Pupa (fig. 5), length 5 mm., pale green or light brown changing to

 various organs, especially the eyes, can be made out. On the dorsal 

 surface is a pair of beautiful white funnel or trumpet-shaped breathing 

 organs. The tail parts are bent round under the head and bear on the 

 last segment a pair of white spatula-shaped " fins '' (figs. 6, 7). 



[The pupa bears a single pair of floats on the dorsal surface of what appears to be 

 the first abdominal segment. Each caudal fin carries a short curling seta at its 

 extremity (fig- 7).— E. E. G.]
