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

 submarginal setae in a complete row terminating near penultimate pair of mar- 

 ginal 8-shaped pores ; 3-5 setae in posterior row of multilocular pores and 2 

 setae in each of the next 2. 



Apex of abdomen: Lobes usually indicated; setae, apical (broken) apparently 

 80 fi long, interapical 5.4 ix long, inner ventral (nearly directly anterior to inter- 

 apical) 3.6-5.4 ix long, outer ventral 5.4-7.2 fx long; anal opening in ventral 

 surface and margin, elongate, fairly slender ; anal tube short, cylindrical, faintly 

 sclerotized throughout ; anal ring a sclerotized unclosed band at end of anal 

 tube, with 2 setae 2 ix long, the ring broken on ventral side for about a fifth of its 

 circumference. 



Second stage.- — Resembling adult female but smaller; margin with 2 or 3 quin- 

 quelocular pores near each spiracular pore band ; ventral surface with 3-5 

 quinquelocular pores between each spiracle and body margin, dark-rimmed 

 8-shaped pores very sparse, 2 pairs of setae observed in median abdominal area ; 

 apex of abdomen much as in adult, apical setae broken, others slightly shorter 

 than in adult, anal opening in ventral surface, not extending to margin, anal tube 

 very short, anal ring as in adult. 



Larva. — Elongate ovoid. 



Margin : With 28 8-shaped pores, the anterior 2 pairs slightly larger than the 

 others, axes of all longitudinal: 3 pairs of setae at anterior end. 



Dorsal surface : One to 3 submedian 8-shaped pores on each half of body, 

 situated on head and thorax, practically the same size as marginal pores of ; nine 

 segments : minute 8-shaped pores in a lateral row of apparently 10-13 on each 

 half of body : disk pores in submarginal and submedian areas ; a pair of small 

 setae near anterior pair of large 8-shaped pores. 



Ventral surface : Antennal setae, I. 1 ; IV, 1 : V, 1 ; VI, 2 long, 2 stout, 3 fairly 

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

 2 pairs apical, 1 pair basal; anterior spiracle with 1 trilocular and 1 quinquelocu- 

 lar pore, posterior with none; leg setae, coxa 4, femur 1 on inner margin near 

 base and 1 on outer margin near center, tarsus 1 each on inner and outer mar- 

 gins ; tibia around one-third as long as tarsus ; 9 pairs of submarginal 8-shaped 

 pores : 10 pairs of submarginal minute setae, on abdomen, thorax, and head, 1 

 pair of submarginal larger setae at anterior end; 2 pairs of setae between anten- 

 nae and mouth parts. 



Apex of abdomen : Notch present ; setae, apical 54 /x long, interapical 5.4 /x 

 long, dorsal (present in only 1 of specimens examined) 2 /x long, inner ventral 

 3.6 ix long, outer ventral 3.6-5.4 /x long ; anal opening in ventral surface and 

 margin ; anal tube very short on ventral side, sclerotized throughout, slightly 

 smaller at opening and ring than in center ; anal ring sclerotized, with 2 setae 

 5.4-6.2 ix long. 



Data. — Described from unmounted specimens (paratypes) and the 

 following mounted material : Two females and 18 larvae, Maskell No. 

 44, Cockerell Collection, paratypes; 5 females and 1 second-stage speci- 

 men from Leptospenrmm sp., Motueka, New T Zealand, from G. Brittin. 

 received in 1937, holotype and paratypes. 



Although this species is quite distinct from the others treated in 

 this paper, it appears most closely related to victoriae. 



Asterolecanium vulgare, new species 



(Fig. 81, H-T ; pi. 8, K) 



Habit. — Living on the lower surface of leaves. 



Test of fema le.— Longer than wide, posterior end slightly produced; 1-1.5 mm. 

 long, 0.65-1 wide ; flat dorsally and ventrally ; pale brownish yellow, transparent, 

 fairly thin, slightly punctate: marginal and dorsal filaments very pale yellow, 

 the latter fairly numerous; circular larval exit in margin. 



Adult female. — Longer than wide, posterior end sometimes slightly produced ; 

 1-1.4 mm. long, 0.6-1 wide. 



Margin: 8-shaped pores in a single row terminating about one-half length of 

 an apical seta from setal bases, penultimate pore twice its own length to slightly 

 more than twice length of apical seta from posterior pore and a few pores just 

 anterior to penultimate pore, twice a pore's length apart, the rest normally a 

 pore's length apart, posterior pore 7-8 /x long and 5 wide, penultimate and a
