Gi/nandromorphs partly of male type colour, and partly of 

 aberrational rolnur limifed to the female sex. 



It is well kiiiiwn that there is in some regions, iiotaLly in the New 

 Forest, a dark form, ab. videsiiia, of Dryus papliia, limited to the female 

 sex. In several species of Coitus normally orange in both sexes there is 

 a white or lemon-coloured aberration also limited to the female. An 

 instance of this is the ab. helice of the common clouded yellow, Golias 

 edusa. 



Of Di'yas paphia many gynandromorphs have been taken. Most of 

 these are halved externally, but some show one or more patches of 

 female colour on the male side or vice versa. In others there is a coarse 

 mosaic arrangement of male and female pattern and colour. In a 

 considerable number of these gynandnjuiorphs all the female parts of 

 the wing are of the dark colour of the ab. valesiiia. 



The following will serve as examples of this. In Schultz's lists no 

 less than 20 halved gj-nandromorphs of D. paphia are given, in which 

 one half was male type and the other female ab. valesina. In addition 

 less symmetrical examples are recorded. 



(«) Right forewing male, right hindwing male Hecked with dark 

 colour of ab. valesina. Left forewing mixed patches of fuhous male 

 colour and female ab. valesina. 



(b) Right side male paphia, left side male paphia, with a broad 

 streak of valesina colouring along the costa of the forewing and a small 

 streak in the hindwing. {Iris, 1913, XXVI, Coloured Plate, Taf vii. 

 Fig. 4.) 



(c) Male paphia on right side with patch of valesina colour on 

 forewing; left side wholly valesina. 



Mr Newman tells me that from a valesina ^ he generally obtains 

 60 7o </"</. 40 7. ? ? (20 7o type ? and 20 7, valesina ? ). 



Professor Puunett also obtained about .50°/^ j/'(/', and 25% of each 

 of the % forms.

(b) Right side male : left female ab. helice. 

 Golias erate.
