Egg. — Length, .16 mm.; width, .oS mm. j elliptical, curved, light 

 brownish in colour, marked with minute polygonal areas ; pedicel short, 

 about one-tenth length of egg. 



Larva. — Length, .43 mm.; width, .3 mm., varying somewhat ; shape, 

 elliptical ; colour, whitish or yellowish white. Margin all around dentate, 

 due to the usually short but acute incisions between the closely-set wax 

 tubes. A very fragmentary marginal fringe frequently present ; no sub- 

 marginal rim as in pupa-case. Wax tubes plainly extending mesad four 

 to five times their breadth, then gradually disappearing. Abdominal 

 segments moderately distinct. Eye spots small, reddish. Dorsal tuber- 

 cles and seta^ usually present as on pupa-case, but those of thorax 

 sometimes wanting. Vasiform orifice, operculum and lingula essentially 

 as in pupa-case. Exuvia; from preceding moults frequently remain 

 attached to larva. 



Pupa-case. — Length, .7 mm ; width, .55 mm.; shape elliptical, 

 varying somewhat in size and shape. Under hand-lens, shiny black in 

 Colour; dark brown by transmitted light under microscope. Conspicuous 

 white cottony fringe all around ; wax rods, closely matted together at 

 base, distinctly becoming more separated, giving the outer margin of 

 fringe a ragged appearance. There is a distinct marginal rim of wax 

 tubes, which extend mesad with varying distinctness to the inner margin 

 of rim. Outer margin crenulated, due to the shallow and usually rounded 

 indentures between wax tubes ; rim marked with minute dots. 



Abdominal segments moderately distinct ; abdomen slightly raised 

 along dorsi-meson, particularly from about the third segment caudad, 

 including vasiform orifice. . Third thoracic segment moderately distinct, 

 straight. A median suture extends cephalad to marginal rim from first 

 abdominal segment. On the dorsum of both mesothorax and metathorax
