Nymphs — The winged viviparous females ns well as the stem mothers or 

 a|)terous viviparous females were giving rise to great numbers of the young of 

 the winged females, there being none of the apterous young produced in this way 

 within the galls. These nymphs vary from almost transparent white or yellowish 

 to a dusky green color with amber or pinkish thoraxes. Legs dull yellowish or 

 whitish with dusky articulations. Rostrum light with dark tip and extending just 

 beyond posterior base of the first eoxie and not ijuite to the second coxir. The 

 bodies are early covered with a fine white powder which gives theni a ifrayish or 

 whitish ajipearance.
