of the hindwings unnoticeably filled with white. The anterior tail longer than in delphis. $ still unknown; 
the (JU never common, preferring wet places on roads through the woods and on river-crossings, often in 
othonis. the midst of swarms of Pierides and Pap. antiphates. — othonis Fruhst. resembles concha above, but it 
also remains smaller; the black apical margin somewhat narrower. Under surface characterized by a very 
broad greenish-ochreous submarginal band extending distally to the very slender light blue anteterminal 
streaks, appearing thus still broader than in the $ described above from Tenasserim. A $ in the Coll. 
Adams in the British Museum is superior to the in size, and at the same time the yellow band so charac¬ 
teristic of othonis appears as a twice as broad submarginal band, compared to the <£; Island of Nias, very 
cygnus. rare. — cygnus R. and J ., an excellent race the most nearly allied to delphis from Assam by its habitus and 
by the mostly large apical spot of the forewings. Under surface distinguished by the smaller blue circles 
and the indistinct, more greenish than ochreous bands of the hindwings. East and West Java, very rare. The 
$ lying before me in one specimen from the promontory of the Tengger Mountains in East Java, together with 
another $ in the Adams-Collection captured by myself in East Java, form the only specimens known. $ about 
one third larger than the under surface of hindwings with somewhat more distinct, yellowish-green bands. 
delphinion. — delphiniotl Fruhst. is smaller, more intensely yellow than concha, with more blurred black and green sub¬ 
marginal lunae on the upper surface of the hindwings. The tails are shorter, the yellow bands of the under 
niveus. surface darker. North and South Borneo. — niveus R. and J. has a still more receding black apical margin 
than delphinion and beneath narrower, but darker ochreous longitudinal bands of the hindwings. Very rare; 
Island of Palawan. 
E. schreiber numbers among the species being the easiest recognizable by the white median band of 
the upper surface, being richly decorated with blue and replaced on the under surface of the hindwings by 
a band of silvery lustre. The hindwings exhibit besides at the terminal margin a series of ochre-yellow crescents 
being absent in the ^ of some insular races, though existing presumably in all the $$. Larva on Nephelium 
lappaceum L., as well as Rourea santaloides W. and A., and Wagatea spicata Dalz. In Java besides yet on 
Cynometra cauliflora. The full-grown, dark velvety-green larva of about 7 cm length is fusiform, the thickest 
over the central segments, tapering towards head and anus. The likewise green, flattened head appears some¬ 
what broader on account of the horns projecting posteriorly from it and being flat-appressed to the body. These 
horns forming quite respectable antlers are stretched backward in about such a way as we often see it on illu¬ 
strations of a drinking stag or when it troats in the rutting-time; they are backwards and downwards roughly 
dentated, the strongest, brown-coloured tooth standing in the notch between the inner and outer horn of each 
side, but belonging with its base to the inner horn. The two median, frontal horns are straight, whereas the 
two outer, temporal ones appear bent concave inwards. The ends of the otherwise green horns are obtuse and 
coloured brownish yellow. Between the two median, frontal horns there are yet two short black dents likewise 
turned backwards, and before the rising of the temporal horns there are yet at each side of the head three green 
obtuse teeth, increasing in size from the mandible towards the horn. The head with its copious arming would 
form a magnificent, phantastic sight in a miniature collection of larval antlers. The second segment of the body 
is separated from the first one following immediately after the head by a white ring round the neck, thus separa¬ 
ting the body like a decorative neck-band. On the fifth segment, right across the back of the larva, there is 
a finely dotted, brownish-yellow crescent with rounded points concave towards the head; this crescent is bor¬ 
dered by a light greenish-yellow line and a black one following outwardly. The anal segment exhibits above 
the anus a concave excision, so that the last segment forms to the right and left a short tooth which however, 
have not the least connection with the anal spikes of the larvae of the Satyrids, for they are not appendages 
or protuberances, but only a change of form in the last, twelfth segment. The skin of the larva when examined 
under a magnifying glass appears decorated with fine, yellowish dots, similar to the oil-glands of the orange- 
skin. The larva had strongly spun over the upper half of a Rambutan leaf, and on this place it kept its rest 
and digested, from here it visited other leaves of which it ate most irregularly now here, then there from the 
rims, without ever eating hardly half the leaf. The pair of feet of the anal segment, the anal feet, seem to be 
incompletely developed and, when the larva is at rest, they are not used at all, but kept drawn in, so that 
the anal end of the larva stands away from the leaf, but parallel to it, in a similar way as the stern of an 
unloaded steamer lies high above the surface of the water. After three days, the larva grew restless, leaving 
its spun-over resting-place and beginning to run about aimlessly and quickly, so that it had to be put into 
a box where, after a few hours, it suspended itself on a branch of the food-plant for its pupation, turning its 
head quite round to the anus so that it forms a ring, just like the larvae of E. athamas Drury. Disco¬ 
louring into a lighter, dirty greenish tinge, the larva pupated only after 36 hours. The pupa is, like that of 
athamas, of a stout, rounded shape without any protuberances, but is of nearly double the size and coloured 
in a lustrous green with whitish, cloudy shades especially on the proximal margin of the wings, to be com¬ 
pared with hoar-frost or vapour on fruit. On both sides of the ventral segments the mouths of the tracheae 
are indicated by 7 brown, prominent dots reminding us of the chocolate-icing of a confectioner. The entirely
