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, (S S^-q to 4, ? 4^^ inches. 



Habitat. — 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 fasciae also darker ; the two 

 ocelli on the hindwing being about half the size. The 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. 



DiSTEiBUTioN. — 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. 0. T. Bingham in the Lower Thoungyeen forests. Upper Tenasserim, at the 

 same season. Mr. W. Doherty obtained it in Bast 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. lb is that of a female, from East Pegu, 

 taken by Mr. W. Doherty, and now in the possession of Mr. F. Grodman.
