288 RHOPALOCERA AFRICJE AUSTRAL! S. 



prominence; transverse stripe of upper-side commencing on 

 costa, but widely interrupted on subcostal nervules, and 

 joining a longitudinal white space on inner-margin from base 

 to anal angle, bounded by submedian ; before middle a 

 similar transverse white stripe, commencing with a large 

 costal patch, more or less interrupted on subcostal nervure, 

 and narrowing to join inner-marginal white on submedian. 

 Cilia tinged with yellowish, its interruptions with ochreous. 



? Tar. A, $ and ? (P. Diomus, Hpfr.), Fore-wing : 

 first cellular spot (next base) sometimes wanting, as well as 

 (usually) costal basal spot ; last spot of transverse row often 

 absent; in some specimens an extra clot below central cellular 

 spot. Hind-wing : band more narrow, its direction oblique 

 and towards anal angle, a few whitish scales often indicating 

 its continuation towards costa. Cilia usually more obscured. 

 UNDER-SIDE. Fore-wing : as usual ; the first cellular spot 

 always well-marked. Hind-wing : three oblique white stripes, 

 which appear to have resulted from the confluence, 1, of the 

 basal white with the inner portion of stripe before middle, 

 2, of the costal portion of stripe before middle with inner 

 portion of central stripe, and 3, of costal portion of central 

 stripe with row of white dots, which are confluent, forming a 

 dentate streak ; of these stripes the two first join inner- 

 marginal white, and the third almost does so. 



After a very careful comparison of a long series of specimens with 

 Cramer's figures, I have no hesitation in giving the examples above 

 described as the true Vindex. As regards the presumed variety, the 

 difference of the under-surface of hind -wings is certainly remarkable, but I 

 think not more so than in many banded species of Lepidoptera, in which the 

 confluence of stripes often produces a very distinct-looking form. I have 

 taken specimens presenting this peculiar marking commonly near Cape 

 Town, often flying in company with the typical individuals. I have queried 

 the reference to the "Genera" of Doubieday and West wood, because, not 

 having such abundance of specimens when in England, I was unable to 

 make sure that the example figured was truly Vindex. Hopffer (who, in 

 common with Godart, describes the under side of hind-wings as white, with 

 brown stripes while I consider it, as white-striped on an ochreous ground) 

 thinks that the Vindex of the Encyclopedic is distinct, from Cramer's 

 species, merely because Godart makes no mention of the central brown 

 stripe anastomosing with the hind-marginal brown.

This species is very conspicuous when settled with wings expanded on a 

 stone or low plant, the spots being more purely white than in other South 

 African Pyrgi. It is common around the bases of the Table Mountain and 

 Lion's Hill. Specimens from Kafl'raria are larger and paler beneath than 

 ordinary examples.
