two occasions, bufc been unable to capture ; one of the N. cenfaurus group,

Family PAPILIONID^. 



Subfamily Pierin^. 



157. Leptosia xiphia, Fabricius. 

 1000—7000 ft. 



158. Terias hecabe, Linnaeus. 

 Form hecaheoides, Menetries. 



„ cesiope, Menetries. 



„ purrea, Moore. 



,, excavata, Moore. 



,, silhetana, Wallace. 



,, uniformis, Moore. 



„ swinhoei, Butler. 

 T. silhetana, unifonnis, and swinhoei possibly form one distinct spe- 

 cies. The forms hecaheoides and cesiope were described from the West 

 Indies, and it seems scarcely probable they are Indian. 



159. Terias ltbythea, Fabricius. 

 Form drona, Horsfield. 



„ rubella, Wallace. 

 ,, venata, Moore. 

 „ rama, Moore. 

 T. venata and rama probably form a distinct species. 



160. Terias ljita, Boisduval. 



161. Catopsilia catilla, Cramer. 



162. Catopsilia crocale, Cramer. 



These two species are doubtfully distinct, and there are several 

 intermediate named forms. 



163. Catopsilia gnoma, Fabricias. 

 Form ilea, Fabricius. 



164. Catopsilia ptranthe, Fabricius. 



These two species again are doubtfully distinct. G. ilea is inter- 

 mediate. 



165. IxiAS pyrene, Linnaeus. 



166. IxiAS pyrenassa, Wallace. 

 Form dharmsalce, Butler. 



The former is the wet-season brood, the latter the dry-season form. 



167. IxiAS meridionalis, Swinhoe. 

 Form anubala, Swinhoe. 



The former is the dry-season form, the latter the wet-season form.
