RHOPALOCERA MALAYAN A. 



family Bumamed CalUdryas* — are sometimes seized with a maoia for migrating to tHe far 

 West. .... I have stood near one of the parade-grounds at Poena, and watched them, 

 with scarce a pause to rest their wings or sip a flower, from eight or nine o'clock Tin til the 

 afternoon t as far as eye could reach, the host kept streaming past t like the fugitive Gauls 

 after one of Caesar's great battles." t 



These interesting facts could be multiplied if our space permitted, and the only reason 

 why they have been thus somewhat amply recorded, is to show, what an interesting, and 

 phenomenal phase of butterfly existence, still requires a scientific explanation 



In my treatment of the ueuration of these Pierince, I am not altogether in nnison with the 

 views of my contemporaries Messrs. Butler and Moore, who also differ somewhat in this respect 

 from one another. I only recognise a discoidal nervate, as such, when its basal emergence is 

 distinctly traced from some portion of the end of the cell. Mr. Butler has a contrary opinion, and 

 treats as a discoidal nervule what I consider as a lower subcostal nervule. The genus Delias 

 affords a good example. In this genus Mr. Butler counts three subcostal nervule s ; \ I enumerate 

 four, the difference being due to a divergence of view as to what is really a discoidal nervule. 

 Here I am supported by Mr, Moore, whose view, however, of this nervule is somewhat capricious, 

 as in Hebomoia he describes five subcostal nervules, § wliilst Mr, Butler and myself can see 

 but four.

|| Goti. nov, type Ficria cy?tia, Ho wits* Mr* Butlor (Cist. Ent. vol. i. p* 49, 1870) gave this species as the type of his 

 genus Phriaura. He subsequently (Trans. Ent. Soc. 1871, p. 1711 stated tbat tliis was an error, and that the species '* agrees 

 in vt-uutioii. atiil in every other character, witb the species of the genus Behnois." But tho type of Bclenoix* as given by 

 Mr. Eutler himself (Cist, Ent, vol. i. p. 34i, is the Pajrilia Ctilypto, Dm., a species in which tho first subcostal nervule in more 

 or loss anastomosed with the costal nervure* a character not applicable to Pi cynis, and I have therefore been compelled to 

 erect a new genus for its reception.
