Asterolecanium javae, new species 



(Fig. 34, L-Oj fig. 35, A-G ; pi. 9, JB7) 



Habit. — Living on stems. 



Test of female. — Nearly circular, 1.25 mm. in diameter, posterior end slightly 

 produced ; slightly raised dorsally, with a faint longitudinal median carina not 

 extending to margin, with faint curved lateral carina e not extending to margins 

 or to median carina, and with faint transverse striations ; flat ventrally ; brown- 

 ish yellow, transparent, fairly thin, slightly punctate ; marginal filaments whitish, 

 fragmentary ; dorsal filaments rubbed off, presumably occurring over most of 

 test in unrubbed specimens ; circular larval exit in ventral surface at margin. 



Adult female. — Similar to test in shape, 1 mm. in diameter. 



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

 of apical seta from setal bases, posterior pores 10 m long and 7 wide, others 13 m 

 long and 9 wide, less than a pore's width apart ; quinquelocular pores in a single 

 row terminating at the posterior pair of 8-shaped pores, at least one and one-half 

 times as numerous as 8-shaped pores. 



Dorsal surface: 8-shaped pores fairly numerous along median line and in 

 submarginal and lateral areas, anterior median and a few lateral pores 13-16 /x 

 long and 9-10 wide, majority of lateral pores 12 //. long and 8 wide, a few 10 fi 

 long and 7 wide ; minute 8-shaped pores very numerous ; disk pores fairly numer- 

 ous ; tubular ducts 26 fi long. 



Ventral surface : Antenna dome-shaped, with 2 setae longer and 2 or 3 much 

 shorter than diameter of antenna ; 3 quinquelocular pores between antenna and 

 margin; beak with 2 pairs of setae; spiracle with bar subcircular and 32 n wide, 

 with area around opening slightly raised and containing 15-20 quinquelocular 

 pores, and with 10-13 similar pores extending to body margin in a single row, 

 25-30 in group and row combined ; multilocular pores with 10 loculi, apparently 

 arranged in 4 complete and certainly in 5 interrupted rows, the anterior row 

 anterior to posterior spiracles, posterior row with 12 pores, penultimate with 16, 

 next with 19. next with 12, and each of interrupted rows with 2-6 ; 3 or 4 dark- 

 rimmed 8-shaped pores each side of mouth parts, many scattered elsewhere ; 

 submarginal 8-shaped pores in a single row, apparently terminating near the 

 posterior pair of marginal 8-shaped pores and about as numerous as those pores; 

 disk pores in a submarginal row among submarginal 8-shaped pores, terminating 

 about halfway between the posterior pair of marginal 8-shaped pores and bases 

 of apical setae, less numerous than marginal 8-shaped pores ; submarginal setae 

 in a complete row terminating slightly nearer to the posterior pair of marginal 

 8-shaped pores than to bases of apical setae ; apparently 2 pairs of setae in 

 posterior row, and possibly 1 pair in penultimate row of multilocular pores. 



Apex of abdomen : Notch present ; lobes indicated ; setae, apical 80 /n long, 

 interapical 9 /* lon^, dorsal 12.6 fi long, inner ventral 3.6 n long, intermediate 

 ventral 3.6 fi long, outer ventral 7.2 fx long; anal ring with 6 setae 32-34 /* long 

 and with an inner row of 6 and an outer one of apparently 14 pores, divided 

 on dorsal side and tending toward division on ventral ; ventral surface of apex 

 heavily sclerotized in a roughly rectangular area extending anteriorly from 

 interapical setae. 



Larva. — Elongate ovoid. 



Margin : With 28 8-shaped pores, posterior and anterior pairs slightly larger 

 than others, axes of the posterior 6 pairs transverse, of the others longitudinal ; 

 apparently 3 pairs of setae at anterior end. 



Dorsal surface: 8-shaped pores in a submedian row of 7 or 8 and a lateral 

 row of 9, on each half of body, the posterior pores of each row slightly smaller 

 than anterior ones, posterior submedian pores slightly smaller than, anterior 

 ones same size as, marginal pores of same segments ; lateral pores slightly larger 

 than marginal pores of same segments ; disk pores between submedian and 

 lateral 8-shaped pores and a few between lateral and marginal 8-shaped pores ; 

 a pair of minute setae anterior to the anterior pair of pores of the submedian row. 



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

 stout ; antennal bases about one-half length of antenna apart ; beak setae, 2 pairs 

 apical, 1 pair basal ; spiracle with 1 trilocular pore ; leg setae, coxa 4, femur 

 1 on inner margin near base and 1 on outer margin near center, tarsus 2 on 

 inner and 1 on outer margin; tibia about one-half as long as tarsus; 10 pairs 

 of submarginal 8-shaped pores ; disk pores in a submarginal row near submar- 

 ginal 8-shaped pores, apparently as numerous as 8-shaped pores ; 7 pairs of
