THE SCALE INSECT GENUS ASTEROLECANIUM 71 



The filaments of available tests are whitish or yellowish instead of 

 reddish, as stated by Brain (12, p. 112). 



This species is more closely related to cojfeae than to other known 

 species. Both are unusual in having what appears to be an interme- 

 diate ventral seta unaccompanied by an outer ventral seta. 



Asterolecanium corallinum Takahashi 



(Fig. 16, B-M; pi. 9. J/) 



Described in 1928 (OL pp. 339-31fi). 



Habit. — Living on bark, in shallow pits. 



Test of female. — Slightly longer than wide, about 1.4 mm. long, 1 wide; 

 slightly convex dorsally. with a faint longitudinal median carina and faint trans- 

 verse striations, slightly convex ventrally ; greenish yellow, transparent, thin, 

 punctate; marginal filaments pale salmon, slightly shorter near posterior end 

 than elsewhere; dorsal filaments whitish, very short (possibly broken), and 

 sparse ; elliptical larval exit in margin. 



Adult female. — Longer than wide, 1-1.3 mm. long, 0.75-1 wide. 



Margin : 8-shaped pores in a single row terminating around twice a pore's 

 length from bases of apical setae, posterior pores 11-12 y, long and 8 wide, the 

 others 12-13 y long and 8-9 wide, usually a pore's width apart ; quinquelocular 

 pores in a single row terminating at the posterior pair of 8-shaped pores, at 

 least as numerous as 8-shaped pores near ends of body and usually slightly more 

 than twice as numerous elsewhere. 



Dorsal surface : 8-shaped pores in median and submarginal areas, tending 

 toward arrangement in transverse rows, fairly numerous, about 10 u long and 

 8 wide: minute 8-shaped pores numerous: disk pores rather sparse; tubular 

 ducts 28 /jl long. 



Ventral surface: Antenna short, rounded, sunken in derm, with 2 setae slightly 

 longer, and apparently 5 much shorter, than diameter of antenna ; 3 or 4 quin- 

 quelocular pores between antenna and margin: beak with 2 pairs of setae; 

 spiracle with bar nearly circular and with lines extending around opening, the 

 lined area sometimes slightly sunken and containing 7-15 quinquelocular pores, 

 15-25 similar pores extending to body margin in an irregularly single or double 

 row, a total of 23-37 in group and row combined: legs represented by 3 pairs 

 of small sclerotized areas each with a slightly curved, short, rather stout claw, 

 2 or 3 minute setae, and many clear areas suggestive of setal bases; multilocula r 

 pores, totaling 95-106 and having 6-11 (usually 10) loculi. in 9 rows, of w 

 5 or 6 are complete and 3 or 4 are interrupted, anterior row anterior to posterior 

 spiracles, posterior and penultimate rows each with 8-12. next with 14- in. 

 next with 18-22. each of next 2 with 9-13, each of next 2 with 8 or 9. and 

 anterior row with 2-5: 2-6 dark-rimmed 8-shaped pores each side of beak, a 

 few scattered anterior to mouth parts, and a few tending toward arrangement 

 in 5 or 6 transverse rows on abdomen; submarginal 8-shaped pores in a single 

 row terminating 3 or 4 8-shaped pores from the posterior pair of marginal 8-shaped 

 pores, usually as numerous as marginal 8-shaped pores; submarginal disk pores 

 in a single row interspersed among submarginal 8-shaped pores, and terminating 

 anterior to the posterior pair of those pores, not nearly so numerous as sub- 

 marginal 8-shaped pores: submarginal setae in a complete row terminating near 

 the posterior pair of marginal 8-shaped pores: 5 setae in posterior row of 

 in unilocular pores and 2 in penultimate row. 



Apex of abdomen: Notch present; lobes indicated; setae, apical 72-74 m long. 

 interapical 10.8 fi long, dorsal 12.6 n long, inner ventral 5.4 u long, intermediate 

 ventral 5.4 /x long, outer ventral 9 y long: anal ring with setae 27-30 a Long 

 and with an inner row of and an outer one of 14 pores, divided ow dorsal - 

 ventral surface with an irregularly rectangular area between lobes, strongly 

 sclerotized in dentate rows, the surrounding area faintly sclerotized in slightly 

 dentate rows. 



Data. — Redescribed from unmounted material and four mounted 

 females, apparently on Sid&rosoylon ferrugmewm, Keelung, Taiwan 

 (Formosa ). R. Takahashi, August 1. 1927, presumably cotype material. 



This species is closely related to javcu and psychotricu and rather so 

 to pustulans; it may also he related" to loram&hi, but the dorsal 8-shaped 

 pores of that species are the same size as the marginal.
