666 Mr. A. G. Butler' a furtheo^ notes on the 



species this insect was divided into, how little, com- 

 paratively, it varies ; the sexes differ considerably, 

 owing to the obliteration of the white markings in the 

 female, but otherwise there is nothing beyond intensity 

 of colour to account for the manifold synonymy noted 

 above.

This is also P. autumnalis of Eiley.

 This genus differs from Spodoptera in the fact that 

 the antennae of the males are very delicately ciliated, 

 especially towards the base, and in the much greater 

 similarity of the sexes.
