Mr. E. Doubleday on some new species of Butterflies. 421 



Genus Pieris. 



Pi. Mar ana. Alis omnibus supra albis, raarginibus late nigris, sub- 

 tus nigro-brunneis anticis fascia obliqua, margine interiori late 

 albis, posticis vittis duabus latis albis, duabusque angustis runs. 

 Exp. alar. 2 unc. 



Above. — Male with the anterior wings white, the outer margin 

 with a broad dentate black border, the costa narrowly black ; 

 posterior wings white, with a black border of nearly uniform 

 width, not distinctly defined. 



Below. — The anterior wings fuscous, with a large white patch 

 occupying nearly the whole of the inner margin and extending 

 into the cell. Immediately beyond the cell is an oblique white 

 band commencing close to the costa and terminating in a point 

 near the middle of the outer margin. Posterior wings fuscous, 

 the base occupied by a broad white band ; a similar band com- 

 mences on the inner margin about the middle and terminates in 

 a point without reaching the outer" angle. This band is preceded 

 by a ferruginous streak extending from the inner margin across 

 the discoidal cell, and on the costa at the base is a streak of the 

 same colour. . . 



Female above fuscous, the markings nearly as on the lower 

 surface of the male, but the red streaks are wanting, and the 

 black of the outer margin extends more along the inner margin 

 of the anterior wings, and the white bands of the posterior are 

 rather narrower. The under surface resembles the upper, but is 

 rather paler, and has the same red streaks as in the male, with the 

 addition of a red cloud at the inner and outer angles. 



Head, thorax and abdomen above black, below whitish. 



From the west coast of America, probably Guayaquil. Closely 

 allied to P. Amathonte, but much smaller. 



Pi. Chione. Alis omnibus supra margaritaceo-albis, anticarum apice 

 fusco, subtus anticis margaritaceo-albis, posticis flavescentibus, 

 omnibus margine exteriori flavo corticinoque vario. 



Above of a beautiful pearly-white, the apex of the anterior 

 wings narrowly fuscous, the apex of the posterior with two fus- 

 cous spots. 



Below.— The anterior wings are pearly-white, the base and 

 costa slightly tinted with yellow, the outer margin varied with 

 yellow light ground and pearl-coloured clouds. Posterior wings 

 very pale yellow, with a black streak on the disco-cellular nervure, 

 the margin broadly clouded with the same colour as that of the 

 anterior wings, the brown extending nearly to the cell. 



Head, thorax and abdomen white. 



From Sierra Leone. Closely allied to P. Pharis.
