On new Lepidoptera from East Africa. 125 



4 nervures (rarely 5) in the lower basal cell : hind wing's with 

 9 antenodal and 11 or 12 postnodal nervures ; triangle con- 

 sisting of 4 cells, 2 transverse at the base and the other 2 

 beyond ; 2 supratriangular nervures ; 3 to 5 cross-nervures 

 in the lower basal cell ; raembranule smoky brown, white at 

 the base. 



Allied to 2E. affinis, Van der Lind., of Europe, and 

 2E. Rileyi, Calvert, from Kilimanjaro. Specimens were 

 obtained at Ruwenzori (6000-8000 feet) and " Salt Lake to 

 Wawamba Co." 



Three other species of dragonflies were obtained by Mr. Scott 

 Elliot: — Orthetrum truncation, Calvert (previously known 

 from Kilimanjaro), from Ruwenzori ; Cacergates unifasciata, 

 Oliv. (a species common all over Africa), from the Salt Lake ; 

 and two specimens apparently belonging to a new genus near 

 Agrionoptera, but not in sufficiently good preservation to 

 descri be. 



XVIII. — Descriptions of Three new Species of Lepidoptera 

 from East Africa. By Emily Mary Sharpe. 



Family Pieridae. 



Mylothris Neumanni, sp. n. 



Allied to M. narcissus, Butler, and M. Jacksoni, E. M. 

 Sharpe. 



£ . This new species differs from M. Jacksoni in having 

 the fore wing nearly entirely black, the veins of the discoidal 

 cell marked with white ; while on the discal portion of the wing 

 between each of the median nervules is a hastate mark, which 

 combined forms a white patch in the middle of the wing. 



Hind wing. Primrose-yellow, with a heavy black costal 

 border commencing from the first subcostal nervule and ex- 

 tending below the discoidal nervule. 



The third median nervule is indicated by a black spot at 

 the end. The other nervules are marked by very minute 

 black spots near the hind margin. The base of the wing 

 has a black shading, rather stronger than in M. Jacksoni. 



Underside. White on the fore wing, the apical portion 

 being suffused with primrose-yellow, with a little orange on 

 the costa at the base of the wing.
