ately, and the lateral margins of the orifice are somewhat incurved pos- 

 teriorly beyond the operculum. Eyes maroon. Abdominal segments 

 distinct. Antenna? and legs present. The artist has drawn the vasi- 

 form orifice as seen by him through the transparent body. 



Larva 2nd stage. Size '45 mm. X '32 mm. 



Shape elliptical ; colour yellow. Two yellow pigment patches in 

 centre of abdominal region. Two curved hairs caudad on margin. Va- 

 siform orifice as in the pupa-case, but the orifice is situated quite close 

 to the margin. Abdominal segments distinct. Eyes maroon. A mar- 

 ginal fringe of stout, cylindrical; waxy filaments which are placed quite 

 close together. 



Larva 3rd stage. Size '7 mm. x "5 mm. 



Shape elliptical, margin at thorax angled slightly outwards. Dorsum 

 almost flat. Colour yellow. Two seta? caudad, and two seta? placed 

 caudolaterally on margin. A marginal fringe of stout, cylindrical wax 

 filaments. Eyes maroon. Abdominal segments distinct. Dorsum granu- 

 lar near margin. Margin broad, faintly demarcated mesad, and deeply 

 striated radially. There is a distinct yellow band extending from the 

 posterior extremity of the vasiform orifice caudad to margin. There 

 are faint indications of the two radial thoracic bauds so conspicuous in 

 the pupa. They end, as also does the band extending caudad to margin, 

 in five separate brown horizontal pores which secrete a small quantity of 

 brown wax. Dorsum covered with a large number of extremely minute 

 circular pores. 



Larva 4th stage. Size L25 mm. X 1 mm. 



Similar to pupa-case except in size, it is also flatter. 



Puparium. Size. LS6 mm. x 1'52 mm. 



Shape oval, anteriorly the thoracic margins angled outwards, giving 

 the anterior end a somewhat square appearance. Colour bright yellow. 

 Dorsum atfirst somewhatflat, later turning fairly convex. Three ridges on 

 dorsum, two radiating from thorax to cephalo-thoracic margins, and one 

 from the posterior end of the vasiform orifice caudad to margin. These 

 ridges are dark yellow, blotched with grey. They end marginally in five 

 stout distinct brown pores which produce a small quantity of brown 

 fluffy wax. Margin broad, demarcated mesad by a fairly broad distinct 

 white band the inner edge of which is dark brown. Margin with strong- 

 ly marked radial striations, the dorsum also marked around the central 

 area, but the markings are more granular than striated. A small quan- 

 tity of short stout waxy filaments produced from marginal pores spaced 

 some distance apart. There are also a series of submarginal pores which 

 produce finer and longer wax filaments. They are also spaced some 

 distance apart. There are two small slender setae on cephalic, and two
