MYCALESIS. By H. Fruhstorfer 
clots. Whereas I possess nala exclusively from the east of the island where it hardly ever rises more than 1500 
feet above the level of the sea, sudra lives more in the west, never flies below an altitude of 4000 feet and was 
particularly plentiful on the Pengalengan tableland, where it simply swarmed on the weeds in the somewhat 
neglected coffee plantations and together with Ypihima was the only butterfly to be caught on dull days. 
— volsina svibsp. nov. is a smaller race from the east of Java with a more sharply marked pale distal region 
on up. s. and a darker brown marginal border on both wings. It flies on the Tengger mountains at about 
4000 feet. — tannis subsp. nov. from Bali island, where it was captured by the Javanese chasseur of Dr. Martin. 
Insular melanism is clearly expressed by the darkening of the distal region of up. s. of both wings in <$ and 
by the submarginal parts un. s. of both wings in either sex being completely covered with dark brown. The 
yellowish submarginal band of much narrower, though in £ even rather broader than in sudra. 
2) without concave discoidal cell h. w. 
M. maianeas. is after oroatis Hew. the species the most richly provided with secondary sexual characters 
in Macromalayana. The speculum of h. w. very big, costal border strongly concave. Hair pencil whitish, andro- 
conial depression deep, narrow and white scaled. Submargin of f. w. with a black spot above which are yellow¬ 
ish scent scales. Un. s. with a large scaleless bare spot and a sprinkling of white-yellow scales on submarginal. 
Two geographical forms have been described, maianeas Hew. from the Malay peninsula and Borneo, distinguish¬ 
ed by a splendid reddish yellow-oclire subapical band f. w. that is but slightly intimated however in the 
— maia Nicev. (92 f) generally surpasses the Borneo form in both sexes and is characterised by the yellowish 
subapical part of f. w. being considerably darker in both sexes. N. E. and W.-Sumatra, Banka. In forests 
on mountain spurs, not common, is fond of settling on the bare earth. The dainty violet shot dark brown $<$ 
are most delicate creatures and it is scarcely possible to obtain a faultless specimen. 
b. With subapical scent scales on f. w. 
M. nala Fldr. (93 b). This highly interesting Cuktpa is distinguished at a glance from all known Asiatic 
Mycalesis, it bears a deep-blue scent-pencil on the distal between the radial and upper median of f. w. This 
sexual distinction is some 5 mm. broad at upper median, narrows off somewhat and consists of short velvety 
thickly standing scales. On the submarginal is a further sexual characteristic, a short thin tuft of brown hair 
springing from a narrow scaleless, almost flat scent region, a reminder that nala is akin to sudra Fldr. The 
h. w. bears the usual hair pencil at the furcation of the subcostal. This pencil is pale yellow throughout while 
sudra’ s pencil is a deep black at the roots. The f. w. has a remarkably sharp cut, barely rounded apex and is 
more pointed than that of any other Culapa from the Sunda Islands. The antennae are also essentially different, 
being finer and of a pale gray instead of being ringed with yellow like sudra. The palpi and legs of nala are light 
gray, those of sudra brown-yellow. Coloring of up. s. of wings similar to that of sudra but of an even dark Vandyk 
brown ivith a touch of red brown. Un. s. except the sharply defined yellow gray sub marginal region of a deep 
black so that the apical region of the wings seems to be made of velvet. The f. w. has six and the h. w. seven 
small eyespots. The rest as in sudra, save that the marginal zone seems narrowed and sprinkled over with darker 
scales. Strange to say, no closely connected species are known from Borneo and Sumatra, though a nearly 
allied form, anaxoides, is found in Tenasserim and Malacca. West-Java, rather rare. Commoner in the east, 
southward from Malag in the chalk hills up to 500 m and on the spurs of the Tengger range up to about 600 m. 
All the year round but chiefly in March and April. 
Vth. group, h. w. with a subcostal and subbasal hair pencil. 
a. F. w. un. s. without deep androconial cavity. ( Myrtilus Nicev.) 
M. mystes Nicev. Of this rare insect up till now only two $ of the dry and one $ of the rainy season 
form are known. I was fortunate enough to net a $ in Siam belonging to the dry season form which cnly dif¬ 
fers from De Niceville’s fig. of mystes $ in the rounder cut of the wing, a bigger eyespot f. w. and a broader 
median band un. s. — tunicula form. nov. (93 a) Siam, in January at about 500 m altitude. The eyed form 
strongly resembles mara Fruhst. (93 b), but has four instead of one subapical eyespot f. w. un. s. It is not cer¬ 
tain that mystes is not merely a local race of the following species. 
M. satigaica, a Chinese species with an offshoot at Formosa, is still very rarely met with in collections. 
— sangaica Btlr. (Vol I p. 81 fig. 29 b) described from Mongolia is the northern geographical race. — parva 
Leech (Yol. p. 81, fig 29 b) an interesting mountain form, and mara Fruhst. (92 c and 93 b) smaller and darker 
than sangaica, with broader white discal bands on un. s. and bigger eyespots especially in the §. Formosa.
