Simanggang and Kuching (Sar. Mus.). 
Distribution: Malaya—Mergui and ‘lenasserim to Sumatra 
and Billiton. 
Previously unrecorded from Borneo. ‘Three of the four ex- 
amples in the Sarawak Museum (taken 1894 and 1896) differ 
from Distant’s figure in Rhopalocera Malayana (Pl. XXILL. 
ime 1ES))) ain having a dislocated transverse band on the under- 
side of fore-w ing: but the fourth example, taken near: Kuching 
in August 1911, is normal in this respect. 
Injury. 6, large triangular bite out of hind-margin of 
right hind-wing, reaching as far as the cell and removing ‘rather 
more than half the wing. 
Arhopala alaconia, Hew. 
Amblypodia alaconia, Hewitson, op. cit. p. 14, pl. UL.

Arhopala sarawaca, n. sp. 
Mater. Upperside. Lustrous blue-purple with narrow even 
fuscous hind-marginal borders, a little broader at apex of fore- 
wing, more so across apex of hind-wing; costal margin of fore- 
wing very narrowly fuscous, of hind-wing more than twice as 
broad; inner-marginal fold of hind-wing grey fuscous, a thin 
indistinct white line bordering the anal angle : dark fuscous 
tail white-tipped. Underside. Brown with an iridescent lilac 
tinge, particularly noticeable in the hind-wing. The white 
edging to the spots well pronounced: general appearance of 
the underside like A. ariel, Doherty, but the individual mark- 
ings quite different. Fore-wing: three cell spots well defined 
and in increasing sizes; below the 2nd and 3rd are two irre- 
gular half-formed spots: above the second and slightly interior 
another small spot; small minute white spots above the third 
cell spot suggesting an irregular continuation of that spot to 
the costa; a well-defined transverse band of 6 spots: the Ist 
very small, 2nd, 3rd and 4th fused and sloping outwards, the 
Sth and 6th shifted well in and sloping outwards; hind-
