PAPILIONINAi. 55 



Food-plant. — " The larva feeds ou a species of wild Orange, native name 

 eemur. 



Pupa.—" The whole of the front portion (i.e. breast, etc.), pale blaish-green, with 

 a few lines of a darker shade on the wing-coverts, and body, and with a faint medial 

 line. On the back the colouring is of a more yellowish-green, with pale yellow, pale 

 whitish, and brownish dots and markings. Outline of the breast highly arched, and 

 hind margin of wings slightly raised. Sides slightly flattened out, with a hard sharp 

 ridge running longitudinally round the whole insect, usually of a pale brownish 

 colour, but which, in some individuals, is very dark, and in others almost white. 

 This ridge forms a very marked outline, viewed from the front or back, and runs 

 thus: — Head comparatively small, markedly bifid, with the inner portions of the 

 projections distinctly notched ; behind the eyes concave, angling out at the shoulder, 

 from thence somewliat square-cut, and contracting to a sharp notch at the waist, 

 tlirough v/hich the suspending cord passes. From the waist to the end of the 9th 

 segment a considerable curving out takes place (the margin of the ridge of this 

 portion is slightly folded inwards over the Ijack) ; from the Gtli to tlio 13th segment 

 the body rapidly narrows, the whole body thus being somewhat heart-shaped. The 

 thorax is raised and angular, and from its summit runs a pale greyisli line (com- 

 mencing very gradually) bounded on either side with brown to a little beyond the 

 waist (this brown edging ends abruptly in, as it were, two short lines very well defined) 

 in continuation with a broader medio-dorsal line margined on either side with darker 

 green than the ground-colour to the vent ; just below the waist and opposite the 

 terminus of the brown marking above mentioned on either side is a dark somewhat 

 quadrate spot, which varies in different individuals, and in some these spots are 

 absent; about this region there is usually a yellow suffusion; a bright yellow line 

 passes from these spots to the tail, curving outwards to the shape of the body in itii 

 course, and between this line and the medio-dorsal line is aline of yellow dots. The 

 spots on the body seem to vary very much, but their general outline is the same. 

 On the thorax there are usually five dark dots, placed one in the centre below the 

 head, the other four, two on either side of the raised portion of the thorax diverging 

 towards the waist. The spii'acles follow the outline of the ridge, and are situated 

 just along the iimer edge above. The majority of the pupte were green, as described, 

 but a few were of a pale grey colour. The pupa is generally suspended head 

 upwards, one or two assumed the reverse position. Some of the perfect insects 

 emerged in eleven days, others in fifteen and seventeen days from date of changing 

 into pupge." 



Habits op Larva. — " The larva rests on the upper sides of the leaves in the 

 first and second stages, laying out full length, with the first five segments slightly 

 raised ; but in the last stage they seem to pi^efer reposing further in the shrub at the
