minute setae on abdomen, 1 pair of submarginal larger setae at anterior end ; 3 

 pairs of setae between antennae and mouth parts. 



Apex of abdomen : Setae, apical 45 /* long, interpieal 7.2 /* long, outer ventral 



2 fi long; anal opening apical; anal tube very short, slightly sclerotized, some- 

 what bulbous; anal ring a sclerotized band, its ventral side nearly on surface, 

 with 2 setae 4-5 v long. 



Data. — Described from unmounted material, nine mounted females, 

 and two mounted larvae from Lithocarpus sp., Suislia, Taiwan 

 (Formosa), E. Takahashi, September 1928, holotype and paratypes. 



Closely related to pasaniae, but differing from it in lacking a scle- 

 rotized, tongue-shaped projection from the marginal 8-shaped pores, 

 in having 57 to 68 instead of around 36 multilocular pores, and in 

 having a double, instead of a single, row of submarginal 8-shaped 

 pores. 



Asterolecanium sumatrae, new species 



(Fig. 70, F-L; fig. 71, A) 



Habit. — Living on the upper surface of leaves. 



Test of female. — Slightly longer than wide, around 3 mm. long and 2.5 wide ; 

 flat dorsally and ventrally ; yellow, transparent, thin, shiny, punctate ; marginal 

 filaments pale golden, fragmentary ; dorsal filaments rubbed off ; circular larval 

 exit in ventral surface at margin. 



Adult female. — Slightly longer than wide, around 2.5 mm. long, 2 wide. 



Margin : 8-shaped pores in a single row terminating two-thirds length of an 

 apical seta from setal bases, the posterior pores 9-10 m long and 5 wide and the 

 others 11-12 n long and 7-8 wide, around a pore's length apart ; quinquelocular 

 pores mostly in a single row, but sometimes in a double row near spiracular pore 

 bands, terminating near the posterior or penultimate pair of 8-shaped pores, at 

 least twice as numerous as corresponding 8-shaped pores except near spiracular 

 pore bands, where they are four times as numerous as 8-shaped pores. 



Dorsal surface : 8-shaped pores in at least 10 groups of 7-12 pores each, along 

 median line (derm torn anterior to mouth parts and presence or absence of other 

 median pores indeterminable), and in 22 groups (1-5 pores in each of the posterior 



3 groups, 10-14 in each of the others) in submarginal area, majority of pores 8 /* 

 long and 6 wide, a few 6-7 n long and 4-5 wide ; minute 8-shaped pores numerous ; 

 disk pores fairly numerous ; tubular ducts 18 /jl long. 



Ventral surface: Antenna thimble-shaped, with numerous minute papillalike 

 excrescences, presence or absence of long setae indeterminable ; beak appar- 

 ently without setae ; spiracular bar broad ; a group of 5-7 quinquelocular pores 

 outside spiracular opening and 45-55 similar pores extending from group to 

 body margin in a triple or quadruple row ; multilocular pores, totaling about 

 105 and with 8-10 loculi, in 3 complete and apparently 8 interrupted rows 

 (interrupted rows irregularly disposed and exact number indeterminable), 17-25 

 pores in each complete row, 3-7 in each interrupted row ; 6 dark-rimmed 

 8-shaped pores each side of beak, some scattered on anterior end, and others 

 tending toward arrangement in 3 or 4 transverse rows among multilocular pores; 

 submarginal 8-shaped pores in a triple row terminating near the posterior row 

 of multilocular pores, at least twice as numerous as corresponding marginal 

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

 penultimate pair of marginal 8-shaped pores; 2 pairs of setae each in the 

 posterior and penultimate rows of multilocular pores. 



Apex of abdomen : Notch present ; lobes strongly developed ; setae, apical 

 (tips broken) 63 y. long, interapical 11 fi long, outer ventral 9 n long; anal ring 

 with 6 setae 32 /* long and apparently with an inner row of 6 and an outer row 

 of 14 pores, apparently not divided : ventral surface of apex slightly sclerotized. 



Larva. — Apparently elongate ovoid. 



Margin: With 28 8-shaped pores, the anterior pair slightly larger than the 

 others, axes of all longitudinal ; apparently 2 pairs of setae at anterior end. 



Dorsal surface: 8-shaped pores in a submedian row of 10 and a lateral row 

 of 12, on each half of body, 3 pores of lateral row outside a straight lateral 

 line and suggesting a submarginal row, pores of submedian row gradually 

 increasing in size from posterior pore to the second from anterior end, about
