shining bare patch denuded of scales in the centre, on which lies a thick tuft of long brown hairs ; 

 and above the subcostal nervure before the base of its first branch is a similar but smaller tuft 

 on a black patch in the centre of a similar patch denuded of scales. 



Only a single species is certainly known to occur within our limits, where it is found in 

 Upper Tenasserim. Another species is recorded from India, but the authority is somewhat 

 doubtful. All the species are rare, and a single male of Z. fnasoiii'm. Major Marsliall's collection 

 is the only specimen of the genus in the collections in this country so far as we know. 



Ecy to the Indian Species of Zeuzidia. 



A. Males. Uppet side dark brown, forewing crossed by a broad band of purplish-blue or blue ; hindwing, 

 with a similar band on the outer margin.

Habitat : Upper Tenasserim. 

 Expanse : <J, 4'i ; ? , 4"5 inches. 



Description : Male : Uppekside velvety blackish-brown, paler at the margins. Forewing 

 crossed by a purplish-blue subapical decreasing band extending from the costa just beyond the cell 

 to the hinder angle. Hindwing with a broad purplish-blue patch from the anal margin extend- 

 ing on the outer border to the fold below the discoidal nervule. Underside brown, with 

 violet-whitish markings ; the basal half of both wings darker, and defined by a dark brown 

 median line from the middle of the costa of the forewing to the anal angle of the hindwing. 

 Foreiuing with three whitish bands in the cell, and one just beyond it, the costal half beyond the 

 median line being clouded with whitish to the apex. Hindwing with three nebulous whitish 

 bands on the basal half, that nearest the base the broadest and most distinct ; the median line 

 edged exteriorly with whitish irrorations ; two moderate-sized ocelli, one between the subcostal 

 nervules, brown, with diffused yellowish pupil, narrow yellowish iris, and outer dark brown 

 line ; the other on the lowest median interspace yellowish with eccentric brown pupil and 

 dark outer line. Described from the male in Major Marshall's collection. "Female 

 dilTers from Z. amethystus, female, in the paler colour of the wings, and in the greater 

 breadth of the yellow oblique band, the band entire, and terminating at the middle median 

 nervule, below which are two similarly-coloured spots ; a small pale patch before the apex 

 of the wing. Hindwing ■p^tXe cinnamon-brown broadly along outer border." (Moore, 1. c.) 



Closely allied to Z. amethystus* from the Malay Peninsula, Sumatra and Borneo. The 

 female of Z. masoni wa.5 taken by Limborg in Upper Tenasserim at Meetan 3,000 feet altitude 

 in April ; the male was taken by Captain C. T. Bingham in the Lower Thoungyeen forests in 

 the same district at the same season. It is a very rare insect.
