234 Lionel de Niceville — On the Life-History of [No. 2, 



British Museum for his inspection, he admitted that they are that species. 

 This name, therefore, falls. — Leaving the confused and disputed question 

 of the synonymy of this species, I will proceed to give the results of my 

 experiments in breeding it. 



On September 10th, Captain Sage sent me a tin box vrith net cover 

 containing several females of Y. pMlomela. The insects had laid numer- 

 ous eggs on the net, which differ considerably in colour from those of Y. 

 huebneri, being at once distinguishable by the naked eye. On September 

 14th, two larvae emerged. On September 18th, eighteen more emerged, 

 and I placed all the young caterpillars in a stoppered glass jar on the 

 same grass as that which was used for Y. huehneri. The larvae are at first 

 exceedingly small, pinkish- white in colour, hairy, and with a pinkish 

 head. When full-grown, they are a full inch in length, rather larger 

 therefore than Y. huehneri, with the body more compressed than in 

 that species and flattened to a ridge line below the spiracles, the head 

 rounded, the second segment a little larger than the head, the third 

 and fourth segments gradually increasing to the fifth, then very 

 gradually decreasing to the anal segment, which is furnished with two 

 very small immovable pointed processes or tails. The larva is reddish- 

 ochreous coloured throughout, not green as in Y. huehneri , with an 

 indistinct darker dorsal line, two narrow subdorsal ones, and several 

 other very narrow lines placed very close together in the spiracular 

 region above the lateral ridge. There is also a subdorsal series of 

 about eight short oblique streaks. The head and body throughout 

 are shagreened, being covered with small tubercles bearing very fine 

 short hairs. The pupa is either pale ochreous with darker ochreous 

 and brown markings, or pale green with dark brown markings. It is 

 very narrow, the thorax longitudinally humped above, with another 

 ridge just before the abdominal segments placed transversely. On Oct. 

 8th, one larva ; on Oct. 9th, seven larvae ; on Oct. 10th, two larvae ; and 

 on Oct. 11th, one larva changed to a pupa. On Oct. 17th, three females 

 emerged ; on Oct. 19th, two males and one female ; on Oct. 23rd, two 

 females, and on Oct. 24th, one female emerged ; and two larvae died. All 

 these butterflies proved to be true Y. philomela like their female parent. 



On my return from Darjiling on November 8th, Captain Sage gave 

 me eight very small larvje which had emerged on November 4th from 

 eggs laid by a female Y. philomela on October 29th. On December 16th, 

 one larva changed to a pupa, which disclosed a male imago on January 

 5th ; on December 18th, a larva changed, a female imago emerging on 

 January 10th ; on December 24th, a larva changed to a pupa, a female 

 emerging on January 16th ; and on December 28th, two larvae changed 

 to pupee, a female emerging on January 19th from the one, and a male
