274 LEPIDOPTERA INDICA. 



rest of the wing rick peacock-purple ; a quadrate spot beyond the end of the cell, and 

 an elongated one beyond and below it in the second median interspace, orange. Cilia 

 black. Hindwlng unmarked, the tail black, tipped with white. Cilia white, tipped 

 with black, except at the terminatiofi of the veins from the second median to the 

 second sub-costal nervule, where the cilia are entirely white. Underside, both wings 

 brownish-fuscous. Furewing, the dlscocellular nervules defined with a white line on 

 each side ; an obscure darker broad discal fascia from the costa to the first medial 

 nervule outwardly defined with a narrow white line, beyond which the wing is 

 sprinkled with pale violet scales ; another dark fascia from near the anal angle, 

 decreasing in width from the inner margin to the third medial nervule, where it 

 becomes obliterated, also outwardly defined with a whitish line. Rindwing sprinkled 

 almost throughout with pale violet scales ; a broad irregular wedge-shaped discal 

 fascia, free of violet sprinkling, broad on the costa, narrowing to a bluntly rounded 

 point above the anal angle, its margins defined with a fine violet-white line ; another 

 similar fascia beyond, inwardly defined with violet-white lunules ; two sub-basal ring 

 spots, one of which is within the discoidal cell, and a pair of lines on the abdominal 

 margin, all violet-white ; a sub-marginal oval black spot in the first median interspace, 

 surrounded by a deep orange ring ; a deep orange patch at the anal angle extending a 

 short distance up the abdominal margin ; a fine anteciliary dark line inwardly defined 

 by a white line. 



Zejyhyrus pavo is nearly allied to the Z. katura of Hewitson, that species being 

 probably the female of Z. ataxus, Doubleday and Hewitson, but differs on the upper- 

 side of the forewing in having the basal area of a richer shade of purple, of greater 

 extent, and not divided by the black veins ; on the underside the silvery bands in 

 Z. katura are replaced in Z. pa^-o by violet irrorations ; the two species also diff"er in 

 other minor particulars. 



The type specimen is unique, and is deposited in Mr. A. V. Knyvett's collection, 

 by whose native collectors it was obtained near Buxa in Bhutan. 



Mr. W. Doherty has recently taken a male specimen of this species near 

 Margherita in Upper Assam, at 400 feet elevation only. It agrees closely with the 

 type, but is a little larger. The specimen I described may also be a male ; it is very 

 singular, however, that the male of Z. pavo should put on the pattern of markings and 

 coloration of females of several Indian species, though it is probably to be accounted for 

 by the fact that they represent the primordial coloration of the group, and that the 

 green colour of the upperside of the males of several species has been but lately 

 acquired by that sex. (de Niceville.) 



Female. Upperside brown with a faint blue gloss. Forewing with the apical and 

 outer marginal borders rather broader than in the male. Ilindwing without markings. 

 Underside paler than in the male. Forewing with the discal band much broader,
