of the markings on the under side of the wings. The females in many of 

 the groups are wonderfully alike on the upper surface, and it is onh' 

 hy a careful study of the l^andings and markings on the under side of the 

 wings that it is ix)ssible to make a correct reference of the females to 

 the corresponding males. JNIany of the females have not yet been figured 

 in any work, although verbal descriptions of a number of them have been 

 recently given by Dr. Aurivillius in the latest revision of the genus, 

 which is contained in Seitz's ' Gross-Schmetterlinge der Erde,' Vol. XIII. 



(221) 1. Euryphene carshena Hewitson 



Euryphene carshena Hewitson, 1871, Exot. Butt., IV, Euryphene, PL vii, figs. 31, 

 32, &. Aurivillius, 1912, Seitz, Gross-Schmett., XIII, p. 171, PI. xlic?,/. 



This species is characterized in both sexes by the presence on the 

 under side of the wings, above the outer upper angle of the cell of the 

 hind wing, of a broad, very conspicuous brown spot, which shows itself 

 even more conspicuously in the case of the females than in the case of 

 the males. 



The collection contains four males; two taken in April and two in 

 September, and four females taken in July and August. All the speci- 

 mens were captured at Medje.

This insect, which may be only a seasonal variety of E. tentyris 

 Hewitson, differs from the latter in the entire absence of the brilliant 

 blue-green coloration of the costal area of the fore wing in the male sex. 

 In indirect light there is a faint violet sheen discernible upon the disc 

 of the fore and the hind wings. On the under side of the wings this form 

 is absolutely like typical tentyris. We have large numbers of this form 

 collected for us in southern Cameroon. 



The species is represented in the Congo Collection by a single male 

 specimen captured at Niangara, November 26, 1910.
