BREEDING OF FORMS OF THE NyMPHALINE GENUS EURALIA IN 



Natal.— By Roland Trimen, M.A., F.R.S. 



There are three forms of Euralia which inhabit the coast- 

 land of Natal, vid. E. wahlbergi, Wallengr., E. mi ma, Trim., 

 and E. deceptor, Trim. The first and second of these, without 

 being numerous, are met with not uncommonly ; the third, 

 first brought to notice in 1869, and described by me in 1873 

 from a single <$ , has hitherto remained very rare in the 

 Colony. Each of the three forms in both sexes unmistakably 

 and very closely mimics a Danaine of the genus Amauris 

 prevalent in the same district :— thus, E. vxi/dbergi mimics 

 A. niavius, sub-sp. dominicanus, Trim. ; E. mi/ma mimics 

 A. albimaculata, Butl., as well as A. echeria, Stoll. ; and E. 

 deceptor mimics A. ochlea, Boisd. The intimate affinity of the 

 three Euraliae is apparent, although their wing colouring and 

 marking present such wide differences. To this I called atten- 

 tion when describing (Trans. Ent. Soc, 1873. p. 107 and foot- 

 note) E. deceptor, as well as to the fact that E. mima <$ and 

 E. wahlbergi $ had been taken paired.* Since then Mr. A. 1).
