156 CHARAXES JASIUS. 



singularly armed with four vertical yellow horns 

 tipped with red, of which the two intermediate are 

 the longest. A yellow line passes along each side ol 

 the body in the region of the stigmata, and the back 

 is marked with four indistinct orange spots. The 

 true feet are black, the membranous ones green. It 

 feeds on the leaves of the strawberry tree, and nevei 

 eats except during the night. Its habits are very 

 lethargic. During day-light it remains fixed and 

 motionless on its favourite plant, which it resembles 

 in colour, and thus escapes observation. The chry- 

 salis is smooth, thick, carinated, and of a coriaceous 

 texture, the colour pale green. Two broods or flights 

 of the perfect insect are produced each year, the 

 first in June, the second in September. The cater- 

 pillars of the autumnal brood survive the winter, and 

 are not transformed into chrysalids till the ensuing 

 May. The perfect insects are then produced in 

 about fifteen days. These speedily deposit their 

 eggs, which are hatched in June, and after three 

 months occupied in the usual transformations, the 

 second flight appears in September, and continues 

 the race in the manner above mentioned. In many 

 parts of France the butterfly is named the Packa 

 with two Tails* "
