Ovisac of adult female (PI. LXI, figs. 1-4) glassy 

 and semi-transparent; elongate, highly convex, and 

 slightly narrowed behind ; transverse anal opening at 

 the extreme margin ; ventral surface normally more or 

 less flat, but varying according to its position on the 

 food-plant sometimes it is quite convex, but when 

 fixed to a slender branch (PI. LXI, fig. 5) it is deeply 

 concave. Colour varying according to the age of the 

 imprisoned insect, or of its other contents. In young 

 examples (PL LXI, fig. 5) it is of a uniform pale 

 lemon-yellow ; at the period of parturition (PL LXI, 

 figs. 3, 3 a) the anterior half is usually of a more or less 

 ochreous yellow, with dull crimson blotches, the pos- 

 terior portion being paler; after the escape of the 

 larvae the anterior third is usually dark brown, with 

 the remaining portion dusky ochreous (PL LXI, fig. 4).
