upwards into a loop like the caterpillars of Geometra 

 and Catocala. Before undergoing its metamorpho- 

 ses, it attaches itself by the tail and a band round 

 the middle, like the caterpillars of Papilio, Colias, 

 Pieris, &c, or rather like those of Geometra peri- 

 ocular ia and Gyrarla. 



" The chrysalis is elongated and pointed, scarcely 

 angular, of a green colour with a transverse gilded 

 band ; the extremity, which is of a deeper green, is 

 sprinkled with a great number of golden points. 



" The perfect insect comes out in about three 

 weeks. Exposed to the sun, it developes itself 

 completely in two or three hours, while individuals 

 born in the shade take nearly a day to develope 

 themselves, and are usually less brilliant."
