The basal half of the upper surface steel-blue, without the greenish admixture of aphrodite and frankii. Also 
the black costal area of the hindwings more sharply bordered, as in all the Philippine forms. Under surface 
of the forewings with heavier black spots than in the Macromalayan and continental races. The pointed arches 
on the hindwings, particularly between the radials, longer, dusted with pale green. Inner half of the hind¬ 
wings just as pale grey as in aphrodite from Palawan. Semper received specimens taken in East Mindanao in 
October and November, from the South-East of the island between January and March. Doherty took one $

submarginal arches bluish-green instead of grey. Mindoro. Structurally all the forms of franckii have one cha¬ 
racteristic in common, namely the very close proximity of the first subcostal to the costal vein, which almost 
seem to anastomose, calydonia and australis have the subcostalis free. 
P. australis and its numerous allies inhabit the Papuan Region and North Moluccas and Buru. All australis. 
the forms belonging here are, in contradistinction to the West Malay franckii and calydonia , in the process of 
evolution, displaying, with the exception of the shape of the Avings, no constant characteristic outside of 
their persistant variability which affects both sexes in almost even measure; indeed we observe in Prothoe 
australis the very rare case ( Euthalia , Charaxes and Hypolimnas excepted) that also the monoraorphic $3 may 
differ widely in colouring and markings. But on a close examination of the Prothoe forms of New Guinea, we 
find, nothithstanding all their variability, certain characteristics predominating within certain geographical 
limits, which imprint upon the particular subspecies a certain character more difficultly expressed and descri¬ 
bed than recognized by the eyes. Northern Dutch as well as German Ne\A r Guinea have a very large-sized 
form in common. The <$<$ are either black, or have the foreAvings adorned with a broad yelloAvish contiguous 
median band. The £ has on the forewings white elongate median intranerval streaks scaled with violet all 
around. In British New Guinea we encounter a dwarf race of darker colour, lacking on the foreAving the con¬ 
tiguous longitudinal band and, in the $$, the violet irroration. But in their place there exists a form with an 
almost always complete submarginal row of small yellow dots on the forewings, hardly ever seen in hewit- 
soni <$<$. But the median band is reduced, extending in 9 of my specimens only from the middle of the 
Avings to the submarginal line. Moreover, there are always 2 spots in the middle of the costal border of the 
foreAvings, which are not found in 9 of my German NeAv Guinea specimens, although present in 12 from 
British NeAv Guinea. — mulderi Voll. (121 b) has also (J-like spotted with greenish-yellow, with 3 isolate mulderi.

first from Waigeu. Here the predominating form of the G has on the forewing the yellowish median band con¬ 
tiguous (4 out of 5 specimens) and a submarginal row of 4—7 yelloAvish dots; these are very prominent in one
