90 MR. R. TRIMEN ON BUTTERFLIES [Jail. 20, 



72. Chrysorychia amanga (Westw.). 



c? 2 . Zeritis amanffa,'Westw., Oates' 'Matabele-land,' &c. p. 351. 

 n. 62(1881). 



Omrora (August and November) and Humbe (October). Ten 

 examples ; six males and four females. 



These males on the upperside differ from the Transvaal one 

 figured in 'South-African Butterflies' (ii. pi. 9. f. I) in the much 

 larger red field in the fore wings, extending more or less over the dis- 

 coidal cell and the upper discal area beyond the cell. Both sexes have 

 the underside of a very uniform reddish-ochreous — a character 

 which I have previously noticed in some of the females only. 



Genus Zeritis, Boisd.

74. Zeritis aranda (Wallengr.). 



S . Cygaritis aranda, Wallengr. loc. cit. 1857, p. 43. 



Omrora (August). Three male examples. 



On the underside the ground-colour in these specimens is duller 

 and paler than usual, but the sub-metallic spots of the hind wing 

 are whiter and more shining. 



75. Zeritis molomo, Trim. 



$ . Zeritis molomo. Trim. Trans. Ent. Soc. Lond. 1870, p. 373, 

 pi. vi. f. 9 ; and var. A ( c? 2 ), S.-Afr. Butt. ii. p. 206 (1887). 



Humbe (October), Okavango River (December), and Omaramba- 

 Oamatako (January). Nine examples ; four males and five females. 



These specimens approximate more nearly to the var. A above re- 

 ferred to, but are decidedly smaller than usual. The males have the 

 fore wings longer apically, and the anal angular projection and short 

 tail of the hind wings longer; the orange ground-colour is brighter, 

 the dark costal patch is larger in both fore and hind wings, and the 

 dark border of the fore wings is wider at the posterior angle. The 

 females are nearer to the typical form than usual in having the 

 hind-marginal border of the fore wings but shghtly pierced by 

 nervular projections of the ground-colour. 



7^. Zeritis damarensis, n. sp. (Plate IX. fig. \7 6 •) 



S . Exp. al. 1 in. 4-5^ lin. 



Closely allied to Z. molomo, Trim., but much larger. Orange- 

 yellow paler and duller and in both wings restricted to discal area, 

 the basal area being widely obscured with ochreous-fuscous.
