S. roseivena Hmps. (13 d). Forewings pale yellow, traversed by a net of rosy-red veins; hindwings roseivena. 
purple-pink. Burmah. 
3. Genus: l^sigosi Wkr. 
This genus, with about 30 forms, contains only small species, some of which have already been dealt 
with in Vol. II, p. 51, and figured there on t. lib. Except one species living on the Cape, all the forms are Indo- 
Australian, and 8 species of them live in the Island of Borneo which, like New-Guinea, seems to represent a 
kind of a central range for the genus. Characterization of the genus vid. Vol. II, p. 51. 
E. dissozona Meyr. (18 m) is one of the largest species and so peculiarly marked that it cannot be dissozona. 
mistaken for any other, two transverse bands approaching each other at the proximal margin traversing the 
almost purely yellowish-white forewing. Above the anal angle sometimes a small dark marginal spot. From 
New Guinea. 
E. tricolora B.-Bak. (181). Forewings white, at the base a small, greyish-brown dot and a subbasal tricolora. 
costal spot, a large, greyish-brown, middle inner-marginal spot, and a small costal spot, extending through 
the cell; in the cell a dark dot; the whole postmedian area brownish-grey with an interrupted and very irregular 
white submarginal line; hindwings unicolorously pale ochreous-yellow. 24 mm. Dinawa, Aroa River; August. 
— Similar to aequalis, but easily discernible by the colouring of the postmedian area and by the pale ochreous- 
yellow hindwings. -— conflua B.-Bak. (18 1) differs from tricolora merely by a different whitish marking of the confhia. 
forewings and a slight grey darkening of the hindwings. Dinawa (New Guinea), in August and September. 
E. transfasciata Rothsch. antennae brick-red, head creamy-white; thorax purple chocolate-coloured, tmnsfascia- 
tegulae, base of patagia and the anterior part of the thorax creamy-white; abdomen buff. Forewings creamy- 1,1 • 
white; curved antemedian and postmedian bands and a marginal spot between veins 1 and 7 purple chocolate- 
brown. Hindwings buff, at the apex a dark spot. Length of forewings: 13 mm. Cumusi River in British New 
Guinea, in July. 
E. sordidata Rothsch. (J: antennae brown; head and thorax dirty white with grey spots; abdomen sordidata. 
dirty buff. Forewings white, 2 spots near the base, a broad antemedian and postmedian, somewhat darkened 
transverse band and one at the margin, connected with the postmedian one by broad horizontal streaks, dull 
brown. Hindwings buff. Length of forewings: 15 mm. Setekwa River (Snow Mountains), Dutch New Guinea, 
September. 
E. aureoplagiata Rothsch. The has iridescent golden yellow head, antennae and thorax, the abdomen aureopla- 
being buff. Forewings slate-grey; base, costal-marginal area and apex broadly iridescent golden yellow, with giata. 
a border being proximally lustrous violet ; a spot connected with a purple spot towards the base at the proximal 
margin and bordered by it, is golden yellow. Hindwings buff. Length of forewings: 11 mm. Cumusi 
River, July. 
E. aequalis Wkr. (== imposita Wkr.) (181) is larger than the preceding, somewhat similar to the aequalis. 
form tricolora, but the brown bands still more separated, so that the white becomes the predominant colour 
on the forewing and thorax. The postmedian brown band indented behind the cell from the direction of the 
margin. Hindwings yellowish-grey. — In ab. trifascia Wkr. the two brownish basal dots in the forewing are trifascia. 
replaced by a dark basal stripe at the costa; the antemedian band more uniform and the brownish marginal 
band scarcely dentate. From Borneo. 
E. bipunctata Wkr. (= trifasciata Snell.) is much smaller than aequalis, dirty whitish-grey. On bipunctata. 
the forewing the dark antemedian band is much narrower in the cell, so that it is divided into a smaJer spot 
at the costa and a larger one at the proximal margin; the postmedian band is coherent, but narrow and irregular; 
before the border only traces of small dark spots. Widely distributed and not rare, from India and Assam 
across the Sunda Islands and Malacca to the Moluccas. — In trifasciata Moore from Ceylon the colour of the trifasciata. 
forewings is clearer and lighter, and the antemedian band is widened at the costa and above the proximal margin. 
— ab. basipuncta Hmps. is almost like the typical form, but the forewings somewhat less strewn with grey, bnmpuncta. 
the anterior band in the cell quite interrupted, and the hindwings more dark brownish-grey. India, Ceylon, 
Borneo. — heylaertsi nom. nov. ( = bipunctata Heyl.) differs, according to Snellen, from Walker’s bipunctata heylaertsi. 
by the second small dark band of the forewing being straight, not undulate, the form being smaller, too. Batavia, 
Buitenzorg, Tegal, Pengalengan. 
E. similis Rothsch. The $ resembles bipunctata. Antennae light brown; head creamy-white; thorax similis. 
chocolate-violet, base of patagia and the anterior third of the thorax creamy-white; abdomen greyish buff. 
Forewings white, a spot at the base, an antemedian band, 2 large postmedian spots, connected by a very fine 
line on the middle fold, and a marginal band are chocolate-violet, in the marginal band a white spot; hindwing 
dirty buff, in the distal half verv much suffused with grey. Length of forewings: 13 mm. Perak, at an altitude 
of 1800 ft.
