THE SCALE INSECT GENUS ASTEROLEC ANIUM 213 



Dorsal surface: A pair of submarginal 8-shaped pores near posterior end, 

 apparently 12 ix long and 6 wide; minute 8-shaped pores rather numerous: disk 

 pores very sparse; tubular ducts 24 ft long: dorsal tubes presumably present, 

 but not observed owing to poor condition of specimen. 



Ventral surface: Antenna circular, short, with '2 seta" Longer than diameter 

 of antenna; beak without setae; spiracle with bar rather broad, atrium slightly 

 enlarged and containing 6-9 cpiinquelocular pores, apparently 4 or 5 similar pores 

 extending from spiracle to body margin in a single row; multilocular pores, with 

 9 or 10 loculi. apparently in 3 rows, G pores in posterior row. 6 in median, 4 in 

 anterior: 2 dark-rimmed 8-shaped pores each side of beak, and a few on abdomen 

 apparently arranged in 2 transverse rows ; submarginal 8-shaped pores not ob- 

 served owing to poor condition of specimen: only 1 pair of submarginal setae 

 observed (others probably present but indeterminable), this pair near the 

 posterior pair of marginal 8-shaped pores ; 1 pair of setae each in the posterior 

 and median rows of multilocular pores. 



Apex of abdomen : Notch present ; lobes indicated : setae, apical 48 p. long, 

 interapical 5.4 /j. long, outer ventral 5.4 \x long ; anal ring with 4 setae 5.4 y. long 

 and two 9 n long, tending toward division on dorsal side ; ventral surface of apex 

 faintly sclerotized in dentate rows close to median line. 



Lawn. — Somewhat elliptical. 



Margin : With 28 8-shaped pores, the anterior 2 pairs longer than others, axes 

 of all longitudinal ; apparently 2 pairs of setae at anterior end. 



Dorsal surface: 8-shaped pores in a submedian row of apparently 9, on each 

 half of body, posterior pore apparently the smallest, anterior pore the largest, 

 all one-fourth to one-third smaller than marginal pores : disk pores not observed. 



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

 stout. 1 slender; antennal bases apparently one-fifth length of antenna apart: 

 beak setae, 2 pairs apical, 1 pair median ; spiracle with 1 trilocular pore ; leg setae, 

 coxa 4, femur 1 on inner margin near base and 1 each on inner and outer margins 

 near center, tarsus 2 on inner and 1 on outer margin : tibia one-half as long as 

 tarsus : apparently 9 pairs of submarginal 8-shaped pores ; probably 5 or 6 pairs 

 of submarginal minute setae, on abdomen and thorax, apparently 1 pair of sub- 

 marginal larger setae at anterior end ; 1 pair of setae between antennae and 

 mouth parts. 



Apex of abdomen : Notch present ; setae, apical 28 ,u long, interapical 3.6 /j. long, 

 outer ventral around 2 fi long; anal -ring with 6 setae 3.6 n hmg. 



Data. — Redescribed from two tests, one badly wrinkled mounted 

 female, and two poor mounted larvae from Arum linaria sp., Avisa- 

 Tvella, Ceylon, E. E. Green, October 1909. 

 _ The available specimens are very poor. Consequently it was impos- 

 sible to observe the dorsal tubes^ the ventral submarginal 8-shaped 

 pores, and the submarginal setae in the adult. In the female examined 

 marginal quinquelocular pores were also indeterminable, though they 

 were mentioned and figured by Green. The anal extremity in this 

 specimen is not retracted within the margin as originally described.

(Fig. 75. A-F; fig. 76, A-K ; fig. 77. A.; pi. 6, G I 



Habit. — Living on the lower surface of leaves. 



Test of female. — Nearly circular, approximately 1.3-1.6 mm. in diameter ; prac- 

 tically flat dorsally, with a small longitudinal median carina ; flat ventrally ; pale 

 greenish yellow, transparent, very thin, punctate, dull or shiny: marginal and 

 dorsal filaments pale pinkish or pale golden, the latter present along median line 

 and sometimes at varying intervals in submarginal area ; triangular larval exit 

 in ventral surface at margin. 



Adult female. — Nearly circular. 1.2-1.4 mm. in diameter. 



Margin: 8-shaped pores in a single row terminating about twice a pore's length 

 from bases of apical setae. 10-11 /x Ions; and G wide, slightly mere than a pore's 

 length apart. 



Dorsal surface: 8-shaped pores in a median row of 2-8 and sometimes 2-6 in 

 lateral area on each half of body, 11-12 m long and ^ wide; minute 8-shai>od and 

 disk pores sparse; tubular ducts 24 m long.
