BUTTERFLY. 211 



P. CratcKgi or the Hawthorn Butterfly is nearly 

 of the size of the common cabbage butterfly, 

 and is of a white colour, with black fibres on the 

 wings, and is seen in the months of June and 

 July. 



Of the longer winged Hdicoml the P. Ricini is 

 a good example: it is black, with two yellowish, 

 obliquely-transverse bands on the upper wings^ 

 while the lower are deeply bordered with black. 

 It is a native of South- America. 



Of the division entitled Danai Candidi the com- 

 mon large white Butterfly, or P. Brassicce is a 

 familiar example: this insect is too well known to 

 require particular description, and it may be only 

 necessary to remind the reader that it proceeds 

 from a yellowish caterpillar freckled with blueish 

 and black spots, and which changes during the 

 autumn into a yellowish grey chrysalis, affixed in 

 a perpendicular direction to some wall, tree, or 

 other object, some filaments being drawn across 

 the thorax in order the more conveniently to 

 secure its position. The fly appears in May and 

 June, and is seen through all the summer. 



The term Candidi in this division, being applied 

 only in a general sense, it of course contains some

species of a different colour: among these one of 

 the most elegant is the P. Rhamni or Buckthorn 

 Butterfly, of a bright sulphur-colour, with sharp- 

 cornered wings marked by a small orange spot in 

 the middle of each. It is not uncommon during 

 spring and autumn. 



P. Hyak or the Fern Butterfly is also in this
