6 SGABOE SWALLOW-TAIL. 



There was a specimen in Mr. Swainson's cabinet, which he told 

 Donovan was taken by his brother-in-law. Captain Bray: he believed 

 in the Isle of Wight. 



Dr. Abbot took one in the month of May, in Bedfordshire. This 

 specimen is now in Mr. Dale's cabinet, 'in perpetuam rei memoriam.' 



The butterfly appears in May and June. 



The caterpillar feeds on the apple, sloe, plum, peach, and almond. 



The jjerfect insect measures, in different specimens, from three inches 

 to four inches across the wings. The ground-colour is very light 

 cream yellow. The fore wings have two black attenuating streaks near 

 the body, which meet an apparent extension of them on the lower 

 wings; next to these is a very short one, extending only half-way into 

 the wing; this is succeeded by another long one, which reaches quite 

 across the wing, met by a sort of shadow of it on the hind wing, and 

 this again by another short one, extending only one-third across the 

 wing. Again, there is another long one, reaching nearly across the 

 wing, and then lastly, another long one, which completely borders its 

 outside, edged with a narrow yellow line, of the ground-colour of the 

 wing. The hind wings have a_ black border following the crescent- 

 shaped undulations of their outside edge, and divided by four or five 

 streaks of blue of the same shape. At the inside corner of the wing 

 is a black spot, with a blue patch of irregular shape in its centre, 

 and bordered above with red, forming an eye. The wings have long 

 tails; their tips are yellow. 



The under side is paler than the upper, and the black markings 

 less extended. The band on the middle of the hind wings is composed 

 of two narrow black lines, the outer one of which is edged on the 

 inner side with orange. 



The caterpillar is short and thick, especially in the middle, and 

 most so towards the head; narrower towards the tail. It is of a 

 green colour, darkest on the back, and spotted with black, varying to 

 light yellowish, with a faint tinge of red beneath. It has a narrow 

 yellowish stripe along the back, and another along the side, near the 

 legs. On the sides are oblique yellowish lines, dotted with reddish. 

 The head is small. 



The figure is taken from the original specimen mentioned above, now 

 in the cabinet of the Rev. George Rudston Read, of the Rectory, 

 Sutton-upon-Derwent, near Pocklington.
