Dorsal surface : 8-shaped pores in a submedian row of 7 on each half of body, 

 anterior pores slightly larger than posterior ones, all a little smaller than marginal 

 pores ; disk pores close to submedian and to marginal 8-shaped pores. 



Ventral surface : Antennal setae, I, 1 ; IV, 1 ; V, 1 ; VI, 2 long, 2 stout, 3 fairly 

 stout, 2 slender; distance between antennal bases equal to one-fifth length of 

 antenna ; beak setae, 2 pairs apical, 1 pair basal ; anterior spiracle with 1 trilocular 

 and 1 quinquelocular pore, posterior spiracle with none ; leg setae, coxa 4, femur 

 1 on inner margin near base and 1 on outer margin near center, tarsus 1 each on 

 inner and outer margins ; tibia about one-half as long as tarsus ; 10 pairs of sub- 

 marginal 8-shaped pores ; 10 pairs of submarginal minute setae, on abdomen and 

 thorax, 1 pair of submarginal larger setae at anterior end ; 2 pairs of setae between 

 antennae and mouth parts. 



Apex of abdomen : Notch present ; lobes sometimes indicated ; setae, apical 65 fj. 

 long, interapical 7.2 ll long, one 2.5 m long usually present entad of interapical on 1 

 side of body only, inner ventral 3.6 /x long, outer ventral 5.4 /x long ; anal opening 

 in margin ; anal tube short ; anal ring with 4 setae about 5.4 n long. 



Test of male. — Elliptical. 1 mm. long, 0.75 wide ; slightly convex dorsally, with 

 a longitudinal median carina ; flat ventrally ; yellow, transparent, thin ; marginal 

 filaments whitish. 



Adult male. — 0.95 mm. long. 



Head : Antenna broken ; basal bars transverse ; 9 setae anterior to ventral 

 eyespots. 



Thorax : Bar between wing bases curved on anterior margin, two-fifths as 

 long as wide, with a median longitudinal fold ; tibia as long as tarsus. 



Abdomen: Five segments each with a seta dorsally on lateral margin, 3 

 segments each with a seta in ventral lateral area ; each lobe area with 1 long 

 and 2 short setae ; penis sheath very long, with 3 pairs of setae dorsally near 

 base and 8 or 9 setae on each side of ventral opening. 



Male nymph. — Distinguishing characters similar to those of adult male. 



Data. — Described from specimens (four females, three larvae, one 

 adult male, and one male nymph, mounted) on Leptospermum sp., 

 Sandringham, Victoria, Australia, from Ch. French, received in June 

 1905, holotype and paratypes. 



Allied to vitreum. 







Asterolecanium viennae, new species 



(Fig. 80, A-I: pi. 5, D) 



Habit. — Living in pits in the bark. 



Test of female. — Roughly circular, approximately 1 mm. in diameter, posterior 

 end usually slightly produced and turned forward; more or less convex dorsally, 

 with faint transverse striations. and sometimes with a faint longitudinal median 

 carina: nearly flat, or convex ventrally: bright greenish yellow, semitransparent, 

 shiny, punctate : marginal filaments whitish ; larval exit at or close to end of 

 produced area. 



Adult female. — Nearly circular, posterior end slightly produced ; approximately 

 0.95 mm. in diameter. 



Margin : 8-shaped pores mostly in an irregularly double and single row ter- 

 minating around one-half length of apical seta from setal bases, 8-10 ,u long and 

 5-8 wide, usually a pore's length apart ; quinquelocular pores in a single row 

 of 4-17 (usually 10-12) where each spiracular pore band meets margin. 



Dorsal surface : Minute 8-shaped and disk pores numerous ; tubular ducts 28 fi 

 long. 



Ventral surface : Antenna short, with 2 setae as long as diameter of antenna : 

 beak apparently with 2 pairs of setae : spiracle with bar slightly expanded at 

 inner end ; 21-45 quinquelocular pores extending from spiracle to body margin 

 in a row which is double or triple at opening but 8-12 pores wide at margin ; 

 enlarged trilocular or quinquelocular pores replacing multilocular, in 2 rows of 

 1-3 each ; dark-rimmed 8-shaped pores not observed ; submarginal 8-shaped pores 

 usually in an irregularly double row terminating near anterior row of multi- 

 locular pores, at least as numerous as corresponding marginal 8-shaped pores : 

 submarginal setae in a complete row terminating fairly near penultimate pair of 

 marginal 8-shaped pores : 1 or 2 pairs of setae in posterior row and 1 pair in 

 anterior row of enlarged quinquelocular pores, and 3 pairs anterior to those, the 

 latter uniformly spaced.
