This again recalls a common condition in V. myrinna and 
V. huntera. 
(3) The appearance of a new red spot on the under- 
side of the forewing, just below the stem of the median 
nervure before bifurcation. ‘This represents a pale patch 
of various shades in V. callirrhoe, V. myrinna, V. hwntera, 
V. cardwi, etc. 
(4) The appearance of another red spot on the under- 
side of the forewing, just below the first median nervule. 
This represents a patch visible on both surfaces of V. 
callirrhoe, and fully developed in all the species nearly 
allied to V. carduwt. 
(5) The tendency towards resolution of the inner 
margin of the red band, as in V. callirrhoe. 
(6) The suffusion of the dark ground colour with 
golden brown, also as in JV. callirrhee. 
Of these, Nos. (1) (2) and (3) are points now 
observed for the first time; while (4) (5) and (6) are 
confirmations of previous results. (See a former paper 
by the author in Trans. Ent. Soc. Lond. 1893, p. 70.) 
B. Cooled. 
(1) Much substitution of lavender or metallic blue- 
green scales for black. This points to the ancestral 
condition seen in the females and parts of the males in 
many species of Argynnis, e.g., A. paphia, var. valesina, 
A. sagana ¢, A. niphe 3 and ¢, and A. diana ¢. 
(2) The presence of minute patches of bluish scales 
near the margin of the dark ground-colour in the hind- 
wing, indicating the blue centres of the almost com- 
pletely merged Series I11.—an ancient feature of Vanessa 
and Grapta. 
(3) The marked increase of marginal blue, especially 
about the anal angle of the hindwing. This appears to 
represent the condition seen in Argynnis niphe, and 
ultimately to point back to the primitive Argynnid 
colouring of A. valesina and A. diana &. 
These are all confirmations of former results.

In this species, warming tends to revive, in the fore- 
wing, a series of dark spots (ID), occurring normally in
