DELONEURA. By Dr. C. Attrivillius. 
pcrdita. 
exquisita. 
euprepes. 
I. perdita Ky. (64 c) is mentioned as a $ in the description, but it is probably a $. Forewing above 
with a blue spot covering the base of the areas 1 a to 3; hindwing above with a large, blue spot covering the 
discal cell of the areas 2 to 4 almost as far as the margin, and the anterior longitudinal half of the area 1 c. 
Forewing beneath blackish with grey discal spots in 1 b, 2, 4 and 5, a red-brown preapical spot and a greenish 
submarginal line from the costal margin to vein 3 or 2. Hindwing beneath ferruginous with a greenish median 
band and a greenish submarginal line. Cameroon. 
I. exquisita Smith only deviates from perdita by the blue colour above leaving only free the costal 
margin and distal margin of the forewing as well as the margins of the hindwing; besides by the median band 
and the submarginal line of the hindwing beneath being but little metallic. It is probably the <^of perdita. Ogowe 
River. 
I. euprepes Ham. Druce (64 c) entirely corresponds with exquisita above and deviates beneath by 
the discal band of the forewing and the more greenish-scaled transverse lines of the hindwings. Rhodesia. 
Second Group of Genera. 
Vein 6 on the forewing is distinctly separated from the footstalk of the veins 7 to 9 by a slanting, well 
developed, upper discocellular vein; the former footstalk, therefore, seems to rise before the apex of the discal 
cell. The forewing invariably with 12 veins. 
Review of the Genera. 
I. The middle discocellular vein on the forewing is absent; veins 5 and 6 therefore rise from the same place, 
about midway between 4 and 7. 21. Deloneura. 
II. The middle discocellular vein on the forewing is present; veins 5 and 6 therefore always separated at their 
rise. 
A. The posterior margin of the forewing in the distal part emarginated. Veins 8 and 9 of the forewing on 
a long footstalk from 7. 23. Tumerepes. 
B. The posterior margin of the forewing straight or slightly convex. Veins 8 and 9 of the forewing one 
after the other from 7. 
a. Veins 10 and 11 of the forewing on a common footstalk from the anterior margin of the discal cell. 
29. Poivellana. 
p. Veins 10 and 11 of the forewing both rise separately from the anterior margin of the cell, or 10 from 
the footstalk of 7 to 9 and 11 alone separately from the cell. 
*. Vein 9 of the forewing is at least just as long or generally much longer than the footstalk of 7 
to 9. 25. Epitolina. 
**. Vein 9 of the forewing is always much shorter than the footstalk of 7 to 9. 
§. Vein 11 of the forewing is for a long distance united with vein 12. 
26. Phytala. 
§§. Vein 11 of the forewing runs quite separately or it touches vein 12 only in one place. 
1. The posterior angle of the discal cell of the hindwing projects in an acute angle. 
24. Neaveia. 
27. Epitola. 
2. The posterior angle of the discal cell of the hindwing is rectangular and does not project. 
28. Hewitsonia. 
21. Genus: Deloneura Trim. 
The genus was established by Trimen on a very rare South African species. Later on also other species 
have been discovered, and for one of them the genus Poultonia Neave has been established, which, however, 
cannot be distinguished from Deloneura. 
Deloneura is particularly distinguished by the veins 5 and 6 of the forewing rising from the same place 
and being separated from the footstalk of the veins 7 to 9 by a long, slanting upper discocellular vein. 
The deviate from the by the forewing exhibiting a sharper apex, a more convex margin and 
an oblong, narrow, mealy spot on vein 1, and by the forefeet being unjointed.
