Apex of abdomen: Notch present; setae, apical 81 m long, interapical 12.0 ^ 

 long, inner ventral 5.4 ft long, outer ventral 3.6 /x long; anal ring with 6 

 about 12.6 ft long and an inner row of 6 and an outer of apparently 8 i

Data. — Redescribed from the following material identified on the 

 basis of Kuwana's original description: Unmounted specimen-, two 

 mounted female-, and six mounted larvae on Bambusa metake^ River- 

 ton. X. J.. H. B. Weiss, May 1916: one mounted female on Phyl- 

 lostaehys sp.. Lung T'au Shan. Ping Shan Hang. K'uk Kong district, 

 Kwangtung. China. F. A. McClure, January 10. 1926; one test and one 

 mounted female on Arundinaria chino, Sendai. Japan. E. Iishiba. May 

 16. 1926. N. Y. B. G. 



This is the only known species on bamboo in which the marginal 

 8-shaped pores are in a double row. 



Asterolecanium hilli Green 



(Fig. 30, F-M ; pi. o. /) 



Described in 1916 (j.5. pp. 63-6%). 



Habit. — Living on the lower surface of leaves. 



Test of female. — Elongate elliptical. 2.25 mm. long and 0.95 wide, posterior 

 end narrowed ; nearly flat to slightly convex dorsally, flat ventrally ; clear 

 yellow, transparent, thin, punctate: marginal filaments whitish, fragmentary; 

 circular larval exit in dorsal surface at the margin. 



Adult female. — Nearly elongate elliptical, 2 mm. long, ".75 wide, posterior 

 end narrowed and slightly constricted. 



Margin : 8-shaped pores in a single row terminating near constriction in body, 

 or about twice length of apical seta from bases of setae. 9 u lung and 4 wide, 

 the pores normally about a pore's length apart: trilocnlar pores in a single row 

 between spiracular pore bands and extending about 15 pores outside them, 1 or 

 2 near each 8-shaped pore. 



Dorsal surface: Minute 8-shaped pores not observed; disk pores sparse: 

 tubular ducts 28 /j. long. 



Ventral surface: Antenna short, apparently with 2 setae slightly longer than 

 diameter of antenna: beak with 2 pairs of setae: spiracle with bar expanded 

 at inner end. opening broad, atrium somewhat enlarged and containing 2 

 trilocnlar or quinquelocular pores, approximately 15 trilocnlar pores extending 

 from spiracle to body margin in a single row: multilocular pores, having 6-10 

 loculi (usually 10 1 . arranged in 3 complete rows, posterior row with 30 pores, 

 middle row with 20. and anterior row with 10: 2 dark-rimmed 8-shaped pores 

 each side of beak. 4 on anterior end. and 4 near posterior end: submarginal 

 8-shaped pores at loast as numerous as marginal 8-shaped pores, in a double 

 row terminating near anal opening, inner pores larger and usually less numerous 

 than outer ones: apparently 6 pairs of submarginal setae, observed only pesterior 

 to spiracles, the posterior pair about two-thirds the length of an apical seta 

 from bases of apical setae: 2 pairs of setae in posterior row of multilocular pores 

 and 1 pair in each of the other rows. 



Apex of abdomen: Setae, apical (on ventral surface near margin) 00 u. long, 

 interapical (also on ventral surface) 3.6 /j. long, outer ventral 3 ,u long: anal 

 opening ventral, anterior to bases of apical setae, circular, its margin faintly 

 sclerotized. 



Larva. — Elongate elliptical. 



Margin: With 28 elongate, slender 8-shaped pores, which gradually increase 

 in size from posterior end of row. axes of all longitudinal: a pair of minute 

 setae close to each of the posterior 3 pairs of pores; •"> pairs of setae anteriorly. 



Dorsal surface: 8-shaped pores in a lateral row of 9 on each half of body, 

 shorter than the width of a posterior marginal pore: disk pores between lateral 

 and marginal 8-shaped pores. 



Ventral surface: Antenna! setae. 1. 1 : IV. 1 : V. 1 : VI. 2 long, 2 stout. :; fairly 

 stout. 1 slender: antenna] bases one-half length of antenna apart: beak setae. 1
