1894.] MANICA, SOUTH-EAST ATBICA. 61 



Eiver in Mashunaland exhibits the same peculiarity in the hind 

 wings, but in the fore wings is ahnost as much clouded with 

 fuscous as usual, and I have two quite similar males captured by 

 Mr. H. M. Barber on the Tenda Eiver, N.E. Transvaal, in 1888. 



108. Al.ena ivYASSA, Hewits. (Plate VI. fig. 15, $ .) 

 Alcena nyassa, Hewits. Ent. M. Mag. xiv. p. 6(1877). 



Two females of this strikingly-marked Alana — one taken in 

 Mineni Valley on the 7th March, and the other in the Pungwe 

 Valley on 1st September. 



This species was founded on four examples sent from Lake 

 Nyassa by Mr. Simons. Hevvitson's description was evidently 

 made from a male, as he notes the costal portion of the curved 

 w^hite bar of the fore wings as consisting of three " minute " 

 divisions,while in the female (where the curved white bar, as well as 

 the corresponding bar in the hind wings, is much broader and of a 

 purer white) that part is of considerable size \ The female is 

 much larger than the male, expanding Ig inches, and her wings 

 are much broader and more rounded hind-marginally. 



A male taken at the Shashina Ri\'er, Matabeleland, by Mr. 

 Selous in 1883, has the transverse black markings of the hind 

 wings exceedingly reduced, the submarginal streak between radial 

 nervule and inner margin being indeed quite obsolete.

One male and three females taken at Christmas Pass during 

 February, The females are all different on the upperside — one 

 being exceptionally dingy owing to the almost obsolete condition 

 of the usual whitish or white discal marking, another with small 

 but distinct white marking, and the third with a wide development 

 of faint bluish-grey extending from near base over lower discal 

 area in both fore and hind wings". 



Mr. Selous notes that he found this Butterfly drinking at the 

 water's edge in company with other Lycsenidae. 



' In another Mashunaland female captured " between Makoni's and the 

 Odzi " in 1891, by Mr. Selous, the white bar in the fore wings is a little 

 narrower throughout, but the white subapical spot, sometimes found on the 

 upperside between the subcostal nervure and the upper radial nervule, is elon- 

 gated and conspicuous. 



^ The South- African Museum has lately received from the Eev. Dr. Holland 

 four female specimens of Larhnocvema taken in the Ogove Valley, Gaboon 

 Territory, in West Africa, which, except in size, cannot be distinguished from 

 L. hibuhis. They expsmd 1 in. 2-|-.3^ lin., while the range of expanse in South- 

 African female L. hihulns is 10| lin. to 1 in. 2 lin. One of these Ogove examples 

 has only the faintest indication on the upperside of the usual pale discal mark- 

 ings, and in the others those markings are limited and rather ill-deflned.
