aa. Pygidium with four pairs of paraphyses; median pair of lobes large, 

 prominent, strongly convergent, prominent lateral notch, lateral 

 margin oblique, distal end rounded; median incisura narrow, with- 

 out plates; indentation marking second incisura with two short 

 plates and two subequal clavate paraphyses, as long as or longer than 

 median lobe; minute projection cephalad of second incisura, prob- 

 ably representing lobe, cephalad of this a plate; two cephalic para- 

 physes of each side adjacent, clavate, as long as caudal paraphyses; 

 single plate cephalad of cephalic paraphyses; anus distant from 

 caudal margin; dorsal oraceratubae few and inconspicuous. — Aus- 

 tralia on Acacia. subfervens Green. 



SPECIES OF NEOLEONARDIA 



Pygidium with median pair of lobes fused into a single lobe, circular, 

 entire; each lateris with four stout truncate plates, in two groups of 

 two each, separated by indentation, another indentation cephalad of 

 cephalic group of plates, each indentation with two long setae, plates 

 nearly as long as lobes; paraphyses four in number, cephalic portion 

 swollen, club-shaped, mesal paraphyses longer than lateral, shortest 

 three or more times as long as median lobe; caudal portion of pygi- 

 dium constricted and margins emarginate. — Australia on Eucalyptus 



extensa Mask. 



SPECIES OF GREENOIDEA

 mesal notches; second, third, and fourth pairs of lobes similar, round- 

 ed, smaller than median, lateral notch; paraphyses two or three times 

 as long as wide, attached mesal margin of second, third, and fourth 

 pairs of lobes; proximal ends of median pair of lobes prolonged; calles 

 present; plates or pectinae wanting; anus near middle of pygidium. — 

 Ceylon on Phyllanthus. phylJanthi Green. 



SPECIES OF MASKET.LIA

 ond and third pairs of lobes short and broad, notched at distal end, dis- 

 tance between them three times distance between median and second 

 lobe; each lateris with projections at middle; setae on ventral side of 

 proximal end of lobes and lobe-like projections and on dorsal side of 

 second and third pairs of lobes and lobe-like projections; anus slight- 

 ly nearer caudal than cephalic end of pygidium; insects forming galls 

 on twigs. — West Australia on Eucalyptus globosa Fuller.
