few pores anterior to it 8 n long and 6 wide, the others 10 n long and 6 wide ; 

 disk pores dorsad of, and about as numerous as, 8-shaped pores, terminating 

 near posterior pair of 8-shaped pores. 



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

 usually absent from a narrow submedian area posterior to mouth parts, arranged 

 roughly in transverse rows of about 6-10 each, 12 y, long and 7-8 wide; minute 

 8 shaped pores fairly numerous in median area, sparse elsewhere: disk pores 

 near majority of 8-shaped pores, 1 or 2 to an 8-shaped pore, a few elsewhere; 

 tubular duets 32 \± long; dorsal tubes present. 



Ventral surface: Antenna circular, slightly raised, with 2 setae much longer 

 than diameter of antenna: beak without setae: spiracular bar expanded at inner 

 end; 3-7 quinquelocular pores in a loose group near spiracular opening, the 

 pores in excess of 4 in direction of body margin, but not reaching it ; multilocular 

 pores, with 10 loeuli, in 4 complete and 2 interrupted rows, posterior 

 row with 7-10 pores, penultimate with 8 or 0. next with 9-12. next with 5 or 6, 

 and each of interrupted rows with 1-4. the total number being 34-41; 1-3 dark- 

 rimmed 8-shaped pores each side of beak, a few anterior to mouth parts, a few 

 in lateral area of abdomen, and in 2 or 3 transverse rows among multilocular 

 pores: submarginal 8-shaped pores in a single row terminating near penultimate 

 row of multilocular pores, less numerous than corresponding marginal 8-shaped 

 pores: 6 pairs of submarginal setae on abdomen, the posterior pair around 

 one-half length of an apical seta from bases of apical setae : 1 pair of setae in 

 each of the posterior 3 rows of multilocular pores. 



Apex of abdomen: Notch present: lobes indicated: setae, apical 76 /i long, 

 interapical 9 fi long, inner ventral 5.4 /x long, outer ventral 7.2 y. long; anal ring 

 with 4 setae 32 \x long and two 36 n long and with an inner row of 6 and an 

 outer one of apparently 14 pores, tending toward division on dorsal side; ventral 

 surface of apex weakly sclerotized in dentate rows. 



Test of male. — Nearly elliptical, posterior end slightly pointed; 1.4 mm. long, 

 0.75 wide; slightly raised dorsally, without or with a very faint longitudinal 

 median carina: flat ventrally : pale yellow, transparent, very thin: marginal fila- 

 ments very pale yellow to whitish, longest at anterior end. 



Adult male. — 1.3 mm. long. 



Head: Antenna 10-segmented. formula (longest to shortest). (IV), (V), (III. 

 X), (VI). (VII. VIII. IN), (I, II); antennal setae. I, 11: II. 17; III-X. 21-24; 

 X also with 1 stout and 4 very long; basal bars diagonal: 21 setae near ventral 

 eyespots. 



Thorax: Bar between wing bases curved on anterior margin, nearly three times 

 as long as wide: tibia nearly as long as tarsus. 



Abdomen: Five segments each with a seta dorsally on lateral margin, 3 seg- 

 ments each with a seta in submedian ventral area : each lobe area with 1 long 

 and usually 2 short setae: penis sheath with 2 pairs of setae dorsally near base 

 and 6 or 7 setae on each side of ventral opening. 



Data. — Described from unmounted material, six mounted females, 

 and two mounted adult males from Barmbusa sp., Lung T'au Shan. 

 K'uk Kono; district, Kwangtuno-. China. F. A. McClure. January 7. 

 1925, holotype and paratypes. 



This species closely resembles china t \ but it lacks marginal quinque- 

 locular pores and the spiracular quinquelocular pores are arranged 

 differently than in chinae. 



Asterolecanium zanthenes, new species 



(Fig. 82, A.-M; fig. 83, -t ; fig. si. A.-Q ; pi. 2, C) 



Treated by Leonardi in 1920 (37, pp. 2U-846) as A. them (Doug 

 las). 



Habit. — Living on twigs, stems, and leaf petioles and occurring on flat surface - 

 or in shallow pits. 



Test of female. — Longer than wide, sometimes slightly pyriform, posterior end 

 elevated and often turned forward: 2-2.5 mm. long, 1.5-2.15 wide: convex dor- 

 sally, flat ventrally: brownish or pale dear yellow, translucent, rather thick, 

 slightly punctate; marginal filaments whitish: dorsal filaments in a tuft along
