C. hageni spec. nov. (10 c). Resembles formicina and the abdomen as in this species with a double row 
ot orange yellow spots, but the transparent spot in the cell of the forewings is much shorter and the hind- 
wings have a very small basal spot, which is not traversed by any of the weins. Captured by B. Hagen in 
April at Stephansort (German New Guinea). Type in my collection. 
C. decorata Wkr. (= florina Butl.) (10 c). Transparent spots much increased in size, between the median 
veins beneath the cell a further spot is present; the apical forewing spot and the anal hindwing spot are 
yellow, the others slightly tinged with yellow. Thorax with yellow longitudinal stripes, abdomen yellow, 
slightly banded with brown. Borneo, discovered by A. R. Wallace. 
C. flavibasis limps. (10 d). The transparent spots are coalesced to a large transparent area, only the 
borders of the wings, a bridge from the discocellular to the outer margin and a tooth like mark at the end 
of the median nervure are dark brown. Abdomen brown, finely ringed with yellow. Malacca, Sumatra; 
discovered by E. Hartert. 
C. fata Swinh. (10 d). Almost like a small decorata, but the apical spots of the forewings are not yellow, 
the forewing apex itself is broader black. From Borneo; type in the Oxford Museum. 
C. exapta Swinh. (lOd). Very like the former, but with a broader blackish brown margin (outer) to 
the forewings, owing to the transparent spots beyond the end of the cell not reaching so near to the outer 
margin. Sumbawa, Flores, Lombok. 
C. claremonti Heyl. (10 d). All the transparent forewing spots reach to the outer margin; which only 
remains slightly darker; on the other hand the base of the forewings is broad blackish brown. Hindwings in 
the cf entirely, in the ? mostly transparent with the exception of a narrow dark costal border. Sumatra and Java. 
C. cherra Moore (= quisqualls Swinh.) (lOd). Has almost the appearance of Syntomis germana, (Vol. 2, 
pi. 9 g) but besides the wingshape can immediately be recognized by the more extended transparent spots and 
the more graceful build, abdomen ringed with golden yellow. Khasia Hills, type in the Staudinger collection 
in the Zool. Museum in Berlin. 
C. chea Druce (10 d). One of the largest species, which in general appearance somewhat resembles 
Syntomis fortunei. As in the latter the spot under the middle of the forewing cell is aslant. The hindwings 
have either only one small white spot just above the anal border, as in the specimen figured (caught in 
Sibulan in January) or sometimes a second just beyond the middle. The abdomen has a yellow ring on the 
4 lh segment, but which is interrupted along the side of the back and beneath. Philippines, Mindanao dis¬ 
covered by Semper. 
C. imaon Cr. (= fusiformis Wkr., approximata Wkr.,) (10 e). The species is figured Vol. 2, pi. 9h and 
discussed on p. 41. In the form sargania which was described from Cachar, only a very small spot is present 
between the costal and terminal groups of spots, which can be wanting in Ceylon specimens of which we 
figure a ¥; — in arlina Butl. from Calcutta the transparent spot of the hindwings is enlarged, — in mota 
Swinh. reduced to its lower portion. The species is extremely widely distributed and extends from Hong-Kong 
through the whole of South China, hither India, Hindustan to Cashmir, where it reaches palaearctic territory. 
I found them at Kandy in Ceylon locally in April, but occasionally not rare and met with them singly in the 
Nilghirry Hills from lvollar to Coonoor. 
C. expandens Wkr. (lOe). Body and basal third of all wings blackish brown; the three median trans¬ 
parent spots of the forewings are arranged to form abroad transverse band; the transparent spot of the hind¬ 
wings is placed in the outer half of the wing, or the hindwings are nostly hyaline and have only dark borders 
(= ab. inaequalis Snell, discovered by B. Hagen on Sumatra Deli); Malacca Borneo. — In ericsonni Bothsch. 
(10 e) from Padang Sidempuan (West Sumatra) the hyaline transverse band composed of the three middle spots 
is sharply defined, whereas in typical expandens the central spot is produced more outwards, and the hindwing 
spot enlarged. 
C. aroa Beth.-Baker. ? Head and thorax black, petagia and metathorax spotted with orange, abdomen 
brownish black, with a subdorsal and ventral row of orange spots. Forewings above pale brown. Forewings 
with a long pearshaped transparent spot in the cell, a larger spot under the cell, broadened in the middle 
and with a rounded end, beneath this a narrow transparent streak, a small spot in the angle of 2 and 3, a 
longish spot above 3 and 4, a long drawn out one above 6 and a short one above 7. Hindwings with a 
transparent spot below vein 2 and a further one between 2 and 5. Base of the wings slightly tinged with 
yellow, 28—33 mm. Upper Aroa river. 
C. swinhoei Beth.-Baker. Head, antennae, thorax and abdomen black, patagia with a single yellow 
spot. Wings blackish brown; forewings with a long clubbed spot in the cell and a more extended one 
beneath it. A long spot between 3 and 4, a longer above 6 and a short one above 7. Hindwings with a 
transparent spot beneath 2 and small one beneath 5. New Guinea.
