ASTEROLECANIUM BAMBUSICOLA Kuwana 



(Fig. 7, H-P; pi. 2, A) 



Described in 1916 (55, pp. lJfi-lJfl) . Asterolecanium tuberculatum, 

 described by Takahashi as a variety of bambusae in 1928 (91, p. 339) 

 and elevated to specific rank in 1929 (92, pp. 8, 46) , is here suppressed 

 because specimens of tuberculatum studied, which are presumed to be 

 type material, are identical with bambusicola. 



Habit. — Living on stems. 



Test of female. — Nearly elongate elliptical, 2.5-3.5 mm. long, 1.25-1.5 wide ; 

 convex dorsally, with a broad, transverse, prominent carina immediately an- 

 terior to transverse median line, the surface gradually sloping from carina to 

 margin, sometimes also with a faint longitudinal median carina ; strongly con- 

 cave or nearly flat ventrally ; greenish or clear yellow, transparent, thin, shiny ; 

 marginal filaments pinkish ; elliptical larval exit in ventral surface at margin. 



Adult female. — Nearly elongate elliptical, 2-3 mm. long, 1-1.5 wide. 



Margin: 8-shaped pores in a single row terminating a pore's length from bases 

 of apical setae, 14 /* long and 8 wide, less than a pore's width apart ; quinque- 

 locular pores in a single or an irregularly double row, terminating at or slightly 

 beyond the posterior pair of 8-shaped pores, as numerous as 8-shaped pores near 

 ends of body, more numerous near center, and two to four limes as numerous as 

 8-shaped pores between spiracular pore bands ; disk pores dorsad of 8-shaped pores, 

 terminating at the posterior pair of those pores and about as numerous. 



Dorsal surface : Minute 8-shaped pores rather numerous ; disk pores numerous ; 

 tubular ducts about 9 //. long ; dorsal tubes present. 



Ventral surface: Antenna short, rough, with 2 setae longer and 3 slightly 

 shorter than diameter of antenna; 5 or 6 quinquelocular pores between antenna 

 and margin; beak without setae; spiracular bar subcircular; 60 1'H) (usually 

 90-100) quinquelocular pores extending from spiracle to body margin in a row 

 3-8 pores wide; 5-12 dark-rimmed 8-shaped pores each side o\' month parts, 

 others in a longitudinal row 3 pores wide in lateral area of abdomen; submar- 

 ginal 8-shaped pones in a single row terminating 3 5 8-sh;!ped pores from the 

 posterior pair of marginal 8-shaped pores and one-half as numerous as those 

 pores; 6 pairs of submarginal setae on abdomen, the posterior pair 3 8-shaped 

 pores from the posterior pair of marginal 8-shaped pores; a group of 8 13 setae 

 posterior to genital opening, a group of 4-7 anterior to opening, and another group 

 of 2-4 anterior to that group. 



Apex of abdomen: Notch present : lobes indicated: setae, apical 90 It',) u long, 

 interapical 8 n long, inner ventral 8 jjl long, outer ventral 9-10 p long: anal riniE
