of a most beautiful and delicate tint. The bind wings have 
the ground colour of the same tint of green, with white spots 
arranged much as in P. Dapliclicc, hut longer and narrower ; 
this latter character applies especially to the marginal spots, 
which, instead of being roundish or trapezoid, are decidedly 
oblong. PI. VII., 2. 
Time of Appearance. — July. 
Habitat. — South-Eastern Europe and West Central Asia ; 
that is to say, the Steppes of South Russia, Turkey (Staudinger), 
Siberia and Persia. 
This insect, which clearly belongs to the Siberian sub-region, 
seems to be rather rare in collections. 
I have not met with any description of the larva or of its 
food-plant. 
Genus 3.— EUCHLOE, Hub. (1816). 
Anthocharis, Boisd. Sp. Gen. i. 556. 
PiERis, Lat. 
Pontia, Fab. (1836). 
Rather small butterflies. Wings rounded, and either white in 
both sexes, or yellow tipped with orange in the male and with white 
in the female. The hind wings ornamented on the under side with 
a mottled pattern of green or yellow. The head and eyes are of 
moderate size. The antennae shorter than in the genus Plcris, 
with flattened ovoid clubs. The abdomen is slender, and of the 
same length as, or a little shorter than, the hind wings. 
The Larvae are small and downy, tapering towards the 
extremity, and, like those of Pieris, feed on Gruciferce. 
The Pupae are arched and boat-shaped, differing much in 
shape from those of Pieris, but attached in the same way. 
The species of this genus have very much the same habits as 
those of Pieris, to which genus Eucliloe is very close. This genus 
is tolerably well represented in Europe, and is confined to the 
North Temperate regions of both Hemispheres. All the inter- 
tropical species that used to be included in this genus are now 
placed in the genus Callosune, of which one species, C. Nouna, Luc., 
occurs in Algeria.
