LYCAINID. EUASPA, 309 
with females of Z, dirupa, Moore, differing in the colour of the ground of the underside, which 
is white, and in the lower portion of the submarginal band of the forewing being composed of 
two large quadrate black spots, the lower the larger. The sexes are alike, I can only discrimi- 
nate between them by examining the primary sexual organs. 
875. Zephyrus pavo, de N. 
Z. pavo, de Nicéville, Proc. Zool. Soe, Lond., 1887, p. 460, pl. xl, fig. 11, female. 
Hasitat: Bhutan ; Margherita, Upper Assam. 
EXPANSE: 2, 1°35 inches. 
DESCRIPTION: ‘* FEMALE. UPPERSIDE, both wings black. Forewing with the costa 
somewhat widely, the apical third of the wing, and the outer margin at the anai 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. C7/éa black. 
Hindwing unmarked, the ¢az/ black tipped with white. Cz/za 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, doth wings brownish-fuscous. Forewing with 
the disco-cellular nervules defined with a white line on each side ; an obscure darker broad discal 
fascia from the costa to the first median nervule outwardly defined with a narrow white line, 
beyond which the wingissprinkled 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 
obliterated, also outwardly defined with a whitish line. Azadwing sprinkled almost through- 
out with pale violet scales ; a broad irregularly 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 within the 
discoidal cell, anda pair of lines on the abdominal margin, all violet-white ; a submarginal 
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. katura of Hewitson ;* that species being 
probably the female of Z. ataxus, Doubleday and Hewitson, but differs on the upperside 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. favo by violet irrorations ; the two species 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.” (de Wicéville, 1. c.) 
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 isa little 
larger. The specimenI described may also be a male; it is very singular however, that 
the male of Z. avo should put on the pattern of markings and coloration of the 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.

“FOREWING, short, broad ; costa arched from the base ; exlerior margin erect, convex ; 
posterior margin long, straight ; first subcostal nervule emitted at two-sixths, and second at one-

the end of the cell ; dzsco-cel/uwlar nervule very slender, erect, waved ; disco¢dal nervule from its 
middle ; dscoidal cell broad, extending to half length of the wing ; second median nervule from 
near the end of the cell, 7st median at one-third before the end ; swbmedian nervure straight.
