jections; margin of pygidium irregularly crenulate; dorsal 

 and ventral surface with few irregularly distributed oracera- 

 tubae; anus large, circular, located near middle of pygidium; 

 pygidium of second nymphal female resembling species of 

 Parlatoria or Gymnaspis; scale of male and first nymphal fe- 

 male, when present, with number of long curling glassy brittle 



processes of wax. — Australia on Callistemon pulchra Green. 



aa. Pygidium of adult female with symmetrically arranged projections, 

 apparently lobes and not pseudolobes. 

 b. Pygidium of adult female with more than two pairs of lobes. 



c. Pygidium of adult female with four pairs of lobes, pygidium 

 transverse with caudal margin subtruncate; median pair of 

 lobes narrow, subquadrangular, mesal and lateral notches; 

 second pair of lobes projecting farther caudad than median 

 lobes, similar in shape, mesal and lateral notches; third and 

 fourth pairs of lobes successively shorter than each dther and 

 second pair of lobes, mesal and laternal notches; plates slender, 

 hardly longer than lobes, arranged 2, 3, 5, 5, 6, those of lateres 

 adjacent to fourth pair of lobes; cephalic end of body with 

 deep mesal cleft. — Ceylon on Loranthus loranthi Green. 



CO. Pygidium of adult female with three pairs of lobes and pygi- 

 dium semicircular, caudal margin uniformly convex, never 

 subtruncate; median pair of lobes distant, bluntly pointed, 

 subtriangular, entire; second pair of lobes similar in shape 

 to median pair, more than twice as far from median as dis- 

 tance between median pair of lobes, entire; third pair of 

 lobes minute, similar to second pair; plates of second and 

 third incisurae twice or more as long as lobes, arranged 2, 3, 

 3, 2, those of lateres adjacent to third pair of lobes; each lat- 

 eris with two indentations; cephalic end of body entire, not 



cleft. — Ceylon on Loranthus. ohscura Green. 



bb. Pygidium of adult female with two pairs of lobes. 



c. Pygidium of adult female without pectinae or plates; median 

 pair of lobes contiguous at proximal end, bluntly pointed, tri- 

 angular, lateral margin with two notches; second pa^ir of lobes 

 small, triangular, entire; each lateris with three equidistant 

 setae and two broad emarginations or indentations; pygidium 

 of second nymphal female with three pairs of lobes, median 

 pair not contiguous, mesal margins straight, distal and lateral 

 margins continuously rounded, notched; second pair of lobes 

 broader, deeper lateral notch; third pair of lobes bluntly 

 pointed, triangular, lateral margin serrate; pectinae narrow 

 distapectinae, arranged 2, 2, 2, 2, those of each lateris distant 

 from third lobe width of lobe; each lateris coarsely crenulate. 

 — Europe on Laurel. Imiri Bouche. 



cc. Pygidium of adult female with median pair of lobes separated 

 by pair of long, slender, plate-like pseudolobes, twice as Icng 

 as lobes; median and second pairs of lobes long, slender, sides 

 parallel, two or three times as long as wide; second incisura 

 with long, broad, dagger-like plate and one or two cephalad 

 of each second lobe; plate-like projections variable in size
