186 LYC/ENID. TARUCUS. 
DEscrIPTION ; “FEMALE. UPPeRSIDE, doth wings pale blue, with broad costal and 
outer black borders, deepest at the apex [of the forewing]. Hindwing with five marginal 
largish black spots surrounded by yellowish commencing near the anal angle, one in each 
interspace, with whitish streaks above each spot. UNDERSIDE, doth wings pale greyish, 
markings greyish-brown surrounded by white, a streak at the end of each cell, a whorl of discal 
square spots, a row of marginal and submarginal square spots, the submarginal spots having 4 
white band internally. [/zzdwzng with] a subbasal centre spot and three others below it in a 
line, and two black spots on an orange ground near the anal angle.” 
“This is closely allied to C. faxdava, Horsfield, and may probably be only a local form 
of that species.’’ (Szezzhoe, 1. c.) 
In the above description Colonel Swinhoe does not say how many specimens he possesses 
of this ‘‘new species, ” he does not figure it, and the male is undescribed. Nor does he say 
how it differs from C. ardava, but from the description the five black marginal spots surround- 
ed by yellowish on the upperside of the hindwing seem to be distinctive. I do not quite fol- 
low the “‘ subbasal centre spot and three others below it ina line” on the underside of the 
hindwing. In C. fandava there is a prominent black spot near the middle of the costa, and four 
subbasal spots arranged nearly in a straight line across the wing, the uppermost one close to the 
costa, the lowest on the abdominal margin, the two in the middle of the wing near together.

“‘ FOREWING, triangular; costa very slightly arched at base, afex slightly acute, exterior 
margin oblique and slightly convex, fosterior margin straight ; costal nerviere short, not extend- 
ing to half length of the margin ; first subcostal nervule short, emitted at one-half before 
the end of the discoidal cell, anastomosed to the costal nervure near its end ; second subcostal 
at one-third, and ¢hzvd subcostal at one-sixth before the end of the cell, fowth subcostal at 
one-half from third and terminating at the apex, //%/ subcostal [upper discoidal] from the end of

cell, first median at more than half before the end ; swdmedian nervure straight. HINDWING,

phrastus, Fabricius.” (Moore, 1. ¢) 
In the forewing the costal nervure is short, not reaching opposite to the apex of the discoidal 
cell ; the first subcostal nervule is suddenly bent upwards towards the costal nervure soon after 
its origin, and in the males touches the costal nervure (does not anastomose with it as 
Mr. Moore says), in the females there is a small portion of wing-membrane between these two 
veins ; the second subcostal has its origin slightly nearer to the base of the first than to the 
base of the upper discoidal ; the third subcostal has its origin rather nearer to the base of 
the upper discoidal than to the apex of the wing; in 7: ¢heophrastus the middle and lower 
disco-cellular nervules are in a straight line, upright, and of nearly equal length; in 
ZT. plinius the middle disco-cellular is slightly outwardly oblique, the lower upright. In the 
hindwing Mr. Moore says the first subcostal nervule is emitted at one-half before the end of the 
cell, in 7. ¢heophrastus it is given off at hardly one-third, and in 7. Alinius at about one-fourth 
before the end; in 7. ¢heophrastus the disco-cellular nervules taken together are nearly 
upright, the upper slightly outwardly, the lower slightly inwardly, oblique ; in Z. Alinius
