NEPTIS. By H. Fruhstorfer. 605 
from the Mentawej Islands is smaller than tullia, having the white markings greatly obscured and reduced. 
N. nata has likewise its chief home in the Macromalayan Region, although I have taken some few specimens 
as a great rarity in Tonkin. Moore was the first* who called attention to the fact that it is subject to sea¬ 
sonal Dimorphism which finds its expression in the confluence of the white stripes in the cell of the forewing. 
—- leucoporos Fruhst. appears to be the plainest of all the known forms, having the white bands greatly reduced leucoporos. 
in width, and the subapical and submedian spots represented by mere dots. The white triangle before the apex 
of the cell on fore wing is separated from the basal streak by a much broader black transverse spot than is seen in 
any other of the remaining forms. Under surface darker brown with jet-black submedian bands. Tonkin, Chiem- 
Hoa, August and September, collected by H. Fruhstorfer. -— cresina Fruhst. (126 b as ‘charori’) from the cresina. 
Malay Peninsula is not identical with nata Moore from Borneo, but differs from it in the more rounded contours nata. 
and in that the ground-colour underneath is rather black than red-brown. All white markings are of a clearer 
tint, more sharply defined and rather milky-blue instead of greyish or yellowish. Moreover the white spots 
are on forewing more delicate, on hindwing, especially beneath; more pronounced. Type from the Malay Peninsula 
where it occurs as far as Tenasserim, and in North-East Sumatra. — agathyllis Fruhst. corresponds to the agathyllis. 
dry-season form (in Moore’s sense), contrasting with cresina and especially also with nata nata <$<$ with 
their sharp pointed wings, by its larger size and the more rounded contour of wings. The apical spot and 
basal streak in cell on forewing are either completely united or only separated by a faint line which under¬ 
neath disappears completely. Under surface: Basal streak at costa of hindwing as well as the subbasal stripe 
which in nata is occasionally obsolete, longer, much broader and clearer white, which, together with the more 
prominent submedian and submarginal bands on forewing, characterize agathyllis as a distinct form; apparently 
it is limited to the Mountain Region, since similar specimens appear also on Kina Balu to be by far the most 
common Neptis. All the specimens at my disposal come from the Mountains of West Sumatra. In Borneo 
nata appears to be closely resembling cresina, forewings with more prominent white subapical spots on either 
side; under surface paler grey. Much more common than nata, however, we find on Kina Balu the fa. ra- rasilis.

wings. A much greater difference is presented by egestas Fruhst. which in either sex resembles leucoporos, egestas. 
from which it deviates in the somewhat broader white submarginal band on hindwing. Otherwise all spots 
and bands are greatly reduced in extent as compared with nata nata and, particularly on foreAving, much 
shorter, more rounded and farther apart. Ground-colour underneath red and not blackish-brown. South-

and in the markings of the upper surface, which only differs in the clear white and slightly blue-opalescent 
spotting. Beneath it deviates more essentially in having the ground-colour reddish instead of grey or brown- 
black, the submarginal line on forewing more strongly undulate, and in the nearly red-violet, more prominent, 
submedian and submarginal bands on hindwing. From Java, Avhere it is very scarce; at present I possess 
only 2 $$ taken on the Vulcano Gecle at an altitude of 4000 ft., and 1 $ from eastern Java taken at 2000 ft.

N. nandina is represented by a great number of subspecies, inhabiting the entire Indian Region and nandina. 
the archipelagoes from Formosa and the Philippines to the Andamans and the Macro- and Micromalayan 
Islands. In the West, especially in northern India, the species is highly susceptible to climatic influences, which 
renders a recognition of the various forms a matter of great difficulty. On account of the existence of inter¬ 
mediate forms between this and the following species soma Moore, their markings afford us no sure means of 
distinction between the two. But the sexual organs are highly specialized, those of nandina differing from 
soma in the absence of a subbasal prominence terminating in a sharp pointed spur. Uncus smaller, more 
pointed, valve with distal spur placed farther inwards, much larger and curved upwards like a boar’s tusk. 
Going from North to South we meet the following subspecies: formosana Fruhst. (126 g) has according to the formosana.

with grey. The latter specimens presumably belong to the rainy-season form. The under surface is remarkable 
for the deep cocoa-brown ground-colour, from which the relatively broad white bands stand forth very plainly.
