LEPIDOPTERA. 139 



metamorphosis of Lepidoptera, in which they noticed the pecuharities that distinguish this group from 

 the Whites. The name of Danai Jlavi, in our nomenclature clouded Yelloivs, was accordingly assigned 

 to the family of Pallidiventres ( Seitenstreifraupen) , which, as has been shown in the introduction, p. 14, 

 is the representative of the genus Colias. As science advanced, further subdivisions became necessary. 

 Mr. Swainson noticed the peculiarities of the Papilio Hecabe of Linnaeus, and from it and its associates 

 defined the genus Terias: and both Mr. Curtis and Mr. Stephens agree in confirming the distinctness 

 of the genus Leucophasia, of which Pontia Sinapis is the type. The observations which will be made in the ,, 

 sequel, will clearly show the ground on which the genus Pieris rests. After all these subdivisions, the genus 

 Pontia, as now defined, does not consist of an assemblage of uniform species ; in the limited Indian series 

 contained in our collection. Jive distinct types of form are comprised, on which as many sectional distinc- 

 tions are founded. The characters of the sections are chiefly derived from the modifications of the antennae, 

 palpi and outline of the wings. The metamorphosis, as far as its more minute modifications have 

 hitherto been discovered, has also been consulted ; and the pupa affords a very clear discrimination, 

 in two of the sections. The peculiarities of the nervures of the wings confirm, as far as I have yet observed, 

 the subdivisions now proposed, but I have not been enabled to follow this character into more minute varia- 

 tions, by a comparison of all the species in our own collection, which thus remains for a future enterprize. 

 Each of the sections is designated by a proper name derived from the typical species, which will provisionally 

 characterize the group as a patron3niiic, until the further accumulation of species shall indicate the 

 necessity of raising the sections to the rank of subgenera.

Wings above, in the male, greenish or bluish white, with a common posterior border, the costal 

 border of the fore wings and the nervures of a black colour; in the female grayish white or 

 yellowish, with broader borders along the margins generally, which spread to the disk and 

 assume a blackish-brown tint, the nervures being throughout more diffuse ; this sex bears 

 near the hinder margin and parallel with it a regular series of white dots, extending through 

 both pair, and within the same, tending towards the disk, a less regular series of oblong 

 longitudinal spots of different sizes, of the same colour: underneath the wings are cream- 

 coloured with a glaucous gloss in the male, and marked with delicate black nervures, while 

 the posterior border of the fore-wings appears only in a strong light, the wings bearing 

 towards the margin at the nervures clouds of obsolete brownish irrorations ; in the female 

 the wings are grayish brown with a faint violet lustre ; the fore-wings having a more, satu- 

 rated tint near the base, the hinder being grayish yellow, while in all the wings the nervur^ 

 are broader and the dots and spots of the upper surface are distinctly apparent.
