The Pupa. 



The full grown larva enters the soil and pupates, as de- 

 scribed for the two preceding species. 



Description. The pupa shows the characteristics of the 

 future adult, antennae, mouth parts and wings showing very 

 distinctly. A circlet of spines surmounts the head and pro- 

 thorax, while the abdominal margins bear short hairs, which are 

 more numerous on the last segment. 



Color, entire body, light yellow. Eyes, brown. 



Length, 3.87 m.m.— 3.91 m.m. Width 2.07 m.m.— 2.16 m.m. 



The Adult. 



The habits of the adult are identical with those of the pre- 

 ceding species. After feeding for a few weeks it enters the soil, 

 rubbish, etc., and hibernates.
