SOME NOTES ON TRANSFORMATIONS OF AUS- 

 TRALIAN LEPIDOPTERA— (Second Paper.) 

 By Henry Edwards. 

 Rhopalocera. 



Pyrameis kershawi. M'Coy. 



Chrysalis. — In life pale greenish yellow, with a golden sheen. 

 The whole surface, particularly of the abdominal segments, 

 minutely roughened, and thickly and deeply punctured. The 

 head, thorax, and wing-cases transversely wrinkled. On the 

 thoracic region are 8 raised tubercular points — 4 lateral, 4 

 dorsal — and on the abdomen is a triple row of such points, the 

 middle one placed anterior to the others, so as to form a triangle. 

 These points are richly tipped with gold. The cremaster is 

 wedge-shaped, truncate. Length, 17 mm. ; width, 6 mm. 



A comparison with this species and Pyr. cardui will show 

 remarkable differences. The raised points on the latter are 

 nearly three times as long as those on P. kershawi, while in 

 cardui, after the emergence of the imago, the chrysalis case is 

 blotched with black, and has no trace of the golden sheen so 

 visible in kershawi. After emergence, the case of kershawi 

 becomes a pale fawn drab, almost transparent, the substance 

 being far more delicate and fragile than that of cardui. In this 

 regard kershawi approaches more closely the allied species 

 Pyr. caryce, Hubn., found on the Pacific Coast of America. 



SPHINGID/E. 



Chcerocampa erotus. Cram. 



Pupa. — Tawny wood- brown, with a- dorsal row of brown-black 

 blotches, and lateral rows of the same enclosing the spiracles. 

 The surface is everywhere rugosely wrinkled, the abdominal 

 region having also deep irregular fovese. The wing-covers are 

 smoother, with rows of black dots marking the course of the 

 nervures. Anal segment with a deep pit beneath. Cremaster 

 small, bifurcate, black. Length, 50 mm. ; width, 15 mm. 



Chcerocampa scrofa. Bois. 



Pupa.—FsLwn drab, much wrinkled, but very glossy in the 

 interspaces, the surface with small brownish blotches, most con- 

 spicuous towards the posterior extremity. Spiracles large, brown. 

 On the wing-covers, which are whitish drab, is a series of inter- 

 rupted brown lines, very distinctly marked, distinguishing the 

 course of the nervures. The cremaster is much produced, long, 

 and narrowed almost into a point. Length, 30 mm. ; width, 

 10 mm. 



ZyGjENID/E. 



Agarista casuarin^e. Don. 



Pupa. — Short, almost ovate in outline, dull brown or pitchy. 

 The wing-cases are broadly developed, and covered with very
