66 BUTTERFLY COLLECTOR'S 



Observation. Tliis is one of tlie earliest of onr vernal 

 Botterflies, and frequently even in the chilly and uncertain 

 months of March and April is to be seen in our shrubberies 

 and gardens, where its beautiful colour and graceful form 

 render it an object of great attraction. The eggs which it 

 deposits in the spring, appear as a second brood of Butter- 

 flies in August ; these somethnes continue dormant tlu'ough 

 the winter. It also hybemates in the pupa .state. The 

 Butterfly is often found on Melica tmiflora (Wood Melic 

 Grass). Mr. Curtis in his elegant work of " British Ento- 

 mology," pi. 173, has figured a beautiful variety of this 

 insect, of a deep clouded yellow, dotted and streaked witli 

 orange, which was taken at Peckham, in Surry, and is now 

 in the cabinet of Mr. Haworth.
