In Lepidopteni Speyer calculates that about one in 30,000 is a 

 gynandroniorph, and though there is little doubt that they occur more 

 frequently in this species, the proportion is probably not higher than 

 one in 5000 to 10,000. 



I have dissected eight of these gynandromorphous A. popidi, three 

 of which are figured (PI. XXI, fig. 5) and diagrams of their genital 

 ajjparatus are also given (Diagrams a — i). 



The following are descriptions of these individuals. 



(1 ) (Diagram a.) PI. XXI, fig. 5 a. Left side </• 



Right side predominantly % (both wings partially crippled). 



Colour : the same shade of grey on both sides. 



R. antenna intennediate. 



R. palpus %. 



R. half of thorax smaller and with .shorter hair.
