LYCAENID. ARHOPALA. 251 
*“Nearest to S. size/a, from which it differs in the forewing being shorter and truncated 
instead of produced at the apex, the marginal black line on the upperside only a quarter as broad, 
and the coloration of both wings of a deeper shade of purple. Obtained in the Teesta Valley, 
Sikkim, by Mr. Otto Moller, in whose collection the type specimen is deposited.” (de Nicéville, 
Ice) 
Mr. Otto Moller possesses eleven males of this species, some of which were taken in 
November. The much deeper purple coloration and the narrower outer black border of the 
upperside of both wings will at once distinguish it from 4. sizgla, mihi. I am unable to say 
how the female of 4. /cesta can be distinguished from that of A. singla. Its range is wider 
than I was aware of when I described it from Sikkim specimens, the Rev. Walter A, 
Hamilton having sent me both sexes taken near Shillong, probably in the low hot Sylhet Valley, 
and I possess a male taken by Major C. T. Bingham at Shwayghan in Upper Tenasserim. 
The figure shows both sides of a male specimen from Sikkim in the collection of Mr. Otto 
Moller. 
I give below as a foot-note* a description of 4. agrata, mihi, which occurs at Singapore, 
On the upperside it resembles 4. ¢ees¢a in having the ground of the same very deep shade of 
purple,

EXPANSE: @, 9, 1°50 to 1°75 inches. 
DESCRIPTION : “ MALE. UPPERSIDE, doth wings purple. Forewing angulated exteriorly, 
with broadish brown exterior margin commencing from middle of anterior margin. Aindwing 
rounded, one tail, with broad brown margins. UNDERSIDE greyish-brown, slightly rufescent 
on the forewing, an undulating broad band of rufescent-brown crosses both wings, another 
inwardly on the hindwing half across the wing, then two or three spots ; near exterior margin 
of both wings is an indistinct angulated line. FEMALE. UPPERSIDE, forewing with the dis- 
coidal cell and posterior base purple, the disc being somewhat lighter and pinky, the rest of 
the wing brown. Aindwing with the middle purple, the rest brown.” UNDERSIDE, both wings 
as in the male. (4Zoore, |. c. in Cat. Lep. Mus. E. I. C.) 
Mr. Doherty remarks (1. c.) that though this species “ belongs to a tropical group, I 
found it flying in great numbers on the mountain near Ramgarh, 7,500 feet, in December, 
when the ground was powdered with snow. The males and females of A. rama are very 
much alike. A. dvdone@a seems to be a distinct species.” 
Mr. Hewitson (1. c.) says that “ This species may be known by the silky gloss of the under- 
side. It is the same in both sexes.” 
«“ The males are larger than the females, and have a narrower black border to the forewing 
on the upperside. P. rama and P. dodonea are both common species” at Murree. (Builer, 1. c.) 
A. rama is one of the commonest and most widely-spread species of the genus. In the 
* Arhopala agrata,n.sp. (FRONTISPIECE, Fig. 137, ale). Hapnirat: Singapore. Expanse: Male, 
r’8inches. Description: Mate. Upprrsive, doth wings extremely deep purple, almost black, of the exact 
shade of A. ¢eesta, mihi; cé/za black. Hindwing with the abdominal margin pale. UNDERSIDE, doth wings 
dull brown, all the markings very indistinct, but very slightly darker than the ground, outlined obscurely with 
grey. Forewing with the usual three spots in the cell, two below it divided by the first’ median nervule, the 
discal band composed of five spots, the two lowest shifted inwards below the third median nervule. Hindwing 
with the usual bands and spots ; the black anal lobe very small, with some metallic blue irrorations beyond ; 
tail probably of the usual Jength, but mutilated in my specimens, a portion of the base alone remaining. 
Described from two specimens communicated to me by Mr. W. Davison, Curator of the Raffles 
Museum, Singapore. 4. agrata is not closely allied to any species as faraslam aware. 
The figure shews both sides of the type male in the collection of the Ra‘les Museum, Singapore.
