70 MR..R. TRIMEN ON BUTTERFLIES FROM [Jail. 16, 



males from Miueni Valley. The latter and three others from 

 Christmas Pass are the only males that exhibit to a slight extent 

 the shiuing-greyish underside clouding, that characteristic feature 

 of P. lyceus being absent in the rest. The other distinguishing 

 features of P. lyceus, as distinct from the West-African P. nireus, 

 are, however, well expressed.

Twenty-four males and six females from Christmas Pass, all taken 

 during February. The former without exception have a contin- 

 uous broad or very broad discal black transverse band in the hind 

 wings, but in four of them there is almost an interruption of the 

 band between the 2nd subcostal and radial nervules. The tail 

 of the hind wing is very variable in width and in the extent to 

 which it is spatulate ; in most examples it is black for three-fourths 

 of its length, but in others for about two-thirds and in one for 

 barely half. One specimen presents the very unusual feature of 

 two small spots of the ground-colour in the black border of the 

 fore wings between the 1st radial and 3rd median nervules. This 

 strongly marked form of the male has (with the black-and-white 

 southern form of the female so near the female of P. metope, from 

 West Africa named hippocoon by Eabricius) been named P. tibullus 

 by Mr. Kirby. There is no doubt that it is characteristic of East 

 and South-east Africa, prevailing along the coast from Natal to 

 Zanzibar ; but it occurs along with other less heavily-banded males 

 both in Trans-Kei territory and the eastern districts of Cape Colony. 



The females consist of two near the typical P. cenea, Stoll, but 

 having the markings enlarged precisely as in the two examples 

 from Delagoa Bay which I have recorded in S.-Afr. Butt. iii. 

 p. 249, e ; and four of the black-and-white form near the hippocoon 

 § of P. merope above referred to.

Two specimens from Christmas Pass, a male taken on 19th Febru- 

 ary and a female on the 20th. The male differs from the southern 

 type-form in having the common transverse band rather narrower 

 and with the component spots more widely separated in the fore 

 wings and narrower on costa in the hind wings ; this band is also 

 almost pure white instead of decidedly yellowish white, as are be-
