Puparium of the female (PL I, figs. 7, 1 4) circular, 

 moderately convex. Dark madder brown, purplish 

 black, or reddish brown, paler towards the margin, 

 where it is sometimes greyish or white. Exuvise 

 central; that of the larva dark orange brown or bright 

 golden yellow, presenting a metallic appearance or 

 lustre; secretionary covering circular and nipple- 

 shaped; central portion white, but it is almost 

 invariably wanting in the old examples ; second exuvige 

 completely hidden beneath the secretionary covering, 

 which forms a more or less flat, dark, purplish-brown

 there is an extremely thin secretion on the tissues of 

 the food-plant. Young scales are circular (PL I, fig. 8) 

 and reddish brown; they are frequently superposed 

 upon the scale of the female (fig. 7).
