where it is inwardly bounded by a fine black line and then by a line 

 of turquoise-blue ; a fine anteciliary white line, obsolete towards the 

 apex. Thorax above anteriorly clothed with hairs, which are ferru- 

 ginous in some lights, posteriorly with green hairs ; abdomen black 

 above, pale fuscous below. 



This species belongs to the group whioh contains Thccla \Z&phyru&\ 

 tsanghie, Oberthur, and T. desgodinsi, Oberthiir,* from Thibet, but 

 appears to be quite distinct from either. It differs from the former 

 in being larger ; it has no brilliant blue spots on the margin of the 

 hindwing on the upperside on either side of the tail, and the colour 

 of the underside is black, not brown. From the latter (of which the 

 female only is known) it also differs in the ground-colour of the 

 underside, and in the discal white lines being straight, instead of 

 outwardly convex as in T. desgodinsi, and in the presence of the bar 

 in the costal interspace on the hindwing, T. diamantina, Oberthur, f 

 which is also of this group, appears to have the green colour 

 on the upperside of the male less powdery, and reaches much 

 nearer to the outer margin. It was described from the Isle 

 of Askold. From the description alone Z. 50a appears to come 

 very near to "Dipsas "Japonica, Murray, J but that species is said to 

 have no disco-cellular markings on the underside, and has also a 

 third black spot with whitish scales in the middle between the two 

 large ones on either side of it on the underside of the hindwing near 

 the anal angle not found in my species. To judge of it also 

 from the late Mr. H. Pryer's figures in his " Rhopalocera Nihonica" 

 the male has the green coloration of the upperside much more 

 extensive than in Z. zoa. 



A single specimen has been obtained by Mr. A. V. Knyvett on 

 Tiger's Hill, above Darjiling at 8,000 feet elevation, on 26th June, 

 1888.
