Puparium of the female (PL III, figs. 9, 13), obconical 

 or thimble-shaped, the height almost equalling the 

 greatest diameter, surface roughly and irregularly 

 laminate, but shining, usually tilted to one side. Colour 

 black, blackish brown, piceous, or sometimes smoky 

 grey; laminae grey or white; denuded examples more 

 polished than those with the laminas perfect. Exuviae, 

 at the highest part of the puparium, dull red, secre- 

 tionary coverings black, the extent of each indicated by 

 white concentric rings, and there is usually a central 

 boss or nipple. Ventral scale (PL III, fig 10) about 

 half the greatest diameter of the whole ventral surface ; 

 unicolourous pale brown. The remainder of the ventral 

 surface consists of a broad, thick flange, which is un- 

 doubtedly a continuation of the upper part of the 

 puparium. A very thin secretion generally remains 

 attached to the plant (PL III, fig. 11) which is ochreous, 

 with two small dark concentric rings, followed by 

 others of pale blue and dark brown. Tissues of the 

 leaf immediately surrounding these dull orange.
