Mr. H. Eltringham’s note on the Lycaenidae. 507 
the former being projected hindwards, that is towards the 
head of the insect, much more than forwards, the front 
line being straight, the dorsal apex being projected for- 
wards suddenly but slightly, the dorsal apex itself being 
shghtly but evenly excised: the hinder part is deeply 
hollowed out below the dorsal area, and projected back- 
wards to form a blunt point in the centre of the dorsum : 
the faleces are socketed on to the tegumen on the very 
front line, they are very large and strong, angled at a third 
from the socket and then curved forwards, the apical fifth 
being suddenly reduced so as to form a moderately fine’ 
tip. The aedoeagus is of moderate length, short for the 
size of the insect, of nearly uniform width, with the apical 
orifice arched, extending from the upper side of the tube, 
which is slightly lipped, to the under side, which is rounded 
off. This genus and Liphyra do not appear to me to be 
nearly allied to any other Ruralid group with which I am 
acquainted, though their male armature quite definitely 
shows that they belong to it. It may prove to be that 
they should form a small section of their own, in which 
case the most appropriate name would be the “ Laphyrinae,”’ 
in which I should also include Aslauga. The neuration of 
Iiphyra, Euliphyra, and Aslauga is very close, the general 
shape of the wings is analogous, the life-history of each 
group is quite specialised. Mr. Lamborn speaks of the 
resemblance between the larvae of Aslauga and Euli- 
phyra (p. 451), and both are animal feeders. The legs of 
Aslauga and Liphyra have a quite unusual similarity, and 
I fancy the palpi are also very similar and so are the 
antennae. 
Note on the Structure of the Fore-legs in certain Lycaenidae 
by H. Eltringham. 
As a rule the fore-feet of Lycaenidae furnish an easy 
method of distinguishing between the sexes, but in the 
genus Aslauga, as noted by Schatz and Rober, the male 
fore-feet are not distinguishable from those of the female, 
at least by ordinary methods. The male tarsus is quite 
definitely five-jointed, and the terminal joint is provided 
with two claws, a pulvillus, and paronychia, In the case
