multilocular pores, with 10 loculi, in 4 complete and 3 interrupted rows, 6 in each 

 of the posterior 3 rows, 4 in the anterior complete row, and 2 in each of the 

 interrupted rows, making a total of 28 ; 3 or 4 dark-rimmed 8-shaped pores each 

 side of mouth parts and a few arranged in 2 transverse rows posterior to beak ; 

 submarginal 8-shaped pores in a single row terminating near anterior complete 

 row of multilocular pores, usually about as numerous as the marginal 8-shaped 

 pores ; 7 pairs of submarginal setae posterior to posterior spiracles, the posterior 

 pair slightly nearer to the posterior pair of marginal 8-shaped pores than to bases 

 of apical setae ; 2 pairs of setae in posterior row of multilocular pores, and 1 pair 

 in each of the other complete rows and in posterior interrupted row. 



Apex of abdomen : Lobes barely indicated ; setae, apical 54 /x long, interapical 

 (on ventral surface close to margin) 3.6 fx long, outer ventral 3 /x long; anal 

 opening ventral, its own diameter from body margin, circular, its margin sclero- 

 tized, with 2 setae, each apparently 2 fx long, on anterior edge. 



Data. — Described from one unmounted specimen, paratype, and one 

 mounted female, holotype, on Querent hemisphaerica, Indo-China, 

 August 1922, N. Y. B. G. 



Resembling several oak-inhabiting species from the Orient, but dif- 

 fering from each of those in being elongate rather than circular, and in 

 having somewhat scattered dorsal 8-shaped pores. 



Asterolecanium agavis, new species 



(Fig. 4, A-K; pi. 1, C) 



Habit. — Living on both surfaces of leaves, usually in shallow depressions. 



Test of female. — Nearly circular, posterior end slightly produced ; 1.5-2 mm. in 

 diameter ; convex dorsally, sometimes with faint transverse striations, flat ven- 

 trally ; bright yellow, transparent, fairly thin, slightly punctate ; marginal and 

 slightly shorter dorsal filaments white, the latter present in median area, entad 

 of submarginal area, and sometimes over most of surface ; elliptical larval exit 

 in margin. 



Adult female. — Shape similar to that of test, 1.25-1.75 mm. in diameter. 



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

 apical seta from setal bases, posterior pores 12 fx long and 8 wide, others 12-14 /x 

 long and 8-9 wide, usually spaced around a pore's width apart ; quinquelocular 

 (often actually trilocular or multilocular) pores in a single row starting about 

 10 8-shaped pores anterior to anterior spiracular pore bands and ending about 

 15 8-shaped pores posterior to posterior spiracular pore bands, sometimes inter- 

 rupted for 1-8 8-shaped pores between anterior and posterior spiracular pore 

 bands, usually as numerous as corresponding 8-shaped pores ; disk pores dorsad 

 of 8-shaped pores, irregularly spaced and less numerous than those and terminat- 

 ing near the posterior pair of 8-shaped pores. 



Dorsal surface : 8-shaped pores in median area and few to many entad of 

 submarginal area, sometimes arranged in transverse groups entad of submarginal 

 area, reaching median group only near mouth parts, rarely scattered between 

 median group and margin, 12-14 jx long and 8-9 wide ; minute 8-shaped and disk 

 pores numerous ; tubular ducts 30 /x long. 



Ventral surface : Antenna short, sunken in derm, with 3 setae about equal to, 

 and 1 slightly longer than, diameter of antenna ; beak with 2 pairs of setae ; 

 spiracular bar slightly expanded at inner end; 20-40 (usually 30^40) quinque- 

 locular pores extending from spiracle to body margin in a double to quadruple 

 row ; multilocular pores, with 10 or 11 loculi, in 5 complete and 3 or 4 interrupted 

 rows, each of the posterior 4 rows with 13-22, anterior complete with 11 or 12, 

 and each of the interrupted rows with 2-9, making a total of 89^105 ; 1-A dark- 

 rimmed 8-shaped pores each side of mouth parts, others scattered anteriorly, 

 some in a rather indefinite lateral row, and in 2 or 3 indefinite transverse rows 

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

 row of multilocular pores, in proportion of 1 to 3 or 4 marginal 8-shaped pores ; 

 submarginal setae in a complete row terminating near the posterior pair of 

 marginal 8-shaped pores ; 4 or 5 setae in posterior row, and 2 or 3 in each of 

 next 2 rows of multilocular pores. 



Apex of abdomen : Notch present ; lobes indicated ; setae, apical 72-82 jx long, 

 interapical broken, at least 14.4 /x long, dorsal 9-14.4 fx long, intermediate ventral
