also has a very narrow outer black margin. The former may perhaps be known from the latter 
by the more profuse markings of the underside in both wings. The male, as in that sex of 
A. atosia, Hewitson, has a large round patch of differently-tinted scales on the upperside of the 
forewing on the disc seen only in certain lights, 
Lastly will be found below" a description of 4. 4ursi, Distant, also from Malacca. The 
male is dark violaceous-blue on the upperside, the markings of the underside darker brown 
than the ground-colour, outlined with greyish, the discal band very short, ending posteriorly 
at the second median nervule, where it is strongly bent inwards. In 4. andimuta, Felder, this 
band is continued in a gentle curve to the submedian nervure, as shown in Mr. Distant’s figure 
of the species.

Hasirar: Myitta, Tenasserim valley, Burma, 
EXPANSE : d@, 1°8 inches. 
DESCRIPTION : “ MALE UPPERSIDE, doth wings rich uniform purple-blue over fully half 
the forewing and two-thirds of the hindwing. /vrewing with the costal border and lower 
angle narrowly, and the apex widely black. AMindwing with the costa widely and the outer 
margin narrowly black, the blue extending beyond the submedian nervure. UNDERSIDE, doth 
wings dull fuscous-brown, the markings but slightly darker, bordered by lines a little paler ; 
only the basal spots on the hindwing annular, the others with straight borders. Forewing 
with three spots in the cell, and a broad uniform band, unbroken and but slightly curved, from 
the third subcostal to the first median nervule, the base of the first median interspace and the 
upper and basal part of the interno-median interspace dark, separated distinctly from an 
outer pale area in the interspace ;a submirzinal line of obscure darker spots bordered by 
aslightly paler line. Avindwing with the basal spots small and well-separated, a streak 
across the end of the cell extending to the submedian nervure, and a transverse discal band, 
dislocated outwardly below the second subcostal nervule, continuous in the next four inter- 
spaces ; submarginal markings as on the forewing ; a metallic green fascia from the first median 
nervule to the submedian nervure, anda touch of it on the spot in the first median interspace. 
The hindwing is distinctly undulate outwardly; it has no tail and but slight traces of a 
lobe.” 
‘**I know no species closely resembling it. It is a richly coloured butterfly above, but 
the underside is unusually dull-coloured.” (Doherty, |. c.) 
A very distinct species, which may be known from all the others of this group by the broad 
black margin to the forewing on the upperside, and the broad dark band below the discoidal cell 
on the underside exactly as in 4. counguva, Grose Smith. The type specimen is unique.
