India and is better known under the name coreoides Moore. Probably consimilis Fldr., described as from Java, 
where it does not occur, is also a synonym of coreta. Larva with black head and white labrum, body of 
indefinite colouring, ground-colour blackish with blue dorsal line, some segments with yellowish, others with 
greenish violet sheen. Tentacles indigo-coloured, legs black. Pupa silvery with broad brown bands. Larva 
on the underside of young leaves of Ichnocarpus frutescens, much infested with ichneumons. — montana 
Fldr. is the Ceylon race of the preceding, with melanotic colouring of the forewing, on which above the 
submarginal dots are almost obsolete in the c?cd and much darkened in the ??. Also beneath all the white 
markings are reduced. At certain seasons not rare, montana ascends from the plains up to about 2000 m. 
and is met with at Nuwara Eliya in May; sometimes it accompanies the common asela in its migrations. 
E. harrisi, a continental Indian species with the most wonderful blue reflection, is broken up into two 
geographical races, and on account of itstendency to individual variability a whole series of names has been 
given to single, sometimes very unimportant forms. In spite of its commonness the early stages are still 
unknown. hopei Fldr. resembles the figured binotata (82 a), except that the hindwing bears a row of large 
white submarginal spots. This is the most northerly branch of the collective species, from Assam, Sikkim 
and Cachar, described by Felder. binotata Btlr. (82 a) is the type-form, hindwing without white wedge- 
spots, very common in Sikkim and Assam. Some examples have light blue, white-dotted subapical patches 
on the forewing, moreover the blue discal spots vary considerably in size; sometimes the two rows on the 
forewing are prolonged and joined together. The cell-dot is sometimes suppressed. — pygmaea Moore is 
founded on a ? of the dry-season form, with violet upper surface and an elongate white wedge-spot in the 
cell of the forewing. —- microsticta Bt/r., without exact locality, is probably a cf-form of the rainy season, 
with extraordinarily large wings, and ab. regina Moore is an aberration without white submarginal dots 
on the hindwing and bearing very small white punctiform spots, described from Cachar. — harrisi Fldr. 
extends from Tenasserim to the Malay Peninsula, was described by Feeder from Cochinchina, and collected 
by me in numbers in January in Siam, in February in a very small dry-season form in South Annam, and 
in June and July in Tonkin, ab. crowleyi Moore is a melanotic aberration from Tenasserim, in which the 
two rows of white spots on the hindwing are absent. — depunclata form. nov. are specimens without whitish 
submarginal dots on the forewing, which I have before me from Siam, and ab. discalis form. nov. is a rare 
aberration, with distinct blue cell- and 5 transcellular patches on the forewing, with normal hindwing, which 
bears a double row of white dots, and hence forms a transition to hopei Fldr. from Assam. 
E. lacordairei is the name-type of a series of geographical races distributed over all the Macromalayan 
and some of the Micromalayan islands, which forms a very natural transition from harrisi Fldr. from the 
Indian continent to dufresne Godt. from the Philippines. Whether all the three species now regarded as 
separate belong to one collective species is a question which can only be solved by further anatomical research. 
As in certain species of Salpinx , so also here reliable conclusions as to the specific rank of individual forms 
can scarcely be drawn at present from the only slightly different shape of the valves. — mithrenes subsp. 
nov., from Sumatra, differs from the figured harrisi (84b) in the darker, more steel- than light blue reflection 
on the upper surface and in the unequal and darker blue-violet submarginal spots of the forewing. Hindwing 
nearly always without submarginal rows of white spots, which are only absent on the under surface. On 
the other hand there is always an admarginal row of white dots on the hinclwing and the discal spots on 
the underside of the forewing j&e very distinct, pirina is nowhere common and does not extend beyond the 
alluvial plains and the adjoining spurs of the mountains. ?? are very rare. — convallaria Thierne is a well 
marked race with a row of very large, pure white subapical spots on the forewing, which are only at their 
proximal margin sprinkled with brownish atoms. Hindwing with five or six small white submarginal spots, 
which become smaller posteriorly. Upper surface deep brown, the violet gloss of the forewing is scarcely 
recognizable, and only in certain lights. Distal margin of both wings with the exception of the apical part 
with minute dots, which are placed nearer to the margin than in lacordairei from Java. Nias, only 1 & 
known. — nica Fruhst. differs both from convallaria and pirina in the particularly bright blue gloss even of 
the hindwing, in which it strongly recalls harrisi, except that the reflection is appreciably darker than even 
in Siam examples. Forewing with five very large, light blue submarginal spots without white centres; hindwing 
in the cf with three obsolescent, in the ? with pronounced, small subapical spots. Under surface deep black- 
brown with large whitish blue discal patches on the forewing. Hindwing, however, only with a few and 
nearly obsolete blue cell- and marginal dots. Engano, very rare. Flies in April. — tyrianthina Moore , 
described from North Borneo, in my collection also from South-East Borneo, closely approaches mithrenes 
from Sumatra, but is generally larger, the subapical blue spots of the forewing correspondingly larger, the 
blue gloss somewhat brighter on the forewing, but less bright on the hindwing and the under surface deeper 
brown with the white marginal dots reduced — dotata Fruhst ., from Palawan, forms the transition to dufresne 
Godt. from the Philippines, has a more intensively blue gloss than tyrianthina and always bears, particularly 
in the ?, large, rounded, light violet submarginal patches on the forewing, which traverse the entire wing to
