Mr. H. Mace on Bnfterflies on the Nile. 243 



Lycaenesthes otacilia Trimen. One at Soba (Blue Nile, 

 ten miles from Khartoum). 



Azanus ubaldiis Cramer. Fairly common at Khartoum, 

 1909, 1912. 



Calopieris eulimene Klug. One at Burri, Khartoum, 

 and seven males at Soba, 1909. Six between Soba and 

 Khartoum, 1912. 



Teraeolus clirysonoyne. A female near Mogran, Western 

 side of Khartoum, 1909. 



Teraeolus daira. One male at Khartoum, 1909. One 

 between Soba and Khartoum, 1912. 



Teraeolus liagorc Klug. A very scarce butterfly. One 

 at Ad Duwem (Lat. 14° N.), 1909. One at Soba, 1912. 



There are nine species in the collection which are quite 

 new to this district. These are — 



H. eriphia. Previously recorded not liigher than Lat. 13° 16' N. 



B. severina. ,. ., ,. ,, ,, ,, 11° 0' N. 



T. Calais. „ „ „ „ „ „ 13° 16' N. 



T. phisadia. „ ., „ „ „ „ 13° 22' N. 



T. evippe. „ „ „ „ „ „ 13° 22' N. 



T. evarne. „ „ „ ., „ . „ 12° 37' N. 



T. senegalensis. „ „ „ „ ,, ,, 12° 45' N. 



T. hrigitta. ., „ „ ., '„ „ 9° 30' N. 



R.forestan. „ „ „ „ „ „ 10° 0' N. 



It will be seen that there are six species which were 

 previously known no further north than the 12-14 section, 

 one from the 10-12 section, and two which have never 

 previously been taken lower down the river than 10 degrees 

 N. latitude. 



The most striking feature of the collection is the presence 

 of the two species of Terias, both of which Mr. Whitfeild 

 has taken quite freely at Khartoum, though the previous 

 record for senegalensis is four degrees further south, while 

 the most northerly appearance of hrigitta, hitherto, was 

 9 degrees N. Lat. Both are extremely conspicuous 

 insects, not likely to be overlooked by former collectors 

 had they been present. Indeed, Mr. Whitfeild tells me 

 that they are extremely prominent in the lucerne fields 

 by the river, which he finds the most favoured place in 

 the district for butterflies, Pieridae in particular being 

 almost confined to them. The great skipper R. forestan, 

 a very typical Ethiopian species, of which Mr. Whitfeild 

 took only one specimen, had hitherto been found by only 

 one collector, no less than six degrees further south.
