that it was named the Bath White, from a piece of needle-work executed at Bath by a young lady, from a 
specimen of this insect said to have been taken near that city. Mr. Haworth, in his Lepidoptera Britannica, 
(pref. p. xxvi.) states, that it had been taken in the preceding June (uot May as mentioned by Stephens) in 
White Wood, near Gamlingay, Cambridgeshire. Mr. Stephens captured it on the 14th August 1818, in the 
meadow behind Dover Castle, where other specimens have since been captured (Entomol. Mag. iii, 409). 
According to Mr. Dale, a specimen was also taken about the same time near Bristol. 
Our recent English entomologists have been singularly unfortunate in respect to the generic relations of this 
insect. Mr. Curtis first proposed forming it and P. Cardamines, L., into a section of the genus Pontia, having 
the wings variegated beneath, and the terminal point of the palpi shorter than the second. Subsequently, 
Mr. Stephens, although noticing Mr. Kirby’s observations on the peculiarity of the metamorphosis of 
P. Cardamines, adopted this section under the name Mancipium—Hubner. In none of his characters of the 
section, however, except the trivial one of the variegated under surface of the wings, is there any agreement 
between P. Daplidice and Cardamines. The labial palpi in a female of Daplidice which I have dissected, 
have the second and third joints of equal length, although Savigny and Curtis figure the third as scarcely more 
than half the length of the second ; the anterior wings of the female Daplidice are not rounder than those of 
P. Napi, whilst we have seen that they are much more acute in the males. At the same time, the character 
of the transformations of the two species is totally distinct (see Plate VI., those of P. Daplidice agreeing with the 
rest of the genus). Moreover, the antenne in Daplidice are terminated by a suddenly formed flat club, which is even 
broader than in P. Napi, whilst in P. Cardamines the club is long, and gradually formed; and lastly, the veins 
of the fore wings * are arranged as in Pieris Napi, differing from those of P. Cardamines.

This genus is closely allied to Pieris in many respects, but differs in others, which are considered as of primary 
importance ; the palpi are especially distinct, the second joint being very long and the third very minute, not 
being more than one-fourth of the length of the preceding {. The antennz are short, and terminated by a 
gradually formed oval compressed club ; the fore-wings are much more dilated and rounded at the tips, and in 
order to support this increased expanse, the third branch of the postcostal vein emits from its upper side two 
distinct veins§. The under wings form a slight channel for the abdomen. The wings are somewhat transparent, 
so as to show the markings of the under side when viewed from above. They are generally ornamented with a 
bright orange spot at the tip in one or both sexes, and on one or both of their surfaces. 
* In the specimens of P. Daplidice, the wings of which I have examined and denuded of scales, the third branch of the postcostal nerve is 
destitute of the short branch emitted (not omitted, as misprinted in p. 19, line 6) close to the apex of the fore wing in the other species of 
Pieris ; but the position of this little branch varies in the different species of Pieris, and it is sometimes even wanting, as I have more recently 
discovered ; indeed, I possess specimens, one fore wing of which possesses this short branch, and the other wants it. Typically speaking, however, 
it is the character of Pieris. 
+ Derived from the Greek et very, and xAo7 the green herb, in allusion to the spotted green wings. 
} Boisduval describes the last joint of the palpi as ‘*& peine aussi long que le précédent.’’—(Hist. Nat. Lep. 1, 556.) But my description 
is taken from a carefully dissected specimen of E,. Cardamines. 
§ Boisduval figures Anthocharis Antevippe (Hist. Nat. Lep. pl. 18, fig. 8.) with only one vein from this third branch, as in Pieris.
