THE SCALE IXSECT GENUS ASTEROLECAXIUM 65 



Data. — Redescribed from one test, two mounted females, one mounted 

 second-stage specimen, and one mounted third-stage male on bamboo. 

 Hewaheta. Ceylon. E. E. Green. March 1910. 



The test available for study is in such condition that little of value 

 can be added to Green's excellent description, but it should be noted 

 that the sides, though nearly perpendicular, curve from the dorsum 

 rather than being demarked by an "angular marginal li 



The species is unusual morphologically. The presence of quinque- 

 locular pores on each side of the marginal 8-shaped pores has not 

 been observed elsewhere in the genus and the presence of relatively 

 large 8-shaped pores on the ventral surface has been observed rarely. 

 Green associated the 8-shaped pores with the dorsal surface. In all 

 adult females at hand, however, there are no 8-shaped pores on the 

 dorsal surface although they do occur on the ventral surface. Green 

 stated ($?, p. S2Jf). "anal ring apparently hairless, at the base of a 

 remarkable funnel-shaped chitinous tube." The ring has two setae, 

 however. 



Asterolecanium chinae, new species 



(Fig. 14, A-I; pi. 6, E) 



Habit. — Living on the lower surface of leaves. 



Test of female. — Somewhat elongate ovoid, tapering strongly from center to 

 posterior tip, 1.75-2.25 mm. long, 1.10-1.45 wide ; nearly flat dorsally, with a faint 

 longitudinal median carina, flat ventrally : brownish or very pale yellow, trans- 

 parent, thin, slightly punctate ; marginal and dorsal filaments whitish, the 

 latter fragmentary, present in submarginal and a few in lateral or median 

 areas : elliptical larval exit in margin. 



Adult female. — Somewhat elongate ovoid, tapering rather strongly from center 

 to posterior tip, or not tapering strongly from center, but with posterior tip 

 narrowed and produced : 1.25-2 mm. long, 1-1.25 wide. 



Margin: 8-shaped pores in a single row terminating about a posterior pore's 

 width from bases of apical setae, anterior pores around 14.4 fi long and 9 wide, 

 the others around 10.8 /j. long and 7.2 wide, interspaces usually less than the 

 width of a pore but occasionally equal to the length of a pore; quinquelocular 

 pores in a single row normally terminating at the posterior or penultimate pair 

 of 8-shaped pores, usually as numerous as 8-shaped pores; disk pores dorsad of, 

 and terminating with, the 8-shaped pores, about as numerous as those pores. 



Dorsal surface: 8-shaped pores distributed in submarginal and lateral areas 

 and a few in median area, tending toward arrangement in indefinite transverse 

 rows. 29 and 112 the greatest range noted, some 10.8 m long and 7.2 wide, but 

 the majority about 14.4 fi long and 9 wide ; minute 8-shaped and disk pores 

 numerous ; tubular ducts 36-40 ,u long : dorsal rubes present. 



Ventral surface: Antenna short, with 2 setae longer and 1 or 2 shorter than 

 diameter of antenna; beak without setae: spiracular bar fairly broad: anterior 

 spiracle with 13-26 quinquelocular pores extending to body margin, usually in a 

 loose group near opening, then in an irregularly single row but usually in a 

 triple row at margin: posterior spiracle with 3-7 quinquelocular pores in a loose 

 group around opening, rarely with 1 or 2 at intervals between group and body 

 margin; multiloeular pores, totaling G3-76 and with 10 loculi. in 5 complete rows 

 (1 of which is sometimes interrupted) and in 2. or sometimes in 3, interrupted 

 rows, posterior row with 10-16, penultimate with 15-21, next with 16 23, next 

 with 7-12. next with 2-6. and each of next 2 or 3 with 1-3; none or 1 dark- 

 rimmed 8-shaped pore each side of beak, a few scattered anterior to mouth parts. 

 a few in lateral area of abdomen, and others arranged in 4 or 5 transverse rows 

 among multiloeular pores; submarginal 8-shaped pores in a slightly irregular 

 single row terminating near posterior row of multiloeular pores, nearly or quite 

 as numerous as marginal 8-shaped pores; 5 pairs of submarginal setae on 

 abdomen, the posterior pair 3 or 4 8-shaped pores from the posterior pair of 

 marginal 8-shaped pores: 1 pair of setae in each of the posterior 3 rows of 

 multiloeular pores.
