LYCANID. ARHOPALA. 278 
Forewing pointed at the apex ; with two oval marks and an undulating line of a paler colour, 
Hindwing rounded ; without tails ; with a broad, uneven, and indistinctly-defined fascia of a 
creamy colour crossing from the anterior to the abdominal margin, also marked with several 
oval and undulating lines.” (A/oore, 1. c. in Cat. Lep. Mus. E. I. C.) 
‘*MALE. UPPERSIDE, oth wings bright blue, the margins with a _ border of brown. 
UNDERSIDE, 4o¢h wings ferruginous, clouded with purple. /orewing with the transverse band 
unusually wide, broadest in the middle, purple. AHindwing with the base and outer margin 
purple.” (Hewitson, 1. c., Cat. Lycenide B. M., p. 12). FEMALE, UPPERSIDE, both wings 
glossy bluish-purple, with broad outer black margins, the costa of the forewing more narrowly 
black. UNDERSIDE, doth wings as in the male. 
A rare species in Sikkim ; Mr. Otto Moller possesses specimens taken in July and December. 
Mr. Hamilton has obtained it in the Khasi Hills, Mr. H. M. Parish at Rungamutti in the 
Chittagong Hill Tracts in October, Dr. Anderson in the Mergui Archipelago in January and 
February, and Mr. Doherty at Merguiand Myitta, Tenasserim valley, during the cold weather. 
The broad pale yellow transverse band across the middle of the hindwing on the underside 
occupying half the surface renders this little species easily recognisable.

DESCRIPTION. “*MALE. UPPERSIDE, forewing bright cerulean blue over fully half of the 
surface, the apex widely, the costa and outer margin moderately, and the veins slenderly black. 
Hindwing with the cell and the extreme base of the first median interspace irrorated with blue 
scales. UNDERSIDE, doth wings light brown ; the markings violet-brown with violet-whitish 
irides, only the basal ones annular. Forewing with the costal and apical half of the wing, in- 
cluding the upper half of the cell glossed with pale violet ; three transverse spots in the cell, 
a double one in the basal part of the first median interspace, a very broad compact dark trans- 
verse discal band unbroken from the costa to the submedian nervure, the apex of the wing with 
a whitish patch ; margin distinctly undulated outwardly. Aindwing glossed with pale violet ; 
with basal annular spots, an irregular spot at the end of the cell, outwardly acuminate, and a 
very irregular transverse discal band, of which the first and second spots are compactly united 
with the terminal cell-spot, the other five small and separate, forming an irregular chain ; an 
outer discal pale fascia forming a large violet-whitish mass near the apex, the disc also clouded 
with whitish ; an obscure submarginal line of pale violet lunules, the marginal line dark ; no 
metallic subanal markings ; no tail, lobe, or undulations. 
“Two males, Myitta. I know no species closely resembling this. It may be allied to 
A. bazalus, Hewitson, but has no tail or lobe. The distribution of the blue coloration on the 
upperside is very unusual.” (Doherty, 1. c.)
