which produce a very fragmentary fringe. These pores are situated on 

 a slightly higher plane than the margin. Margin incurved at sides of 

 cephalothorax and at caudal margin. There are eight large and dis- 

 tinct wax tubes on each of these areas. Region around these inden- 

 tures tinged with brown, which, in the case of the caudal indenture, 

 reaches to the vasiform orifice. Eyes reddish. Two small setae on the 

 cephalic margin. Two small setae caudad just within the margin and 

 placed one on each side of the incurved area. They point upwards and 

 outwards. Vasiform orifice similar to that in the larva 2nd stage. In 

 some specimens the orifice is almost circular. In others the anterior 

 margin and the sides are flattened somewhat, giving the vasiform orifice 

 a conical appearance, the apex pointing caudad. The edges of the ori- 

 fice tinged with brown. The orifice appears to project slightly beyond 

 surface of the dorsum. The operculum similar in shape to that in the 

 larva 2nd stage but is smaller in proportion and does not extend so far 

 caudad. Lingula as in larva 2nd stage. There is but little difference 

 except in size between this stage and the pupa, except that the insect 

 is more transparent, has the median keel on cephalothorax less promi- 

 nent and the operculum is larger, being intermediate in size between 

 that of the pupa and the larva 2nd stage. 



Puparium. Size 1 mm. x *78 mm. 



Shape elliptical, narrower cephalad. Margin at thorax and caudal 

 extremity incurved. Colour yellow. Dorsum elevated. A dark brown 

 elevated median keel running from thorax to cephalic margin beyond 

 which it slightly projects. At thorax a dark brown bar crosses the me- 

 dian dorsal ridge at right angles. Slightly posterior to this is another 

 line which is angled caudolaterally and then back again cephalolaterally. 

 Thorax suffused with brown ; centre of abdomen suffused with lighter 

 brown. Segments of abdomen fairly distinct along medio-dorsal line. 

 Vasiform orifice oval : anterior margin slightly flattened. Rim round 

 vasiform orifice dark brown. The lower portion of the orifice covered 

 with fine short hairs. Operculum small, similar in outline to vasiform 

 orifice. The lower edge extends to about the centre of the orifice. Sur- 

 face covered with fine hairs. Lingula short, cylindrical, difficult to ob- 

 serve as it is shorter than the operculum and does not extend beyond 

 that organ. Incurved areas at thoracic and caudal margins tinged 

 with brown. At these places the marginal pores are eight in number, 

 larger than the other marginal pores and differ in producing fairly long 

 filaments of white wax. A distinct series of pores right around on 

 margin. They secrete a quantity of gelatinous looking wax. Each in- 

 dividual filament is distinct for a certain distance beyond the margin 

 then coalesces to form a gelatinous mass with the others. Dorsum cover-
