SOUTH-AFRICAX BUTTERFLIES. 
white space at anal angle ; hind-margin widely tinted with dull-reddish, 
and edged with a pale line ; rows of dots obsolete. 
$ Paler, more conspicuously spotted; under side of hind-wing reddish- 
ochreous, only tinged with fuscous next to stripes. 
In some of the more distinctly-marked examples of both sexes, 
there are in the fore-wing two short sub-basal whitish longitudinal 
streaks or dashes — one in discoidal cell just above, and the other 
immediately below, median nervure. 
This little Pyrgus is readily known by its brownish upper side with 
small dull spots ; and by the dull reddish-brown of the under side of 
the hind-wings, crossed by a very distinct continuous median white 
stripe, only a little denticulate on its edges, and not nearly so oblique 
as in Diomus. 
P. Zehra, Butl. {Ann. and Mag. Nat. Hist., 6th Ser., i. p. 207, 
March 1888), is described as " nearest to P. Sataspes it is a native 
of India (" Campbellpore and Chittur Pahar, Major Yerhury"), and, 
judging from the description given, differs in presenting a greyish- 
brown under side of the hind- wings, marked with an additional outer 
narrow white stripe from apex to lower part of hind- margin. This 
additional stripe is a point of agreement with P. Diomus, Hopff. 
I first met with the species at Knysna, Cape Colony, in 1858 ; it was there 
not uncommon, and remained out from September to February 1859. About 
Cape Town I have since constantly taken it, but only in the summer and later 
spring months. In the neighbourhood of Grahamstown I took a few specimens 
during February. There is nothing remarkable in its habits ; like its congeners, 
it is fond of resting with expanded wings on the ground or on stones. 
I have received this butterfly from but few localities, and usually singly ; 
it is inconspicuous, and probably passed over among its immediate allies.
