distinct, on the hindwing the white discal band is considerably narrower and equally much contracted as in 
bajadeta, whilst in martini its width hardly changes. The discal border on the upper surface of the hindwing 
differs from bajadeta in its being contracted from the lower radial onwards making room for a yellow-red 
submarginal band, whereas in the specimens from Java its width is the same as far as the anal angle. In 
bajadetina the submarginal lunular spots are less conspicuous and confluent than in the Javanese forms. 
From western Sumatra. — bajadeta Moore, found in Java, represents a quite distinct insular race, cf is of 
smaller size than in the hitherto enumerated forms, the underside more variegated, with more prominent white 
fasciae on the hindwing. In the ? the upper surface of both wings has the black marginal area much farther 
extended, whereby the submarginal zone of the forewing becomes considerably narrower. Under surface more 
brightly coloured than is the case even with the specimens from Borneo, with the yellowish antemarginal lines 
narrower, cd very common, ? rather scarce, in eastern and western Java at elevations up to 2200 ft. - 
ravana Moore. ? is distinguished from emalea and bajadetina by the increased black colouring and in having 
the under surface more richly shaded with red-brown. My coll, contains specimens from North- and South- 
East-Borneo, where they apparently are not rare. —- lapaona Klieil. (?-lunulata Kheil.). This local race which 
deviates more than any other from the typical form, is smaller in size, the forewings are more rounded, the 
upper surface paler yellow, the under surface of a light orange colour with a constricted white median band. 
? quite similar to the a 71 , can be distinguished only by the undulate anteterminal bands on the forewings which 
are of a more pronounced yellow colour, and by the fact that on the under surface the distal half of the 
hindwings is more richly decorated with white. Abundant in the island of Nias. 
C. malaya. This species is, together with its local races, regarded by some authors as a dry-season 
form of C. emalea. Both have indeed much in common, as regards the general design, the distribution of the 
black spots in the median area of the hindwings and the submarginal spots in the apical portion of the 
forewings beneath. On the other hand malaya differs essentially in the absence of the yellow patch before 
the apex and more still in the complete want of black scales upon the veins on the upper surface of the 
forewings. On the under surface of the forewing the discal band increases but slightly as it approaches the 
costa, while on the hindwing the median band remains unchanged from costa to the anal angle showing no 
contraction whatsoever. Also the sexual organs are different. Uncus weak, pointed, not curved distally. Valve 
smaller and shorter, with dorsally incurved appendage. The species occurs throughout the Macromalayan 
Archipelago, with the exception of Java. — malaya Fldr. is of all the forms the palest in colour; the hind¬ 
wings with delicate black marginal lines and median spots. On the forewings there appear, owing to the 
narrow bordering, upon the fifth subcostal and the upper radial several distinct sexual stripes, composed of 
short streaks of modified scales of a yellow colour; they disappear in the Borneo-form but are still retained 
in naiuna Fruhst. From Perak and north-eastern Sumatra. ? not known; the specimen figured by Distant 
(PI. 10 f, 3) as ? is the rainy-season form of malaya, to which the name johannes Btlr. may be applied. — 
naiuna Fruhst. This form differs from malaya (received from Singapore and other localities) in having the 
forewings less broadly bordered with black, and in the greater extent of the yellow colour in the subcostal 
region which causes the black spot before the apex to appear isolated, whereas in malaya it touches the 
black costal border. The discal spots on the hindwing are twice as large as in malaya and calypso Wall. 
from Borneo. The ground-colour of both wings is a pale yellow. From the Natuna Islands. - calypso Wall. 
(108 b) follows the general rule according to which, among the Macromalayan forms, the race from Borneo 
appears darkest. In calypso the black distal border on both wings is nearly twice as broad as in malaya and 
natuna; the submarginal fasciae on hindwing are much farther extended; the white discal bands on the under 
surface become broader, and there appear in the apical area some white spots recalling by their large size 
the subapical spots found in bajadeta Moore. In the ?? the black terminal border is more pronounced than 
in the c I'd 1 ; besides, they have broad submarginal bands of a glossy straw-yellow separated from the dark 
brown basal half by a sharply-defined discal band of black-brown. The ? of calypso resembles ? of ravana 
Moore, but the wings are more rounded, the discal bands on the under side are not such a clear white and 
form a straighter line. Occurs in North-Borneo, in the low-lands. — baluna Fruhst. is the form peculiar to 
the mountains and the rainy-season. The ? differs from that of calypso in having a still broader black marginal 
border on both wings, whereby the yellowish submarginal zone becomes even more reduced. The under surface 
is reddish instead of gray-white, with the longitudinal band much narrower but of a purer white. From Kina-Balu. 
C. satellita is distributed all over the Macromalayan Archipelago, with the exception of Java, reaching 
Palawan in the north. Under surface a lovely bright yellow growing darker towards the margin. Both wings 
are traversed by a broad white band which is bordered on either side with red, turning straw-coloured 
toward the costa in the forewings. The hindwings contain also a row of black spots, as is usual in Cirro- 
chroa, but less complete. There are two local forms known: satellita Btlr. erroneously described as coming 
from ‘Hongkong’; it is confined to the Malay Peninsula and the north-eastern portion of Sumatra, where it 
apparently occurs only within narrow limits; several large collections I received from western Sumatra did 
not contain it. Its flight is weak, its chief haunts are the wooded parts of the plains. The yellow belt on 
the forewing is curving outward near the anal border. — illergeta subsp. nov. (108 b figured under the name of
