Egg.—Size about 0.2 by 0.092 mm.; yellowish, considerably convex 
on one side; unmarked, stalk short, attached to egg at one side of 
basal end. 
Larva.—Size about 0.55 by 0.87 mm.; pale yellowish white; subel- 
liptical, becoming narrower caudad; abdominal segments but moder- 
ately distinct across the middle. No distinct marginal rim. Margin 
crenulated, the lobes somewhat truncate, and separated by linelike 
incisions. | 
There is a pair of sete at vasiform orifice, and a pair just within 
caudal margin of case. There is also a pair on caudo-lateral margin of 
case and on the cephalic margin. There is no dorsal exudation of 
wax. Vasiform orifice practically as in pupa case. Legs and antenne 
obsolete. Eye spots quite small and reddish. 
Pupa case.—Size about 0.92 by 0.63 mm.; shape subelliptical as a 
rule, somewhat pointed cephalad, and broadly rounded caudad; widest 
about the middle, or just caudad of middle. Under hand lens case 
is shiny black in color; dark brown by transmitted light under micro- 
scope. There is ordinarily no lateral fringe, but there is a beautiful 
ellipse of white waxy bands or ribbons from the submarginal area of 
the dorsum. These project from the case more usually at an angle of 
about 45°, and are but little curved; they are truncate distally, 
of varying width, and rarely as long as the case is wide. There are 
along the longitudinal dorsal region three distinct white waxy secre- 
tions; at vasiform orifice is a concave shell-like plume or ribbon, one 
on each side of orifice, forming at base a much flattened tube, the
