PIERID.E. 
C. JFerdandi, but is somewliat larger. It is probably a southern 
form of that insect. Habitat, S.E. Siberia and the Amur. 
C. Sacjartia, Ld. Hor., 1869, t. iv. 1, 2. — Expands from 2 to 
2-37 in. The male has all the wings of a bluish green colour and 
bordered with black. The fore wings are tinted with yellow towards 
the costa and have yellow spots on the black border, on which also 
the nervures show as yellow stripes. The discoidal spot is large 
and black ; the hind wings have a row of yellow spots internal to 
the black border, and an orange discoidal spot. The head, pro- 
thorax, and antennae are faintly red, as well as the marginal fringes ; 
they are sometimes, however, tinged entirely with green. The 
female is pale greenish white, and has very large spots of the same 
colour on the marginal borders ; the discoidal spot of the hind 
wings is bright orange. The under side is very much like that of 
PJiicomone, but paler. This species is undoubtedly the hand- 
somest of all the light-coloured Coliades, and is found in July 
and August in those regions which lie to the south and east of the 
Caspian Sea. 
C. Boothii, Curtis, ‘ Voyage in search of N.W. Passage’ (Loud. 
1835). — Expands 1-50 in. The fore wings are orange-yellow, 
shading off along the costa and hind margin into light green ; the 
discoidal spot is small and roundish ; the marginal black band is 
very narrow. The hind wings are greenish, with an orange discoidal 
spot and a very narrow hiud-marginal black band. The fringes of all 
the wings are red. This species is found in Arctic America in the 
district known as Boothia Felix, between 70° and 75° N. lat. It is 
quite distinct from C. Heda, with which it has been confounded. 
The extremely narrow unveined black border and the greenish tint 
of the wings are never found in C. Heda, and the discoidal spot in 
the male of the latter species is never rounded. 
C. Aurorina, H.-S. 453. — Expands from 2-25 to 2-50 in. The 
male has all the wings of a dull reddish orange, with black border, 
like that of Edasa, with distinct orange veins. The hind wings 
are greenish in the inner margin and have a very large and bright 
orange discoidal spot. The female has the border spotted as in 
Edusa, and the ground colour of the wings is purer than in the 
male, owing to the absence of the minute black scales with which 
the wiugs of the latter are covered. Both sexes have puiqjle
