is placed beyond the end of the cell, between the 3rd and 
4th sub-costal nervules. 
(5) The irregular spot within the cell. 
The transition from a condition, resembling the female 
parent, in which the five chief spots of the fore-wing are 
white, towards one in which they are buff, is clearly seen 
in the following comparison of the 6 female specimens in 
this synepigonic group. 
I. The largest specimen, unfigured. All five spots 
white except the edges of (1). The buff tint is 
especially pronounced on its inner marginal edge 
—a tendency often manifest in specimens in which 
this spot is almost entirely white. 
II. A slightly smaller specimen, unfigured. (1) very 
he 
pale buff, (3) still paler. The latter not uniformly 
tinted. At a little distance both spots appear to 
be white. 
The specimen represented on Plate XXXI, Fig. 2. 
(1) distinct buff, (8) and (5) very pale buff, the 
tint of (3) being even fainter than in the specimen 
last mentioned. At a little distance all spots 
except (1) appear to be white. 
IV. The dwarfed specimen represented in Fig. 5. The 
condition is similar to that described in No. III, 
except that spot (8) is of a very slightly deeper 
shade. Nevertheless, at a little distance all the 
spots appear to be white except (1). 
V. The specimen represented in Fig. 4. (1) buff of a 
slightly deeper shade than in specimen No. III. 
(3) very distinct buff. (5) outer half of the area 
distinct buff. The lens shows traces of the same 
tint on (2) and (4), but to the eye these two spots 
and the costal (or inner) half of (5) appear to be 
white. 
VI. The much-dwarfed specimen represented in Fig. 6. 
All spots except (4) butf, with an appearance of 
additional depth of tint caused by the over- 
spreading of dark scales—an encroachment of the 
ground-colour of the wing. (4) appears to be 
white or very pale buff at a little distance, and is 
much less overspread than the others. The depth 
of the shade of buff is most marked in (1), then in 
(2), (5), and (3) in this order. 
The dwarfed condition of specimens 4 and 6 is worthy
