Puparium of adult female (figs. 1 3) elongate 

 ovate, or pyriform, flat convex. Orange-yellow faintly 

 tinged with green, the laminations usually much darker. 

 Exuvias marginal ; those of the larva ovate, and fre- 

 quently projecting, are yellow with a posterior blotch 

 of dark bluish-green ; second exuviae, almost circular, 

 occupy more than one third of the puparium, and of 

 the same colour as those of the larva; secretionary 

 covering usually forming a complete marginal ring. 



In cabinet specimens the margin of the puparium 

 becomes greyish; the dark blue-green patch on the 

 first and second exuviae fades ; but the orange-yellow 

 of the puparium remains bright for an indefinite period. 

 The ventral surface is trough-shaped, and when viewed 

 by transmitted light (fig. 4) the broad flat lateral 

 margins are seen to be ramified by branched vessels 

 resembling capillaries, and are very strongly indicated 

 in fresh examples. 



Long. 1*50 2 mm. 



Adult female (fig. 5) usually of a faint, translucent, 

 purple or mauve, with crimson blotches on the cephalic 

 and thoracic segments. Papillae on the dermis of 

 cephalic area much more chitinised and conical, but 

 fewer than in P. pergandii ; and the hairs are almost 

 entirely wanting. The groups of eircumgenital glands 

 are remarkable for the constancy of their numbers, as
