PIERIS NAPI. 21 



this line the black spiracles * are placed, each in a 

 round, rather tumid, deep yellow spot. Below the 

 spiracular line there are sprinkled some greenish- white 

 (or whitish-green) dots with hairs rather longer than 

 those on the back ; the head is of a more yellowish- 

 green than the body and is marked with black above 

 the mouth, the ocelli black ; the head is covered with 

 minute black points and some longer pale hairs. The 

 anterior legs are yellowish-green, the ventral and anal 

 prolegs are the same colour as the belly but semi- 

 transparent. 



The skin of this larva is really shining, as it affords 

 a line of bright light along the body according to the 

 position in which it is viewed, but the numerous points 

 and soft hairs produce the velvety look. The dorsal 

 line is just slightly paler than the ground colour, a 

 very slender thread showing faintly over a rather 

 broader and pulsating one beneath. 



The black points, it may be noted, are of two sizes ; 

 the smaller and more numerous are only to be seen 

 with a powerful lens. 



On the 4th and 5th July these larvae attached them- 

 selves and assumed the pupa state on the 6th and 7th. 

 The perfect insects made their appearance on the 15th 

 and 17th of July, 1874. (W. B., Note-Book II, 79.)

On the 18th August, 1882, I received from Herr 

 Heinrich Disque, of Speyer, thirty-three eggs of this 

 species (along with the dead parent butterfly) laid on 

 the flowers, leaves, and stems of a species of Reseda. 



The egg is laid standing on end and is about the 

 same size and red colour as an anther of the flower of 

 the plant on which it is laid, but can be detected by
