hindwing large; Malacca to Hainan, China, and Formosa; these two tailed forms, which are connected by tran¬ 
sitions, probably occur everywhere. From Formosa a further tailed form is known to me, which is strikingly 
like specimens of $-f. agenor with very light hindwing: $-f. titania form, nov., fore wing sepia-colour, with dark titania. 
stripes; on the hindwing a very small cell-spot, a row of 7 discal patches, of which the 3.—7. are very large, and 
a row of large marginal spots white, the posterior marginal spots slightly yellowish, the black vein-stripes 
thin, beneath the cell-spot is wanting and the discal patches are abbreviated basally. — anceus Cr. is the race 
which inhabits Sumatra, Nias and Batu. In the $ the upper surface is very similar to that of the J of agenor ; 
beneath the cell-stripes and discal stripes of the forewing are broad and the distal-marginal area of the hindwing 
is blue-grey, often somewhat yellow at the anal angle, in exceptional cases the yellow tint is deeper and more 
extended. In this race also the $ does not occur everywhere in the same forms; the abdomen is posteriorly nearly 
always yellow; the hindwing in the dark forms is above more densely scaled with blue than in the other Malayan 
races, the basal spot of the forewing above is red or white, not yellow, the tailless forms with white band on the 
hindwing always bear beneath two rows of black spots and the tailed form is likewise easy to distinguish from 
the corresponding form from other districts, as described below. The principal types of the $ are: $-f. erebinus erebinus. 
Haase (30 a), abdomen black or posteriorly yellow; forewing dark, between cell and apex more or less extended 
white, basal spot always red; hindwing above (as also the forewing) paler than in the <$, but quite as densely 
scaled with blue; Sumatra. §-f. trochila form, nov., forewing with red basal spot and often a distinct white patch trochila. 
between cell and apex; upper surface of the hindwing at least in the middle scaled with blue, distally pale, in 
addition to the black submarginal spots with a row of smaller discal spots; Sumatra, Nias, Batu. $-f. anceus Cr. anceus. 
resembles the preceding form, but the basal spot of the forewing is white; Sumatra, Nias. $-f. sitolensis Fruhst., sitolensis. 
similar to anceus, but the upper surface of the hindwing distally more or less yellow, the apex of the cell also 
yellow; only known from Nias. $-f. gerania form, nov., forewing with white area between cell and apex, the gerania. 
basal spot red; hindwing with broad yellowish white band, which at least beneath bears two rows of black spots, 
abdomen posteriorly yellow; Sumatra. $-f. ityla form, nov., like the preceding, the band of the hindwing white- ityla. 
yellow, the black submarginal spots very large, the distal margin blackened, the abdomen black; Nias. $-f. 
butis form, nov., tailed, the basal spot of the forewing red, the border of the hindwing broadly black, the margin butis. 
itself and the veins less deep black, the last white discal patch distally orange-j^ellow, sometimes also the last 
but one; abdomen yellow, a dorsal line and the under surface black; Sumatra. $-f. hellopia form, nov., like hellopia. 
the preceding form, but all or almost all the white discal patches of the hindwing distally yellow; Nias, Batu. 
The tailed form is the rarest in all the localities; the tail is sometimes scarcely widened at the tip. — memnon L. memnon. 
{S — atrovenatus Goeze, arbates Zinken, memnoides Fruhst.) (33 a). the blue streaks of the upper surface 
in general shorter than in the J of anceus, on the hindwing commonly not reaching the cell; beneath the cell- 
stripes of the forewing less distinct and the discal stripes less broad basally and commonly not touching the cell; 
the distal area of the hindwing beneath blue-grey as in anceus, usually somewhat yellow posteriorly. In a $ from 
Java (Sukabumi) the streaks of the upper surface are glossy blue and cover almost the whole hindwing, also 
beneath the stripes of the forevving and the central port of the hindwing are cyaneous blue: ^-ab. sericatus Fruhst. sericatus. 
The $ as in anceus extraordinarily variable; the abdomen either entirely black or the sides and back with the 
exception of a dorsal line yellow; the hindwing above rarely with distinct glossy blue scaling; the basal spot of 
the forewing red or yellow, never white; the forms with broad, white area on the hindwing have also beneath 
only one row of black patches. We treat the specimens from Borneo, Bunguran, Banka, Bawean, Java and 
Bali as belonging to one geographical race, but several of the ^-forms are confined to one or other of the islands, 
so that we have here no more than in anceus and agenor a geographically uniform subspecies. $-f. gyrtia form, nov., gyrtia. 
forewing above with red basal spot and white subapical area, otherwise very dark; hindwing almost pure black, 
distally with very slight yellowish scaling; Borneo, corresponds to $-f. erebinus Haase from Sumatra. $-f. dobera dobera. 
form, nov., forewing with sharply defined, black basal area, which does not reach the base of the 
lower median, and red basal spot, otherwise broadly striped with white, these stripes broadest towards 
the base and distally shaded with blackish brown, so that the forewing recalls the of pryeri and 
thunbergi; hindwing black, distally somewhat paler; Borneo. $-f. laomedon Cr. (= memnoides Fruhst.) (30b), laomedon. 
fore wing more or less brownish sepia-colour, with black base and black interneural stripes, red basal spot and 
usually a whitish subapical area; hindwing distally sepia-colour to yellow-grey, with two rows of black spots; 
abdomen black; Bunguran, Borneo, Java, Banka; the commonest form. $-f. hiera form. nov. (30 b), forewing hiera. 
as in the preceding form, hindwing with broad white or yellowish band and a row of black submarginal spots, 
the black discal patches absent also beneath, abdomen black; Java, Banka. $-f. imperiosa Fruhst. (48 b). imperiosa. 
Forewing white before the distal margin from the subcostal fork to the hindmargin, this band-like area posteriorly 
widened; the yellowish white area of the hindwing reaches the cell, in the apex of which a small white spot is 
placed; the extreme tip of the abdomen yellow; only known from Banka, where this form appears to be common. 
$-f. isarcha form, nov., forewing as in $-f. laomedon of lighter or darker sepia-colour, with sharply defined black isarcha. 
basal area and red basal patch; hindwing for the most part white, distally with yellowish tinge and a row of black 
patches, basally the white area reaches to about the middle of the cell, sometimes almost to the base; abdomen 
black; Java to Bawean, on Banka represented by the preceding form, on Borneo by the following one. $-f. 
venusia form. nov. (48 b), abdomen yellow as in the tailed forms, a dorsal line and the underside black, forewing venusia.
