DESCRIPTIONS 



Asterolecanium abiectum, new species 



(Fig. 2, A-I; pi. 7, L) 



Habit. — Living on both surfaces of leaves. 



Test of female. — Elongate elliptical, 1.5-2 mm. long. 0.75-1 wide; flat dorsally 

 and ventrally. with a faint longitudinal median carina dorsally; pale yellow, 

 transparent, thin, finely punctate; marginal filaments usually deep salmon; 

 larval exit a slit in margin. 



Adult female. — Elongate elliptical, posterior end slightly produced; 1.3-1.8 

 ram. long, 065-0.95 wide. 



Margin: 8-shaped pores in a single row terminating around length of apical 

 seta from setal bases, the individual pores about 14 p long and 5 (> wide, usually
