THE SCALE INSECT GENUS ASTEROLECANTUM 59 



Asterolecanium captiosum, new species 



(Fig. 12, A-K; pi. 9. 8) 



Habit. — Living on the lower surface of leaves. 



Test of female. — Elongate. 1-1.25 nun. long, 0.5 wide; flat dorsally and ven- 

 trally, with a faint longitudinal median carina dorsally ; pale greenish yellow, 

 transparent, very thin; marginal filaments very pale yellow, slightly longer at 

 anterior end than elsewhere : elliptical larval exit in margin. 



Adult female. — Elongate. 0.9-1.10 mm. long, 0.4.1 wide. 



Margin: 8-shaped pores in a single row terminating slightly more thao length 

 of apical seta from setal bases, posterior pores 8-9 /x long and 4 wide, the 

 others 10 /x long and 4.5 wide, less than a pore's width apart: qiiinquelocular 

 pores in a single row from near antennae to about halfway between posterior 

 spiracular pore bands and the posterior pair of 8-shaped pores, as numerous as 

 8-shaped pores at ends of row, nearly or cpiite twice as numerous as 8-shaped 

 pores elsewhere. 



Dorsal surface: Minute 8-shaped and disk pores rather sparse; tubular ducts 

 24 ix long; dorsal tubes present. 



Ventral surface : Antenna very short, with 2 setae longer than diameter of 

 antenna ; beak without setae ; spiracular bar short and fairly slender ; 7-10 

 qiiinquelocular pores extending from spiracle to body margin in a single row : 1 

 or 2 dark-rimmed 8-shaped pores each side of beak, 3 or 4 anterior to mouth 

 parts and 5 or 6 in lateral area of abdomen; submarginal 8-shaped pores in a 

 single row terminating slightly posterior to the posterior pair of marginal 

 8-shaped pores, nearly as numerous as marginal 8-shaped pores : 4 pairs of 

 submarginal setae on abdomen, the posterior pair slightly nearer to the pos- 

 terior pair of marginal 8-shaped pores than to bases of apical setae; 1 pair of 

 setae posterior to genital opening, 1 pair anterior to opening, and 1 pair anterior 

 to the latter. 



Apex of abdomen: Slightly concave and with a small notch: lobes indicated: 

 setae, apical 44 fx long, interapical 6-7.2 /x long, outer ventral 2 jx long : anal ring 

 with 2 setae apparently 14.4 \x long and four 18 /x long and apparently with VI 

 pores not arranged in definite rows, not noticeably divided ; ventral surface 

 between lobes slightly sclerotized and rugose. 



Data. — Described from unmounted material and four mounted fe- 

 males on Baimbusa sp., Antipole Luzon. Philippine Islands. A. S. 

 Hitchcock. June 9, 1921. U. S. N. H.. holotvpe and paratypes. 



This species resembles abieetum. but has three pairs of setae instead 

 of four on the apex of the abdomen. It is closely related to amboina* . 

 but does not have dorsal 8-shaped pores. In each of these species the 

 marginal 8-shaped pores are conspicuously long and slender. 



Asterolecanium castaneae, new species 



(Fig. 12, L-Y; pi. 8, R) 



Habit. — Living on bark, in pits. 



Test of female.— -Ovoid or nearly circular. 0.75-1 mm. long, 0.6-0.75 wide, or 

 around 0.75 mm. in diameter: dorsally slightly to conspicuously convex with 

 posterior tip flattened and slightly produced, with or without faint median 

 and lateral carinae and faint transverse striations, flat or slightly convex 

 ventrally; greenish yellow, transparent to semitransparent, often shiny ; marginal 

 filaments pale salmon to nearly white, slightly shorter at posterior end than 

 elsewhere; elliptical larval exit in dorsal surface at margin. 



Adult female. — Usually ovoid, sometimes circular, posterior end usually 

 slightly produced; 0.7-0.9 mm. long. 0.5-0.7 wide, or around 0.65 mm. in 

 diameter. 



Margin: 8-shaped pores in a single row terminating two to three times 

 a pore's length from bases of apical setae, each pore with a sclerotized tongue- 

 shaped projection on dorsal edge (often inconspicuous it" weakly stained), 

 posterior pores 7 /x long and 4 or 5 wide, the others 8-9 u long and 5 wide, 

 usually a pore's length apart; quinquelocular pores in a single row (sometimes
