 cated at about same distance from caudal margin. — Fiorinia 



acaciae bilobis Full. — Australia on Acacia acaciac Mask. 



dd. Pygidium with genacerores arranged 3-3(6-6)5-6; mesospira- 

 cerores 0-2; median pair of lobes adjacent, entire, bluntly 

 pointed, hardly projecting beyond general contour of caudal 

 margin; plates wanting; pygidium cephalad of each median 

 lobe with three latadentes, bearing large oraceratubae. out- 

 lets of large allaceratubae ; setae large and prominent; pygid- 

 ium of second nymphal female with median lobes large, 

 mesal margins straight, adjacent, prominent lateral notch; 

 second pair of lobes large, deeply incised, mesal lobelet much 

 larger than lateral; third pair of lobes deeply incised, lobe- 

 lets short and broad; each second and third incisura with 

 long triangular plate and prominent latadentis and plate on 

 each lateris near third lobe. — Crypthemichionaspis nigra 

 Lindgr. — South Australia on Acacia, Phyllodian. nigra Lindgr. 

 CO. Pygidium with five groups of genacerores, mesogenacerores 

 and pregenacerores confluent or almost so, forming solagena- 

 ceroris of 40 to 50 cerores, postgenacerores consisting of 15-20 

 cerores; median pair of lobes short, broad, broadly rounded, 

 distant, with minute tooth-like projection between them; each 

 lateris with lobe-like projections; plates apparently wanting; 

 anus located in line with cephalic portions of postgenaceroris. — 



New Zealand on Brachyglottis. minima Mask. 



bb. Pygidium with margin adjacent to median pair of lobes finely 

 serrate, not with tooth-like projections; median pair of lobes nar- 

 row, much longer than wide, oblique, distal end obliquely trun- 

 cated; — Leonardi figures them as triangular, serrate, and contigu- 

 ous at proximal end; — plates wanting; altaceratubae long and 

 slender, linaceratuba-like; each lateris with indentations; vulva 

 on line drawn between pregenacerores and postgenacerores, anus 

 little farther cephalad; articulations of antennae distant; gena- 

 cerores 3-5(13-18)13-18; mesospiracerores obsolete; margin of body 

 with blunt marginal tubercles. — Ceylon. simillis Green. 



aa. Pygidium with mesal part of caudal margin deeply incised, median 

 pair of lobes situated in incision, 

 b. Pygidium as broad as long, never twice as long as wide. 



c. Head with antennae articulated close together and with short 

 cuticular projection bearing number of small spine-like points 

 between them, 

 d. Pygidium with median pair of lobes strongly oblique, proxi- 

 mal ends fused, mesal margins finely serrate on distal por- 

 tion; plates wanting; altaceratubae long and slender, lina- 

 ceratubae-like; each lateris with tooth-like projections adja- 

 cent to median pair of lobes and undulate cephalad of them; 

 anus on line drawn between pregenacerores and postgena- 

 cerores, vulva slightly farther cephalad; genacerores 8-8(15- 

 29)14-19; mesospiracerores 3; margin of body with blunt 

 marginal tubercles. — Ceylon on Saprosma. -saprosmae Green.
