and Yellows, (Colias,*) species of which genera, 

 little differing between themselves, are very widely 

 scattered. Butterflies of this division use all the 

 six feet in walking, and their pupce are suspended 

 by a girdle, as well as by a button. 



Through the foreign genera Danais^ and Heli- 

 conius,^. whose prevailing colours are orange-tawny 

 and black, and the latter of which is distinguished 

 by the lengthened oval form of the fore wings, and 

 by being almost destitute of feathery scales, we 

 arrive at those pretty Butterflies called Fritillaries, 

 (Argynnis^ &c.,) marked with black or orange, more 

 or less tesselated or chequered, and frequently orna- 

 mented on the inferior surface by spots and dashes 

 of bright silver, as in our own A. Aglaia,\\ and still 

 more remarkably in a beautiful North American 

 species, A. Vanilla. The Vanessa follow, with 

 notched and variegated wings, whose caterpillars are 

 armed with barbed spines. We have several native 

 species of this genus, such as the Admirable, (V. 

 Atalanta,} banded with scarlet on velvet black ; the 

 beautiful Peacock, (V. Jo,) with its rich eye-spots, 

 and the common Tortoiseshells, (V. Urticce, &c.) A 

 large and richly-coloured tribe is allied to this, 

 (NyinpJialis*^) whose wings are often adorned with 

 a rich purple gloss, visible only in certain lights.
