confounded with it. But it is at once recognised by the yellow hair of the coxae; moreover, the 
metanotum bears yellowish grey hair at the sides and the mesonotum a yellowish grey spot on each side. 
Forewing above similar to that of E. vetula, but there are two yellowish white transverse stripes between 
base and first pair of spots, the stripes having a bluish tint on account of the dark ground, the sub- 
marginal spots, moreover, especially the last one, are more strongly developed. On the underside the 
fore wing bears at and near the base a yellowish streak in front of and a spot in the cell; the submarginal 
spots have the same colour as the macular bands. The hindwing is less extended black above and 
beneath than in E. vetula , the abbreviated black band and the marginal border usually being narrower 
than in vetula. The genitalia do not appear to differ. — Java, known to me from the East and West 
of the island; rarer than vetula. 
E. vetula. Underside of thorax black, the hair of the coxae not being yellow. Head and an¬ 
terior portion, of thorax spotted with white or yellowish. Forewing with two white or yellow bands, 
which are either interrupted or entire, and a row of submarginal spots, which are always present at least 
beneath; at the base some bluish dots, but there is no distinct yellow basal cell-spot. Hindwing red, 
beneath paler than above; markings similar to those of the preceding species. Indo-Malayan, distri¬ 
buted from Northern India to Palawan and Java. Larva, according to Piepers, on Dioscorea and. Smilax; 
whitish grey to slaty grey, beneath darker, above with black longitudinal stripes, head, pronotum, a large 
dorsal spot on segment 11 and a spot above the anal legs orange; the lines accompanied by black 
dots. — vetula Geyer (1 c). Postmedian band of forewing interrupted, and the submarginal spots nearly as vetula. 
yellow as the bands. Java, only known to me from the western districts of the island. — irenea Bdv. irenea. 
(1 c) differs from true vetula especially in the submarginal spots of the fore wing being white; more¬ 
over, the hindwing has a more yellowish red tint, particularly on the underside. The spots of the 
discal band of the forewing are frequently united, but the band always remains irregular. Sumatra 
and Nias, presumably also on the other islands off the west coast of Sumatra; very abundant on Nias. 
The specimens from the Malay Peninsula and Penang lead over to the next subspecies; the markings of 
their forewing are sometimes all white. — fasciatrix Westw. Both bands of the forewing frequently nar- fasciatrix. 
rower than in true irenea, the posterior spot of the antemedian band shorter and as a rule more distal than 
in irenea. In name-typical fasciatrix the bands of the forewing are yellow, while they are white and 
narrow in f. communis Bull. (= vetula Bdv. pt.) (lb). Assam and Burma. — communicans Walk., from communis. 
Cambodja, of which we have only seen the name-type (in the Oxford Museum), is a transition towards 
the following form. - bijugata Walk. (= solicita Swinh.) (lb) occurs in Dutch and British Borneo (inch bijugata. 
of Sarawak) and appears to be very abundant. The bands of the forewing are not interrupted, the 
outer one is usually obviously broader than the proximal one, and the submarginal spots are 
reduced or absent above. — palavanica subsp. nov. The bands of the forewing uninterrupted as palavanica. 
in bijugata, but the onter band narrower than, the proximal one and the white submarginal spots near¬ 
ly as well developed as in irenea; moreover, there is a yellow dot at the hind angle below the discal 
band. Palawan. — No forms of E. vetula are known from the Philippines. 
b) The naked sole of tarsal segment 5 of J not or but slightly elevate in keel-shape, this segment of the fore 
and mid tarsi of the $ with 4 rows of spines and a few yellowish curved hairs. The black spots on the underside of the 
abdomen, if present, are placed at the apices of the segments.

E. mundina spec. nov. (-fa). <$: Very similar to E. vetula irenea, larger, and very different in mundina. 
structure. The white spots on head and thorax small. Coxae with yellow' hair; abdomen beneath 
with small black dots at the apex of some segments (type) or entirely yellow; segment 1 above 
broadly bordered with yellow, the yellow margin of segment 2 interrupted, segment 8 above black with 
a few yellow hair-scales at the apex, its sides being yellow, the ventral lobes longer and narrower 
than in E. vetula, yellow with the base and a lateral stripe black, claspers brownish black, harpe 
curved upwards and very sharply pointed; anal tergite pointed, densely clothed with long stiff yel¬ 
lowish hair on the sides as in the following species. Forewing above with a small yellow basal cell- 
spot and two interrupted yellow oblique bands, of which the outer one is less oblique posteriorly than 
in E. vetula; submarginal spots white. Hindwing as in vetula. On the underside the forewing bears a basal 
costal dot and further distally a larger yellow cell-spot; the bands obviously less oblique than in 
vetula, the exterior one entire, the yellow spot in front of the hind angle as large as the sub- 
basal cell-spot. Hindwing as red beneath as above, but the bluish white submarginal spots larger. 
Length of forewing 34—35 mm. — Two <$<$, one from Mt. Tahan and the other from Perak (type), Malay 
Peninsula, in Mus. Tring. 
E. darocana Druce (4 a), which is erroneously treated by Hampson as identical with bijugata, is larger darocana.

the stripe on the patagia longer than in vetula; coxae yellow, fore tibia, underside of femora and
