OBSERVATION. It is a good plan when eggs of any 

 given species are desired, to watch the parent female 

 as she flies hither and thither, depositing ova. 



The portion of the plant on which the eggs are laid, 

 can thus be easily secured. 



Another plan, is to incarcerate an impregnated 

 female in a darkened box, but which partially admits 

 the rays of the sun. The interior can be loosely lined 

 with leno or tissue paper, on which the insect can 

 deposit her eggs, which can then be clipped off, if 

 desired. 



It is best to regale the insect thus imprisoned, with 

 a sirup of sugar and water, once or twice daily. When 

 the butterfly is required to partake of this fare, place 

 the nectar before it, and blow her gently in its direc- 

 tion, when she will immediately unfold her proboscis 

 and feed. Of course, when the female has deposited 

 her complete stock of eggs or as many as are wanted, 

 she can then be allowed to escape into the air, again. 



I have always found this plan to succeed perfectly. 

 This system, of course, applies to all species ; though 

 some are more difficult of treatment than others. 



LARVA. On Ononis spinosa, Genista, Grass and 

 Clover, especially the former of these, in April, July 

 and August. 



VARIETIES, &c., v. Icarinus. 



HABITAT. Same localities as the type. 



There is also a beautiful aberration of the $, in 

 which all the wings are suffused with the blue of the 

 /, thus answering to the tar. Ceronus of L. Bellargus. 



HABITAT. Same as the type. It has been found, 

 among other places, in the Vallon Obscur, Nice; and
