is intermediate between selangora and typical militaris, the black markings being mostly present, but small. 
It was described from Perak, but is commonest on Sumatra and is also recorded from Borneo. — jessica Swinh., 
described from the Nicobars but apparently also common on the Andamans, is possibly a separate species, as 
it is not only smaller but has also a slightly narrower forewing, etc. Proximal costal half-band of forewing less 
oblicpie, the rounded spot behind base of 2nd median wanting or punctiform, the mark near base of hindmargin 
enlarged. 
B. porphyroides Prout. founded on a single from the Andamans, is a puzzling form, possibly an 
extraordinary aberration of the following species, but with the antemedian band narrower, more as in subrepleta, 
the terminal band of the hindwing macular throughout. Suffused all over with purple, showing only a couple 
of yellow dashes at the base of the forewing; the dark markings shadowy; 5 white outer spots of fore wing clear, 
arranged almost as the fust 5 of alloides, but with the last (in cellule 2) small. 
D. alloides Prout (9 a). About the size of jessica and likewise rather narrow winged. Proximal 
markings broader than in either militaris or subrepleta, the anterior half-band more curved, ending in a knob 
behind the base of the 2nd median, as in militaris. White outer band characteristically formed, especially the 
narrow, very sinuous mark behind the 2nd median. Hind wing with cell-spot confluent with a posterior patch, 
as in subrepleta. As the genitalia are closely similar to those of militaris, it is just possible that this, and not 
jessica, represents that species on the Andamans. — ab. lutescens ab. nov. has the purple-black colouring entirely 
suppressed, the dark markings mostly only indicated in rather deeper orange, on the apical half of the forewing 
in olive-grey. 2 in Mus. Tring. 
D. subrepleta is distinguishable from militaris by the shape of -the proximal markings of the forewing 
and the band-like extension of the cell-spot- of the hindwing. — excubitor Moore (6 e), described from Upper 
Tenasserim, but distributed from Sikkim to Siam, the Andamans and even Perak, Java and Bali, probably 
only in the mountains, is yellow rather than orange and has the black markings rather slender, the antemedian 
bands not meeting behind the 2nd median. — ab. sodalis Moore is a rare modification, with the black markings 
less slender, etc., but still with the antemedian band broken behind the 2nd median vein. — semifracta Prout 
differs from excubitor in having the abdominal-marginal black spot of the hindwing reduced, not confluent 
with the cell-spot. Hainan. Some specimens from Siam are transitional. — nias Prout has the ground-colour 
yellow, not orange as in subrepleta. Mas and W. Sumatra. (Fort de Kock). Also, according to Semper, on 
the Philippines. — subrepleta Walk. (6 e), in its typical, deeply coloured forms, seems to be almost confined 
to Borneo and the Malayan Coast. On Sumatra there is some tendency to develop transitions towards the 
race nias, but I do not separate the Sumatran, considered in the aggregate, from the name-type. 
B. cancellata Bastelb. (6 f) is probably related to prunicolor, but has no yellow on the forewing, the 
proximal part of the hindwing scarcely yellowish, the fine lunulate yellow submarginal line conspicuous. N. 
Borneo: Kina Balu. 
D. prunicolor Moore is rather smaller than subrepleta, the fore wing in the S' narrowed, the hindwing 
in both sexes with the distal margin rather straight between the 2nd subcostal and the 3rd radial. The dark 
parts are less black, more purplish, than in subrepleta, the white and yellow parts much reduced, especially the 
yellow basal streaks of the forewing, which in the name-type are almost obsolete; the spot in the cell is white, 
not yellow. — ab. bcllissima Moore has the white and yellow markings less extremely reduced. Ceylon. Larva 
green, with yellow lateral stripe; spiracles black-ringed; legs red-speckled. On Carallia. Pupa purple-brown. 
D. plena Walk. (= manillaria Guen., balistaria Guen .) has the <$ hindwing nearly as strongly elongate 
and bent at the 3rd radial as in longimacula (6 f). Certainly related to that species, but somewhat intermediate 
towards subrepleta in that the proximal markings of the forewing are yellow, the black bands of the hindwing 
broad. Philippines, chiefly on Luzon, but reaching Mindoro. Larva green, with darker dorsal stripe, abdomen 
with a light greenish yellow lateral line on the abdomen; single blue dots between this and the dorsal stripe; 
spiracles dark-blue; legs brownish. Pupa brown. 
B. longimacula Semp. (6 f). Recognizable at once by the more extreme shape, reduction of the dark 
markings, absence of yellow from the forewing, etc. Palawan. 
B. latiplaga Warr., from Celebes, somewhat resembles the two preceding, but has much broader black 
markings, including a complete border to the hindwing. The name-type has the spots on the forewing, and 
often on the proximal part of the hindwing, bluish white. — ab. chrysostathes Prout has the spots almost entirely 
bright yellow. 
B. contraria Walk. (7 e), from Central and S. Celebes, differs from latiplaga in the arrangement of 
the markings. — melleata Warr. (7 d) is perhaps a yellow form of contraria. Chiefly from N. Celebes and Palos
