The male of A. anthelus isthe most magnificent species of the genus occurring within 
Indian limits, the blue of the upperside almost rivalling some of the South American 
Morphos. Itisavery rare species; I have seen but a single specimen taken by Major 
Cc. T. Bingham in April in the Upper Thoungyeen Forests in Upper Tenasserim, and a 
pair from Mergui obtained during the cold weather by Mr. W. Doherty.

DESCRIPTION: * MALE. UPPERSIDE, doh wings brilliant silvery blue, tinted with lilac 
near the margins; the margins with a very narrow border of black. UNDERSIDE, Goth wings 
with the basal spots large, the usual transverse band represented by a chain of spots, which 
commence at the middle of the costal margin and curve round towards the middle of the outer 
margin, five in number, where they are succeeded by three other spots at a greater distance 
from the margin. isdwing, the anal angle has three black spots irrorated with silvery-blue.”

Mr. Doherty obtained a single male only of this most beautiful species. Mr. Hewitson 
did not know the locality of his type male specimen, the female which he subsequently 
described from Sumatra as A. anarte is quite a different species, and has been named A. agnis by 
Dr. Felder. Hewitson’s figure of the male gives the blue coloration of the upperside of too 
light a shade ; the disc of both wings is very brilliant light blue, gradually shading off into the 
darker purple outer margin of both wings and costa of the forewing. The spots of the underside 
are larger than in any species occurring in the Indian region, of a shade of brown a little darker 
than the ground-colour, outwardly prominently defined with whitish. In the forewing there is 
a large spot at the base of the cell, a still larger transverse one at the middle of the cell, with 
a spot above it reaching the costal nervure, slightly divided by the first subcostal nervule ; a 
very large quadrate spot at the end of the cell, its outer edge twice indented where it is crossed 
by the discoidal nervules, with a small elongated spot above it ; a narrow elongated spot below 
the cell at the base of the second median interspace, another elongated much larger spot at the 
base of the first nvedian interspace, a figure-of-eight spot just within the base of the first median 
nervule, with a small round spot below it touching the submedian nervure ; lastly an oval spot 
near the base of the submedian interspace ; a much curved discal series of seven spots, of 
which the five wpper ones are oval and gradually increase in size to the fifth, the sixth and 
seventh are alittle out of Jine and somewhat kidney-shaped ;a submarginal regular series of 
inconspicuous elongated spots. In the hindwing the spots are arranged almost exactly as in 
A. agnis, Felder, but are a little larger. Both wings are distinctly glossed with purple. 
The single male obtained during the cold season of 1888-89 in the Tenasserim Valley by 
Mr. Doherty is the only specimen I have seen of this species,

* Mr. Moore described also a Narathura subfasciata (p. 267), which fortunately is a synonym of another 
species, otherwise the present species would have to be renamed, as lam unable to separate the two genera 
Narathura and Nilasera. The system I have adopted, as far as possible, in naming new species never to use a 
specific name which has been used before for Butterilies, appears to me to have several advantages.
