to come further west thad Baluchistaa. T. puellarls, with a graea 

 underside, is the vvet-seasou formi aad T. ochrdpennis and T. rorus, 

 with sandy-coloured undersides, represent the dry-season form. 



15. Teracolus testalis. 



Teracolus vestalis, Butler, Proc. Zool. Soc. p. 135, pi. vii. fig. 10 

 (1876). 



Teracolus intermissiis, Butler, Proc. Zool. Soc. p. 152, pi. xxiv. 

 fig. 4 (1883). 



Teracolus duhius, Swiahoe, Proc. Zool. Soc. p. 439 (1884). 



Teracolus peeltis, Swiuhoe, Proc. Zool. Soc. p. 439, pi. xxxix. 

 fig. 9 (1884). 



This species is very nearly allied to the last, and is perhaps 

 doubtfully distinct. However, a few small distinctions appear to 

 be constant : thus, T. vestalis is larger, with the black border ou 

 upperside of secondaries proportionately narrower ; on the under- 

 side of primaries the lowest of the three black spots near posterior 

 angle is small and well-defined, but in T. ^niellaris it is large and 

 suffused along inner margin ; lastly, the females of T. vest all sha,\e a 

 macular discal ray on the underside of secondaries, which appears 

 to be absent in T. puellaris. With regard to the synonymy, 

 T. vestalis and duhius are the same ; T. intermissus is the dry-season 

 form, and T. peelus is merely the yellow female of it. This species 

 has much the same range as T. puellaris, but has been recorded a 

 little further west, namely from Pao in the Persian Gulf. 



16. Teracolus castalis. 



Idmais castalis, Staudinger, Exot. Schmett. p. 43, pi. xxiii. 

 (1885). 



The East-xlfrican representative of T. vestalis, Butl. It occurs 

 in the country lying between Victoria Nyanza and the coast, and 

 as far north as Somaliland. 



17. Teracolus pr.5;clarus. 



Teracolus prceclarus, Butler, Proc. Zool. Soc. p. 769, pi. xlvii. 

 fig. 7 (1885). 



A very distinct and handsome species, of which I have seen only 

 the male and female types in the British Museum from Somaliland. 



18. Teracolus celimene. 



Antliocharis celimene, Lucas, Rev. Zool. p. 426 (1852). 



Anthopsyche pholo'e, Wallengren, Wien. ent. Monatsch. iv. p. 35 

 (1860). 



Anthocharis pkcenon, Ti'imen, Trans. Ent. Soc. (3) i. p. 522 (1863). 



Anthocharis amina, Hewitson, Exot. Butt. iii. Anth. pi. i. figs. 1-3 

 (1866). 



Prom the descriptions given by Wallengren and Trimen, I 

 have but little doubt that this must be the dry-season form of 

 T. celimene, all the distinctions dwelt on by Trimen being quite in
