This clingy little short-winged species, which seems to 
be one of the most widely-distributed members of its 
genus, appears to have been first collected in New Guinea 
by G. F. Mathew in 1884, and in the same year Lord 
Walsingham stated (Notes Leyden Mus., vi, 243) that he 
had lately received specimens from West Africa. Under 
these circumstances it is perhaps somewhat unfortunate 
that its first validly published name should have been 
derived from its occurrence within the circumscribed area 
of Sokotra. 
In some examples there is a great extension of the 
white scaling on the forewing, giving at first sight a 
different facies, but this variation appears to be confined 
to individuals and not to coincide with geographical 
distribution. 
Professor Ur. Rebel, who has very kindly compared some 
Sinhalese examples with the original types of this species 
from Sokotra, writes that in all essential points they are 
in full agreement and that he considers the two forms as 
conspecific, although he adds that in socotranus the palpi 
appear slightly longer and the coloration a little darker 
(less bright red-yellow). This latter point is unimportant, 
but the slight difference in the length of the jjalpi, if 
constituting a constant difference between the two forms, 
may perhaps indicate that we are here dealing with true 
local races (incipient new species); at joresent, liowever, I 
think that we must look on these races (from South aud 
West Africa, Sokotra, Ceylon, etc.) as only forming a 
single “ species ” in the ordinary acceptation of that word. 
The following is a translation of Prof. Ur. Rebel’s original 
description of 1). socotranus :—
