 excessively slender, sides straight and parallel, wax thin and trans- 

 parent, color white, appears j'ellow from puparium showing through; 

 body elongate, several times longer than broad; pygidium with two 

 median trifoliate lobes, sometimes apparently wanting, figured as 

 slender knobbed spatulate structures; pygidial margin finely serrate

b. Pygidium with median pair of lobes adjacent, short, broad, broad- 

 er than long, mesal angle prominent, lateral margin broadly 

 roundly oblique, minutely serrate; caudal end of pygidium not 

 hollowed out, lobe-like angular projection at lateral margin of each 

 lobe; each lateris serrate with about nine "spines" on each side; 

 brevaceratubae apparently present. — Fiorinia rubra propinqua

bb. Pygidium with median pair of lobes adjacent only at proximal 

 end, strongly oblique, placed in a deep pygidial incision, distal 

 ends bluntly pointed, mesal margin finely serrate; each lateris 

 distinctly dentate, with few short thick "spines." — China, Formosa, 



Queensland on Nephelium. ncphclii Mask. 



aa. Insects producing galls, arranged in series around margin of leaf;

 ventral aspect at cephalic end adjacent to preabdomen; margin semi- 

 circular, without projections or indentations, with few short setae 

 just within margin; anus central in position; pygidium of second 

 nymphal female with distinct quadrangular lobes, longer than wide, 

 deeply notched for at least one-half their length, with four angular 

 adjacent lobe-like projections cephalad of each median lobe. — Egypt
