2. Subfamily : LycaenSnae. 
The differences between the Lipteninae and Lycaeninae are stated above on p. 297. 
The Lycaeninae form a division more abounding in species and occurring in all the parts of the world, 
being represented everywhere in the Ethiopian region. Most numerous, however, they are in South Africa. 
The great number of genera belonging hereto may be divided at least in 5 groups. 
Review of the Groups of Genera. 
I. The first joint of all the tarsi is depressed and at least twice as long as the other joints together. The hind¬ 
wing with a long precostal vein turned round towards the base. Palpi extremely long, projecting far beyond 
the head. Eyes bare. First group of genera. 
II. The first joint of the tarsi cylindrical and of a normal length. Hindwing without the precostal vein. 
A. All the legs as far as the second foot-joint densely long-haired. Eyes hairy. Hindwing rounded off 
without any corners or small tails. Second group of genera. 
B. At least the tibiae and tarsi with appressed scales without any long hair; very rarely hairy, the eyes, 
however, in this case bare. 
a. Hind wing at the end of vein 1 b lobate, tailed or angled, rarely almost rounded off, but then the 
antennae short, strong, gradually thickened with an indistinctly deposited circular club. The proximal 
margin of the hindwing almost invariably more or less excised between the veins 1 a and 1 b. 
*. Hind wing at the end of vein 1 b on the proximal side with a very distinct lobe turned backward, 
but without any small tail at all; at vein 2, however, tailed. Eyes densely haired. Forewing 
always with 11 veins, 7 and 8 rising on a long footstalk. Third group of genera. 
**. Hindwing at the end of vein 1 b tailed and generally also lobate (the lobe, however, turned proxi- 
mad not backward), rarely rounded off without a lobe or small tail. 
Fourth group of genera. 
(3. Hind wing at the end of vein 1 b rounded off and generally less prominent than at vein 2 . never lobate 
tailed or angled at vein 1 b, with a fine hair-tuft at most. Proximal margin of hindwing straight 
or a little convex, rarely feebly emarginated between the veins 1 a and 1 b. Antennae very fine, 
their shaft with long distinct joints and with a more or less depressed club. 
Fifth group of genera. 
First Group of Genera. 
This group is in Africa only represented by a single genus. Vein 6 of forewing rises from the footstalk 
of 7 and 8, vein 9 being absent; veins 10 and 11 separately from the costal margin of the cell. 
Antennae rather strongly built; the shaft indistinctly jointed and the club very little thickened, circular. 
Palpi very long, 3 or 4 times as long as the head, compressed and with appressed scales. Eyes bare. Legs with 
appressed scales. Forewing with 11 veins; vein 5 from the middle of the almost straight transverse vein of 
the discal cell; the veins 3 and 4 of both wings almost from the same place; veins 6 and 7 of the hindwing 
from the same place or rather remote from each other. 
1. Genus: Mcgalo|»al|>us Bober. 
The sexes are similarly coloured, but distinguished by the margin of the hindwing being in the $$ 
almost entirely rounded off, in the $$, however, in the middle (at the end of vein 5) broad and obtuse. 
All the species are above white, the costal margin and apical part of the forewing being black. 
Mr. W. A. Lamborn has recently discovered the habits of the larvae of Megalopalpus. They are carni¬ 
vora feeding on little species of the Jassids and Membracids which they grasp with their forlegs. The Homoptera- 
larvae are visited and protected by the ants of the genus Pheidole. The ants, however, seem not or only little 
to care for the larvae of Megalopalpus.
