Grapefruit Leaf, Showing Yellow Aschersonia Infecting the Cloudy-Winged 
White Fly. 
[The parasitic fungous pustules are overgrown in spots by sooty mold and sooty mold is also shown 
developing around the edges of infected pupae. More, rather than less, sooty mold usually accom- 
panies as extensive an infestation by the yellow fungus as that shown on this leaf. (Original.)]
