LEPIDOPTERA. 



Sea. This genus is tropical, chiefly Indian, and no species was captured 

 by Mr. Lord according to Walker, so that this outlying station is very 

 interesting. Mr. Janson informs me that there was an unnamed specimen 

 of this ant in the British Museum. 



LEPIDOPTERA. 



NYMPHALID^. 



Pyrameis cardm, Linn. Wddy es Sheikh in Sinai, in a clump of 

 tamarisks. ' This well-known butterfly is found in nearly all parts of the 

 world except Australia, where it is replaced by the closely-allied P. Ker- 

 shawi, McCoy.' Mr. Lord captured it at Cairo and in Upper Egypt. 



PIERID^. 



Pieris {Belenois) lordacea, Walk. Gh6r es Safieh at the south end of 

 the Dead Sea. Described from specimens collected by Mr. Lord at 

 Harkeko, on the African shore of the Red Sea, in lat. 15°. Mr. Walker 

 states that this butterfly belongs to the group of which P. mesentina, 

 Cram, (also an Ethiopian form) is the type, and has much affinity with 

 that species. The two were in company at Harkeko, and it will be 

 interesting to know if P. mesentina also occurs in the Gh6r. A charac- 

 teristic example of the tropical conditions of the Ghor. 



Teracolus phisadia, Godt. These butterflies were just emerging from 

 the pupa state, which were attached in great abundance to the twigs of a 

 species of Rhamnus by the edge of the river Hessi in the Ghdr. Known 

 only from Aden and Abyssinia twenty degrees further south. 



T. chrysonome, Klug. Gh6r es Safieh. Known from Ambukohe in 

 Somali, fifteen degrees south of the Gh6r. Wallace, in his ' Distribution 

 of Animals ' (ii., 478), states that two genera of Pierida;, of which the 

 present is one, are confined to the Ethiopian region. Teracolus is known 

 by about ten species from Madagascar, Arabia, and S. Africa. These 

 last three butterflies offer_ satisfactory illustration of the view of the past 

 northern range of tropical forms along the Red Sea and the 'Arabah to the 

 Gh6r, now interrupted by the aridity of the climate. None of these were 

 captured by Mr. Lord or myself in Sinai.
