the cell and touching the costa, five arranged in a strongly curved line 
beyond the middle of the wing, and seven along the apex and outer margin. 
Hind-wing entirely orange-tawny, except two dark brown spots, one at 
the apex and one below the lower disco-cellular nervule ; there is also 
a sub-costal dark brown streak. Beneath : same as above, except that 
there is a row of small white spots close to the hind- wing outer margin, 
becoming obsolete towards the anal angle. Antennae yellow, base black, 
collar and wing lappets orange-tawny.

$ . Exp. 3" 6'". In shape of wings precisely similar to T. Sar- 
monia (Cram.), to which species it is most closely allied. The fore- 
wings, however, are wholly of a dark brown colour, with yellow spots, 
and the hind-wings have not a black discoidal stripe. The yellow spots 
of the fore-wings are 14 in number, one of them, irregular in shape, 
occupies the end of the cell, and is accompanied by a smaller spot on 
the costal side of the sub-costal nervure ; four are arranged in an 
oblique row near the apex, as in T. Harmonia ; the rest are placed very 
irregularly between the sub-costal nervure and the hind angle. The 
hind-wings are of a reddish-fulvous, with a costal stripe and hind 
borders black ; the only trace of a discoidal stripe consists in two small 
spots between the branches of the median nervure and between the last 
branch and the lower radial nervure. The antennae are fulvous, with 
the base black .- the collar is very dark chesnut-red, and the wing-lappets 
are black ; this latter character distinguishes the species thoroughly 
from all the local forms of T. Harmonia.

Allied to H. hecalesia Hewits. (Exot. Butt. Hel. fig. 6), and 
closely resembling it in colours. Wings more elongated and narrower, 
the fore-wing costa being strongly arched and the apex broadly obtuse, 
with the outer margin slightly incurved, less scalloped, and destitute 
(as well as the hind-wings) of white edging in the sinuses. Ground 
colour of the fore-wing above deep blackish-brown, as in H. hecalesia, 
but having a broad central dark orange-tawny stripe, extending from 
the base to near the middle, and the yellow spots, of which there are 
two belts between the middle and the apex, obliquely elongated. Hind- 
wing dark orange-tawny, with a dark brown outer border of nearly 
uniform width, and marked with five moderately small and squarish
