B. Porewing with the lower discocellular straight and a short hair-pencil between the 1st and 2nd median veins. 
P. lorquini occurs together with schadenbergi on Mindanao and is further distributed over the greater 
part of the Philippines and even the North Moluccas. above very similar to bazilana (93 g), but in the narne- 
lorquini. type lorquini Fldr., from Luzon, somewhat darker blue with more distinct, white subapical spots and somewhat 
broader white submarginal line. As in schadenbergi there are several forms of the $; the typical form is larger 
than that of schadenbergi. Forewing with pure white, broader subapical band but much narrower median one. 
The two are connected, whilst in schadenbergi they are placed far apart; between the upper and middle median 
there is a white circle, which is wanting in schadenbergi. Hindwing: the basal and median areas yellowish instead 
of white. The white colour which in schadenbergi fills up almost the whole discal part of the wing has disappeared 
except for a few submarginal remnants, and is displaced to near the distal margin. Ocelli larger, ringed with 
lighter yellow. Under surface: as on the upper surface, the white .markings of the forewing show a tendency 
obscurior. to increase, those of the hindwing to decrease. Bordering of the ocelli lighter yellow. — obscurior Fruhst. shows 
mindornna. the white parts of the hindwing strongly reduced. Luzon, flies from January to April. -- mirsdorana Semp. 
has the wings shaped more as in schadenbergi , whilst the sexual spot of the forewing indicates that it belongs 
to lorquini. Under surface with bluish silvery markings in the <$, not undulate but straight at the distal margin 
mindanaen- of the forewing, ocelli of the hindwing in a continuous row. Flies in February. Mindoro. — mindanaensis 
sis. Fruhst' i g larger than lorquini from Luzon, the $ beneath more copiously marked with slate-grey and the anterior 
ocelli are larger. Forewing of the 9 traversed by a broad, continuous whitish band, hindwing with the costa 
bazilana. not yellowish. Flies May to October and again December and January. Mindanao. — bazilana Fruhst. (93 g (J2 
as caerulans $). Chiefly distinguished by the $, in which the median band of the forewing is once or twice inter¬ 
rupted, and by the hindwing, which shows a broad, yellowish bordering to all the ocelli of the upper surface. 
leucogync. Bazilan, in February and March, discovered by W. Doherty. - leucogyne Fldr. is the race from Halmaheira 
in the North Moluccas, which is unknown to me in nature, and to which transitions will perhaps still be found 
on the Sangir and Talaut Island. 
caerulans. P. caerulans Fruhst. is distinguished by a tuft of long hairs on the forewing, otherwise like lorquini <J. 
In habitus and in the shape of the tail intermediate between schadenbergi and lorquini , above lighter blue than 
either. The white submarginal teeth of the forewing similar to those of lorquini , the whitish antemarginal line 
of the hindwing absent. The anal ocellus of the hindwing above, which is very distinct in schadenbergi and want¬ 
ing in lorquini, reduced to a small dot. The under surface of the wings more approaches schadenbergi through 
the absence of the typical silver-grey bordering to the ocelli of lorquini. The under surface of caerulans is. however, 
somewhat less brightly coloured and with smaller ocelli on the hindwing than that of schadenbergi , the grey- 
white markings show a tendency to disappear and hence lean again towards lorquini. Luzon. 
35. Genus: Mycalesis llbn. 
The Mycalesids are among the few genera which are common to Asia and Africa. Their area of distri¬ 
bution is thus very wide. Africa seems to possess the lion’s share, so that Aurivillitjs was able to enumerate 
over 100 species belonging to two genera ( Mycalesis and Henotesia). 
Over the whole of the Indo-Australian Region about 90 species are distributed, of which continental 
India and the Papuan region have nearly equal numbers, a fact which is probably unique in the oriental 
Bhopalocera and can only be due to Mycalesis having developed from two main stocks, so that we must assume 
also two centres of distribution from which the stream of species took its rise. 
Outside these centres (continental India and New Guinea) the number of species decreases compa¬ 
ratively rapidly even in the equatorial zone. In the Macromalayan region there are in Sumatra and Borneo only 13 
species each, on Java only 10 and the same number on the Philippines. China is rather poor in them, the Yang- 
tsekiang Valley yielding about 10, the Loo Choo Islands only two species and the two known Japanese species 
may have spread thence along the North Chinese coast. Celebes, which, as usual, has received contingents from 
four directions (Philippines-Moluccas-FIores and Java-bridges), possesses the very respectable total of 12 species, 
whilst from the Moluccas we only know 5 or 6. About five species inhabit the Micromalayan maze of islands 
ansi Nias has the same number. The South India-Ceylon subregion occupies a peculier position, possessing a 
relatively large number of endemic species which occur nowhere else, and do not even possess near allies (M. occu- 
l itus Marsh., adolphei Guer., patnia Moore). South India alone produces 8 species, Ceylon 6, only 4 or 5 ex¬ 
tend to the Andamans, on the Nicobars not more than 3 or 4 species. From Engano on the south-west coast 
of Sumatra only one species is known as yet; from Banka on its north-east coast six. Also to the east of New 
Guinea the number of species falls off very rapidly. In the Bismarck Archipelago 9 species still occur, on 
the Solomons about 4.
