B. At least the forewing beneath before the middle with a dark transverse line from the costal margin right 
across the discal cell to the rise of vein 2. The discal line of the forewing extends somewhat behind the middle 
of the wing. Hindwing beneath without a submarginal line, at the anal angle in the areas lb, 1 c 
and 2 broadly covered with yellow.

lines at the proximal margin. 0 . amasa.

differs from the $ of homeyeri by the anal area of the hindwing being broadly covered with orange-yellow.

7. Genus: Hypolycaeiia Fldr. 
Both wings have beneath in the marginal half two transverse lines the proximal one of which (the discal 
band) is broader and extends in the middle or close behind the middle, whilst the other, finer one (the sub¬ 
marginal line) extends close to the margin. At the anal angle of the hindwing beneath there are in 1 b and 2 
two black spots more or less scaled metallic, usually proximally bordered by glaring colours. Forehead changing 
from black to orange-yellow with fine, white, raised lateral margins. 
The forewing is more triangular and shows a sharper apex than in Oxylides. 
The species may be divided into four groups easily discernible according to the following review. 
Review of the Groups of Species. 
A. Both wings beneath in the basal half as far as the discal band one-coloured white without markings (very 
rarely with a dot in area 7 of the hindwing). The discal band is brownish-yellow bordered with black; the 
submarginal line is blackish. Eyes hairy. 
a. The small tail at vein 1 b of the hindwing distinctly longer than the hindwing itself (from the base to 
the anal angle) and more than twice as long as the small tail at vein 2. — Zeltus de Nicev. 
First group. 
(k The small tail at vein 1 b of the hindwing not longer than the hindwing itself and not twice as long as 
the small tail at vein 2. Second group.
