Ventral surface : Antenna thimble-shaped, with 1 or 2 setae mnch shorter and 2 

 slightly longer than diameter of antenna ; beak without setae ; spiracular bar 

 subcircular ; 2 or 3 quinquelocular pores nearer spiracle than body margin ; legs 

 represented by 3 pairs of stout claws; multilocular pores, totaling 70-81 and 

 with 8-10 loculi, in 5 complete and 3 or 4 interrupted rows (often 3 interrupted 

 rows on 1 half of body and 4 on the other), the anterior row anterior to posterior 

 spiracles, each of posterior 5 rows with 9-14 pores, each of the others with 2-7 ; 

 dark-rimmed 8-shaped pores scattered and sparse: submarginal 8-shaped pores 

 mostly in a single row but in a double row at posterior end, terminating near 

 posterior row of multilocular pores, about half as numerous as corresponding 

 marginal 8-shaped pores ; submarginal setae in a complete row terminating near 

 penultimate pair of marginal 8-shaped pores ; 2 pairs of setae in posterior row of 

 multilocular pores and 1 pair in penultimate row. 



Apex of abdomen : Lobes indicated ; setae, apical 72 fx long, interapical 10.8 n 

 long, intermediate ventral 3.6 /j. long, outer ventral 7.2 n long ; anal ring with 6 

 setae 28 m long and with an inner row of 6 and an outer one of 14 pores, divided 

 on dorsal and ventral sides ; ventral surface of apex with an irregularly sclerotized 

 area anterior to each interapical seta, area between these sometimes slightly 

 sclerotized in dentate rows. 



Second stage. — Resembling adult female but distinctly longer than wide : dorsal 

 surface without 8-shaped pores ; apex of abdomen as in adult but all setae about 

 one-fourth shorter. 



Test of male. — Elliptical, 1 mm. long, 0.6 wide; dorsally slightly convex at 

 anterior end, sloping to posterior end ; flat ventrally ; pale greenish yellow, trans- 

 parent, very thin, punctate, shiny; marginal filaments pale yellowish, slightly 

 longer at anterior end than elsewhere ; dorsal filaments brownish, occurring along 

 median line and in lateral area. 



Adult male. — 1 mm. long. 



Head: Antenna 10-segmented : formula (longest to shortest). (X), (II). (IV. 

 V), (VI), (VII, VIII). (IX), (I, II) ; antennal setae, I, 11; II, III, 15 or 16; IV, 

 V, 19 or 20 ; VI, VII, 25-27 : VIII, IX, 21 or 22 ; X, 29 slender, 3 stout, and 3 

 apparently rather long ; basal bars diagonal ; 30 setae between ventral eyespots 

 and antennae ; 2 setae on dorsal surface. 



Thorax: Bar between wing bases rectangular, with a longitudinal fold and a 

 clear area in center, four times as long as wide ; tibia one-fifth shorter than tarsus. 



Abdomen : Five segments each with a seta dorsally on lateral margin. 2 segments 

 each with a seta in ventral submedian area ; each lobe area with 1 long and 3 

 short setae ; penis sheath with 1 pair of setae dorsally near base and 6 setae on 

 each side of ventral opening. 



Data. — Described from specimens (13 females, 1 second-stage speci- 

 men, and 1 adult male, mounted) on Durio zibethinus, Botanic Garden, 

 Singapore, Straits Settlements, I. H. Burkill, April 3, 1922, holotype 

 and paratypes. and unmounted material and 1 mounted female from 

 Durio sibethinus, Java. A. Zimmermann collector, from E. E. Green, 

 received in 1933, paratypes. 



Of the known species not living on bamboo, ungulatum and epidendri 

 are the only ones having six setae on the anal ring in which setae have 

 not been observed on the beak. 



Asterolecanium unicum, new species 



(Fig. 77, B-F) 



Habit. — Living on the upper surface of leaves. 



Test of female. — Elongate, sides nearly parallel, tapering near ends ; 2.5 mm. 

 long, 0.7 wide ; strongly and sharply convex dorsally. flat ventrally ; pale yellow, 

 transparent, punctate, shiny ; marginal filaments same color as test ; circular 

 larval exit in margin. 



Adult female. — Elongate. 2.25 mm. long, 0.6 wide. 



Margin : 8-shaped pores in a single row terminating around one and a half 

 times the length of an apical seta from setal bases, 8 /j. long and 5 wide, from 

 the width to twice the length of a pore apart ; trilocular pores in a single row 

 opposite about 30 8-shaped pores on lateral margins, 1 opposite every other 

 8-shaped pore at ends of row, about twice as numerous in middle of row.
