pair apical, 1 pair median, 1 pair basal ; spiracle with 2 trilocular pores or with 1 

 trilocular and 1 quinquelocular pore ; leg setae, coxa 3, femur 0, tarsus 1 each 

 on inner and outer margins; tibia one-third as long as tarsus; 5 pairs of sub- 

 marginal 8-shaped pores of which 1 pair is between the antennae ; 10 pairs of 

 minute submarginal setae, on abdomen, thorax, and head ; 2 pairs of setae near 

 antennae. 



Apex of abdomen : Setae, apical about 36 p long, interapical 9 fi long, one 1 p 

 long mesad of interapical, outer ventral 0.5 /* long; anal opening an elongate 

 incision in ventral surface close to margin; anal tube short bulbous, heavily 

 sclerotized ; anal ring a constriction at inner end of tube. 



Data. — Redescribed from three unmounted specimens, one mounted 

 female, and three mounted larvae on Livistona humitis, Stapleton, 

 Northern Territory, Australia, from E. E. Green, received in 1933, 

 type. 



Green stated (43, p. 64), "After examination of many preparations, 

 I have been unable to locate the position of the anal orifice." In the 

 well stained specimen examined by the writer the anal orifice is clearly 

 defined. 



This species is most closely related to unieum. 



ASTEROLECANIUM HORISHAE, new species 



(Fig. 31, A-G; pi. 9, Y) 



Discussed under the name Asterolecanium japonicum Cockerell in 

 1934 (96, p. 4) by Takahashi, who indicated, however, that he was not 

 sure of his identification. 



Habit. — Living on both surfaces of leaves. 



Test of female. — Slightly longer than wide, measuring 0.8-1 mm. long and 0.75 

 wide, posterior end produced ; flat or slightly convex dorsally, with a faint 

 longitudinal median carina and transverse striations in median area, flat ven- 

 trally ; pale greenish yellow, transparent, punctate ; marginal filaments pale 

 golden yellow; dorsal filaments absent or arranged in 2-7 groups, pale golden, 

 slightly shorter than marginal filaments ; larval exit elliptical, in dorsal surface 

 at margin. 



Adult female. — Slightly longer than wide, measuring 0.8-1 mm. long and 0.7 

 wide, or circular, 0.75-0.9 mm. in diameter. 



Margin : 8-shaped pores in a single row terminating two to three times a 

 pore's length from bases of apical setae, each pore with a short, sclerotized, 

 tongue-shaped projection on dorsal edge, posterior pores 7 /a long and 4 wide, the 

 others 8 n long and 5 wide, distance between pores ranging from width to length 

 of a pore; usually 3-39 quinquelocular pores near point where each spiracular 

 pore band meets margin. 



Dorsal surface : 8-shaped pores sometimes absent but often in 7-10 groups of 

 2-11 pores each, the groups following the margin but well removed from it, and 

 apparently not at uniform distances from each other, not observed near posterior 

 end, the individual pores usually around 5-6 /* long and 4-5 wide, but the posterior 

 pores sometimes 3-4 /* long and 2 wide ; minute 8-shaped pores numerous ; disk 

 pores fairly numerous ; tubular ducts 20 ix long. 



Ventral surface: Antenna circular, flat, usually with 2 setae slightly longer 

 than diameter of antenna ; beak with 2 pairs of setae ; spiracular bar slightly 

 expanded at inner end; 3-15 (usually 6-8) quinquelocular. pores extending from 

 spiracle to body margin in a single row; multilocular pores, totaling 29-36 and 

 having 10 loculi, arranged in 4 complete rows of 6-10 each ; 1 or 2 dark-rimmed 

 8-shaped pores each side of beak and 3 or 4 on anterior end ; submarginal 8-shaped 

 pores in a single row terminating near the posterior pair of marginal 8-shaped 

 pores and usually nearly as numerous as those pores ; 7 pairs of submarginal 

 setae posterior to posterior spiracles, the posterior pair fairly near the pos- 

 terior pair of marginal 8-shaped pores ; 2 pairs of setae in the posterior row, 1 

 pair in each of the other rows of multilocular pores. 



Apex of abdomen : Lobes barely indicated ; setae, apical 48 /m long, interapical 

 3.5 fi long, outer ventral 2 ^ long ; anal opening ventral, close to margin, circular, 

 its margin membranous, usually without, but occasionally with, 1 seta 1 fi long.
