290 SOUTH-AFRICAN BUTTERFLIES. 



wliite 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-iving reddish' 

 ockreous, only tinged tvitJi 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 Fyrgus 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 Diomtis. 



P. Zebra, Butl. {Ann. and Mag. Nat. Hist., 6th Ser., i. p. 207, 

 March 18S8), is described as " nearest to P. SatasjJes;" it is a native 

 of India (" Campbellpore and Chittur Pahar, Major Yerliiry"), 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. Diomiis, Hopff. 



I first met with the species at Knj'sna, 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 Avith 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.
