Explanation of Plate XXIV. 

 Figs. 



14 — 19. These specimens have an additional fore-wing spot (4a) 

 beyond (4) and over the end of the cell. The normal spots 

 (l)-(4) are fully developed in all except the example repre- 

 sented in Fig. 14. Fig. 18 shows a rather marked transition 

 towards the hippocoon pattern, in the pale linear patch on the 

 inner margin of the fore-wing and the extension downwards 

 and outwards of the chief spot (1) in the same wing. 



20, 21, These females have another additional fore-wing spot (2rt), 

 between (2) and (3). 



22. The single hippocoon female form in this family. Spot (5) 

 within the fore-wing cell is seen to be divided, as in the parent. 

 A similar division of (5) is seen in many of the cenea offspring 

 as described on pp. 440, 441.
