LEPIDOPTERA HETEROCERA. 1367 



Female. Very closely allied to P. delineata, but differing from 

 that species in the following characters. Palpi much paler. Fore 

 wings without distinct bands ; middle pale space broader, approaching 

 nearer to the base of the wing, containing a single undulating and 

 dentate line instead of the two much more straight lines, which it 

 includes in P. delineata ; exterior line much more bent. Hind 

 wings much paler and without lines, excepting an undulating exte- 

 rior brown line and a broad brown border. Wings beneath with 

 the submarginal band much less regular. Length of the body 5 

 lines; of the wings 16 lines.
