between spiracular pore bands ; snbmarginal 8-sbaped pores in a single row 

 terminating near posterior row of multilocular pores, about one-third as numerous 

 as corresponding marginal 8-shaped pores : snbmarginal setae observed only be- 

 hind posterior spiracular pore bands, the posterior pair about halfway between 

 the last pair of marginal 8-shaped pores and apical setae; 2 pairs of setae in 

 posterior row of multilocular pores, 1 pair in each of the other rows, 1 pair 

 anterior to multilocular pores, and 1 pair still farther anteriorly. 



Apex of abdomen : Lobes barely indicated ; setae, apical (tips broken) 54 fj. long, 

 interapical 5.4 //, long, outer ventral 4-5 n long ; anal opening ventral, fairly close 

 to body margin, circular, its margin sclerotized. usually without setae, but some- 

 times with 1 minute seta ; a sclerotized area extending posteriorly from opening 

 nearly to body margin. 



Larva.— Elliptical. 



Margin : With 28 8-shaped pores, axes of all longitudinal ; 2 pairs of setae 

 anteriorly. 



Dorsal surface: 8-shaped pores, totaling 27-33 (usually 28 or 29), in a sub- 

 median row of 5-9 (usually 5-7) and a lateral row of 8 or 9, on each half of body, 

 uniform in size or a few anterior pores in each row slightly larger than the rest, 

 about one-half the size of marginal pores ; disk pores between submedian and 

 lateral 8-shaped pores. 



Ventral surface: Antennal setae, I, 1 ; IV, 1 ; V, 0: VI, 2 long, 2 stout, 2 fairly 

 stout, 2 slender ; antennal bases one-third length of antenna apart ; beak setae, 

 certainly 1 pair and possibly 2 pairs apical. 1 pair basal; anterior spiracle with 

 2 quinquelocular pores and posterior spiracle with 1 ; leg setae, coxa 3, femur 1 

 on inner margin near base, tarsus 1 each on inner and outer margins: tibia one- 

 fourth as long as tarsus ; 9 pairs of snbmarginal 8-shaped pores ; 7 pairs of sub- 

 marginal minute setae on abdomen, 1 pair of submarginal larger setae at anterior 

 end ; 3 pairs of setae near antennae. 



Apex of abdomen : Lobes faintly indicated ; setae, apical about 42 /j. long, inter- 

 apical about 5 fi long, outer ventral 3-4 jx long ; anal opening apical ; anal tube 

 very short, sclerotized, bulbous ; anal ring a sclerotized, circular band with 2 setae 

 around 5 /x long. 



Data. — Described from unmounted specimens, 8 mounted females, 

 and 14 mounted larvae from Quercus (Pasania) skanioma. Tuk Shan, 

 Kweichow, China, Y. Tsing, September 8, 1930, N. Y. B. G., holotype 

 and paratypes. 



This species can be separated from all known species on oak from 

 the Orient, except japonicum, by the presence of marginal quinque- 

 locular pores across the apex of the abdomen. It differs from japoni- 

 cum in having a sclerotized tongue-shaped projection on each of the 

 marginal 8-shaped pores, the arrangement of the marginal quinque- 

 locular pores in a single, uncrowded row, in having fewer than 20 

 quinquelocular pores in each spiracular row, and in having only 3 rows 

 of multilocular pores. 



Asterolecanium solenophoroides (Green) 



(Fig. 65, G-L; pi. 5, 0) 



Described by Green as Planchonia solenophoroides in 1896 (40, p. 6) ; 

 redescribed by him in 1909 (4#, p> S3Jl) and placed in Asterolecanium . 



Habit. — Living on the lower surface of leaves. 



Test of female. — Elongate, anterior two-thirds swollen, posterior third strongly 

 narrowed, apex sometimes slightly upturned ; 0.75-1.25 mm. long, 0.4-0.5 wide ; 

 strongly convex dorsally, often with a faint longitudinal median carina : flnt 

 ventrally; brownish yellow, semitransparent ; marginal filaments whitish, not 

 observed on posterior third; 0-4 dorsal filaments along median line, whitish, 

 longer than marginal ; elliptical larval exit in ventral surface at margin. 



Adult female. — In shape similar to test, 0.6-1.4 mm. long, 0.4 wide. 



Margin : 8-shaped pores in a single row terminating near posterior fourth 

 (more than twice length of am'cal seta from setal bases), riosterior pores ."-6 ,u 

 long and 3-4 wide, the others 7-8 /j. long and 4 wide, from the width to the length
