 freshly emerged iinaginal Mdngs. (x 6). Lettering as on p. 535. 



the continuation of Cv^ beyond the bend formed by M 5 . It 

 should also be noted that, in the forewing, Cu 2 becomes aborted 

 through the breaking of its connection with trachea Cu. In the 

 wing from which Text-fig. 92 was drawn, a little piece of this 

 trachea remained near the base, and a longer piece distally. 

 The chitinisation of the vein Cu 2 in both wings, and of the 

 anal veins in the hindwing, is very weak. 



In Text-fig. 93, the actual venation is omitted, the figure being 

 intended to show the courses of the tracheae. The veins them- 

 selves are stout, especially Sc in forewing. They enclose all 

 the main tracheae and their branches, and also complete the basal 

 cell distally, and the anal loop in the forewing.
