W. Doherty — A List of the Butterflies of Engano. [No. 1, 
18. Atella alcippE, Cramer. The specimens are quite normal. 
Herr Kheil mentions Atella phalanta, and not alcippe, as occurring in 
Nias, possibly a mistake. 
19. Cyrestis pertander, Fabr. Resembles the Malaccan form {the- 
mire, Honrath), but still darker, much darker than the Tenasserim one, 
which is perhaps a distinct variety. I have not seen the Javanese form, 
but if Horsfield’s drawing is correct, and the insect has only the single 
space between the two outermost ochreous bands white, themire may be 
considered a distinct species. 
A common species in the high forest. 
20. Precis ida, Cramer. Only one taken. 
21. Hypolimnas bolina, Linn. The male is normal, the female in- 
finitely variable. Occasionally it is not much unlike the male. Usually 
the bluish band across the forewing is obscure and there are traces of a 
reddish band from the disc of the forewing across the hindwing, with 
white discal spots beyond it. The white band across the fore wing below 
is present or absent. Sometimes this form resembles Danais pietersii 
when flying. Mr. Woodford has given an interesting account of the 
variability of the female of this butterfly in the Solomon Islands. 
22. Hypolimnas ANOMALA, Wallace. My single male, taken at 
Malakoni, has only the costa and outer margin of the forewing purplish, 
with an outer-discal line of white spots on both wings, a submarginal 
line, and a few discal streaks. The hindwing has no white on the disc. 
No doubt the species is as variable in Engano as olsewhere. 
23. Doleschallia niasica, Butler. I took two or three males 
which may be conspecific with the female described as niasica. They 
are much darker than males of D. hisaltide, the apex of the hindwing 
strongly suffused with black. Herr Kheil gives both niasica and hisal- 
tide from Nias, apparently considering them distinct, but it is unlikely 
that two varieties so closely allied can be found together. I have re- 
cently taken typical Doleschallia pratipa and typical polibete in the 
same piece of jungle in Western Siam, but this is a case of two local 
forms overlapping at the limit of their ranges. The same is true of 
Farthenos lilacinus and gambrisius from Karenni to Lower Siam. 
Family Nymphalim. 
24. Neptis soma, Moore, var. meridiei. Smaller than the Indian 
variety, and darker below, the markings of the upperside somewhat 
smaller and less fuliginous.
