Prerts DAPLIDICE (the Green Chequered White) was, till recently, made a separate genus 
(Mancipium), though some British Entomologists have proposed making it form, with 2. Carda- 
mines, a section of the genus Pieris. The alliance with £. Cardamines was opposed ; the green 
mottling of the underside of the hind wings common to both these insects being deemed too 
trivial an affinity to form the basis of a generic relationship, especially when the peculiar form 
and general character of the chrysalis of £. Cardamines was taken into consideration ; but Dapli- 
dice has since been united to the Pierides, leaving LZ. Cardamines to form a separate genus. Upon 
examination, this arrangement will be found tolerably satisfactory, as P. Duplidice exhibits 
many of the typical characters of the Pierides, with which it is more strongly linked by the in- 
termediate species P. Rape, and more especially P. Napi, described in the last Plate. Mr. West- 
wood notices the angularity and slightly indented margin of the anterior wings of the males of 
P. Daplidice, while those of the females are more blunt at the angle, and rounded in the external 
outline, a peculiarity observable also in the male and female of P. Napi. The antenns also of 
that species, in the sudden flattening of the club, strongly resemble those of P. Duplidice. The 
male of P. Duplidice (No. 1) is distinguished from the female (No. 2), by the absence of the 
second black spot on the fore wings. The fine green chequering with which the underside of 
the hind wings is pencilled, and from which the popular designation of this beautiful insect is 
derived, is shown at No. 3. I have taken the Caterpillar (No. 4) described by Boisduval rather 
than that described by Hiihner, as it agrees better with the accounts given of its appearance by 
continental collectors, which we must be content to rely upon till this insect has been discovered 
in the larva state in England, of which at present there is no record. The Chrysalis (No. 5) 
accords pretty closely with those of the other species in the genus Pieris, though it is of some- 
what shorter, thicker, and rounder proportions. The Caterpillar is found on the Continent at 
two seasons, Spring and Autumn, at nearly the same periods as those of the Common ‘ Whites,’ 
and the insect is very common in the south of Europe, though so rare with us. It is said to 
feed on the Wild Mignonette, and also on several cruciferous plants of the Cabbage tribe ; and 
is generally found in dry and sandy situations. With us it is one of the greatest of our Ento- 
mological rarities, for though its capture has occurred in several localities, only single specimens 
have been taken, I have more than once listened to the late Mr. F. Stephens’ interesting ac- 
count of his capture of the famous specimen in his fine Collection, which took place in the 
month of August in the year 1818, in a meadow behind Dover Castle, where another specimen 
has since been taken. White Wood, near Cambridge, is celebrated as one of the localities for 
its capture, and Whittlesea Mere and Worcester have been since added, where single specimens
