TWO UNCOMMON SUDANESE BUTTERFLIES. Dr. G. B. LoNQ- 



staff exhibited Calopieris eidimene and Teracolus pleione, and 

 read the following notes : — 



Both sexes of Calopieris eulimene were described by Klug 

 in 1829, from specimens taken at Ambukol by Dr. Hemprich 

 and Dr. Ehrenberg. Kirby gives its habitat as Arabia, but 

 Ambukol is on the Upper Nile, about half-way between 

 Dongola and Abu Hamed, in Lat. 18° N. 



In 1896 Mr. A. J. Cholmley, who was attached to Theodore 

 Bent's expedition to the Red Sea, took five specimens at 

 Ambaia Erba, north of Suakin. 



In 1900 or 1901 a single example was taken by a member 

 of the Hon. N. C. Rothschild's expedition at Shendi, between 

 Berber and Khartum. 



These are the only records that I have come across. 



In February 1909 I picked up a single specimen in the 

 western outskirts of Khartum, and a few days later took 

 seven others at Soba, on the Blue Nile, about fourteen miles 

 above Khartum. These were all males. 



In February of the present year I took between Soba and 

 Khartum six more, three of each sex, mostly in indifferent 

 condition. I did not meet with it south of Lat. 15° 30' N. 



Meanwhile, during the past winter, Mrs. Waterfield had 

 been taking it from time to time at Port Sudan, on the Red 

 Sea, getting altogether perhaps a dozen. At the end of 



[lxix 

 February I myself visited Port Sudan, and in the course of 

 a week was fortunate enough to secure eighteen males and 

 nine females. Unless I am greatly mistaken the larva should 

 turn up on the desert Caper (Capparis aphylla, Roth.). 



The purple gleam on the yellow apical spot, which adds so 

 much to the beauty of the butterfly, is only present in the 

 male. 



It will be observed that the specimens from the Red Sea 

 are larger and more strongly marked than those from the 

 Blue Nile. The discal spot is in most cases larger, and there 

 is more black about the apex. Moreover, the yellow nervures
