flying in January and February at about 300 m. According to my observations the butterflies flew there 
only in the afternoon and for a short time, and presented a weird appearance with their colours flashing out just 
momentarily. — sylvarum Fruhst. (94b) is a smaller form with more compact wings and with darker blue re- sylvarum. 
flection extending further on towards the distal border, under surface darker with broader brown longitudinal 
bands on both wings and large anal ocellus, which is anteriorly accompanied by a much smaller eye-spot. Tonkin, 
Chiem Hoa, taken in August and September at the same elevations as nothis. — adamsoni Moore represents adamsoni. 
nothis in Upper Burma, where it was discovered as a great rarity by Major Adamson in September—October 
in the dense, dark, damp Rotang forests. Judging from Moore’s figure it appears to be somewhat smaller 
even than sylvarum, and to differ from the latter on the under surface in having two well developed subanal 
ocelli of equal size on the hindwing. Moreover the distal area of the hindwing beneath is more extended whitish 
grey, with straight, narrow median band. 
C. epiminthia has the upper surface of both wings glossy violet-blue and bears on the hindwing near 
the anal angle above the submedian a strong hair-pencil, which shades a dark steel-blue, oval, posteriorly point¬ 
ed scent-spot. — epiminthia Westw. (94 a) inhabits Macromalayana with the exception of Java and appears epiminthia. 
not to differ locally. CS Rom West Sumatra are somewhat larger than those from North Sumatra, Perak and 
South-East Borneo in my collection. — binghami Moore is only known as yet from Tenasserim, where it probably binghami. 
occurs in two generations, as it was observed in May and then again in October; it is very rare and inhabits 
dense Rotang jungle. It is easy to distinguish from the insular race by the brilliant light blue colouring of the 
upper surface and the row of smaller ocelli on the underside of both wings, which is altogether lighter. Forewing 
in addition with the apical part less strongly produced. — vicinus Fldr. is the very rare Celeban branch vicinus. 
of the collective species, which is unknown to me in nature, and appears to be confined to the north of the is¬ 
land, as neither Doherty nor my collectors found it in the south. 
C. euptychioides occurs in two geographical branches, as euptychioides Fldr. (94 b) in Borneo and as euptychioi- 
humilis Btlr. in Perak and Sumatra. Above the two races differ in the absence in humilis of the delicate blue f es - 
hurm Its 
subanal colouring which distinguishes euptychioides. Under surface of the two almost alike, with an apical 
ocellus on the forewing and four small eye-spots and one large one on the hindwing. The large anal eye-spot 
has a light yellow, strikingly broad border and a white pupil. Both forms are extremely rare. Larva of all the 
species of Coelites probably on Rotang. 
34. Genus: Ptycliamlrst Fldr. 
This genus is called by Schatz an aberrant form of the Lethe group of Satyrids, with the characters 
maintained more in the $, whilst the $ is said rather to recall Lycaenids in the brilliant blue colouring of the 
wings. It seems to me that on account of the three swollen veins of the forewing, which do not occur in Lethe, 
and the sexual characters of the forewing, Ptychandra should much rather be placed near to Mycalesis than to 
Lethe, as it has only the tail-appendages of the hindwing in common with the latter. Ptychandra males differ 
both from Mycalesis and Lethe in having the three median branches arising from one point of the median 
vein, a formation which is nowhere else repeated in the Satyrids. Forewing between the 2. and 3. median branch 
with a deep, elliptical androconia-cavity which is shaded by a long black hair-pencil and sends off an inter- 
neural furrow to the middle of the wing. Anal margin of the forewing beneath ornamented with dull, light 
red-brown scent-scales, with which a narrow costal area filled with dark brown specialized scales corresponds 
on the hindwing above. The upper discocellular of the hindwing is absent; the middle is distally somewhat 
incurved; the lower very long and slightly concave or straight and closing the cell off short. Only three sharply 
differentiated species of the genus are yet known, which again break up into easily recognizable island races. 
— Concerning the earlier stages and the habits of the butterflies nothing lias yet been published. 
A. Forewing with the lower discocellular somewhat curved distally. Androconia-cavity with deep black scales. 
Forewing only with short, stiff hair-pencil below the third median vein. Cell of the hindwing with long, thin hair-pencil. 
P. schadenbergi Semp. £ above dark blue. Forewing with a white crescent at the costal and a white schaden- 
submarginal line. Under surface of both wings grey-black with red-brown undulate bands, forewing with three l)er W l - 
distal ocelli, of which the posterior ones are very indistinct. Hindwing with a row of six almost contiguous 
eye-spots, and a more proximally placed apical eye-spot, which is margined with reddish yellow. There are 
two forms of the $, one which Semper figures, with white anal area on the forewing and yellowish distal region 
on the hindwing, which is only quite narrowly margined with black-brown, probably belonging to the dry-season 
form and hebetatrix Fruhst. (93 g), probably flying in the rainy season, and differing in the grey-brown inner hebetatrix. 
margin of the forewing and the extended brown bordering of the hindwing. On the under surface all the white 
areas of the upperside are reproduced and also the disc of the hindwing is broadly pure white. By this white 
disc and the smaller eye-spots the $ of schadenbergi is easy to distinguish from that of lorquini. Flies according 
to Semper in October, December and January. Mindanao, occurring throughout this large island.
