(1885). 
HABITAT: Burma, Penang, Province Wellesley, Singapore. 
EXPANSE: @,2, 1°3 to 1°8 inches. 
DESCRIPTION: ‘MALE. UPPERSIDE, 40th wings violaceous-blue, margins narrowly 
dark fuscous. UNDERSIDE, 40th wings brownish, with the following spots and fascize 
[of adarker shade of brown than the ground] margined with greyish :—Fovewing with two 
spots in, and one at the end of the cell, two beneath the cell divided by the first median 
nervule, aslightly curved fascia between the end of the cell and the outer margin, which 
is strongly dislocated between the lower discoidal and third median nervules (where it has 
the appearance of a projecting spot, not sufficiently shown in the figure of the female here 
given, though it is distinctly indicated in that of the male), a subcostal spot between the 
first and second subcostal nervules, and a narrow submarginal fascia. AHindwing with six 
basal spots, two irregular medial curved macular fascize, dislocated and united into one from 
the lower subcostal nervule to the costal nervure, a submarginal fascia and three marginal 
metallic greenish spots more or less marked with black near the anal angle. Zaid with 
its apex greyish-white. ody above and beneath with /gs more or less concolorous with 
beneath the cell divided by the first median nervule, a curved fascia (dislocated at the third median nervule) 
between the cell and the outer margin, and a narrower submarginal fascia. Azadzwinxg with seven basal spots, 
a transverse medial fascia commencing at the costal nervure and terminating near the base of the third 
median nervule, followed by a transverse fascia commencing at the lower subcostal nervule, a submarginal 
fascia and three marginal transverse metallic greenish spots, more or less spotted with black, near the anal 
angle. Sody above and beneath more or less concolorous with the wings. FEMALE, UpPERSIDE, doth wings 
with broad darker margins. Otherwise asin the male.”(Déstant, |. c.) 
‘* This is quite distinct from A. mzcale, Boisduval.” (Butler, 1.c.) _ . 
Mr. Hewitson piaced the name Asmdlyfodia adatha on the plate in which he figu ed three male specimens 
of this spec’es. I think this name should apply to figures 29 and 3 only, fig. 31 representing a much larger insect, 
with the discal band on the underside of the forewing unbroken, and has also an additional subcostal spot, besides 
there are other d_fierences of detailin the markings, and fig. 29 one with the band narrower and distinctly broken 
at the third median nervule, and shifted inwards below that vein. His three figures represent in my opinion 
two distinct species ; unfortunately he does not indicate in the letter press from what localities the specimens he 
figured were obtained, but it is probable that the large specimen came from Amboyna and the small one from Sin- 
gapore. In the text (p. 7, n. 32) he sunk his name adatha under mzcale, Boisduval, given by Westwood, in the 
Gen. Diurn.Lep., vol. ii, p. 478, n. 11, as from New Guinea ; and also placed the cleander of Felder from Am- 
boyna as a synonym of m/cale. Subsequently, he ra'sed aduthz to specific rank with ¢leander still as a sy- 
nonym, keeping mzvale as a distinct species (Ill. Diurn. Lep, p. 8, n. 28). I think it extremely probable that the 
species from the Malay Peninsula (? true adtaha), the species from New Guinea (wz/cale), and the species from 
Amboyna (cleander) are all distinct species, and moreover, that the species which Distant has figured from Malacca, 
and Hewitson’'s figures 29 and 31 represent distinct species, asin Distant’s figures the male is shown with no 
black border whatever on the upperside, while Hewitson’s figure 39 shows a rather broad black border, anda 
quite ditierent shade of coloration ; in Distant’s figures the spots and fascia of the underside are no darker 
than the ground, in Hewitsons figure 29 they are much darker, almost black towards the base of the 
wing. Distant says that the specimens he figures and describes agree with Hewitson’s type specimens, but that 
they do not altogether correspond with his figures. AsI have stated elsewhere (p. 228), in the case where specimens 
agree better with Hewitson’s figures than with the specimens standing under the name of the species in his 
collection, the figures should be taken to represent the type and not the specimens, the latter most probably 
having been changed. I must leave this species in this unsatisfactory condition, having no specimens of it ; 
it is to be regretted Mr. Distant did not clear up the matter when he had the opportunity, instead of involving it 
in greater obscurity.

Neither Mr. Distant nor I have seen this species. In the male, as shown in Hewitson’s figure, the coloration 
of the upperside is ultramarine blue, the outer black margins reduced to a thread; on the underside the 
forewing is very heavily marked, all the spots are large, and there are three costal spots; the costal half of the 
hindwing is lilac, all the spots on this lilac portion are prominent and black, the rest are pale brown; the discal 
band oa to be present, but somewhat irregular and obsolete, ‘The species if obtained should be easily 
recognisable,
