242 LYCENIDE. ARHOPALA. 
Hapitat: Sumatra (ezwz7tson), Borneo (Druce), Malacca (Butler), Mergui, Tenasserim 
Valley, Burma. 
ExpANsE: ¢, 9,1°7 to 2’0 inches, 
DESCRIPTION : * MALE. UPPERSIDE, Goth w7ngs lilac-blue, the margins black, very narrow. 
Forewing with a large medial spot of a somewhat different colour, not seen except in a certain 
light, and not produced by any unusual arrangement of the scales. Unpersipr, both wings 
rufous-brown. Forewing with the transverse band broken, composed of seven parts, three 
together, the fourth projecting outwardly from the rest, the three following further from the margin 
than the fourth. FEMALE. Uppersipr, both wings violet-blue. Forew7ng with the costal margin, 
the apex, and the outer margin broadly black, the veins black. Aidzwing with the apex and 
outer margin broadly dark brown, the veins black.” 
‘““The spots on the underside of the male are less distinctly marked than those of the 
female. This species scarcely differs on the underside from A. adonias [Hewitson, from Java], 
and A. eumolphus, Cramer. It is nearly allied to A. agaba, Hewitson ; on the upperside the 
two species are alike.” (ewé?tson, 1. c.) 
Mr. Distant did not obtain this species in the Malay Peninsula, but he figures the opposite 
sexes from specimens from Malacca contained in the British Museum. ‘hese figures shew 
the male with a very broad outer black margin to both wings on the upperside. This is almost 
certainly incorrect, and either two varietal female forms of this species. or females of two 
different species, have been figured ; Hewitson distinctly says that the margins are very narrowly 
black in the male ;in one place that A alosia is the same on the upperside as A. agaba ; 
and in another describes a medial spot of a different colour from the rest of the wings on 
the upperside of the forewing in the male* ; this spot is certainly not present in 4. agaba. 
A, atosia in both sexes may, however, be easily known from 4. agada by having the discal 
band on the underside of the forewing in both sexes broken below the fourth spot from the costa, 
and by the fourth spot being nearer the margin than the rest ; in 4. agada the band is nearly 
straight, unbroken, all the spots one below the other. Herr P. C, T. Snellen(Midden-Sumatra, 
Lepidoptera, p. 21) appears to consider that A. avosta is a variety of the female of 4. exmolphus, 
Cramer. Inthis, however, I think, he is incorrect. Hewitson describes both sexes of 4. avosia, 
and figures the female. which from the figure may at once be distinguished from the female of 
A, eumolphus by having the purple area on the upperside of much greater extent. 
Ihave received two male and three female specimens of this species from Singapore, kindly 
sent me by Mr. W. Davison, and have also seen two males and three females collected in 
Mergui and the Tenasserim Valley, Burma, by Mr. Doherty. They agree in coloration and 
markings in both sexes almost exactly with the species I identify as 4. antimuta, Felder ; 
they are also of about the same size, but may be known by having a tail, which 4. antimuta 
lacks. In the male the outer black border is half as wide on the upperside as in A. antimuta, 
The figure shews both sides of a male specimen from Singapore in my collection, 
794. Arhopala abseus, Hewitson.

EXPANSE: 6, 2, 1°4 to 1°5 inches. 
DESCRIPTION: “FEMALE. UPPERSIDR, both wings bright blue, the margins broadly 
brown. UNDERSIDE, both wings ferruginous, Forewing with a broad transverse band in the 
middle, the usual band nearer the apex, at first broad and of equal breadth, then broken nearly 
apart in the middle and projected towards the margin, the lower part becoming narrower to 
its lower extremity. H/indzwing lilac in the middle, with a light spot on the middle of the costal 
margin.” (ewitson, 1. c. in Cat. Lycenide B. M.) 
* This very curious feature is only found in one other species, as far as I know, the A. antimuta of Felder.
