286 SOUTH-AFRICAN BUTTERFLIES. 



328. (5.) Pyrgus Agylla, sp. nov. 



Uxp. al., 10 — 1 1^ lin. 



Closely allied to P. Asterodia, Trim., but smaller, 7oith the markings 

 of a ^;w?'cr ichite, and the discal ones larger ; hind- wing with basi-cel- 

 lular spot distinct and well developed, and submarginal spots larger. 

 Under side. — Hind-wing and apex of fore-tving darker in ground- 

 colour, less strongly tinged with ochreous-yellow ; ncrvidar interrup- 

 tions of cilia conspicuously Hack, without admixture of ochreous yellow. 

 Hind-iving : suh-basal and median ivhite hands much more irregidar and 

 denticulate on hoth edges, and more sharply defined hy darker fuscous 

 edging in parts ; — the opposite projections of these bands all but touch 

 each other in two places, viz., at origin of subcostal and of median 

 nervules respectively ; submarginal white spots enlarged, and near anal 

 angle sometimes partly confluent. 



Though so very near Asterodia in most respects, the under side, 

 with its strongly black-marked cilia, and very sharply-defined, irregu- 

 larly-shaped white bands on a ground darker than usual, gives this 

 form a peculiar aspect, rendering it easily recognisable. 



This little Pyrgus seems confined to the dry upland interior districts of the 

 Cape Colony. It was first brought to my notice in 187 1 by Colonel Bowker, 

 who took a few examples (three at Hope Town on the Orange River and one 

 between Somerset East and Murraysburg) in April of that year ; and a few 

 months later Mrs. Barber and he sent three examples from Griqualand West. 

 In September 1872 I took a single specimen at Kimberley. 



In two of Mrs. Barber's specimens the middle spots of the fore-wing are 

 so enlarged as to give the effect of a straight white fascia from costa to sub- 

 median nervure.

329. (6.) Pyrgus Transvaalise, sp. nov. 



Exp. al., 1 1 lin. 



Allied to P. Viiidex, Cram,, and Droimis, Plotz. 



$ Brotvnish-black, with very distinct, mostly rounded, white spots. 

 Fore-wing : spots in disposition and relative size most like those of 

 Promus, but hasi-ccllular sp)ots very narroio and longitudinally elongate, 

 terminal cellular spot more quadrate, and costal spot of discal row 

 narrower and more distinctly tripartite ; spots of strongly-sinuated
