 very few butterflies are on the wing before 7 o'clock, 

 whilst the early morning hours are a time of great activity 

 for birds.] 



[Rahai, Aug. 29, 1908. 



Some of the smaller Acrseas are anything but con- 

 spicuous on the under side, — even A. enccdon which is so 

 abundant and widely distributed. It is no doubt an ad- 

 vantage to them to be fairly well concealed in the position 

 of complete rest.] 



1. Resemblance, hetiveen a female Teracohcs vesta and a 

 female Belenois severina taken together at Taveta. 



E. B. P. 



When looking over the PieriniB captured by the author 

 at Taveta, I noticed a female specimen of Teracolus vesta, 

 Reiche (represented on PI. XXIX, fig. 9), which strongly 

 suggested the facies of the female of Belenois severina. 

 When I turned to the series of this latter species, it was 

 at once seen that on the very day (April 25, 1905) on 

 which he had captured the Teracolus, a female severina 

 closely resembling it had also been taken. The specimen 

 is figured on PI. XXIX, fig. 8. The pale salmon tint which 

 usually appears on T. vesta is wanting from the upper 

 surface of this specimen, of which the ground colour is a 

 very pale greenish-yellow like that of the Belenois. The 

 oblique black marking which starts from the costa of the 

 fore-wing and crosses the end of the cell is strongly de- 

 veloped in the severina, closely resembling the Teracolus, 

 in which it is a characteristic feature of the upper surface. 

 Beneath, the yellow and orange tints and dark markings 

 are very different in detail, but their general effect is the 

 same. On the wing and at rest from a little distance, the 

 butterflies would be indistinguishable. E. B. P.
