This parental influence upon the tint of offspring belonging 

 to a different form is extremely interesting, especially when, 

 as in most cases, no other visible effect is produced. 



In describing the spots of the fore-wing the terminology 

 suggested in Trans. Ent. Soc, 1908, p. 433, is followed. 

 The submarginal spots (a) (ft) and (y) are normal in 15 

 specimens, (a) is so minute as to be nearly invisible in 

 23 and 41 : it is wanting and (/3) minute in 40 and 47 : 

 both are wanting and (y) minute in 1 and 54. The missing 

 spots are present on the under surface of all these specimens. 

 The apical spot (8) is wanting from both surfaces of 1, 45, 



and 53. 



All the spots of the fore-wing upper surface are white 

 in 6, 15, 23, and 47, and in 17, 22, 27, and 42 except for a 

 faint yellowish tinge of the inner marginal border of the 

 principal spot (1). In speaking of " spots" I do not include 

 the streak along the inner margin (in 15, 27, 42, 51, 55, 

 and minute traces in a few others), or the extension down- 

 wards and outwards from spot (1) into interspace 15 (in 

 23, 27, 41, the right side of 15, and slight indications in 

 several others). The above-mentioned markings where pre- 

 sent in this family are invariably ochreous. (1) is darkest

ochreous in 1 and 9 in which the other spots are pale 

 yellowish, the tint being most distinct in spot (3). In the 

 12 remaining specimens (1) is pale yellowish and the other 

 spots white except (3) and more rarely (5) which in some 

 specimens are very faintly tinged with yellow. 



Spot (2a) between (2) and (3) is present and of large size 

 in 15, 23, and 42, minute in 6, 17, 27, 25 and 45, minute 

 and only on the left side of 41. It is present on the under 

 surface of all these and a few others. A new spot (3a) not 

 hitherto described is placed in the angle between veins 7 

 and 8, where they diverge from each other, in 9 and 45. A 

 minute spot (4a) is present in a single specimen 52. 



Spot (5) within the cell is divided into two in the usual 

 manner in about half the specimens of cenea : it is small in 

 a few and minute in 54. 



The 22 cenea offspring are thus a very interesting set,
