HiPPARCHiA Galathea. Marhlcd White, The colours 

 of this pretty Butterfly are black and greenish-white, in 

 almost equal proportions; the upper wings have a large 

 oval spot of the light colour near the base, and others, 

 divided by the nervures, in the middle, two small ones near 

 the anterior angle, and a series of spots parallel to the 

 margin ; the lower wings are variegated in a similar manner, 

 and have a row of triangular marks on the hinder margin ; 

 the under side is much paler than the upper, the light 

 colour greatly predominating; there is also an irregular 

 row of ocelli on the inferior wings near the edge, and an 

 ocellus near the tip of the superior pair. These markings 

 vary in form and colour; sometimes the black predomi- 

 nates, and in other specimens the light colour, but not so 

 greatly as to prevent the insect being known. The cater- 

 pillar is yellowish-green, with a dark line on the back, and 

 another on each side; the head is brown, and there are 

 two small spines of the same colour on the hinder extremity; 

 it is found in May on the Fhleum pratense, or cat^s-tail
