Lrwin,' id. 34. Doiwvun,i v. 0, /;. 21 1. Di/ncaii,l pi. 4, Jig. 1 . 



liiMerflu. Wings yellow and black ; the black being also 

 powdered with yellow. Primary with a row of yellow cres- 

 cents at the posterior margin. Secondary, tailed, indented, 

 with a double row of crescents at the posterior margin, the 

 interior ones blue, the exterior ycUow. Anal angle with an 

 eye-like red spot sunnounted by a blue crescent, and sur- 

 rounded by a black iris. Wings underneath paler, variegated 

 with black and grey, and two or more red spots, one at each 

 of the posterior angles. 



Caterpillar. Smooth, of a lovely pale green above, under- 

 neath shading into a line bottle-blue, striped with black 

 transverse rings or bands, on which are dots of orange red. 

 This specie.s is furnished with a remarkable v-shaped scent- 

 organ, which is situated at the anterior margin at the back 

 of the first segment, close to the head. It secretes an acrid 

 liquor, which emits an unpleasant smell, particularly when 

 the animal is irritated, by whicli it keeps the ichneumons at 

 a distance. At the bottom it is simple, but divides towards 

 the middle into two forks, of a fleshy substance, which it can 

 lengthen as a snail does its horns, to five times their ordinary 

 extent, or retract them within the stalk, .so as wholly to 

 conceal them, leaving only two tawny-coloured dots to nuuk 

 their existence. It is solitary, and feeds principally ou 

 umbelliferous plants. 



Chrysalis. Of a yeUowish gieen and grey, beset with 

 many points of a whitish hue, with a longitudinal black 

 band on each side.
