ; the whole wing is rather thickly sprinkled with 

 pearly drops, being in reality portions of the membrane which have not acquired 

 the yellow ground tint ; in the fuscons band these dots are more distinct, and 

 several of them are there much larger, forming large spots ; neuration moderately 

 open, the veins and veinlets yellow, with minute black points, from each of which 

 springs a short blackish hair : posterior wings hyaline, all the basal veins and 

 veinlets, and also the gradate veinlets, black and suffused with blackish ; the 

 longitudinal veins between, and on each side of, the gradate series, whitish, with 

 blackish points. 



There is a specimen of this beautiful species in the British Museum, 

 and I have a long series before me, which I owe to the liberality of 

 Captain Lang, by whom they were collected at Masuri, in June.

Whitish, with a pale yellow tinge. Crown of head much inflated, with 

 irregular blackish markings ; front with blackish dots, and blackish lines at base of 

 antennal sockets : palpi annulated with piceous : antennae yellowish white, the 

 two basal joints (and sometimes also the third) pitchy black. Prothorax rather 

 short, slightly broader posteriorly ; above, with interrupted longitudinal blackish 

 lines, and clothed with sparse but long yellowish hairs : mesothorax large, much 

 inflated. Legs pale whitish yellow, and clothed with long concolorous hairs ; the 

 apex of the tarsi testaceous, claws testaceous, curved, internally at about the 

 middle with two or three small and indistinct teeth. 



Wings broad, sub-acute at the apex, whitish-hyaline with whitish veins and 

 veinlets ; the costal margin and neuration longly ciliated : anterior wings with the 

 costal area very broad at the base, rather abruptly dilated (almost as in Ancylopterya

 the somewhat yellowish pterostigmatical region, the inner of which is the larger,
