Pontia daira, Klug, Symb. Phys. pl. viii. figs. b 2 (1829). 
Anthocharis nouna, Lucas, Expl. Alg., Zool. > p. 300, pl. 1. fig, 2 
(1849). 
Anthopsyche demagore, Felder, Reise der Nov., Lep. p. 186 (1865). 
Anthopsyche dalila, Felder, Reise der Nov. ., Lep. p. 188 (1865). 
Teracolus vanthus 1S, Swinhoe, P. Z. 8. 1884, p. 440, pl. xxix, fig. 11. 
Teracolus odysseus &, Swinhoe, t. ec. p. 441, pl. 3.4 fi 3. 
Appears to range from Algeria to Heypt and thence south- 
wards to Abyssinia and Somaliland. 
The type of Felder’s 7. dalila is identical with the typical 
wet-season form, 7. odysseus is an intermediate form, and 
T. nouna (of which 7. 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 cal!s a ‘ job lot.” 
41. Teracolus stygva. 
3. Anthopsyche stygia, Felder, Reise der Nov., Lep. p. 188 (1865). 
Bogos, N.E. Africa. 
This is an intermediate-season form, perhaps not distinct 
from 7. odysseus, 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 Rothschild. 
42. Teracolus Heuglint, 
Anthopsyche Heuglini, Felder, Wien. ent. Monatachr. i. p. 272 (1859). 
Teracolus Thruppi, Butler, P: i S, 1885, p. 770, pl. xvii. fig. 10. 
Teracolus Jamesi, Butler, ¢. 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, 7. Thruppt the inter- 
mediate form, and 7. Heuglind (=D. Jamesi g) the dry- 
season form. 
A3. Teracolus evagore. 
Pontia evagore, Klug, Symb. Phys., Ins. pl. viii. figs. 5, 6 (1829). 
Teracolus Yerburii, “Swinhoe, P. Z. 8. 1884, i 441, pl. Xxxix, fig. 12, 
Teracolus saxeus, Swinhoe, tes pineal hes. 6 
Teracolus Swinhoet, Butler, t.c. p. 491,

T. Yerburti is the wet-season form, 7. Swinhoet may be
