THE SCALE INSECT GENUS ASTER OLE CAXIUM 171 



Larva. — Elliptical. 



Margin: With 28 B-shaped pores, the anterior pores slightly larger than the 

 posterior ones, axes of at least the posterior 6 pairs transverse, axes of the 

 others either transverse, diagonal, or longitudinal : 2 pairs of setae at anterior 

 end. 



Dorsal surface: 8-shaped pores in a suhmedian row of 8 or 9 and a lateral 

 row of 10 or 11, on each half of body, the anterior pores of each row slightly larger 

 than the posterior ones, and all slightly smaller than marginal pores ; disk pores 

 between suhmedian and lateral and between lateral and marginal 8-shaped pores. 



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

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

 2 pairs apical. 1 pair basal; anterior spiracle with 1 quinquelocular pore, posterior 

 spiracle with 2; leg setae, coxa 3. femur 1 on inner margin near base and 1 on 

 outer margin near center, tarsus 1 each on inner and outer margins ; tibia one-third 

 as long as tarsus : 9 pairs of snbmarginal 8-shaped pores : apparently 10 pairs of 

 submarginal minute setae, on abdomen, thorax, and head : 1 pair of setae between 

 antennae and mouth parts. 



Apex of abdomen : Notch present ; setae, apical 54 u long. Lnterapical 10.8 fj. long, 

 intermediate ventral (fairly near median line) 2.5-3.6 m long, outer ventral 3.6 n 

 long: anal opening apical; anal tube sclerotized on outer half and membranous 

 on inner half : anal ring with 4 setae 5-8 fi long and apparently with 1 or 2 pores. 



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

 following mounted material collected by G. Compere in Coolgardie. 

 West Australia : Four females. 3 second-stage specimens', and 1 larva. 

 Compere Xo. 85. holotype and paratypes: 7 females and 65 larvae on 

 MeJaleu-c-a sp.. Compere Xo. 1005, paratypes. 



This species resembles ventruosum as closely as any other known 

 form. 



ASTEROLECAXIUM QUAESITUM, new species 



(Fig. 57, F-K ; fig. 58. A-E ; pi. 4. 7) 



Habit. — Living on bark. 



Test of female. — Broadly ovoid, posterior end slightly produced: 2.5-3 mm. 

 long and 2-2.5 wide : strongly convex dorsally. nearly flat or slightly convex 

 ventrally ; dull greenish yellow, translucent, smooth, shiny ; fragmentary margi- 

 nal filaments apparently pale yellow or whitish, dorsal filaments rubbed oil: 

 elliptical larval exit in margin. 



Adult female. — Nearly circular or slightly ovoid. 2 mm. in diameter. 



Margin: 8-shaped pores mostly in an irregularly double row but posterior 

 10-20 pores, and a few others, in a single row terminating slightly more than 

 length of an apical seta from bases of setae, posterior pores 9-10 u long and 6 

 wide, the others 12 a long and 8 wide, the pores one to three times (usually 

 slightly more than once) a pore's length apart, distance between the 2 rows 

 equal to at least a pore's length; quinquelocular pores in a single row from 

 near antenna to a point 5-20 pores from end of row of 8-shaped pores, usually 

 one and one-half times as numerous as corresponding 8-shaped pores of nearer 

 row: disk pores among quinquelocular pores and in a similar position close to 

 8-shaped pores at anterior end where quinquelocular pores are missing, termi- 

 nating near posterior quinquelocular pores, not quite so numerous as correspond- 

 ing 8-shaped pores of nearer row. 



Dorsal surface: 8-shaped pores numerous, 8-9 ^ long and 5 wide: minute 

 8-shaped pores not observed : disk pores fairly sparse; tubular ducts 30 ft long. 



Ventral surface: Antenna thimble-shaped, sunken in derm, with 4 setae nearly 

 as long as. and 2 longer than, diameter of antenna: 4 or 5 quinquelocular ; 

 sometimes present between antenna and margin: beak with 2 pairs of s< 

 spiracular bar broad, sometimes slightly expanded at inner end; derm around 

 opening or on 1 side of spiracle sunken and filled with quinquelocular por 

 total of 45-55 such pores in that group and in a double to quadruple row 

 extending to margin: multilocular pores in 7 complete rows and 1 interrupted 

 row, the posterior row with m-12 pores, penultimate row with 21-25, each of 

 next 2 with L'3-35. next with 1!>-24. next with 15. next with 9-10, and intern: 

 row with 1 or 2. or a total of 132-153 pores, having 5 15 (usually 10) loculi; 

 5-10 dark-rimmed 8-shaped pores each side of beak, some scattered anterior to
