Copulatory Apparatus (Figs. 5 and 6). Almost normal male, 

 except the hind margin of the yth abdominal sternite which bears 

 slightly stronger indentations than those in the normal male. 

 The female structures absent.

 ventral view; abbreviations the same as in Fig. 5. Zeiss, obj. AA, oc. I. 



Thus, in this case, the pigmental and structural sexual differ- 

 entiations of the wings and structural sexual features of the 

 antennae, strongly divided by the plane of bilateral symmetry, do 

 not correspond with the differentiation of the genital armature.
