12 THE ENTOMOLOGIST. 



the thorax is marked with triangular streaks of black outlined 

 with orange ; the antenna-cases and wing-nervures are faintly 

 marked with orange-brown, and the wing-covers and eye- and 

 leg-pieces with strong black blotches and dashes." 



All the above remarks, so far as shape, general appearance, 

 and so forth are concerned, refer equally to the pupa of other 

 members of the group. 



The following notes have been made from pupae bred by 

 myself : — 



.-Im'cZia.— Pupa : General appearance very pale blue-grey, 

 with transverse lines of orange, and black dots. Wing-cases 

 darker blue-grey, with a row of very short black lines at the edge, 

 interrupted below the middle and at lower end. Poulton's line 

 distinctly visible. Under a lens the ground colour is seen to be 

 white slightly tinged with blue, with line black reticulations. 

 Spiracles black, surrounded by white, patched with orange-brown. 

 Anal segments recurved ; tendency to pupate suspended (not 

 universal). 



Parthenie. — The pupa is very like aiirelia, but darker, and 

 has the border of black dashes on the wing-cases uninterrupted. 

 The tendency is to pupate under the leaves. 



With regard to the distinction in the markings on the wing- 

 cases of aiirelia and parthenie, it is, I think, reliable. When 

 Mr. Sloper and I were breeding these two species from larvae 

 which we had found, he kept the two species in separate cages ; 

 some of mine were also kept separate, but some were intentionally 

 mixed together. When we carefully examined his pupsG this 

 was the most noticeable distinction, and by this I separated my 

 pupaG, which in every instance bred true. As these larvae only 

 represented one locality for each of the species (Sion and Char- 

 pigny respectively), the distinction may nothe of universal appli- 

 cation, but it seems likely to be constant, judging by this test. 



Var. berisalensis. — Pupa : General appearance dull dark 

 bluish grey with orange tubercles ; wing-cases dark mottled 

 brown, except when too dark to show markings. Under lens : 

 No blue colour as in the other two species {aiirelia and -parthenie), 

 but intersegmental bands of slate-colour, with white and slightly 

 pinkish spots ; orange humps in the positions of the larval 

 spines arranged on black and white spotted transverse bands ; 

 wing-cases of white ground colour, but almost (sometimes en- 

 tirely) covered with brown markings ; anal end recurved, with 

 two scarlet humps (sometimes dull) ; humps on thoracic seg- 

 ments white tipped with orange ; the pupae vary considerably 

 in amount of slate-colour, black and white ; also in dejDth of 

 wing-markings, sometimes having a reddish tinge, sometimes 

 being almost jet-black. The pupae are only very slightly sus- 

 pended.
