LEPIDOPTERA INDIGA. 
SIKTCHTJLA VAIVARTA. 
Wet-Season Brood. 
Imago. —Both sexes differ from the wet-season form of S. Sidonis in having the 
forewing less triangular, the apex being more obtusely rounded, and the exterior 
margin less oblique; the hindwing also is comparatively more convex externally and 
less scalloped; cilia dusky, alternated with cinereous-white. Upperside of the same 
colour as in 8. Sidonis, except that the dusky lunular submarginal border is absent; 
the forewing not possessing a visible dusky oblique transverse discal line which is 
apparent in 8. Sidonis, and the apical costal pale spot only is very indistinctly present. 
Underside similar to the wet-season form of S. Sidonis, except that, on the for awing, 
the bar across the cell is more or less obsolescent, the transverse discal darker brown 
line is more convex and comparatively less oblique and its costal end is less exter¬ 
nally pale bordered ; the outer costal spot above the small ocelli is also less defined. 
Hindwing similar to S. Sidonis, the glossy lilacine-blue lines being less prominent. 
Expanse, <J ? 2 to 2f inches.

Imago. —Shape of wings very much as in S. Sidonis, except that on the hind¬ 
wing the angle at end of upper median branch is obsolescent, and those at the ends 
of the lower medians are more produced. Male. Upperside glossy olivescent 
ochreous-brown; cilia alternated with cinereous-white. Forewing with two dull 
ochreous costal spots, and a faint trace of a pale oblique transverse discal band from 
the inner spot. Hindwing with five distinct black submarginal spots. Underside 
somewhat paler olivescent-brown than the upperside. Forewing with a pale bar 
across the cell, a distinct transverse discal line with yellowish anterior-bordering 
fascia; a pale lilacine-white costal spot at the furcation of last subcostals, 
below which are four very indistinct brown ocellate-spots with minute lilacine 
pupils. Hindwing with three irregular subbasal, and a discal lilacine line, the latter 
exteriorly bordered by darker brown; six submarginal ocelli, the last duplex, the 
second, third, and fourth being less prominent than the others and with a small 
lilacine pupil; submarginal lilacine lunular line indistinct anteriorly. Female. 
Upperside somewhat paler than the male. Forewing with the inner costal spot and 
discal pale fascia much moi’d distinct; the subapical spot and four lower pale minute 
ocelli also visible. Hindwing with the submarginal black spots slightly pale ringed. 
Underside as in the male, except that on the forewing the oblique discal fascia is 
broader, and the subapical spot and four lower small ocellate spots more distinct; 
and on the hindwing the ocelli are somewhat larger. 
Expanse, c? 2f, ? 2f inches.
