African Species of the Genus Acracct. 263 



9. Expanse 70 to 80 mm. Differs but little from the ^J. 

 Wings slightly rounder. The sepia black areas somewhat paler 

 and the h.-w. margin rather broader. 



A. perenna tliespria, subsji. 



In this form the red colour extends over nearly the whole of 

 the f.-w. leaving only the costa, apex, and hind margin 

 sepia black. Oberthiir states that he has three c? c? of this 

 form from Zanzibar, and there is one in the Hope Depart- 

 ment from Mombasa. Aurivillius gives Nyassaland as another 

 locality. It appears to be the Eastern subspieces of jx-'reiina. 

 Examples from Nairobi in the Harrison collection are however 

 of the typical form. 



A. perenna kaffana, subsp. 



This Abyssinian subspecies resembles the thesprio form but 

 differs in the larger size of the f.-w. discal spots, and in having a 

 more extended black basal area, and broader marginal band in 

 the h.-w. 



The larva of A. perenna perenna (PL VI, f. G) is black with 

 long dorsal spines. There is an ochreous dot on each segment 

 just behind tbe origin of the lateral spine. Beneath this a few 

 irregular vertical yellowish marks and below the sublateral 

 spines are longitudinal yellowish marks. The segments bearing 

 the true legs have some additional transverse dorsal yellowish 

 marks. The branched spines and the head are black. (De- 

 scribed from an example received from Mr. W. A. Lamborn, 

 taken near Lagos.) 



A. perenna bears outwardly a close resemblance to 

 A. egina, but can always be distinguished by the marked 

 concavity of the f.-w. hind margin.

* Aurivillius (I. c. sup.) suggests that Hewitson' s A. derhela is an 

 aberration of orina. The type is in the British Museum, and is 

 merely a melanic aberration the identity of which there is some diffi- 

 culty in decitling. Except as a curiosity it is of little importance.
