narrower than those of the latter, and are magnificently orna- 

 mented with blue crescent- shaped spots and an orange-coloured 

 eye bordered below with blue. This beautiful species is not rare 

 at Montmorency, at He- Adam, and at St. Germain. It is said to

 tail, but its capture is considered as very questionable. It 

 appears for the first time at the end of April, and for the second

in July and August. The Parnassius Apollo (Fig. 143) is a 

 beautiful butterfly which appears in June and July, and is found 

 commonly enough in the Alps, the Pyrenees, and the Cevennes. 

 Its wings are of a yellowish white. The upper part of the fore 

 wings presents five nearly round black spots; the base and the 

 costa or front edge of these wings are sprinkled with black 

 atoms. The upper part of the hind wings presents two eyes of 

 a vermilion red, the inner border furnished with whitish hairs 

 amply dotted with black, and marked towards the extremity with 

 two black spots. The under part of the fore wings is very 

 similar to the upper. But the under part of the hind wings

 verse band near the base. The body is black, furnished with 

 russety hairs, and the antennae white with the club black. 



The larva of the Apollo lives on saxifrages. To effect its 

 transformation it surrounds itself with a slight network of silk 

 in which are confined one or more leaves. This caterpillar 

 is thick, smooth, cylindrical, and covered with small slightly 

 hairv warts and ornamented on the first ring 1 with a fleshy tentacle
