aa. Thorax with mesopsiracerores wanting; pygidium without lobes, 

 plates, pectinae, or pseudolobes, margin slightly undulate and finely 

 serrate; dorsal and ventral row of marginal setae; pygidium with 

 sides converging rapidly caudad, subtriangular, not broad, broadly 

 rounded; anus located cephalad of vulva in line with mesogena-

SPECIES OF ISCHNAFIORINIA 



Scale of adult female elongate, twenty-five or more times as long as wide, 

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

 parent, color white, appears yellow 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 

 with few "spiny hairs" between and near median lobes; genacerores 



arranged in two groups of three cerores each. China on Bambusa 



bambusae Mask. 



SPECIES OF PARAFIORINIA 



a. Insect living free, not producing galls. 



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 



Mask. Australia on Acacia. rubra Mask. 



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. nephelii Mask. 



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

 pygidium of adult female with median pair of lobes projecting, ex- 

 ceeding in length adjacent setae; other lobes wanting; dorsal and 



ventral oraceratubae wanting. Algeria on Nephelium

SPECIE'S OF ADISCOFIORINIA 



a. Pygidium with irregular arched group of "circumgenital glands" on 

 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
