vein 2 rises uncommonly near the posterior angle of the cell, 3 and 4 shortly combined from the anal angle, 
0 and 7 separated. Palpi rather short with a short, lowered terminal joint. 
. Mr. W. A. Lamborn has made the interesting discovery that the larvae of E. mirifica live in the nest 
of an African ant, Oecophylla smaragdina var. longinoda, where they also pupate. They are longish shield¬ 
shaped and above covered by a thick, leather-like skin by which they are protected against the attacks of 
the ants. 
Review of the Species. 
I. Hindwing with a uniformly curved margin and a somewhat extended anal angle. Margin of the forewing 
angled at vein 4. Both wings above dark brown with a large, whitish spot of the posterior margin in 1 a 
and 1 b of the forewing, beneath with violettish-grey ground-colour merging into brown, and whitish-yellow 
and blackish-brown markings. E. mirifica r $- 
II. Margin of the hindwing in the middle distinctly angled. Hindwing beneath with a white ground-colour 
and ring-shaped markings. 
a. Margin of the hindwing projecting the most at the end of vein 2, angled or with a short tail. Wings 
above one-coloured reddish-brown. 
(3. Margin of the hindwing at the end of vein 3 angled. 
*. The wings above brown, towards the apex and margin of the forewing blackish. The forewing above 
with a large, whitish spot covering the apex of the discal cell, the base of the areas 2 to 5 and the 
middle of the area lb. E. mirifica $. 
**. Wings above white with a blackish-brown marginal band of 4 to 5 mm width, and a similarly 
coloured costal margin of the forewing. E. leucyania 2. 
E. mirifica Holl. ($ = hewitsoni Auriv.) (05 c). A. Wings above dark brown; hindwing without 
markings; forewing with a large, whitish, almost square spot of the posterior margin, reaching vein 2; under 
surface reddish-brown, at the margin and base of the hindwing lighter, violettish-grey; forewing as above with 
a light spot of the posterior margin, besides with some brown streaks and a dark submarginal line; hindwing 
at the middle of the proximal margin in 1 b and 1 c with an irregular, white spot surrounded by black, anteriorly 
continued by a dark brown transverse line; one or two dark transverse streaks at the costal margin, and a 
thick, blackisli-brown submarginal line anteriorly and posteriorly pointed. The $ has above a much larger 
white spot of the posterior margin on the forewing, reaching vein 6 and covering the apex of the discal cell; 
the under surface is marked almost as in the but much lighter, for the greatest part whitish. The larva 
discovered by Lamborx lives in the nests of Oecophylla smaragdina , resembles the larva of the allied Asiatic and 
Australian genus Liphyra likewise living in Oecoph ylla, and belongs to the most peculiar larvae of the day-butter¬ 
flies known hitherto. The under surface of the larva is flat and entirely covered by the shield-like expanded 
skin of the upper surface, the sharp margin of the shield covered with small, chitinized cones everywhere closely 
joined to the base. Hereby the soft under surface is well protected against the attacks of the ants. The upper 
surface of the shield is covered with a compact mass of star-shaped, chitinized, small tubercles, and exhibits 
besides on the dark areas chitinized, erect, pencil-shaped formations. The upper surface is brownish-yellow 
with dark brown spots and has along the middle of the dorsum a broad, longitudinal tube deeply furrowed 
longitudinally and laterally undulate. The head is small and very agile as in the larva of Aslauga. Pupa black, 
short and stout. Nigeria to Ogowe. 
E. leucyania Hew. ($ = sjostedti Auriv.) (64 c). Wings above one-coloured red-brown, beneath 
Avhite with grey or greyish-brown spots or transverse bands bordered with dark; forewing with 3 or 4 similar 
spots at the costal margin, and with two similar postmedian transverse bands beginning at the costal margin 
and reaching vein 3; hindwing with several spots in the basal half, a broad, almost straight transverse band from 
the apex of the wing to the middle of the proximal margin and a somewhat curved antemarginal band. In 
the $ the wings are white, above at the base speckled with brown, with a broad, brown marginal band reaching 
the discal cell and vein 6, and a blackish-brown costal margin; forewing beneath with some minute, dark striae 
at the costal margin, a transverse row of three ring-shaped spots dusted with brown about in the middle of 
the areas 4 to 6, and a submarginal row of 4 similar spots of the areas 2 to 5; hindwing beneath with some 
indistinct spots at the base, a broad median transverse band and a submarginal band formed, like the bands 
of the forewings, of ring-shaped spots. Nigeria to Cameroon. 
19. Genus: Teratoneura Dudg 
This peculiar genus seems to me to be most closely allied to Euliphyra. Palpi with a somewhat swollen 
second joint and a thin third joint. The antennae are gradually thickened and almost reach the middle of the
