Pierine Butterflies of the Genus Terias. 67 



29. Terias Bewsheri. 



Terias Bewsheri, Butler, Ann. & Mag. Nat. Hist. ser. 5. vol. xv. p. 190 



(1879). 



Terias chalcomiceta, Butler, I. c. 

 Terias dentilimbata, Butler, I. c. 



Island of Johanna. 



T. Bewsheri is the wet form and T. chalcomiceta and 

 var. dentilimbata the dry. 



There can be little doubt that this is merely an insular 

 race of T. senegalensis , less subject to variation than the 

 continental type. 



30. Terias leonis. 



Terias leonis, Butler, Ann. & Mag. Nat. Hist. ser. 5, vol. xvii. p. 222, 

 pi. v. fig. 6 (1886). 



West Africa from Sierra Leone to the Gaboon. 



A small species, perhaps doubtfully distinct from T. sene- 

 galensisj but apparently having no dry-season form ; the 

 typical (intermediate) form is more characteristically dis- 

 similar from T. senegalensis than the wet form. 



There are twenty-eight examples in the Museum series.

Terias senegalensis, Boisduval, Sp. Ge"n. Le"p. i. p. 672 (1836). 



Terias solifera, Butler, Ann. & Mag. Nat. Hist. ser. 4, vol. xv. p. 396 



(1875). 

 Terias bisinuata, Butler, Ann. & Mag. Nat. Hist. ser. 4, vol. xviii. 



p. 485 (1876). 



Terias orientis, Butler, P. Z. S. 1888, p. 71. 

 Terias utleri, Trimen, S. Afr. Butt. iii. p. 23 (1889). 



Africa generally, but apparently rare in the south. 

 T. seneg alen sis = solifera is the extreme wet form ; typical 

 t T. senegalensis having the markings below very indistinct, 

 | whereas in T. solifera they are well denned : this difference, 

 | however, is common as a variation in the genus. 



T. orientis = ButIeri is a less heavily bordered intermediate 

 form, and T. Usmuata the dry form, which, however, we have 

 hitherto only received from Eastern Africa. 



32. Terias brenda. 



Terias brenda, Doubleday, Gen. Diurn. Lep. pi. ix. fig. 6 (1847). 

 Sierra Leone to the Gaboon on the west and the Albert 

 Nyanza to Tanganyika on the east. 



This species resembles the preceding in pattern in all its 

 forms excepting that the secondaries are less frequently
