dry phase (compare this figure with Figs. 6, 7, and the 

 somewhat intermediate Fig. 8). 

 Fig. 6. Precis archesia ^ , under-side of wings ; Salisbury, 5000 

 feet, captured April 30, 1899. The mottled browns and 

 greys of the under-side are very markedly different from 

 the uniform dark brown of the wet pliase. Great varia- 

 tion in these mottled tints occurs in different individuals, 

 harmonizing with the varied appearance of rocks, being 

 at the same time dead-leaf-like. 



7. Precis archesia $ , under-side of wings ; Berea, near Durlxan, 



Natal, captured April 5, 1896, by Mr. D. Chaplin. In 

 this variety of archesia the ground-colour is comparatively 

 unmottled, and to this extent transitional towards the 

 pelasgis form. This difference upon the under-side corre- 

 sponds with a slight approach in the same direction on 

 the upper-side, where the deep red-brown band is broader 

 and more continuous than is usual in typical archesia. 



8. Precis archesia ,^ , mvXer-side oi wings ; variety distinctly 



transitional towards the pelasgis (wet) phase ; Malvern, 

 800 feet, near Durban, Natal. This specimen was cap- 

 tured in coitu with a $ of typical pelasgis, Oct. 7, 1897. 

 The intermediate character is seen in the conspicuous 

 broad light band as well as in the unmottled ground- 

 colour. Comparing this with Figs. 5 and 6, it is seen that 

 in spite of this distinct tendency tow axds pelasgis, the speci- 

 men represented in Fig. 8 is still well on the archesia side of 

 intermediate, and would doubtless be well concealed with 

 its wings closed. The character of the surface of both 

 wings outside the broad band is especially unlike pelasgh, 

 as is the gradual transition of the outer border of the 

 band itself into the ground-colour. The upper-side of 

 the specimen here represented is shown on Plate XII, 

 fig. 5, and that of the ? i->elascjis with which it was in 

 coitu on Plate XII, fi^;. 4.
