Ixxii NATURAL HISTORY. 



the thighs, and underside of wings vermihon, variegated with the ochre and brown of 

 the upper surface. 



On the 8th of August, this splendid moth was brought on board by one of the men, 

 it was the only one seen, and too much inj ured for drawing. In a former voyage 

 a similar insect was brought home by Captain Lyon, this may therefore be only 

 a remarkable variety.

1 have named this very distinct moth after Dr. Richardson, the friend and companion 

 of Sir John Franklin. 



Two males only were brought home, they were captured on the 25th of July, 

 1830, and it was by no means a numerous species. It considerably resembles tlie 

 Noctua Lappo of Godart, but is at once distinguished by the white on the under wings, 

 and it is worthy of remark, that the only specimen I have seen of that moth was 

 captured in Forfarshire, Scotland, and presented to me by Charles Lyell, Esq.
