ZEGKiS. 



From the observations of M. Graslin and Dr. Rambur on Z. Eupheme, we learn that the Larva, which feeds on 

 Sinapis incana, is yellowish, with a paler lateral line, marked with oblique black streaks, and a series of black dots 

 disposed in groups of three on the sides of each segment. Its growth is very slow ; when arrived at maturity it spins 

 a delicate, silken, net-like web on the stems of the Sinapis ; suspending itself also by a very fine transverse thread, and 

 by the tail. 



The Pupa, which is singularly gibbous, has, like Anthocharis, the abdominal segments immovable. 



The Perfect Insects appear in April, the winter being passed in the pupa state. They fly with great rapidity, 

 and are very difficult to capture. It has been taken by several collectors in Andalusia, and the Tschaptschatschi 

 Mountains, and the original specimen figured by Esper was taken near Sebastopol. 



I regret much that the extreme rarity of this insect has compelled me to trust to Dr. Rambur's figure of the palpi, 

 which, however, is without doubt, accurate. The only specimen which I am aware of in any English collection is the 

 one from which the accompanying figure was taken, which is now in the collection of Mr. Gutch, who obtained it in one 

 of his recent visits to Madrid from Sr. Graells, and immediately placed it at my service for examination. It is less 

 bright in colour than specimens which I have seen in the collections of Dr. Boisduval and M. Pierret. 



The other species of the genus as yet are only known to me by the descriptions and figures of MM. Eversmann 

 and Menetries.
