One of these is the largest and most striking species of 
Calisto yet to be described. When the island is thoroughly 
explored, it will probably be found that the various moun- 
tain ranges are inhabited by distinct local populations of 
many of these Calisto species, and there is evidence of such 
geographical variation in some of the series in the collec- 
tion of the M. C. Z. ; there seems, however, to be no point 
in giving names to such subspecific populations at the 
present time. 
Calisto areas sp. nov. 
$ 2. Sexes similar. Upper side: forewing: dark 
fuscous with a row of large more or less confluent sub- 
marginal fulvous spots extending from the inner margin 
to vein M 2 ; hindwing with the basal half fuscous, the distal 
half fulvous, except for a narrow, sharply defined, burnt 
orange submarginal line and a fuscous margin at the outer 
angle extending to vein M 2 . Under side: forewing: dark 
reddish brown from base to just beyond cell, except for a 
black area along the inner margin; postmedian area ful- 
vous, marked off by narrow brown lines ; margin somewhat 
darker ; ocellus in the fulvous area : black surrounded by a 
yellow ring; two bluish white central dots. Hindwing a 
rich brown, the basal half slightly yellowish, the distal half 
reddish; distinct antemedian, postmedian and submarginal 
dark lines ; two ocelli of about equal size, both marked with 
yellow rings, the center black enclosing small, central,, 
bluish-white dots ; one ocellus in the M x — M 2 area, the other 
in the Cu x — Cu 2 area; an isolated white dot in the M 2 — M 3 
area; Length of forewing, 24 — 27mm. 
$ . The androconia are limited to the Cu-Cu 2 and Cu- 
2A areas; they do not form a sharply defined patch. The 
genitalia of this species are quite distinctive: the uncus 
being asymmetrical, and the valves elongate, squared at 
the end.
