ASTEROLECANIUM BRUNETAE, new Species 



(Fig. 11, B-L; pi. 9, Z) 



Habit. — Living on the lower surface of leaves. 



Test of female. — Slightly longer than wide, posterior end produced and 

 turned up against dorsal surface : 0.75-0.95 mm. long, 0.6-0.75 wide ; convex 

 dorsally, sides slightly curved, top flat with a faint longitudinal median carina 

 and faint transverse striations, flat ventrally ; pale yellow, transparent, thin, 

 slightly punctate ; marginal filaments pale yellow, very short, fragmentary ; 

 dorsal filaments rubbed off; elliptical larval exit at tip of produced area in 

 dorsal surface. 



Adult female. — Slightly longer than wide, posterior end slightly produced; 

 about 0.75 mm. long, 0.6 wide. 



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

 times the length of apical seta from setal bases, measuring 6 //. long and 4 wide, 

 four to seven (usually six) times a pore's length apart. 



Dorsal surface : 8-shaped pores 14-16 in number, occurring at fairly uniform 

 intervals in submarginal area, 8-10 fi long and 6-8 wide, posterior pores as large 

 as any ; minute 8-shaped pores not observed ; disk pores fairly numerous ; tubular 

 ducts 28 fi long; dorsal tubes present. 



Ventral surface : Antenna globular, with 2 setae slightly longer than diameter 

 of antenna ; beak without setae ; spiracular bar fairly broad ; 1 quinquelocular 

 pore close to spiracular opening and 2-4 near body margin ; 1 or 2 dark-rimmed 

 8-shaped pores each side of beak, a few on anterior end, and a few in 2 trans- 

 verse rows near posterior end of abdomen ; submarginal 8-shaped pores in a 

 single row terminating slightly anterior to genital opening, placed at uniform 

 intervals equivalent to slightly more than the length of a marginal 8-shaped pore, 

 usually at least twice as numerous as marginal 8-shaped pores; 5 pairs of sub- 

 marginal setae on abdomen, the posterior pair closer to bases of apical setae than 

 to the posterior pair of marginal 8-shaped pores ; 1 pair of setae posterior to 

 genital opening, 1 pair anterior to opening, and 1 pair anterior to those. 



Apex of abdomen : Lobes indicated ; setae, apical 54 n long, interapical 7.2 fi 

 long, inner ventral 3.6 ^ long, outer ventral 4 fi long ; anal ring with 6 setae, each 

 about 27 fi long, with an inner row of 6 and an outer one of 12 pores, and with 

 a tendency toward division on ventral side ; ventral surface of apex slightly 

 sclerotized and rugose. 



Larva. — Elliptical. 



Margin : With 28 8-shaped pores, anterior pair slightly the largest, axes of 

 the posterior 3 pairs diagonal or longitudinal, the others longitudinal ; 2 pairs 

 of setae anteriorly. 



Dorsal surface : 8-shaped pores in a submedian row of 2 or 3 on each half of 

 body, posterior pore much smaller than middle pore when this is present and mid- 

 dle pore slightly smaller than anterior, which is a little smaller than marginal 

 pores of same segment ; disk pores in lateral area and a few near margin. 



Ventral surface : Antennal setae, I, 1 ; IV, 1 ; V, 1 ; VI, 2 long, 2 stout, 3 fairly 

 stout, 1 slender ; beak setae, 2 pairs apical, 1 pair median ; spiracle apparently 

 with 1 trilocular pore ; leg setae, coxa 4, femur 1 on inner margin near base and 

 1 each on inner and outer margins near center, tarsus 2 on inner and 1 on outer 

 margin ; tibia one-half as long as tarsus ; 9 pairs of submarginal 8-shaped pores ; 

 6 pairs of submarginal minute setae on abdomen, 3 pairs of submarginal larger 

 setae at anterior end ; 2 pairs of setae near antennae. 



Apex of abdomen : Lobes indicated ; setae, apical 29 fi long, interapical 5.4 fi 

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

 each about 3.6 n long. 



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

 and three mounted larvae on Bambusa sp., Antipolo, Luzon, Philippine 

 Islands, A. S. Hitchcock, June 9, 1921, U. S. N. H., holotype and 

 paratypes. 



Closely related to parvurn, but differing from it in lacking marginal 

 quinquelocular pores and in having tubular ducts 28 instead of 12 fi 

 long.
