Ixvi NATURAL HISTORY. 



and ornamented with seven large yellow spots in the superior, and six in the inferior, 

 which are, excepting these spots, entirely freckled with black, and have a greenish 

 tinge ; the underside is darker and brighter than in the male, the inferior wings and the 

 freckled parts of the superior are green, parallel to the posterior margin is a line of sub- 

 trigonate spots, very distinct and black in the superior, and reddish-brown in the 

 inferior wings. 



A small specimen of the male, I observe, has indistinct yellow spots on the fimbria 

 of the superior wings, and the castaneous comet-shaped spots on the underside of the 

 inferior are very small, and in one female the black spot in the upper, and the orange 

 spots in the inferior wings are very large, and in another female the upperside very 

 much resembles the male. 



At the request of Commander Ross, I have named this handsome insect after Felix 

 Booth, Esq., the munificent patron of the Expedition. 



11. Chione. Male, yellow, superior wings orange on the disc, with an orange 

 spot near the centre of all the wings. Female ? with the nervures and a spot near the 

 disc black, with a broad black fimbria spotted yellow.

Mate similar to C. Boothii, but the spot at the apex of the discoidal cell is orange, 

 and the posterior margins of the wings are very slightly freckled with black ; the under- 

 side in some examples resembles the female rather than the male of the same species. 



Female, greenish sulphur, superior wings slightly orange on the disc, with the ner- 

 vures and a lunulate spot black, a broad black fimbria bearing six or seven small sul- 

 phureous spots ; inferior with a similar fimbria, but less perfect, and an orange spot on 

 the disc ; underside pale greenish sulphur, similar to C. Boothii, but having only one 

 comet-shaped spot on the under wings. 



Knowing how variable some species of the genus Colias are,* I have great doubts if 

 this be any more than a variety of C. Boothii. There are other specimens, which 

 I believe are varieties of the female occasioned by age and other circumstances, being 

 much paler, with the black of the nervures very much suffused, so much so in one 

 specimen, as to render nearly the whole of the superior wings of the same colour 

 as the fimbria. 



" These butterflies generally appear about the middle of July, as well as the two 



• I need only instance P. Elec/ra Linn. (C. EJttsa Fab.), which is of a deep orange colour, yet the 

 female is sometimes met with of a pale yellow, and during my visit to the south of France, I took one of 

 these females paired with a male of the usual orange colour
