1891.] W. Doherty — A List of the Butterflies of Engano. 
Elymnias 'panther a, Java, resembling dolorosa, as described by Mr. Butler 
from Nias. The forewing, however, is scarcely paler outwardly, its lower 
angle generally suffused with reddish ; the ocelli of the hindwing are 
placed in diffused pale spots. Underside with two or threo minute ocelli 
on the forowing, and six on the hind wing the first nearly all white, the 
others blue with the outer end dark and the pupil white. The outer 
part of the wing is but slightly paler than the inner, and is not “ stone 
yellow striated with blackish ” as in dolorosa, but pale grey-brown with 
red stria) similar to those of the base. E . dolorosa has the hindwing more 
strongly dentate than in pantliera, with a decided tail, but in the Enganese 
form the tail is much less distinct than in panthera. I took only 
females. The sex of the type of dolorosa is not stated. 
Family Mobphid^!. 
16. Amathusia amythaon, Doubleday, var. insdlabis. Above 
black, the disc glossed with blue in some lights up to the border of the 
hindwing, but not apically on the forewing, the marginal line white. 
The lilac band is somewhat intermediate between that of A. portheus, or 
dilucida, and that of A. westwoodii, tapering less than in the latter, ex- 
tending down to the internal, and up to the upper median vein near the 
outer margin, very broad costally. Below, the extensive space beyond 
the middle striga of tho hindwing almost to the submarginal line is 
dusky in both sexes, without the lilac gloss of the rest. On the fore- 
wing there is a smaller dusky patch chiefly costal, beyond the fifth 
striga. These dai - k spaces are scarcely visible in the allied forms. The 
underside seems generally darker than in weshvoodii, the ocelli have 
broader dark borders, the tails are much broader and more marked with 
white than in any other variety ; the anal black spots are touched with 
blue in both sexes. 
The ochreous hand of the female is narrow, bifid near its lower end, 
deeply incised outwai’dly along the middle median vein and partly en- 
closing a dark spot in its inner margin above the same vein. 
One of the numerous local forms of Amathusia amythaon, which are 
by some held as species. I am unluckily unable to compare it with 
Felder’s J avanese varieties. It differs from portheus and dilucida in the 
broad tails and narrower bine band. It is like Westwood’s amythaon 
(now called westiooodii) , of uncertain habitat, but the band is less 
tapering, broader outwardly, the tails much broader, and the outer 
margin of the forewing convex instead of concave.
