is distinguished by the distal half of the forewing in cf and ? being for the most part reddish purple, and 
only proximally pure black. The frons of the ? is very narrow and the blue submarginal band of the 
hindwing beneath is also wanting in the only ? known to me. I pair in the Tring Museum. 
E. (?) dichroa spec. nov. ?: so similar to circumdata as to be easily mistaken for it. All the legs dichroa. 
on the underside yellow-grey. Frons much broader and only slightly projecting. Antenna with much longer 
pectinations from the base. In the hindwing only 2 radial veins, the 2. and 3. anastomosed, the median veins 
more distal than in circumdata. Base of the forewing somewhat more broadly black, the yellow area distallv 
more symmetrically rounded, the distal area black, the marginal band not extending so far posteriorly as in 
circumdata; no green-blue submarginal band on the under surface. — Khasia Hills, Assam; 1 ? in the British Museum. 
E. risa Doubt. (6 c). Body and wings of the cf above unicolorous green-black, or forewing with risa. 
remnant of a yellow band, collar narrowly red; under surface similar to that of the ?, but the yellow parts 
paler. 2 with yellow band before the middle of the forewing and yellow hindwing, the extreme base of 
the latter and the distal margin black; beneath more or less blue on the veins, a narrow grey-yellow band 
before the distal margin. Abdomen beneath with white margins to the segments. — Larva on Symplocos 
and Thea, brown, later brownish orange-yellow or red, with blackish longitudinal lines; when it is touched 
drops of a clear scentless fluid exude from the tubercles. — Borneo; Natuna Islands; Malacca; Java. 
E. angustipennis Rob. (6 c) ?. Confusingly similar to the preceding species. Abdomen beneath with angusti- 
blue margins to the segments; the last abdominal segment above blue only at the tip, otherwise yellow like pennis. 
the preceding segments; genital aperture on a cone, which is situated in a depression surrounded posteriorly 
and laterally by a thick chitinous wall. Forewing beneath with blue submarginal line; the black distal 
margin of the hindwing narrower than in E. visa. cf not known. — Java; Sumatra; North Borneo. 
E. circinata H.-Sch. (— fasciata Walk.) (6c). cf and $ alike: body blue or green, thorax black, circinata. 
Wings black, beneath the base of the forewing and 2 / 3 of the hindwing blue; forewing with pale yellow band; 
hindwing with deep yellow marginal area, which has a row of black spots. — North India: Sikkim, Assam. 
E. repleta Walk. Body above blue-green, beneath green. Forewing above olive-green, with pale 
yellow band, which is acconpanied by black spots and intersected by blue veins. Hindwing black, blue 
from the cell to the hindmargin and at the distal margin; above either without yellow markings: ab. urania urania.

Walk. (— submarginalis Swinh.). Beneath a blue or whitish blue band before the distal margin. — North repleta. 
India; Burma; Cambodja. The name-type of repleta Walk., a cf from Cambodja, is in the Oxford Museum, 
and was redescribed by Swinhoe. 
E. rajah Moore (6d). Head, thorax and upper surface of the wings dull green, abdomen and hind- rajah. 
margin of the hindwing dull blue-green; underside of the body yellow; collar red. Forewing with a yellow 
band; hindwing orange-yellow, veins black. Beneath the forewing also yellow at the tip, blue in the basal half; 
veins of the hindwing blue. — North India: Sikkim, Assam; one of the most beautiful species of the Zygaenids. 
E. subcyanea Walk. (= coelestina Auriv.) (6d). Thorax green-black, abdomen blue. Forewin g subcyanea. 
above green-black, a basal band, an interrupted band before the middle, a dot at the apex of the cell and 
a row of oblong dots before the distal margin yellowish white, in the cf all these markings smaller than in 
the ?. Hindwing from the cell to the hindmargin glossy blue, beneath, sometimes also above, in the $ with 
indication of a white band before the middle. — Mt. Gede, Java, 4000 ft. Walker erroneously gave 
Borneo as habitat, the name-type (in the British Museum) came from Java; the frons is rubbed, and 
therefore rust-colour (see Walker’s description). 
E. tricolor Hope (= trimacula Moschl .) (vol.'ll, 2b). Abdomen of the cf above green-black, with tricolor. 
thin yellow bands, beneath yellow; in the ? above yellow, 1. segment black, beneath black with yellow 
margins to the segments. Forewing black-green, spotted with white; hindwing with broad yellow area, 
which extends from the hindmargin to the costa and in the cf is intersected by black veins. — Larva 
brown, without black longitudinal lines. — Sikkim, Bhutan, Assam, Burma, 3—6000 ft. 
E. sublutea Walk. (— scintillans H.-Sch.) (6d). Confusingly similar to the preceding species; the sublutea. 
spots on the breast much larger, the pectinations of the antenna (cf) longer, in the forewing the basal spot 
smaller, sometimes absent, the median spots larger, the spot at the end of the cell smaller; hindwing somewhat 
deeper yellow; beneath a white streak at the costal margin of the forewing at the base and before the median 
spots, the costal margin of the hindwing likewise white before the yellow area and at the base. Anal 
claspers (of the cf) produced into a sharp point, whilst the end of the clasper in tricolor is only bluntly 
pointed; the two spiny processes of the 10. segment long, evenly curved downwards, much longer and also 
narrower than in tricolor, the protuberances at the sides of the penis-sheath large. — North India: Sikkim, Assam. 
E. lativitta Moore (= fasciata Mdschl.) (6e). Abdomen in the cf above blue-black, in the ? yellow; lativitta.
