Adult female. — Similar to test in shape, about 1.3 mm. long and 1.10 wide, or 

 1.10 mm. in diameter. 



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

 from bases of apical setae, posterior pores 10 /x long and 6 wide, the others 

 12-13 n long and 8-9 wide, a pore's width apart at anterior end, usually less than 

 that elsewhere ; quinquelocular pores in a single row terminating at the posterior 

 pair of 8-shaped pores, usually about as numerous as 8-shaped pores near 

 posterior end of row, more numerous elsewhere. 



Dorsal surface : Minute 8-shaped pores very numerous ; disk pores fairly numei 

 ous ; tubular ducts 30 /x long. 



Ventral surface : Antenna rough, irregular, sharply conical, sunken in derm, 

 apparently with 4 (possibly more) setae shorter, and 2 slightly longer, than 

 diameter of antenna ; 3-10 quinquelocular pores between antenna and margin ; 

 beak with 2 pairs of setae; spiracular bar subcircular ; derm outside spiracular 

 opening faintly sclerotized and containing 13-24 quinquelocular pores, 23-32 ad- 

 ditional pores extending to body margin in an irregularly single to triple row, 

 a total of 37-49 pores in group and row combined ; multilocular pores, totaling 

 137-153 and having 8-10 loculi, apparently arranged in 6 complete and 3 inter- 

 rupted rows, the anterior row anterior to posterior spiracles, posterior and 

 penultimate rows each with 12-16 pores, next row with 22-26, each of next 2 with 

 23-33, next with 9-16, posterior 2 interrupted rows each with 7-12, and anterior 

 interrupted row with 4 ; 2-5 dark-rimmed 8-shaped pores each side of beak, a 

 few scattered on anterior end, some arranged in rather indefinite longitudinal rows 

 in lateral area, and others tending toward arrangement in 5 or 6 transverse 

 rows posterior to mouth parts : submarginal 8-shaped pores usually in an 

 irregular single row terminating near the penultimate or posterior pair of mar- 

 ginal 8-shaped pores, nearly as numerous as marginal 8-shaped pores ; submarginal 

 disk pores in a single row interspersed with submarginal 8-shaped pores and 

 terminating nearly directly anterior to apical setae ; submarginal setae in a com- 

 plete row terminating near the posterior pair of marginal 8-shaped pores ; 5 setae 

 in the posterior row of multilocular pores and 2 in the penultimate row. 



Apex of abdomen: Notch present; lobes indicated; setae, apical 72 fi long, 

 interapical 9 m long, dorsal 7.2 fx long, inner ventral 3.6 fi long, intermediate 

 ventral 4 fi long, outer ventral 7.2 /j, long; anal ring with 6 setae 28 n long and 

 with an inner row of 6 and an outer one of apparently 12 pores ; tending toward 

 division on dorsal and ventral sides ; ventral surface of apex strongly sclerotized 

 in an irregularly rectangular area extending anteriorly from margin through 

 inner lobes, surrounding area slightly sclerotized and rugose. 



Data. — Described from unmounted material and four mounted 

 females on Machilus sp., Sozan, Taiwan (Formosa), R. Takahashi, 

 March 27, 1932, holotype and paratypes. 



This species is closely related to corallinum, but differs from it in 

 lacking large dorsal 8-shaped pores and claws, and in having usually 

 a larger number of spiracular quinquelocular and multilocular pores. 



Asterolecanium MASun Kuwana 



(Fig. 40, A-F; pi. 4, A) 



Described in 1916 (55, p. IJi-8), on leaves of bamboo from Tokyo 

 and Nagasaki, Japan. 



Habit. — Living on the lower surface of leaves. 



Test of female. — Nearly elongate elliptical, posterior end slightly narrowed ; 

 3 mm. long, 1.10 wide ; slightly convex dorsally, with a faint longitudinal median 

 carina having minute tubercles ; flat ventrally ; clear yellow, transparent, thin, 

 shiny, finely punctate ; marginal filaments whitish with a very faint yellowish 

 cast, slightly longer at anterior end than elsewhere ; elliptical larval exit in 

 margin. 



Adult female. — In shape similar to test, 2.75 mm. long, 1 wide. 



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

 from bases of apical setae, posterior pores about 12.6 fi long and 7 wide, the 

 others about 14.4 n long and 8 wide, usually less than a pore's width apart ; 

 quinquelocular pores in a single row terminating at the penultimate pair" of 

 8-shaped pores, slightly more numerous than 8-shaped pores ; disk pores nearly
