pores extending to body margin, no submarginal 8-shaped pores observed, and 

 no setae in median abdominal area ; apex of abdomen as in adult but all setae 

 usually slightly shorter. 



Larva. — Ovoid. 



Margin : Without 8-shaped pores ; a minute seta on lateral margin of each 

 of the 3 segments anterior to the last ; 2 pairs of setae at anterior end. 



Dorsal surface : Without pores. 



Ventral surface: Antenna indistinctly segmented, only 5 segments plainly 

 indicated; antennal setae, I, 0; IV, 1; V, 2 long, 2 stout, 2 fairly stout, 2 

 slender ; distance between antennal bases about one-half length of antenna ; 

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

 1 trilocular and 1 quinquelocular pore, posterior spiracle with none; anterior 

 coxa with only 2 minute setae, the others with only 1, but all with 3 long 

 setae, femur with 1 seta on inner margin near base and 1 on inner margin near 

 center, tarsus with 1 each on inner and outer margins ; tibia one-third as long 

 as tarsus ; the single pair of submarginal 8-shaped pores situated between the 

 antennae; apparently 9 pairs of submarginal minute setae, on abdomen, thorax, 

 and head, 1 pair of submarginal larger setae at anterior end ; 3 pairs of setae 

 between antennae and mouth parts. 



Apex of abdomen : Lobes barely indicated ; setae, apical 55-60 ix long, inter- 

 apical 9-12 ix long, a pair 1 \x long entad of interapical, intermediate and outer 

 ventral each about 4 /x long ; anal opening in ventral surface and margin, 

 elongate ; anal tube short, bulbous, sclerotized ; anal ring a semicircular or 

 circular sclerotized band, with 2 setae, each 5 fx long. 



Test of male. — Elongate ovoid, 1 mm. long, 0.5 wide; flat dorsally and 

 ventrally; pale greenish yellow, transparent, thin, punctate; marginal filaments 

 colorless, glassy. 



Adult male. — 0.85 mm. long. 



Head: Antenna 9-segmented ; formula (longest to shortest), (III), (IV), 

 (V, VI), (VII, IX), (VIII), (I), (II); antennal setae; I, 0; II, 10; III-IX, 

 6-10, IX also with 4 very long setae ; basal bars not apparent ; 6 or 8 setae 

 ventrally between eyespots and antennae; a minute sclerotized tubercle on 

 posterior lateral margin. 



Thorax : Bar between wing bases curved on anterior margin, slightly more 

 than twice as long as wide ; tibia as long as tarsus. 



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

 ently 4 or 5 segments each with a seta in ventral lateral area ; each lobe area 

 with 1 long and 3 short setae; penis sheath with 1 pair of setae dorsally at 

 base, 2 pairs ventrally at base, and 8 setae on each side of ventral opening. 



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



Third-stage male. — Similar to second stage but with legs represented by 3 

 pairs of faintly sclerotized, raised areas. 



Data. — Kedescribed from unmounted specimens and the following 

 mounted material collected by G. Compere : Three females, 5 second- 

 stage specimens, 4 poor larvae, 5 males, 1 male nymph, and 5 third-stage 

 males, on Petrophila linearis, Perth, West Australia, Compere No. 874; 

 15 females and 1 poor larva on Hake sp., Australia, March 1, 1902, 

 Compere No. 874. 



The larvae are unusual in not having marginal 8-shaped pores, in 

 apparently having only two ventral submarginal 8-shaped pores, and 

 in having only two minute setae on the anterior coxa, and only one on 

 each of the median and posterior coxae. 



Asterolecanium phoenicis Ramachandra Rao 



(Fig. 52, G-R; pi. 7, K) 



Described briefly by Eamachandra Kao in 1922 (78, p. 11), illus- 

 trated bv Dutt in 1922 (30, p. IS), and described in detail by Green in 

 1923 (1l7,pp.Jl69~1j70). 



Habit. — "On the leaf stalks, leaves and fruits of the date palm {Phoenix 

 daetijli-feraY' according to Green (47, p. 47>0) ; observed by the writer only on 

 the lower surface of leaves.
