508 Mr. H. Eltringham’s note on the Lycaenidae. 
of Aslauga lambornt a properly prepared microscopic 
preparation shows a difference between the male and female 
fore-feet, a difference which consists in the fact that in the 
male the terminal joint is much swollen, whilst the corre- 
sponding joint in the female, though of about the same 
length, and thicker than those which precede it, is neverthe- 
less not so stout as in the male. 
The persistence of the five-jointed, double-clawed tarsus 
in Lycaenidae occurs in other genera than Aslauga. The 
condition is found in Arrugia, Theclopsis, and Euliphyra. 
In Arrugia basuta, Trim., the femur of the male fore-leg 
is of a pecular shape, having on the under side a pointed 
process of the chitin followed by a secondary smaller pro- 
jection nearer the tibial joint. There is a mere indication 
of a similar structure in the female. The tarsi are not 
distinguishable in the two sexes, and in both the joints are 
equally spine-bearing. The paronychia are remarkable 
in appearing to be double on each side, possibly they are 
merely bifurcated. In EHulvphyra mirifica there is no 
difference between the tarsi of the two sexes, except that 
in the female the claws are rather better developed. 
Of Theclopsis I have been unable to secure an example 
for examination, but Godman and Salvin state that there 
are no paronychia. Preparations of the fore-feet of Liphyra 
brassolis, from specimens kindly furnished by Mr. Bethune- 
Baker, show that they are alike in the two sexes. In the 
male one of the claws seems rather less rounded than the 
other, but a series would be required to show whether 
this is a constant feature. The pulvillus is well developed, 
but there appear to be no paronychia. 
The genera Aslauga, Liphyra, and Huliphyra, more 
especially the two latter, may be regarded as closely allied, 
but Theclopsis and Arrugia are widely separated from 
them and from each other, and the persistence of the five- 
jointed male tarsi must apparently be regarded as an 
independent survival.
