transparent area of the hind wings is reduced to two spots. The Northwest Indian form has almost entirely 
transparent hindwings, the window extending from the hindmargin round the cell to the subcostal vein; 
vitrea subsp. nov. (8 f), from Mussourie. vitrea. 
P. cyanocera Humps. (=ignea Oberth.) (8g). cf: Resembles the former species, possibly the cd of same? cyanocera. 
Copper coloured spots at the base of the forewings and in the centre of the hindmargin; and a similar spot on 
the thorax. Burmah. 
P. khasiana Moore (8g). ?: also resembles nigrigemma. Body and antennae blackish green above, khasiana. 
with very faint sheen; antennae thinner. Hindwings much more pointed and with two transparent streaks in 
the cell. In the forewings the 2 nd and 3 rd subcostal veins on a short stalk. Only ?? are known from the 
Khasia- and Naga Hills in Assam. 
P. discoidalis Swinh. (8g). Head, collar and a spot at the base of the forewings golden. The broad discoidalis. 
outer portion of the cell of the forewings, eight spots round the cell, the two latter long and further a row 
of spots on the hindwings transparent. In Ihe forewings the 3 rd and 4 th subcostal veins are stalked. Tonkin. 
P. crawfurdi. Head, collar, metanotum and the borders of the abdominal segments reddish golden. 
Wings narrower than in the species already mentioned. Hindwings with a large transparent area on the hind 
border and another small transparent spot, separated from it. On the forewings the transverse band on the 
end of cell is connected behind with the black marginal band. The neuration varies, but the 3 rd and 4 th subcostal 
nervures of the forewings &( least are stalked. Larva according to Piepers black, with rows of brown warts, 
which bear bunches of white hairs. — The North Indian form tenebrosa Btlr. (8 g) is the largest, it is further tenebrosa. 
distinguished, that in the forewings the two upper spots of the row of transparent spots are longer than the 
remainder; the 3 td and 4 th subcostal nervures stalked. — siamensis Oberth. from Renong in Siam, forms a siamensis. 
connecting link in the size of the spots between the North Indian and the Malayan forms of P. crawfurdi. — 
Specimens from the Nicobars, Malacca to Java, Celebes, Amboina, Burn and the Philippines are very variable 
in size, but never attain the length of wing of tenebrosa; in these Malayan forms, the crawfurdi Moore (on crawfurdi. 
the plate misprinted craivfordi, — strigosa Walk) (8g) the two upper spots of the outer row of transparent spots 
are always much smaller than the remainder; in some specimens the 2 nd —4 th subcostal veins are stalked, and 
nearly always the 3 rd radial and the 1 st median of the hindwings. 
P. birmana Oberth. (8h). Resembles the former species, but the wings are much less black, the veins birmana. 
being thinly scaled, and the streak at the end of cell is not connected with the outer border in both wings, 
at least not in the hindwings. Upper-Burmah. 
P. dolosa Walk. (8h). Blue black, with small white spots on the wings especially on the forewings a dolosa. 
central row of three and an outer row of four (2 small and 2 large), and on the hindwings one little spot; 
3 rd and 4 th subcostal of the forewings are stalked. North India; Upper Burmah. 
P. properta Swinh. ( = dohertyi Oberth) (8h). Neuration as in the former species. Antennae blue green, properta. 
Back of head, collar, sihelds and the 5 th and 6 lh (?) or G th and 7 th (cd) abdominal segments reddish golden. 
Forewings with a large transparent area in the cell and a second still larger one behind it, and an outer row 
of four (=2 + 2) transparent spots. Hindwings chiefly transparent. North-India; Upper Burmah. 
10. Genus: Epliemeroidea Ramps. 
Antennae long, pectinated in the cd with the exception of the tip, simple in the female. Forehead 
strongly arched. Palpi projecting somewhat beyond the forehead. Legs long and thin, rear tibia with one 
or two pairs of short spurs, the proximal pair before the middle of the shafts. Neuration peculiar, reminding 
one of some Ifleberis species; forewing cell clubshaped, its front and rear margin touching from the base to 
about 2 / 3 °f its length, the 5 th subcostal and the 1 st radial are generally stalked and the 2 nd radial runs close 
alongside the shaft; in the hindwings the 2 nd subcostal and the 2 nd median are close together and are generally 
weakly developed, the 1st. radial is absent. — Larva (of virescens ) yellow above, the tubercles bearing long 
hairs, through which the larva resembles those of the Syntomidae; on the prothorax on each side a long pencil 
of black hairs which are white at the ends. The dorsal tubercles are mostly pale and bear white hairs, the 
tubercles on the 7 th and 8 th segments are black and have black pencils. The white coccoon quite flat, surrounded 
witl+hairs. Indo-Malayan. 
E. ariel Humps. (8h). Body brilliant green. Veins and borders of wings black. Rear tibia with two ariel. 
pairs of spurs. Antennae in the cd and ? pointed. Assam and Burmah. 
E. flavocincta Humps. (8h, in pi. flavicincta). Like the former, the 3 rd , 4 th and 5 th segments of the abdomen flavocincla. 
(?) yellow; forewings with some yellow at the base. Burmah. 
E. virescens Snell. (8 i). Body blue green. Antennae shorter than in ariel, in the ? with swollen end. virescens. 
Rear tibia with only one pair of spurs (always?). On the forewings the cell, the veins, streaks between the 
veins and the borders greenish black, the base brilliant green; rear tarsi with long scales. Java;’ Sumatra.
