except when flying round the tree-tops in search of the epiphytic mistletoe, its food-plant. 
c. Under surfare of the hindwing with yellow basal spot. 
D. mysa F. (54 f) is the oldest-known species of a small group of Delias which has spread from Australia mysa. 
to Sumatra, mysa-g is above scarcely distinguishable from fruhstorferi-^ (56 d), but beneath as in the $ it is 
grey-black all over, with yellowish basal half to the forewing and 6 orange-coloured, isolated small submarginal 
spots on the hindwing. In Australia distributed from Cairns in Queensland to Sydney, and locally very common. 
D. tnomea. A pretty species only known from Java and Sumatra, where it occurs at elevations of 4-6000 ft., 
flying slowly and heavily. — fruhstorferi Honr. (56 d), hitherto only found in the Tengger Mts., East Java, fruhstorferi. 
has a white under surface to both wings, a broad white discocellular and large white subapical spots on the forewing. 
Hindwing: the submarginal spots yellowish, large, distally pointed. Central area broadly white, the base and 
distal area grey-black. — momea Bdv., from West Java, where it is not rare at Mt. Gede, has the under surface moviea. 
yellow instead of white, with small white subapical dots. The discocellular is black, only ornamented with small 
white dots, hindwing distinctly grey-black with diffuse whitish median spots and small submarginal dots. —■ 
hageni Bogenh. (= datames Nicev.), from the mountainous parts of Sumatra, almost agrees with viomea beneath, harjeni. 
except that the hindwing of the hitherto undescribed $ is completely black, and its upper surface is more broadly 
margined with deep black, with hardly a trace of white dots and the basal part of the hindwing is suffused with 
blue-grey. 
D. itamputi Bibbe (56 f) (name from the Malayan = black-white). Sexes dimorphic, <$ above pure ilampuii. 
white with black, oblique, very broad apical spot. $ above as beneath, only with yellowish white base to both 
wings and in the distal margin of the hindwing without the subterminal row of white patches. Flies in May. 
Aroa River, British New Guinea. 
D. hypsomelas B. & J . i. 1. (56 f). H above as the preceding species, under surface black with 2 yellow hypsomelas. 
apical dots on the forewing, 5 small oblong white subterminal streaks on the hindwing. Locality as the preceding. 
D. aroae Bibbe. H : upper surface as in the two preceding, except that the distal margin of the otherwise aroae. 
pure white hindwing is adorned with a narrow black band, which is somewhat narrowed from the costa to the 
anal angle. The under surface as in geraldina Gr.-Sm. and cuningputi, hut with white median and basal region 
on the forewing and a strongly divided black basal part to the hindwing, on which are placed 2 larger yellow 
patches. The subterminal spots of the hindwing pure yellow, isolated, much larger than in cuningputi. Roth¬ 
schild has figured in Novitates 11 what is supposed to be the $, the under surface of which bears 3 median and 
4 submarginal patches, which are much smaller and more orange-yellow than in the <$. British New Guinea. 
D. cuningputi Bibbe (56 e) (name from the Malayan = yellow-white). U: upper surface grey-white cuningputi. 
with broad distal margin on both wings, which on the forewing encloses 3 small white subapical dots, hindwing 
with very broad white cilia. $ above almost like the <$, but beneath richer in colour, as all the submarginal spots 
and the base of the forewing are tinged with light orange-yellow. The white median area of the hindwing deeply 
incised distally. British New Guinea. 
D. iltis Bibbe (56 e), one of the most brightly coloured species, the pattern of whose hindwing recalls iltis. 
the head-dress of Indians. Upper surface pure white with black discocellular and oblique black apical border, 
in the centre of which are placed 2 white dots. The $ is more broadly margined with black. British New Guinea. 
D. georgina Fldr. A hitherto rare species from the Philippines, of which only 2 $$ are known, taken in georgina. 
March on West Luzon at a height of 600 m. georgina is distinguished by the rounded form of the wings and the 
uniformly spotted under surface, which on the hindwing differs from battana in the absence of the black basal 
dusting, but broader black bands. — battana Fruhst. (54 f). The HU are above lemon-yellow with 2 rows of battana. 
black spots interrupted by yellow, whilst the under surface is paler yellow and has the same latticed pattern as 
the $$ somewhat variable: there occur pale lemon-yellow and more rarely ochre-yellow specimens (f. auricoma 
form. nov.). battana was commonest in misty or even rainy weather. The butterflies came hurrying out of the 
neighbouring wood, straight down from the trees, and were carried by the wind over an adjoining heath. Here 
they could then be captured with little trouble and the natives even brought me uninjured specimens taken with 
their hands. Once in the net these Delias remained completely passive and sat quietly with the wings folded. 
All this was changed in sunny weather. The butterflies flew then at an inaccessible height, encircling the tops 
of flowering trees, and we only succeeded by chance in catching one of them. Flies in February, March at 5-6000 ft. 
on the peak of Bonthain, South Celebes. Not rare. 
D. orphne Wall, has a white instead of yellow under surface to the forewing and the black bands on it orphne. 
only extend to the apex of the cell. Hitherto only 1 £ known, which Wallace caught on Mt. Ophir, Malacca. —
