NEW FOEMS OF BUTTERFLIES. 



By the HON. WALTER ROTHSCHILD, Pii.D. 



L Salamis anacardii ansorgei subsp. nov. 



IN xVor. Zool. X. p. 523 fDec. 1903) we said of 5. anacardii : " We have not seen a 

 specimen of anacardii from the Congo Free State northward to the Niger ; the 

 species does not seem to occur there." Thongh the sentence still holds good, nothing 

 to the contrary having come to onr knowledge, we now believe that on further 

 search anacardii will be found in the districts mentioned. We base this opinion on 

 the fact that Dr. J. W. Ansorge procured in Northern Angola quite a number of 

 specimens of a form of anacardii which comes nearer in characters to the subspecies 

 inhabiting North- West Africa (Sierra Leone, Gold Coast) tlian to the one occurring 

 in South and East Africa as far north as Eritrea. 



This new subspecies is easily distinguished from S. a. uebulosa by the less 

 great extent of the black apical area of the forewing and the clasping organs, 

 differing from S. a. anacardii in the following points : 



S- Upperside of wings much more glossy jnirple ; basal area of both wings 

 usually shaded with purple-grey, this colour limited on forewing by the antemedian 



line which crosses M at base of M-. Forewing : three discal bars SC*'' — R' 



in a nearly straight line, the third bar distinct, the second less proximal than in 

 <S. a. anacardii, the bars about halfway between cell and black apical area ; this 

 area continued beyond R^ by purplish grey scaling, which forms a kind of band in 

 wliich the two black spots M' — SM^ are situated, the band curving distad behind 

 and fusing with another purplish grey band extending along the black distal 



marginal border ; black discal spot M' — M- larger than the spot M- — SM-. 



Hindwing more extendedly shaded with puri)lish grey than in ,S'. a. anacardii. 



Underside as in .5. a. anacardii, more purplish (or milky) white in the 

 specimens with grey bases to the upperside than in the individuals with a purer 

 white upper surface. 



Claspers as in S. a. anacardii. 



Length of forewing : 30 to 37 mm. 



Hab. Canhoca, Angola, end of November and beginning of December 1903 

 (Dr. Ansorge). 



A series. 



2. Apaturina erminea xanthocera subsp. nov. 



(J ? . Club of antenna bright tawny, this colour extending to near base on 

 underside. Macular band of forewing white in both sexes. The blue areas of the 

 upperside of the wings more restricted than in erm. erminea. 



Hab. Guadalcanar, Solomon Is., April 1901 (A. S. Meek & Eichhorn). 



A series.
