towards the anal angle, apical area very broadly black ; secondaries with a broad costa 

 and rather narrow posterior margin. Under surface ochre-brown, with darker markings 

 palely but faintly encircled. Primaries with three small increasing cell-spots, below the 

 third a small one in the lower median angle ; transverse band composed of six continent 

 spots, with a very slight curve in the three upper ones, the whole band being slightly 

 oblique outwards; submarginal and marginal row obscure; submedian area pale; sub- 

 discal area dark. Secondaries with four, quite small, basal spots, the fourth shifted well 

 inwards, followed by three larger ones below each other, the second shifted slightly 

 inwards, ami the third the largest of the three; cell closed by a. subreniform spot, 

 below which is a very small one in the lower median angle ; over the spot closing the 

 cell are two others (usually forming the two upper spots of the transverse band) above 

 each other, the lower one being the larger; transverse band composed of six spots 

 beginning on the upper discoidal nervule, the first two continent, the second shifted 

 very slightly outwards, third with the inner margin only shifted inwards, fourth almost 

 confluent with the third, fifth angular spot touching the sixth and shifted well inwards; 

 submarginal and marginal rows obscure ; a small black spot at the anal angle, preceded 

 by two others, which are more or less covered with pale greenish-blue metallic spots. 



Arhopala i>erissa Doherty is a very close ally of this species; in fact, 1 am extremely 

 doubtful if they are not one and the same, but as I have so little material I deem it 

 best to keep them distinct for the present. Doherty's species has the spots and fascia 

 wider and larger, and the borders of the upperside broader. 



De Niceville says (Butt. Ind. I.e.) that Mr. Doherty showed him certain specimens 

 taken at Mergui and in Tenasserim, and that some of them bore traces of a circular 

 patch of differently shaded scales on the upperside of the fore wing, as in A. atosia 

 Hewitson. I have these specimens now before me, named agelastus by de Niceville ; 

 but they are moolaiana Moore, and not Hewitson's species: the reference to atosia 

 should therefore be eliminated from the account of agelastus in de Niceville's work.

There appear to be two forms of this species, differing on the upperside onl} ; tin 

 type is rich purplish blue, and 1 have several specimens of this colour, oi both 

 before me, but 1 have also in de Niceville's series several of both sexes which ate 

 brilliant pale lustrous blue, without any admix! lire of purple at all ; the underside is 

 precisely the same in every respect. I notice the same thing in tounguva Gr.-Smith, 

 but the difference is by no means so marked.
