a melanotic extreme of ribbei. From Choiseul (Solomon Islands). Type in the Fruhstoreer collection, 
necopinata subsp. nov. lacks, like ribbei, the apical spots on the upper surface of the forewings, following also necopinata. 
on the under surface ribbei rather than praesignis, in the well developed marginal spots on the forewings and the 
clearer white basal spotting. Upper surface with a peculiar rudimentary submarginal band, which, although 
resembling that of ribbei, hardly is one third as wide as the median band of ribbei. Hindwings with a pale 
greenish-yellow, complete longitudinal band, rather narrower than the name-type from Bougainville. Of neco¬ 
pinata I possess two <$<$ from the Solomon Islands, locality not given. All three forms of ribbei differ from the 
forms of australis by the presence of a long band on the upper surface of the hindwings, in the presence 
of a broad area in P. australis. The under surface has in the anal angle of the hindwings between the 
internal vein and the lower median a closed lunule, whereas all the forms of australis display there two paral¬ 
lel lines; these lines continue in P. mulderi and dohertyi from the Moluccas as far as the costal margin, whe¬ 
reas in the Papuan australis at least the intramedian striae are united to lunules. 
Group B: Agatasa Moore. 
P. calydonia, undisputedly the most beautiful of all diurnal butterflies of Tropical Asia, was disco¬ 
vered in the Malay Peninsula by Wallace, who wrote as follows upon his find: “One afternoon, when strolling 
along my favorite trail through the woods, with my rifle in the hand, I saw a certain butterfly sitting on the 
ground; it was good-sized, beautiful and cpiite new to me; but on my approach it flew away. Later I dis¬ 
covered that it had been sitting on the ordure of some carnivorous animal. Hoping that it would return 
again, I took on the following morning after breakfast my net, carefully approached the spot and was de¬ 
lighted to find the same butterfly on the same bit of excrement, and I succeded in catching it”. Wallace 
never saw another specimen of this species, and it was not until 12 years after, that another $ came from 
Northwest-Borneo to England. — calydonia Hew., the name-type, has on the forewings the apical spots calydonia. 
somewhat smaller than appears in our figure of the <§. Under surface easy to recognize by the, for an Asiatic 
butterfly quite unique, combination of wine-red, black, chrome-yellow and greenish spots and bands; in this 
form the black median spots^distinguishing the hinclwing are most pronounced. — mahasthama subsp. nov. mahastha- 
inhabits Borneo, whence I possess specimens both from the North and the South-East. Of smaller size than ma ' 
calydonia ; the hindwings with the black distal margin very much narrower, especially in the specimen 
from the south-eastern part of the island. — auricinia subsp. nov. (120 d as calydonia) surpasses calydonia auricinia. 
both in beauty and size; having the pale yellow preapical spots on the forewings larger, but the black border 
of the hindwings narrower; under surface less conspicuously dotted with black in the median area than in 
the Perak type, the red distal border paler, the yellow subbasal band of a clearer shade than in either 
calydonia or mahasthama. Type from the western part of the island, from near Padang-Pandjang; 7 spe¬ 
cimens in the Fruhstorfer collection. Was taken as a great rarity also in Northeast-Sumatra. Dr. Hagen 
discovered in May 1905 a similar form also on the island of Banka. — belisania Croud., an interesting form belisama. 
having, in contradistinction to the broad-bordered calydonia, altogether the appearance of belonging to a 
region with dry climate, which indeed it does. Hindwings with very narrow border, underside of the fore wings 
paler yellow, on the hindwings the black spots less conspicuous, the terminal border wider and paler yellow. 
Discovered by Doherty near Petichaung at the foot of the Karen Hills, not far from Toungo in Tenasserim; 
flies from March till April. Later on several CS were captured by Hauxwell, a forester, in March, April and 
June, by means of a very high scaffolding of bamboo, from the top of which he was able to reach the but¬ 
terflies that were flying to and from between three huge forest-trees. 
P. chrysodonia Stgr. is a distinct representative of calydonia in south-eastern Mindanao where chrysodonia. 
it was first discovered by Dr. Platen. In size inferior to the Macromalayan calydonia, the forewings more richly 
and delicately dotted with yellow. The hindwings lack the leaden grey proximal shading of the much frayed 
terminal border. Underside of the forewings very much the same as in mahasthama Fruhst. from Borneo, 
but with the black spots on the anal margin of the forewing even less marked. On the hindwings the black 
spots more prominent, the submarginal spots reddish instead of green, narrower, more rounded proximally. 
-—- heterodonia Semp. stands intermediate between chrysodonia and calydonia. The black outer border of the heterodonia. 
hindwings broader than in the Mindanao type. But according to Semper the hindwings lack underneath the 
brown-red spots. Mindoro; very scarce. $ not known as yet.
