" Head large. Eijes smooth, the space between them prominent, thickly clothed alternately with 
black and white hair. Palpi smooth, very erect, long ; the second joint compressed, rising 
above the head ; the terminal joint of the male as long as the second. Antenna of moderate 
length, with numerous short joints indicated by white on the underside. Bochj robust. 
•■' Anterior wing triangular ; costal margin nearly straight ; outer margin slightly curved out- 
wards, shorter than the other margins ; inner margin slightly projecting near the base, where 
it is clothed with a tuft of hair on its underside. Costal nervure extending to the middle of 
the margin ; subcostal nervure with three branches, two before the end of the cell, the third 
at a distance from the apex ; the discoidal cell half the length of the wing, closed by two 
discocellular nervules in a straight line ; the second three times as long as the first, joining 
the third branch of the median nervure a little beyond its base ; the uj)per discoidal nervure 
leaves the subcostal before the end of the cell. 
" PosiEEioE WINS with two slender tails ; the abdominal fold and anal angle clothed thickly with 
long hair ; the costal nervure continued to the apex of the wing ; the subcostal branched 
before the end of the cell ; the cell short, closed obliquely by nervules of equal length joining 
the third branch of the median nervule a little beyond its base." (Hewitson, I. c.)

"Male. Brilliant ultramarine blue. Anterior wing with more than the outer half dark brown, the 
tuft of hair at the meeting of the wings black. Posterior wing with the costal and outer 
margins brown. Underside grey, paler towards the outer margins. Both wings crossed 
beyond the middle by a linear band of brown ; the outer margin rufous. Posterior wing 
with the two black spots near the anal angle crowned with orange. Expanse Ij'j inch."' 
{Hcwitsoo, I. c.) 
" Female. Both wings black. Fore wing with the lower basal and discal areas pale blue, rather 
darker towards the base of the wing. Hind wing with the disc more or less pale blue ; some 
indistinct black submarginal spots ; anal lobe bright ochreous, as in the male. Cilia whitish 
throughout. Underside : both wings as in the male." (de Niceville, I. c.) 
I. contractus, Leech. — Male. Black, ornamented with bright dark blue, which on the primaries 
forms a patch extending from the base to the middle of the disc between the median and 
submedian nerves, slightly encroaching beyond each boundary. On the secondaries the blue 
forms a broad oblique abbreviated band, its anterior limit being the second subcostal nervule, 
and its posterior the first median, but there is a small triangular mark beyond this latter 
boundary, extending to the orange spot at anal angle ; there are some black spots towards 
the outer edge of the blue baud ; the abdominal margin is paler, becoming whitish at the 
base. There are two tails of equal length, both black with white tips. Under surface of
