glossed with vinous Forewing with a narrow white discal line formed of short lunules 
between the veins, that portion below the first median nervule shifted inwards ; a double sub- 
marginal series of short white lines, more diffused than the discal line, placed between the 
veins, which give the appearance of six increasing spots of the ground-colour defined with 
white. Azxdwing witha discal white line as in the forewing, but much more distorted and 
irregular ; an obscure similar basal line, and a submarginal very dentate one ; the area beyond 
the latter irrorated with whitish, including an obscure rounded ferruginous spot in the first 
median interspace [sometimes centred with black]; a fine white anteciliary line obsolete 
anteriorly. Cz/éa brownish-ferruginous throughout.” 
Allied to Rapala [Surendra] amisena, Hewitson, who describes and figures the female 
while Mr. Distant figures the opposite sex, both from Singapore. Differs from the same [female] 
sex of that species, judging from the figure and description only, in having the purple area of the 
upperside of the forewing of less extent and sharply defined (in R. amzsena it appears to be 
suffused over nearly the whole wing, with no sharp edges), and on the underside of both wings 
in the markings being fewer and white throughout, instead of dark fuscous ; with no trace of 
the dull light blue irroration at the anal angle of the hindwing, with a lunular black spot 
between the tails, described by Hewitson as occurring in his “ Amdlypodia” amisena.” 
(de Nicéville, 1. c.) 
Mr. Otto Moller possesses a single male of this species taken in Sikkim on Ist Aftgust, 
1888, and four females taken in March, May, and July, all at about 1,500 feet elevation. 
Colonel Swinhoe possesses a single female example, also from Sikkim. Inthe Phayre Museum, 
Rangoon, is a single male taken in the Karen Hills, Burma, in March, 1887. It differs from 
the type specimen described above on the upperside in having the purple coloration of a 
lighter more blue shade and more extensive, the ground-colour of the underside more red- 
dish. These slight differences seem to be hardly of specific value, and may be due to season, 
the Burmese specimen having been captured in the dry season, most of the Sikkim ones in the 
middle of the rains. 
The figure shews both sides of the type male specimen from Sikkim in the collection 
of Mr. Otto Moller,

* Allied to Azdaspa, [Moore,= Rapala, Moore]. FOREWING, less triangular in form, the 
exterior margin slightly convex, no tuft on the posterior margin of the male. HiInDwiNG, 
less produced hindwards, no costal depressed granular spot, tail shorter.” (JZoore, 1. c.) 
In the forewing the costa is straight, slightly emarginate in the middle, the outer margin is 
convex, the inner margin straight ; the costal nervure ends opposite to the apex of the discoidal 
cell ; the first subcostal nervule is bent upwards soon after its origin and almost touches the costal 
nervure in the male, well separated in the female ; the base of the second subcostal nervule is 
nearer to the base of the first than to that of the upper discoidal nervule ; the third subcostal 
emitted about midway between the apices of the cell and of the wing ; the middle disco-cellular 
nervule originates from the upper discoidal soon after the latter is given off from the sub- 
costal nervure, the disco-cellular nervules are nearly upright, only slightly outwardly oblique, 
both are slightly concave, the middle one rather shorter than the lower ; the second median 
nervule is given off some little distance before the lower end of the cell; there is no long 
thick tuft of hairs turned upwards from the inner margin near the base in the male asin so 
many allied genera. In the hindwing the costal nervure is very short, not nearly reaching the 
apex of the wing; the disco-cellular nervules are of nearly equal length, very straight and 
outwardly oblique ; the second median nervule originating just before the lower end of the 
cell ; there is a depressed (as seen from above) semicircular glandular patch of scales in the 
male placed above and touching the subcostal nervure, its outer edge not reaching the base of
