99 WHITE FLIES INJURIOUS TO CITRUS IN FLORIDA. 
scope the waxy coating appears tinged with red. The eggs remain 
pale for three days, when about 96 per cent turn black, the rest taking 
sometimes as long as seven or eight days to darken. Meanwhile the 
waxy coating has turned gray. Because of the dark color and much 
tougher chorion, the eyes of the embryo are not as easily seen as are 
those of the citrus white fly. The eggs are attached to the leaf by a 
pedicel arising from the proximal end similar to that of A. citri. 
A study of the contents of Tables VIII and XIX will prove that 
what has been said of the duration of the egg stage, variability under 
identical temperature conditions, and effect of temperature in gen- 
eral, regarding the citrus white fly, applies almost equally well to this 
species.
