THE expansion of the wings is from one inch and 

 eight lines to two inches five lines ; it is therefore 

 considerably smaller than the preceding, to which in 

 other respects it bears a strong resemblance. The 

 upper surface is white, slightly inclining to yellow ; 

 the primary wings have a dusky spot at the tip, ex- 

 tending a short way along the anterior border ; in the 

 male there is a single rounded spot on the disk, and 

 two in the female, with an oblong patch behind, as 

 in the same sex of P. Brassica ; the hinder wings 

 with the usual black mark on their anterior border. 

 Beneath, the anterior wings bear two discoidal black 

 spots, the tip is yellow, and the base slightly sprinkled 

 with dusky ; the under wings are rather bright yel- 

 low, with dark scales intermixed, making them ap- 

 pear as if powdered with black dust ; on the anterior 

 edge at the base, there is a narrow streak of orange- 

 yellow.
