40. Teracolus daira. 



Pontia daira, Klug, Symb. Phys. pi. viii. figs. 1-4 (1829). 

 Anthocharis nouna, Lucas, Expl. Alg., Zool. iii. p. 350, pi. i. fig. 2

Anthopsyche demagore, Felder, Reise der Nov., Lep. p. 186 (1865). 

 Anthopsyche dalila, Felder, Reise der Nov., Lep. p. 188 (1865). 

 Teracolus xanihus $, Swinhoe, P. Z. S. 1884, p. 440, pl.xxxix. fig. 11. 

 Teracolus odysseus j, Swinhoe, t. c. p. 441, pi. xl. fig. 3. 



Appears to range from Algeria to Egypt and thence south- 

 wards to Abyssinia and Somaliland. 



The type of Felder's T. dalila is identical with the typical 

 wet-season form, T. odysseus is an intermediate form, and 

 T. nouna (of which T. demagore is a synonym) is the dry- 

 season form. The latter, owing to its resemblance in the 

 male sex to the dry-season forms of two other allied species, 

 has been united to them and placed in. the next group of 

 species by Mr. Marshall, the whole being united under one 

 heading as what he elegantly calls a u job lot." 



41. Teracolus stygia. 



$ . Anthopsyche stygia, Felder, Reise der Nov., Lep. p. 188 (1865). 



Bogos, N.E. Africa. 



This is an intermediate-season form, perhaps not distinct 

 from T. odysseusj which it nearly resembles ; it is, however, 

 larger and differs slightly in some details of its pattern. The 

 type, which I have examined, is in the collection of the 

 Hon. Walter Kothschild. 



42. Teracolus Heuglini. 



Anthopsyche Heuglini, Felder, Wien. ent. Monatschr. iii. p. 272 (1859). 

 Teracolus Thruppi, Butler, P. Z. S. 1885, p. 770, pi. xlvii. fig. 10. 

 Teracolus Jamesi, Butler, t. c. p. 771. 



Teracolus Jacksoni, E. M. Sharpe, Ann. & Mag. Nat. Hist. ser. 6, vol. v. 

 p. 336 (1890). 



From Somaliland southwards to the Sabaki valley. 



T. Jacksoni is the wet-season form, T. Thruppi the inter- 

 mediate form, and T. Heuglini ( = 1). Jamesi <) the dry- 

 season form. 



43. Teracolus evagore. 



Pontia evagore, Klug, Symb. Phys., Ins. pi. viii. figs. 5, 6 (1829).
