282 LYCENID#. MAHATHALA. 
HABITAT: Upper Tenasserim. 
EXPANSE: 6, 1°453 2, 1°50 inches. 
DESCRIPTION : ‘f MALE. UPPERSIDE, J0¢4 wings shining bluish-purple, with a very narrow 
outer black margin. Hindwing with some marginal narrow black streaks on either side of the 
tail divided from the cilia by a white thread ; ¢a#? black tipped with white. UNDERSIDE, both 
wings coloured and marked almost exactly like 4. paraganesa, mihi, Forewing with the discal 
macular band muck broken in the middle, the lower portion below the third median nervule 
being shifted backwards considerably, so that the outer anterior angle of the uppermost spot 
of the lower portion of the band touches the inner posterior angle of the spot above it; in 
A. paraganesa this band is straight and unbroken. Aindwing with a few metallic green scales 
towards the anal angle which are not present in A. paraganesa. FEMALE. UPPERSIDE, forewing 
with the costa, apex, and outer margin all broadly black, the base and disc of the wing to the 
inner margin pale blue ; a whitish spot at the end of the discoidal cell, one beyond in the lower 
discoidal interspace, and two smaller ones below divided by the second median nervule. izd- 
wing with the costa broadly, the outer margin less broadly and decreasingly black, the veins 
black, widening out towards the margin, the rest of the wing pale blue; a fine anteciliary 
white line on either side of the tail. UNDERSIDE, doth wings marked as in the male, but the 
metallic green scales on the imdwing wanting.” 
“A larger species than A. faraganesa, the male conspicuously different, as the blue 
coloration extends over the entire surface except the extreme margin, while in 4. paraganesa 
it is confined toa patch on the disc and base; the opposite sexes in A. paraganesa are also 
nearly alike, while in A. aderrans they are widely different. This is only the second known 
species in the genus; the male was taken by Major C. T. Bingham in the Meplay 
Valley on the 6th January, 1882, the female was obtained also by him at Donat in January,” 
(de Nicéville, 1. c.) : 
The figures shew both sides of both sexes of the type specimens from Burma in my 
collection.

“*WiNGs, broad. FOREWING, somewhat short, exterior margin nearly erect and slightly 
scalloped, ¢hird subcostal nervule bifurcate. HINDWING, short, costa abbreviated, lobed at 
the base, concave towards the end, the afex produced and pointed upwards, exterior margin 
slightly concave below the apex, and very convex in the middle ; ava/ angle lobed ; a spatulate 
tail extending from the end of the first median nervule. /a//i long, stout, apical joint broad 
laterally. Axéenn@ thickened to apex.” yes naked. 
‘* Differs from typical Amdlypodia (A. narada, Horsfield) in the entirely different form 
of the wings ; the forewing having the third branch of the subcostal nervure bifurcate instead 
of trifurcate, as in the male of 4. marada.’’ (Moore, |. c:) 
In the forewing the costal nervure is rather less than halfthe length of the costa, and 
does not reach the level of the apex of the discoidal cell ; the first and second subcostal and 
upper discoidal nervules are equi-distant at their bases, the third subcostal is rather 
long and arises about midway between the apices of the cell and of the wing ; the middle 
disco-cellular nervule is very short, straight, outwardly oblique, lower disco-cellular is about four 
times as long as the middle disco-cellular, concave, slightly inwardly oblique ; second median 
nervule given off some little distance before the lower end of the cell, first median nervule 
bowed downwards near its base. In the hindwing the costal nervure is strongly sinuate, 
bent upwards at its end; the first subcostal nervure is given off some little distance 
before the apex of the cell ; the upper disco-cellular nervule is straight, slightly outwardly 
oblique, the lower disco-cellular is very slightly concave and very slightly inwardly oblique ; 
the second median nervule given off just before the lower end ofthe cell ; the submedian 
nervure is straight ; the internal nervure short, highly sinuous; the abdominal margin
