is placed beyond the end ol 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 iu 

 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 



pale buff, (3) still paler. The latter not uniformly 

 tinted. At a little distance both spots appear to 

 be white. 



III. The specimen represented on Plate XXXI, Fig. S. 

 (1) distinct buff, (3) and (5) very pale buft', 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. Ill, 

 except that spot (3) 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 reprefonted in Fig. 6 

 All spots except (4) buff, 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
