Bay, but Dr. Martin took it in the Central Mountains with contraria. 
D. auroguttata Warr. (6 d) rather recalls translucida, but the very narrow forewing and bent (at the 3rd auroguttata. 
radial) hindwing associate it with the present group. Markings white, excepting the submarginal spots of 
the hindwing; forewing with the spot in and behind the cell generally large, the others small; hindwing with 
a large proximal patch, often almost as in discalis (7 c). Sula Islands. 
D„ discalis Walk. (7 c) is scarcely variable and cannot be confused with any other species. Known discalis. 
from the Malay Peninsula, Sumatra and Borneo, the type only recorded as from the ,,East Indies”. 
B. minervaria Guen. is a large and round-winged species with the forewing predominantly light blue- minervaria. 
grey, the hindwing bright yellow. The locality of Guenee’s type was unknown, but his description fits to 
specimens from Burma and Siam. — pugnataria Guen. {— horsfieldi Moore) (7 b), from Java, has in addition pugnataria. 
a yellow posterior and distal patch on the forewing. — patula Walk. (= latigrisea Prout ) is smaller than the patula. 
other forms and has the anterior part of the hinclwing grey (concolorous with the forewing), this shade bounded 
by the median vein as far as the cell-spot, then by the 2nd radial and finally by the 2nd subcostal and containing 
beyond the postmedian spots a single yellow spot. Walker’s type was from Cambodia, mine from Penang, 
and as the form has been taken with minervaria in Siam (see Tams, Journ. Nat. Hist. Soc. Siam, vol. 6, p. 275) 
it must be rather a species or a constant aberration. 
D. malayanus Guer. is the first of a group of blue-grey species in which the yellow markings are malayanus. 
still further restricted or altogether wanting. In the present species tire ground-colour of the forewing cuts 
the black border at the veins. Guerin’s type, from Malacca is a rare form with a long, but narrow, yellow 
streak along the abdominal margin of the hindwing, but specimens from the Malay Peninsula in general have 
a more or less developed yellow patch on this margin near the anal angle and the same forms inhabit the Battak 
Mountains of N. E. Sumatra and occur as rare aberrations elsewhere: ab. luteomaculata Grunb. (7 b, as recessa). luteomacu- 
— recessa Walk. (= proba Btlr.) is the commoner form, entirely without yellow marking. Borneo (type), lata - 
Palawan, parts of Sumatra and as an occasional aberration in the Malay Peninsula. Butler’s $ allotype was 
said to be from Darjiling, but this requires confirmation. — ab. supergressa Warr. said to be from Borneo, is supergressa. 
(unless the locality be erroneous) unique for that country in that the yellow patch of the hindwing is as highly 
developed as in extreme examples from the Peninsula. 
D. palmyra Stoll (= transversa Wall.) (7 b) not only lacks the yellow on the hindwing, but also on palmyra. 
the anal end of the abdomen. The black border of the forewing is solid. Stoll’s type was from Tranquebar, 
Walker’s from Ceylon, the best-known locality. Flies very slowly by day and is very tenacious of life. Larva 
yellow, the thorax black-spotted, the abdomen with bluish, black-dotted dorsal and lateral band. On Garallia 
integerrima. Pupa of within a rolled leaf; reddish, with 2 large black eye-spots in front, which show at the 
entry of the roll and present the terrifying appearance of the eyes of a small reptile. 
D. percota Swinh. (7 b) differs from palmyra in the large black apical patch of the forewing. Distributed percota. 
in western India from Bombay to Trevandrum. At Matheran it is abundant in cold weather, flying by day; 
very rare in the summer. Longstaff (,,Butterfly Hunting”, p. 391) apparently regards it as a race of palmyra 
and this may well be correct. 
D. nelera Swinh. Less large and broad than the two preceding and generally with a row of small yellow nelera. 
terminal spots (sometimes confluent) on the posterior part of the hindwing. Forewing relieved with whitish 
between the subterminal and terminal black bands; antemedian costal streak straight and not definitely macular. 
Local, but swarming on the tops of the mountains of Matheran and Kbandalla for about a week every cold 
season. It flies by day and by night. 
D. azurea Bastelb. (7 c), from the mountains of North Borneo, is said to differ from the following azurea. 
species in the more angled hindwing, less confluent antemedian bands of forewing, absence of spot of hindwing 
posteriorly to the discocellulars and reduction of the yellow spot. The description and figure also point to a 
bend in the anterior antemedian band which is not present in any specimen of transducta which I have seen. 
D. transducta Walk. (= doubledayi Snell., malayanus Walk, nee Guer., malayaria Guen.) (6 f) is transducta. 
a variable species, less round-winged than malayanus, generally more bluish, the black border of the forewing 
generally narrower, never sharply cut by the ground-colour. Weymer and Bastelberger separate transducta 
and doubledayi (both from Borneo, the former certainly and the latter probably from Sarawak), Weymer 
stating that transducta is smaller and broader-winged. I am, however, unable to draw a line in the very ample 
series before me. More or less typical forms are found on Nias, the Batu and Mentawei Islands, Sumatra, Natuna 
Islands and Borneo. The yellow posterior patch on the hindwing is generally well developed, especially in
