90 MR. G. T. BETHUNE-BAKER : A REVISION OF THE 



In a male specimen from Perak the blue has a violet tinge, but is almost as lustrous 

 as in the usual form. 



De Niceville (I. c.) has referred to this species under the name agelastus Hew. In 

 his fine collection of this group, which he has so kindly lent me, is a large series of 

 this species, the females preponderating by two to one male, taken mainly in Burma 

 and Tenasserim, but there are specimens also from Mergui, Penang, and Bheeling. I 

 have no doubt, from the single example of Doherty's species pastorella before me, and 

 from his figure of it, that this is identical with moolaiam.

6 . Upperside : both wings soft violet, with a brownish shade in side-lights ; 

 primaries with costa and outer margin very narrowly brown ; secondaries with broad 

 brown costa and very narrow outer margins. Underside clear ochreous brown with 

 slightly darker spots palely encircled. Primaries with three increasing cell-spots, below 

 the third a small one in the lower median angle ; transverse catenulated band composed 

 of six spots fractured below the fourth, the upper four have a slight outward inclination, 

 almost a curve, the first spot on the costa being very small, the fifth is shifted well 

 inwards, and the sixth slightly inwards also ; there is the least trace of a submarginal 

 row ; the submedian area is slightly paler than the ground-colour. Secondaries with 

 four basal spots below each other, the second and fourth shifted slightly inwards, 

 followed by three larger spots with a slight inward inclination ; cell closed by a subovate 

 spot, below which is a small one in the lower median angle ; transverse catenulated 

 band composed of eight spots in pairs, the first two quite separated and distinct, the 

 lower of which is shifted well outwards, the third and fourth confluent, shifted well 

 outwards, fifth and sixth confluent, shifted inwards, seventh angular spot confluent with 

 the eighth and shifted again inwards ; submarginal row distinct, marginal row less 

 distinct ; at the anal angle is a very large blackish spot extending into the next nervule 

 space and well covered with a bright pale blue metallic spot, of which there is a slight 

 trace in the second median nervule space. 



This species can at once be separated from moolaiana Moore by the violet colour of 

 the upperside, which in Moore's insect is almost morpho-blue ; the underside is also 

 somewhat different as described. From mornata Feld., a still closer ally, it is more 

 difficult to separate ; it has, however, a much duller upper surface and is not so blue, 

 whilst beneath the pattern is much more distinct and both transverse bands are more
