1887.] LITTLE-KNOWN BUTTERFLIES FROM INDIA. 461 



margin at the anal angle black, the rest of the wing rich 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. Hind wing unmarked, the tail tipped with white. 

 Cilia white, tipped with black, except at the termination of the 

 veins from the second median to the second subcostal nervule, where 

 the cilia are entirely white. Underside brownish fuscous. Fore 

 wing with the discocellular nervule defined with a white line on 

 each side, an obscure darker broad discal fascia outwardly defined 

 wich a narrow white line from the costa to the first median nervule, 

 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 median nervule, where it becomes obli- 

 terated, also outwardly defined with a whitish line. Hind wing 

 sprinkled almost throughout with pale violet scales ; a broad irre- 

 gularly 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 subbasal ring-spots, one of which is with the discoidal cell, and 

 a pair of lines on the abdominal margin, all violet-white ; an 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. 



Zephyrus pavo is nearly allied to the Z. katuru of Hewitson ^ 

 that species being probably the female of Z. ataxus, Doubleday and 

 Hewitson, but differs on the upperside of the fore wing 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. pavo by violet irrorations ; they also 

 differ 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. 



Rapala distorta, n. sp. (Plate XL. fig. 6, $ .) 



Hab. Sikkim. 



Expanse. 5 1'6 inch. 



Female. Upperside : both wings almost black, somewhat paler 

 on the hind wing. Fore wing with all but the costa widely, the 

 apex and outer margin still more widely (which are of the ground- 

 colour), rich bluish purple. Hind wing with a lengthened discal 

 patch of bluish purple, which occupies the lower half of the discoidal 

 cell and extends beyond it into the discoidal and median interspaces, 

 but does not nearly reach the outer margin. Tail dull ferruginous, 

 tipped with white. Underside : both wings dull ferruginous or 

 cinnamon-coloured, glossed with vinous. Fore wing with a narrow
