64 CERYX. By Dr. A. Seitz. 
C. diptera F. (= atereus Stoll., incipiens Wkr.) (9 f). The smallest species, recognizable from the 
fact, that the hindwing is reduced to a small scale. Forewing spots hyaline. Abdomen bluish black with 
yellow rings at the base and on the fifth segment. In typical specimens the basal spot of the forewings and 
the large square spot in the first median space are seperated by a black bridge; — in the form brachypecten 
limps, they are coalesced. In Southern India and Ceylon. 
C. ginorea Sivinli. (10b). Black, with a yellow ring at the base of the abdomen, the forewing spots 
quite transparent, that beneath the end of the cell large,. constricted towards the base. Hindwings with only 
one small transparent spott below the branching of the median vein. Much larger than the former. From 
the Khasia Hills. 
C. keiensis Rothsch. (10 b). Deep blackish brown, in the sun with a strong blue sheen. Metathorax in 
the cf, head and thorax in the ? bright yellow; similar spots at the side of the abdomen. Forewing spots 
hyaline. The cf possesses a most extraordinary character (the ? is not before me) in a thickening of the front 
and meddle tibia to thick clubs; the coxae are also lengthened and increased in size by thick closely lying 
hairs. Key islands in January discovered by 11. Kuhn. 
C. formicina Swinh. (10b). Almost exactly like the foremer, but the front legs of the cd are only 
thickened on the tibia and tarsi through thick hairs. Spotting like the former, but all the hyaline spots are 
larger; that between the median and the submedian almost reaches the outer margine above the anal angle. 
The hindwings are quite transparent with a narrow black border. From New Guinea (Kapaur). 
C. subformicina Beth. Baker, cd forehead yellow, occiput black; collar yellow back; patagia yellow, 
metathorax yellow, abdomen black with yellow segmental divisions. .Forewings above black, the transparent 
spots as follows; a long one in the cell; beneath it one extending to the outer margin, beneath this again 
above the anal angle a small transparent streak, above veins 3 and 4 a long drawn out glass spot, above six 
a further long one and above 7 a small one. Hindwings pale lemon yellow at the base and in the cell; two 
transparent spots beneath the cell, which are divided by vein 2. 31—33 mm. Upper Aroa river; type in the 
Tring Museum. — ? resembles the cd, but in the angle above vein 2 there is a further glass spot. 
C. evar Pay. (= gracilis var. lugens Rob.) (10 b). The transparent spots arranged as in formicina , but 
smaller, the whole apical portion of the hindwings black; thorax and abdomen with yellow spots along the 
side, but weaker than in formicina. From the Key and Am Islands in February and on Amboina. 
C. guttulosa Wkr. (= melanora Meyr.) (10 c). Hindwing spots as in the former species, but the trans¬ 
parent spots in the hindwings are still smaller, only reaching from the anal border to about the middle of 
the wings. Forehead, shoulders and a spot on the matathorax orange yellow, Aru and Key Islands as well 
as Queensland. 
C. affinis Rothsch. (1 0b). Forewings as in the former, but the pro- and metathorax spotted with orange 
red. Further two rows of beautiful orange red spots along the abdomen, which are only divided by a very 
narrow line. From the Kumasi river in Britsh New Guinea discovered by Meek in September. Type Tring Museum. 
C. sphenodes Meyr. (10 c). Head, shoulder plates and metathorax orange red, the abdomen also bright 
orange red. The segmental divisions form fine black rings, which broaden on the back of the abdomen, but 
do not break up the orange rings into spots by coalescing. North east Australia and New Guinea. Type 
in the University in Sydney. 
C. meeki Rothsch. (10 c). Differs from sphenodes on account of the complete orange collar, the almost 
entirely orange abdomen, which is only divided by very fine black segmental divisions and the basal spot of 
the hindwings being yellow instead of transparent. Milne Bay (New Guinea from November to January; 
discovered by A. M. Meek; type in the Tring Museum. 
C. puncta Druce (10 c). The transparent spots in the forewings are larger than in the former, but the 
thorax and abdomen darker, only sligthly spotted with yellow. The yellow hindwing spot is placed as a small 
yellow oval above the base. Humboldt Bay (New Guinea), discovered by Doherty; type in the Druce collection. 
C. ampla Wkr. (10c). All the transparent spots much increased and the whole wings broader; on 
the hindwings besides the yellow tinged spot above the base there is another transparent spot beyond the 
middle. Abdomen yelk yellow marked with brown. Aru Islands, discovered by Wallace. 
C. aurantiobasis Rothsch. (10 c). The submedian spot further seperated by black from the spots between 
the radial veins; in the same manner the yellow basal spot of the hindwings is more widely divided by black 
from the transparent spot beyond the middle; abdomen black with lateral rows of distinct yellow spots. Dutch 
New Guinea (Kapaur), caught in January.
