BUTTERFLIES OF TRAVANCORE. 445 



border, the underside is of a greenish-pearly-white, the hindwing is 

 immaculate ; it is also said to he smaller than N. ceylonica. Male, 2$ : 

 female, 2§. N. ceylonica is described as having the underside nacreous- 

 blue : {brewing with the costa and apical margin dusky cyaneous, the 

 veins from hase to near their end black, the median brauches crossed by 

 a confluent black streak: hindwing with a marginal row of very in- 

 distinct white spots with dusky borders- Expanse — male, 2g ; female, 

 3 inches. 



The Travancore specimens agree with N. fraterna in having a narrow black 

 border; the underside of some may he described as greetiish-pearly-white, 

 of others as nacreous-blue. 



They agree with N. ceylonica in having the underside costa and apical 

 margin of forewing dusky cyaneous, but the median branches are not 

 crossed by a confluent black streak. The hindwing is not immaculate, 

 but has a row of more or less distinct white spots with dusky borders. 

 Their size varies from 2h, to 3 inches in the male, the female 2J to 3 

 inches. Whether they should he called N. ceylonica or A r . fraterna, or 

 whether these two are distinct species, it is beyond me to decide. 



164. Nepheronia pingasa, Moore. 



Not uncommon in the hills, 1,000 to 3,000 ft. 

 105. Nepheronia gcea, Felder. 



Rare; two males and one female taken near Trevandrum. 



The females of these two species can be readily discriminated, as that of the 

 latter has the discoidal cell in the hindwing and the submedian inter- 

 space for two-thirds of its length yellow on the upper side. There are two 

 types of male, one of which has a very broad black marginal border, the 

 underside white with a bluish tinge, and the veins broadly brown ; both 

 wings have a dusky brown border, with a marginal row of distinct bluish 

 spots. This I take to be N. gcea. 



The other has the underside white with a yellowish tinge, the veins on the 

 hindwing are very narrowly marked, the marginal spots on the hindwing 

 are indistinct, and there are none on the forewing. Except that it is 

 not nacreous-blue, the underside answers to the description of that of 

 N. ceylonica exactly. 



This is the Nepheronia that is fairly common on the hills. 



166. Delias eucharis, Drury. 



Very common in the low country and up to 3,000 ft. on the hills. 



Subfamily Papilionin^e. 



167. Papilio (Omithoptera) minos, Cramer. 



Fairly common in the low country, and up to 4,000 ft. on the hills. 1 



168. Papilio (Pathysa) antiphates, Cramer. 



Rare. I have onlv taken two specimens in open forest at the foot of the 

 Ashambu hills in August, 1379. Mr. Garrett took some near Ariankavu.
