Mr. Roland Trimen on some 
of a dwarf sugar-bush, near Salisbury, and in tbat 
position is well concealed by tlie similar colouring of the 
underside of his wings. 
The extreme dissimilarity in the females of two such 
similar males as those of G. alphseus and C. disjunctus is 
a most noteworthy phenomenon, and I do not recall 
another instance in the family Lycaenidse ; although the 
converse case — that of very similar females of nearly- 
alhed species having strikingly dissimilar males — is not 
rare. One is inclined to suspect that mimicry has come 
into play in the case of the ? C. disjunctus.

Closely allied to I. aphnseoides, Trim. 
Pale blue; apical half of forewing blach ; cilia of forewing 
fuscous except at posterior angle where they are white, of hind- 
wing wholly white. Forewing : costa evenly and rather widely 
bordered with black to extremity of discoidal cell ; apical black 
area extending from extremity of cell to apex and obliquely to a 
point at posterior angle, its inner edge irregular ; sexual tuft of 
bristles on inner margin near base, black. Hindwing : a narrow 
black edging from costa beyond middle, becoming linear and more 
sharply defined, and inwardly bordered by a white line, on hind- 
margin from 3rd median nervule to anal angle ; two well-marked 
rounded hindmarginal black spots, one above, the other below, 1st 
median nervule, the lower spot internally edged by an indistinct 
yellowish lunule ; a third black spot on anal angular lobe, ringed 
with a few greenish-silvery scales ; basi-costal sexual patch better 
defined than in aphnoioides, glistening-grey in a darker ring. 
TJNDEFSiDE.— White^with narroiv red transverse streaks; a suhmarginal 
row of small black spots as in aphnceoides. Forewing : an orange-red 
edging from base to posterior angle, linear on costa, but somewhat 
wider on hindmargin ; a very short red streak in discoidal cell near 
basCj and a longer one marking extremity of cell ; beyond middle 
a rather oblique streak from costa to between 1st and 2nd median 
nervules ; 7 spots in submarginal series, all very small except the 
two last, which are about twice the size of the rest- and situate 
between lat median nervule and submedian nervure ; a large basi-
