EURYPHENE. By Dr. C. Aurivillius. 
spot in cellule 4 is wanting and that in cellule 2 well isolated. Old Calabar and Cameroons. An aberrant 
australis, female form, $-ab. australis ah. nov., is smaller than the 9 of the type-form and differs in having the oblique 
band of the forewing continuous to vein 3, the spot in cellule 4 being present; the spot in cellule 2 is also 
placed nearer to that in cellule 3; the marginal band of the hindwing is much narrower, indistinctly de¬ 
fined proximally and accompanied by two transverse rows of dark streaks or spots. Congo.

The pecidiarity of this extensive genus is that it connects the very dissimilar species of the genera 
Diestogyna and Euphaedra quite naturally with one another. That is to say, the first species as here placed 
approximate closely to Diestogyna and the last are scarcely distinguishable in form and markings from 
Euphaedra. Indeed Euryphene agrees so completely in the build of the body with Euphaedra that, as the synop¬ 
sis (23. 143) shows, the only difference is in the colour of the palpus. 
The species of Eurypliene are medium-sized to rather small Nyni23halids, which have their head¬ 
quarters in the West African forest-region and in German East Africa are only represented by a single 
S 2 )ecies; southwards they do not extend beyond Angola. 
The 99 are on an average larger than the CS and usually also differ considerably from them in the 
colour and markings of the upper surface. On the underside on the contrary the sexes are similarly marked 
and hence it is always easy to recognize the identity of the and 99- 
Of the earlier stages only the 23vq3ae are known. The pupa-case is thin, the form angular; the head 
has two conical points and on each side in the middle near the jiosterior end of the wing-cases there is a sharp 
angle; the dorsal surface is sharply keeled, gradually rising in height from the head to the third segment of 
the abdomen, where it terminates in a long conical spine and then gradually slopes down again towards the 
cremaster, forming some small elevations in the dorsal line; the cremaster is rather long and nearly straight. 
The S23ecies are divisible into several groups, the most important characters of which are given in the 
following synopsis. 
Synopsis of the Groups. 
I. The 99 above with a light yellow-whitish median band on the hindwing, narrowed towards the inner 
margin, and with a pattern which strongly recalls that of the Catuna species. In the $<$ the upper 
surface of the wings is orange, brown-yellow or black-brown with 4 or 5 blackish transverse bands 
or nearly black with blue reflection; they differ from similarly coloured <$<$ of other groups partly in 
the smaller size (ex|3anse 50—55, rarely u|3 to 60mm.), }3artly in having the under surface never green or 
greenish and the base of the costal margin of the hindwing beneath never white; forewing always 
without subapical band above. Second Group. 
II. The 99 never have the Catuna- like markings above and have no yelloAV transverse band on the hindwing. 
A. Hindwing beneath with dark costal stripe, commencing at least at the first quarter of the costal margin 
and reaching the apex; hence at least the last three quarters of cellule 8 are much darker than the 
ground-colour. 
a. The costal stripe on the underside of the hindwing is about 3 mm. in breadth, starts from the base 
and covers not only the base of the cell and cellule 8, but also the greater part of cellule 7. 
Both wings above with red-yellow ground-colour. First Group. 
b. The costal stripe on the underside of the hindwing only begins at the first quarter of the costal margin 
and is posteriorly bounded by vein 8, consequently covering only the narrow distal part of cel¬ 
lule 8; the ground-colour beneath bright light yellow. Both wings black above, for the most part 
suffused with bright greenish blue or light blue. Seventh Group. 
B. Hindwing beneath without dark costal stri})e. 
a. Wings beneath with a distinct, common, narrow, straight, dark transverse band, extending from 
the a 2 >ex of the fore wing to the anal angle of the hindwing at the extremity of vein lb. 
Fifth Group. 
b. Wings beneath without common transverse band or with a transverse band which terminates 
at the middle of the inner margin of the hindwing. 
*. Wings beneath without markings in the cell or with dull, never }mre black s 2 >ots. 
f. Forewing above with 2 or 3 transverse rows of white s}3ots beyond the cell. 
Sixth Gro u p. 
ft- Forewing above without white spots beyond the cell or only with white subapical band 
or white rings to the subapical dots. 
§. Forewing above with a broad yellow transverse band, beginning at the middle of 
the costal margin and reaching vein 2. Fourth Gro u p. 
§§. Forewing above without light transverse band or with a subapical band which at most 
reaches vein 3 or shades into the ground-colour without any sharp delimitation 
Third Gro u p. 
Eighth G r o u |3. 
**. Both wings beneath with pure black spots in the cell.
