united and compact, the first is small, close to the costa, the second broadest ; the fifth and sixth 
spots dislocated inwardly, compactly united ; a submarginal series of obscure dark spots, 
bordered within and without by obscure paler touches. Aindwing with the basal spots of 
moderate size, annular ; a transverse discal series of nine spots in a tolerably regular semicircle, 
all somewhat annular, none approaching the terminal cell-streak ; a submarginal series of 
obscure dark cordate spots bordered with paler; a slight metallic green streak in the first 
median interspace, and a similar band from the first median nervule to the submedian nervure, 
both bordered with black; the anal lobe is small, black; there are slight projections at the 
ends of the first median nervule and submedian nervure, but no distinct tails, the outer margin 
is regularly rounded without undulations,” 
“In the colour of the upperside this butterfly perhaps resembles A. /ycenaria, Felder, 
a smalier species and tailed. It is very near 4. agelastus, Hewitson, but that species is 
smaller, more violet apically, and not distinctly metallic above; on the underside the 
transverse bands are more regular, the costal spot of the forewing is absent, and the general 
colour duller and more fuscous, less rufous.” (Doherty, 1. c.) 
A, pastorella has been described from a single example. It is a little larger than A. agelas- 
tus, the upperside is a little more brilliant, on the underside the coloration is rather less rufous, 
the discal band of the forewing is more regular ; in 4. agelastus the spot in the lower discoidal 
interspace is usually much out of line, being projected outwards towards the margin ; in some 
specimens, however, it is quite in line with the rest ; the costal spot spoken of by Mr. Doherty 
is sometimes absent in A, agelastus. The last-named species often has in the male traces of a 
*‘male-mark ” on the disc of the forewing on the upperside, a character wanting in 
A, pastorella. The species is really almost indistinguishable, as far as I can tell from 
the figure, from 4. moolaiana, Moore, but the discal band of the forewing on the underside 
is differently formed, being of nearly equal breadth, curved out and in, in 4. moolaiana ; while in 
A. pastorella the uppermost spot is very small, the second very large, the third and fourth 
decreasingly smaller, the fifth spot shifted inwardly towards the base of the wing, and the 
sixth in a line with the fourth,

DESCRIPTION : ‘* MALE. UPPERSIDE, doth wings with the margins broad, dark brown. 
Forewing violet-blue. Hindwing brilliant morpho-blue. UNDERSIDE, forewing with the /7 st 
three spots of the transverse band Placed obliquely outwards, the other two spots a little within 
themand Placed transversely.” 
“This species may be readily distinguished from A. Avpomuta, Hewitson, by the broad 
margins, and by the different blue of the fore- and hindwings.” (ewvtsov, 1. c.) 
Mr. Butler, I think quite incorrectly, states that Hewitson erroneously determined the 
sex of the specimen he described, and redescribed the male as follows:—‘'* MALE. Up- 
PERSIDE, doth wings deep purple as in the forewing of the female, but without the black 
border,” (Butler, 1. c.) Mr. Butler’s specimen certainly appertains to a different species. 
Mr. Doherty has kindly lent me two males of this species taken at Mergui and in the 
Tenasserim valley in the cold season, and there is a single worn female in the Indian Museum, 
Calcutta, collected by Dr. J. Anderson on Kisseraing Island in the Mergui Archipelago on 28th 
December, 1881, which has been ideutified by Mr. Moore. ‘These are all the specimens I have 
seen of this species. The male is very easily recognised, owing to the difference in colour between
