The genus Lycaenesthes was created by Moore in 1865 
(Proc. Zool. Soc. Bond,, 1865, p. 773) for the reception of 
his species L. hengalensis, i.e. emolus, Godart. The neura- 
tion is quite ordinary, and is very closely allied to Nacaduha 
and Jamides, from which however, it may be known by the 
possession of three short hair-like tails in the secondaries, 
this characteristic will also separate it from almost all 
other genera of the Lycaenidae. The Oriental species 
require a good deal of sifting, whilst those obtaining in 
Africa are much in the same condition in spite of the 
fact that Aurivillius dealt with the genus so admirably in 
his able work, “Rhopalocera Aethiopica ” ; since the issue of 
that book, however, a considerable amount of material has 
come to hand, and we are thus in the position of being 
able to elucidate many points and species. Africa may be 
said to be the headquarters of the genus; it was the un¬ 
ravelling of many species from the West Coast, together 
with Doherty’s collection from the Mau Escarpment in 
the Tring Museum, that necessitated my taking up a more 
detailed study of the genus, and thus led to the present
