the marginal row of 8-shaped pores ; 1 pair of setae posterior to genital opening, 

 1 pair anterior to opening, and 1 pair anterior to those. 



Apex of abdomen : Setae, apical 4 fi long, interapical 1.8 fi long, both on ventral 

 surface close to margin, outer ventral 2 ^ long, anterior to and outside apical ; 

 anal opening ventral, close to margin, narrow horseshoe-shaped ; anal tube 

 sclerotized at opening, membranous in center, and sclerotized at inner end, where 

 it is larger than at outer end ; anal ring sclerotized, thickened. 



Data. — Described from two unmounted and two mounted females 

 on Bambusa sp., near Tung Heung, Kwong Ning district, Kwang- 

 tung, China, F. A. McClure, April 25, 1925, holotype and paratopes. 



This species resembles ceriferwm in some of the structures of the 

 apex of the abdomen, but differs from it in practically all other 

 characters. 



ASTEROLECANIUM EPACRIDIS (Maskell) 



(Fig. 21, C-N ; pi. 8, I) 



Described in 1882 (68, pp. 224-226) as Planchonia epacridis on 

 Leucopogon frazeri from Amberley, New Zealand. 



Habit. — Living on the upper surface of leaves, in shallow pits. 



Test of female. — Rather elongate ovoid, posterior end sometimes slightly pro- 

 duced; 1.3-1.6 mm. long, 0.85-1 wide; strongly convex dorsally, most strongly 

 so at anterior third, sloping to margins, nearly flat at posterior end, with or 

 without a faint longitudinal median carina near posterior end ; flat or slightly 

 convex ventrally ; greenish yellow, transparent, thin, shiny, slightly punctate in 

 submarginal area ; marginal filaments whitish and dorsal filaments broken off ; 

 elliptical larval exit in ventral surface. 



Adult female. — Slightly longer than wide, 1-1.4 mm. long, 0.9-1 wide. 



Margin : 8-shaped pores in a single row terminating around twice the length 

 of posterior pore from bases of apical setae, posterior pores 10 m long and 7 wide, 

 the others 12 fi long and 8 wide, usually about a pore's width apart; quinque- 

 locular pores in a single row terminating near the fourth to the eighth pore from 

 the posterior end of the row of 8-shaped pores and at least as numerous as 

 the 8-shaped pores ; disk pores ventrad of quinquelocular pores, terminating near 

 the posterior pair of 8-shaped pores, much less numerous than the latter. 



Dorsal surface: 8-shaped pores in a median group of 5-9, and none, or 3-11, 

 in a submarginal row, median pores apparently arranged in a loose group near 

 center, submarginal pores placed at irregular intervals, and measuring 12 /x long 

 and 8 wide ; minute 8-shaped and disk pores numerous ; tubular ducts about 32 n 

 long. 



Ventral surface : Antenna very short, with 3 setae as long as, or slightly 

 shorter than, diameter of antenna ; beak with 2 pairs of setae ; spiracle with 

 bar expanded at inner end, atrium somewhat enlarged but shallow, 2-7 quin- 

 quelocular pores in atrium and on edge of opening, and 2-10 extending from 

 spiracle to body margin in an irregularly single row, 7-17 pores in atrium and 

 row combined ; multilocular pores, totaling 49-68 and having 7-11 loculi, in 5 

 complete and 3 or 4 poorly defined interrupted rows, posterior row with 4 or 5, 

 penultimate with 9-13, next with 8-15, next with 7-13, next with 5-8, each 

 of next 3 with 2-7 and occasionally a single pore representing another row 

 anterior to posterior spiracles ; 2-4 dark-rimmed 8-shaped pores each side of 

 beak, a few on anterior end, and a few arranged in 5 or 6 transverse rows on 

 abdomen ; submarginal 8-shaped pores in a single row terminating near penulti- 

 mate row of multilocular pores, usually as numerous as marginal 8-shaped pores ; 

 submarginal setae in a complete row terminating anterior to the posterior pair 

 of marginal 8-shaped pores; 2 pairs of setae in posterior row of multilocular 

 pores and 1 pair in each of the next 3 rows. 



Apex of abdomen : Notch present ; lobes indicated ; setae, apical 76 m long, 

 interapical 7.2-9 /x long, dorsal 3 /x long, inner ventral 5.4-7 /x long, outer 

 ventral 7.2-9 ,u long ; anal ring with 6 setae 32-38 /x long, also with an inner 

 row of apparently 6 and an outer one of at least 14 pores, divided on dorsal 

 side and tending toward division on ventral ; ventral surface of apex sclerotized 

 in a roughly linear area anterior to interapical setae, area between linear bars 

 sclerotized in dentate rows.
