AMATHUSINZ. 175 
lower median veinlets. Body beneath, legs and palpi pale brown; forelegs beneath 
whitish ; side of palpi white streaked. 
Female. Upperside ochreous-brown basally, dusky-brown anteriorly. Forewing 
crossed by an oblique subapical broad pale yellow band, which is entire from the 
costa to the middle median veinlet, below which is a small triangular spot followed 
by two pale ochreous lower submarginal spots and lower marginal line; a small pale 
yellow spot also before the apex. Hindwing broadly lunularly-bordered with pale 
ochreous or cinnamon-brown. Underside similarly coloured to male. 
Expanse, ¢ 3,8, to 4, 2 4,°, inches. 
Hasrrat.—Upper Tenasserim. 
The male of Z. Masoni is distinguishable, from the same sex of the allied Ma- 
layan Z. Amethystus, on the upperside of the forewing, in the oblique blue band being 
comparatively narrower and more excurved in its course ; and on the hindwing in 
the posterior blue band extending fully up to the upper median veinlet and more 
narrowly along the margin to the apex. On the underside the ground-colour is 
darker, the discal transverse fascia and the short basal fasciz also darker ; the two 
ocelli on the hindwing being about half the size. he female of Z. Masoni differs 
from the same sex of Z. Amethystus in its paler ochreous-brown colour, and on the 
forewing in the greater width of the subapical pale yellow band, this band being 
entire and terminates at the middle median veinlet, below which are two small yellow 
spots, but no inner discal third spot. The hindwing is broadly bordered with pale 
ochreous or cinnamon-brown. 
Distripution.—The type specimen—a female—was taken by Mr. Ossian Limborg 
at Meetan, 3000 feet altitude, Upper Tenasserim, in April. A male was also taken 
by Capt. C. T. Bingham in the Lower Thoungyeen forests, Upper Tenasserim, at the 
same season. Mr. W. Doherty obtained it in Hast Pegu, at 4000 to 5000 feet, in 
March, April and May. 
Of the illustrations of this species on our Plate 144, fig. 1, la is that of a male 
in Mr. Philip Crowley’s collection, and fig. 1b is that of a female, from Hast Pegu, 
taken by Mr. W. Doherty, and now in the possession of Mr. F. Godman.
