 brown, while the entire pupa is cream white and remains lo

 legs and antennae assume a reddish brown color, then the 

 head and finally the entire body. The adults at transforma- 

 tion are also of this brownish color, but gradually become 

 darker until after a few da]rs they are of a dull, piceoos black
