a narrow stripe as far as the base from which it is yet somewhat remote in pseudoinsularis Fruhst. On the 
hindwing the yellow discal cloud is divided into 2 parts by the ground-colour interrupting it. Likewise from 
the Philippines. —- bazilana Fruhst. $ with a somewhat narrower margin (particularly in the apical part of 
the forewing) as in pseudoinsularis-<$ (162 d); in the $ the wings beneath are only traversed by a faded dark 
line, without any distinct brown transverse bands. Above the discal spots are darker orange; the spot of the 
hindwing is narrower and darkens towards the base. Bazilan. —- jolona Fruhst. (162 c, d). The black costal 
margin is narrower than in the celebensis-g, its width being in the middle between izabella and bazilana. In 
the 2 the ochreous yellowish-red discal spots of the forewing are not so strongly notched by the dark veins, 
in the hindwing the discal spot is flatter and shorter and broader. Island of Jolo. — jopa Fruhst. (162 c 
as gopa) has in the $ a'narrower black margin. Fruhstorfer described the $ as showing yellow discal 
spots, but he hack a 2 figured with white spots above as ,,gopa“-Q. The original description says: ,,$ with 
a uniform, oval, yellowish discal spot of the forewing and a triangular, distally broad, proximally pointed 
median macula of the hindwing which in its size varies between the figures of insularis Dist. and sperthis Dist. u 
From South Borneo. —■ A somewhat smaller form from North East- Borneo is once more separated as minima 
Dist. & Pryer (= nesophila Drc. nec Fldr., aesopus Drc.). But Drttce mentions the remarkable variability 
of this form showing all the transitions between specimens in which only the distal half of the costal margin 
is narrow brown and such in which the costal blackish-brown extends broad to the base. — sperthis Fldr. 
is the form from Malacca, it is according to Fruhstorfer very variable according to the season, the $ showing 
sometimes a broader, sometimes a narrower black margin of the wings; in the $ (on Distaht’s figure) the dull 
ochreous-yellow spot of the forewing extends to the base of the wing, the spot of the hindwing has the position 
of that of jolona (162 d), but in its apical part it is considerably broader. — pseudoinsularis Fruhst. (= insularis 
Dist. nec Horsf.) (162 d) has in the male a very broad black costal and distal margin of the forewing and the 
hindwing intensely covered with brown; in the $ the yellowish-red spot of the forewing is somewhat'like in 
nesophila (162 c), whereas the spot of the hindwing is very much smaller than there, about only the size as its 
apical half. — felderi Dist. From Malacca and Sumatra. probably not to be separated from the preceding, 
9 with very large, light ochreous discal spots. — iildosinica Fruhst. is a small, relatively light race. $ with a 
very broad, black apical margin of the forewing and a very narrow black margin of the hindwing. The $ resem¬ 
bles that of jolona (162 d), but the brown inner-marginal band terminating the discal spot of the forewing beneath, 
is at the base narrowed, whereas in jolona it is broad almost as far as the base. Siam, South Annam, 
taken in February; perhaps also from Hainan, where a ,, sperthis 1 ' is mentioned by Crowley, unless this repre¬ 
sents — as Fruhstorfer presumes — a separate form. —- hera Fruhst. belongs as the rainy season form to 
niasica Fruhst. (162 f). hera is recognizable by the broad greyish-brown transverse bands beneath rhich are 
in niasica replaced by fine, black, several times interrupted transverse lines; the upper surface of the latter 
form is to be seen from our figures where particularly the macula of the hindwing being reduced to a small 
full-moon is distinctly noticeable. Island of Nias. — saronis Mr. (162 f) finally is the form from the Andamans; 
the spot of the $ forewing has the approximate shape of that in insularis -§ (162 b), though it is not quite so 
light; the spot of the hindwing is a curved, rather narrow and somewhat slanting small band. ■—- On the whole, 
it seems as if the forms of this species vary rather much according to the season, and it is probably very 
questionable whether all of them will be maintainable as distinctly separable forms. 
C. bulis Dbl. Hew. Like the thetis-iorms chiefly inhabit the Indian Continent, the insularis parti¬ 
cularly the islands, the Indo-Chinese-Japanese bulis are opposed to the Malayan-Philippine forms of sanatana. 
The bulis have a straight, sometimes even somewhat concave margin of the hindwing from the anal angle to 
the middle of the distal margin, as it is often found in diurnal lepidoptera as a common injury of the wings. 
Nor does the upper surface ever exhibit such a uniformly red area as in most of the forms of thetis. The 
typical bulis conies from the Himalaya, from Nepal, Bhutan, Sylhet, Gori, Kumaon and the adjoining parts 
of North India. with a dull red, $ with a white discal cloud on both wings. — discalis Mr. is the rainy 
season form of bulis, much darker, the central clouds more hazy and less extensive. — dentata Mr. and angu- 
lata Mr. seem to represent the two preceding in the North-Western Himalaya, the former with rounded 
wings as the rainy season form, the latter with angular wings as the dry season form. — stigmata Mr. from 
the Mergui Archipelago, Burma (Tenasserim) is hardly separable from bulis ; the variegated surface of the wings 
is here rather broad; at the transverse vein of the forewing no black tooth. — fortunatus Fruhst. has a 
narrower black anal margin of the hindwing, whereas the distal-marginal part of the forewing is broader black; 
Tonkin, Siam; to the north the species extends across Yunnan to Central China where it reaches the palearctic 
region and passes over into the scarcely separable East Asiatic form acuta Mr. ($ = truncata Mr.) being much 
darker than the allied Japanese form japonica Fruhst. (Vol. I, t. 75c as acuta)\ as to this form and the 
very similar tsushimana Fruhst. and as to the life-history of the species comp. Vol. I, p. 276. — Finally 
another form has been described according to a single $ taken on June 15th near Kanshire in Formosa, 
formosana Fruhst., which is said to approximate the preceding forms, but differs by the broad black distal 
margin and the broader and longer red hue of the hindwing proceeding farther into the anal region. 
C. sanatana Mr. (= phaedrus Hbn. nec F.) (162 g as santana). This species shows again more 
the shape of wings of thetis with which it is also often confounded in collections; some how r ever, distinctly
