LYCAENESTHES. By Dr. C. Aurivillius.

Review of the Genera. 
A. Hindwing at the margin with 3 (or rarely only with 2) hair-tufts at the ends of the veins 1 b, 2 and 3. 
25. Lycaenesthes. 
B. Hindwing without any small tails or hair-tufts or only at the end of the vein 2 with a short tail. 
a. The upper discocellular vein of the forewing is present and generally very slanting; vein 7 or the foot¬ 
stalk of 7 and 8 of the forewing therefore rises separate from vein 6 and apparently a little before 
the apex of the discal cell. Forewing never beneath in the discal cell with more than a black dot. 
26. Cupido. 
(3. The upper discocellular vein of the forewing is absent; veins 6 and 7 of the forewing therefore rise always 
from the same place or on a short footstalk. Forewing beneath in the discal cell with two black dots situate 
in a straight line with the spot at the end of the discal cell. 27. Heodes. 
25. Genus: I^ycaenestlies Moore. 
The African species of this genus occurring also in South Asia have recently been dealt with in an excellent 
monography by G. F. Bethttne-Baker (Transs. Ent. Soc. London 1910, p. 1 to 84, 13 tables). Although 
I consider it at least for the present to be advisable to regard his genera as subordinate genera, I shall 
otherwise follow this monography in all the essential parts. Bethune-Baker established five genera which 
he distinguishes in the following way. 
A. Forewing with 11 veins; vein 9 is absent, but vein 8 is distinct, though sometimes very short. 
y.. Veins 10 and 11 rise from the costal margin of the discal cell and run quite separately. Cupidesthes. 
Lycaenesthes s. sir. 
(3. Vein 11 of the forewing rises separately, but then it is fused with vein 12 for some distance; vein 8 very 
short. Neurypexina. 
B. Forewing with 10 veins; veins 8 and 9 are both absent. 
a. Vein 11 runs separately without being fused with vein 12. Neurellipes. 
[3. Vein 11 is for some distance fused with vein 12. Triclema. 
Cupidesthes was established by me in 1895 for a species with bare eyes (all the other species have distinctly 
often very densely haired eyes). Bethttke-Baker added to Cupidesthes several species with hairy eyes. But 
it is not clear to me how in such a case Cupidesthes and Lycaenesthes can be distinguished; for the differences 
in size, robustness of the body and shape of the wings do not form a distinct limit. The other genera are easily 
discernible; it is, however, questionable whether the disappearance of vein 8 or the fusion of vein 11 with vein 12 
may have been brought about quite independently in different species, and that thus species with 10 veins 
are not more closely allied to each other than to species with 11 veins. 
And, moreover, the structure of the veins may vary in the same species. There are for instance several 
specimens before me of L. lusones, in which vein 8 of the forewing is distinct and vein 11 for some distance 
fused with 12. It is therefore impossible for me to maintain yet the ,,genera“ Neurypexina, Neurellipes 
and Triclema as groups of species. 
Review of the Groups of Species. 
A. Eyes bare — Subordinate genus Cupidesthes Auriv. First Group. 
B. Eyes distinctly, usually very densely haired. 
1. Forewing beneath from the base to the apex of the discal cell imi-coloured without markings or only 
with a black longitudinal streak at the base of area 1 b. Palpi beneath smoothly scaled, without bristles. 
Second Groxqx. 
2. Forewing beneath also in the basal part, with markings. Third Group. 
First Group of Species. 
This group only comprises one species. The other species combined with it by Bethune-Baker I 
place to the second group. Forewing with 11 veins; vein 11 running separately. Palpi with appressed scales, 
without bristles.
