Described from a single example for which I am indebted to Major 

 F. B. Longe, R. E., captured in the Kokang State, 5,500 feet, North 

 Shan States, on the Chinese frontier east of Bhamo, on 6th April, 1895. 



Subfamily NrMPHALiNiE. 



4. Cynthia cyonia, n. sp., Plate III, Figs. 19, c? ; 20, $ . 



Habitat : Ke Islands. 



Expanse : c?, 3*4; $ , 3*6 to 3-8 inches. 



Description: Male. Upperside, forewing differs from 0. orahilia, 

 Kheil,* from Nias Island, in the discal black line just beyond the discoidal 

 cell being straighter and thereby more continuous ; beyond this there 

 is a series of six black lunules crossing the middle of the disc, the 

 anteriormost one developed into a rounded spot, the posteriormost one 

 W-shaped ; beyond this again there are five small round black spots 

 placed between the veins (one being wanting in the lower discoidal 

 interspace), in 0. orahilia there are never more than four, and usually 

 three or two ; the interior of the two submarginal black lines is more 

 lunulated in G. cycnia ; and the anteciliary black thread is narrower. 

 Hindwing has the interior submarginal black line also more lunulated, 

 and the anteciliary black thread also inconspicuous, in G. orahilia it is 

 very prominent. Underside, both wings of a rich red-orange colour 

 instead of ochreous ; the discal black line almost perfectly straight 

 instead of being irregular ; the interior submarginal line more irregular ; 

 the markings otherwise similar. In outline 0. cycnia has the forewing 

 more produced at the apex, the outer margin consequently more deeply 

 excavated ; and the tail of the hindwing is rather longer. Female. 

 Upperside, both wings dark ochreous, sprinkled throughout (except a 

 broad discal paler ochreous area) with fuscous, in the male the ground- 

 colour is rich dark red-orange ; the markings almost precisely similar 

 to those of the male, differing only in the forewing in the discal black 

 line just beyond the discoidal cell being broader and lunulated instead 

 of being almost straight; and the five discal round black spots are 

 considerably larger. Underside, both wings differ from the male in being 

 ochreous instead of red-orange ; the markings similar. The female 

 differs markedly from the same sex of 0. orahilia as figured by Herr 

 Gustav Weymer in having the disctl area of both sides of both 

 wings rich ochreous instead of pure white ; the markings, however, 

 are very similar. 



As far as I am aware this is the only species of Gynthia which has
