8. Hyposcritia montana. 

 Appias montanus, Rothschild, Nov. Zool. iii. p. 325 (1896). 



Philippines. 



I have not seen this species, but it is said to be related to 

 11. phoebe. 



9. Hyposcritia (?) ambigua. 



Appias ambigua, Grose-Smith, Nov. Zool. ii. p. 76 (1895). 



Wetter, Dili, and Gilolo. 



Judging from the description, I imagine that this must be 

 a Hyposcritia ; but no hint of its affinities is given. 



10. Hyposcritia phosbe. 



Pieris phoebe, Felder, Wien. ent. Monatschr. v. p. 299 (1861); Reise 

 der Nov., Lep. ii. p. 163, pi. xxv. fig. 5 (1865). 



Philippines. 



Not in the Museum collection. 



11. Hyposcritia lagela. 

 Catophaga lagela, F. Moore, P. Z. S. 1878, p. 838. 

 Tenasserim. Type, B. M. 



12. Hyposcritia lalage. 



Pieris lalage, Doubledav in Gray's Zool. Misc. p. 76 (1842) ; Doubleday 

 and He-vvitson, Gen. Diurn. Lep. pi. vi. fig. 5 (1847). 



Pieris durvasa, Moore, Cat. Lep. E. I. C. i. p. 73 (1857) ; P. Z. S. 1857, 

 p. 103, pi. xliv. fig. 6.

Ilyjjoscritia arqyridina, Butler, Ann. & Mag. Nat. Hist. ser. 5, vol. xvi. 

 p. 340 (1885).' 



N.E. India to E. Pegu. ? , type, B. M. 



H. durvasa is the extreme v\ et-season form of the species ; 

 II. lalage (typical) is also a wet-season phase, probably 

 appearing at the end of the rains ; H. pseudolalage is a smaller 

 form, probably occurring at the commencement of the dry 

 season ; and 77. argyridina is a true dry-season phase. 



13. Hyposcritia indroides. 



Pieris indroides, Honrath, Berl. ent. Zeitschr. xxxiii. p. 403 (1889). 



Perak. 



Not in the Museum collection. Weymersays that it is the 

 H. lalassis of Grose-Smith, but I cannot agree with him.
