margins of the wings, whereas the blue reflection in many Sumatran specimens hardly extends beyond the 
centre of the wing. — battakana Fruhst. is an alpine form of sumatranus, flying on the Battak Mts., being larger, 
with a more intense blue lustre on the hindwing. In nola Fruhst., from Borneo, the $ hindwing is more lustrous 
violettish-blue than light blue; the blue colour is more extensive, and the under surface exhibits much more 
prominent black and smaller blue spots than the other races. — rufotaenia Fruhst. (= moorei var. Dist.) was 
described by Frithstorfer as a separate species, but it may also be only a very small form of moorei exhibiting 
a small narrow red band in the anal portion of the hindwing beneath; it may also belong to niasica Rbr. I only 
know Distant’s figure according to an insect in Staitdinger’s collection from Malacca. I have not found 
the species in Singapore, where I was collecting most eagerly. 
M. similis Drc. This Borneo form is said to differ from moorei Dist. only in the subcostal vein being 
four-branched instead of three-branched, and in the more convex distal margin. 
M. ravindra flies in different iskdhls of the Malay Archipelago, and its great resemblance to moorei 
and B. thesmia has given rise to various mistakes. The genuine ravindra is common in Java. According to 
Frithstorfer, the East-Javanese specimens, which he denominates rnedullia (159 g), differ from the West- 
Javanese (ravindra Hsj.) in the great reduction of the blue gloss which in the $ of ravindra occupies the whole 
hindwing. But Piepers who probably had more material at hand from Java, declares these differences to be 
individual and independent from the locality. — balina Fruhst. (159 g) seems also to be founded upon such a 
form with a more reduced and duller blue on the upper surface of the S hindwing; — whereas joloana Stgr. (159 g), 
from Jolo, shows a great reduction of the brown irroration on the forewing beneath. — surindra Drc. (156 g, h) 
comes from the Kina Balu in North Borneo. The blue on the <$ hindwing above is somewhat darker, extends 
to the apex and close along the subcostal vein to the scent-spot; on the under surface the stripe behind the cell- 
end is linear in its whole length and not expanded at the cell-end, as in Javanese ravindra. —- In albula Drc., 
from Sandakan, which according to Druce represents a variation, according to Frithstorfer another Borneo 
race, the ground-colour of the forewing beneath is all white. — The young larva of ravindra is light greyish- 
green or pink, the adult larva mostly brown with a rhomb if or m spot on the centre of the dorsum. It lives on 
Eugenia densiflora and changes into a shoe-shaped brown pupa with belt-threads, yielding the imago after 
10 or 11 days. 
M. ravindrina Stgr. (159 g) would be certainly regarded as the representative of ravindra. in the Jolo Is., 
if the ravindra-iovm joloana (156 g) would not occur there independently from it. From the latter we 
distinguish ravindrina at once by the orange under surface of the forewing. Also the blue of the $ hindwing 
is in ravindrina distinctly tinted violet. Nevertheless it may be a season-form of ravindra. 
M. estella Hew. (159 f). This species occurs in Borneo; <$ above uni-coloured blackish-brown, $ with a 
white anal half of the hindwing. Still more remarkable is the difference beneath, where the transverse bands 
are broken up into spots being scattered on the rosy yellowish-brown ground. — Also found in Sumatra. 
68. Genus : Zeltus Nic. 
Like the preceding genera, this genus is also allied to the Hypolycaena ; in the $ all the margins of the 
forewing are more convex, the whole wing is therefore more rounded off, in the $ the costa and distal margin 
are also more convex, the hindwing is longer and narrower, the tails are more delicate *) with longer fringes, 
the middle one is very long. The body is much more delicate than in Hypolycaena, the flight therefore slower 
and weaker, so that the live insect makes an impression quite different from the individuals of a genus. 
Z. etolus F. (= amasa Hew.) (146 g). $ above blackish, the wings in the distal portion with a blue 
reflection. The whole anal half of the hindwing and the tails are of a very delicate satiny white. $ above 
dark brown, in the anal portion of the hindwing 2 rows of white spots. Easily recognizable beneath, where 
a lustrous satiny white proximal portion with a slight bluish reflection is opposed to a rust-coloured distal part 
on both wings. In specimens of the dry season the brownish-yellow distal portion of the wings is reduced, in 
which the basal white proceeds farther towards the margin. India, from the Himalaya to the Nilgiri Mts. and 
to the east as far as Bmina. — In maximinianus Fruhst., from Malacca, Sumatra and Borneo, the $ forewing 
above is grey, powdered with dark, without a more intense blue gloss. — In gratidianu.s Fruhst. (158 f), from 
Nias the reddish-yellow colour beneath is darker, more distinctly defined, and in the forewing more extensive, 
projecting towards the base beyond the cell-end. ponipaedius Fruhst. In the <$ the white anal portion of 
the hindwing is smaller, because the costal black proceeds farther towards the hind-margin; in the $ the 
white spots in the anal portion are larger. Java. — censorinus Fruhst. is larger than the Javanese race, the 
blue colouring is paler, the subanal black dotting on the hindwing above more reduced. Sumbawa. 
The larva is said to be green, finely haired, with black and red markings. Pupa yellowish-green with an emerald- 
The extraordinary fineness of the small tails which are constantly fluttering in the resting insect even when 
there is apparently no wind stirring, is very well noticeable in our figure of etolus (146 g).
