Fii<. 7. Gynandromorphous Ayriades coridon (Herts, race). Taken by the Rev. 



G. H. Raynor. External genitalia purely ? . Ovaries present. 

 Fig. 8. Gynandromorphous A(jiiudes coridon (Herts, race). Blue ? with male scent 



scales (androconia) on both forewings. Unique example in Mr Pickett's possession. 

 Fig. 9. Gynandromorphous Ayriades coridon (Herts, race). Brown J with male blue 



scales, hair scales and androconia on both forewings. ' External genitalia purely 



? . Ovaries present. 

 Figs. 10 and 11. Gynandromorphous Agriades coridon (Herts, race). 



Fig. 10. Upper specimen has male bine .scales, hair scales and androconia near central 



spot on right forewing, left side very small, no androconia, no blue scales. Lower 



one blue scale on left forewing, none on right. For underside see Fig. 12. 

 Fig. 11. Heterochroic. Right ab. tiurantia Tutt ; Left type. 

 Fig. 12. Underside of same insect. Note large right side ab. parisiensis Gerh., with 



black basal area, small left side with typical spotting. Great asymmetry of marginal 



orange lunules and of all spots. Pickett's specimen. 

 Figs. 12 a and 12 b. Example of gynandromorph with very asymmetrical underside. 



Ayriades coridon of the Herts, race. Upper and underside. The latter shows right 



side small and typical ; left side large and ab. parisiensis Gerh. The right upper side 



shows blue scales, androconia and male hair scales. 

 Fig. 13. Gynandromorphous Agriades coridon (Herts, race). Scanty blue (male) 



scaling on both wings, blunting of right apex. 

 Fig. 14 a. Ayriades coridon, a.h. semisyngrapha; Gynandromorphous. Left side smaller. 



Hair scales and androconia present. 



PLATE XXIII. 



Figs. 1'4, 15, 16. Fairly average examples of the race of Herts, coridon which show 

 hereditary gynandromorphism (secondary somatic hermaphrodites). Side with male 

 blue scales, male hair scales and androconia, small orange lunules, is smaller than 

 purely ? side. 



PLATE XXIV. 



Fig. 17. Part of wing of gynandromorphous Agriades coridon of Herts, race, which on 



dissection proved to be a secondary somatic hermaphrodite, showing androconia, 



male hair scales, male blue scales both serrated and smooth, and ordinary brown 

 ' serrated female scales. 

 Figs. 18 and 19. Upper gynandromorphous Polyommatus icarus predominantly ? ab. 



coerulea with streaks of male colour in apex of right forewing and in both hindwings, 



note that these cut tlirouyh the lunules. 

 Lower gynandromorphous P. icams (symmetrical), predominantly male, but showing 



fine mosaic of female scales intimately mixed with male scales and orange lunules, 



also a female character. 

 Both are unique forms of this species.
