THE SCALE INSECT GENUS ASTEROLECAXIUM 129 



Asterolecaxium miliaris variety miliaris (Boisduval) 



(Fig. 41, B~G; pi. 5, E) 



Described in 1869 (.9, pp. 201-202) as Ohermes nriliaris on Bam- 

 frusa distorta from the garden of Hamma, Alger, Algeria. 



Habit. — Living on stems, and both surfaces of leaves. 



Test of female. — Longer than wide but differing in proportions of length to 

 width, anterior end rounded, sides often parallel, posterior end slightly narrowed 

 5i nd produced; 1-1.6 mm. long, 0.4-0.9 wide; nearly flat to very slightly convex 

 dorsally. usually with a faint longitudinal median carina and sometimes with 

 very faint transverse striatums ; flat ventrally ; greenish, brownish, or clear 

 pale yellow, transparent, thin, shiny, slightly punctate ; marginal filaments 

 whitish to pale pinkish ; circular larval exit in ventral surface at margin. 

 Adult female. — In shape similar to test, 1-1.4 mm. long, 0.3-0.7 wide. 



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

 of apical seta from setal bases, around 8 li long and 4.5 wide, slightly more than 

 a pore's length apart near posterior end, usually around a pore's width apart 

 elsewhere; quinquelocular pores in a single row, starting on anterior margin 

 approximately halfway between median line and anterior spiracular pore bands, 

 and ending halfway between posterior spiracular pore bands and the posterior 

 ' pair of 8-shaped pores, at least as numerous as corresponding 8-shaped pores. 



Dorsal surface: Minute 8-shaped pores fairly numerous; disk pores rather 

 sparse; tubular ducts 24 ll long; dorsal tubes present. 



Ventral surface : Antenna circular, flat, with 2 setae slightly longer than 

 diameter of antenna ; beak without setae ; spiracular bar nearly linear ; 10-18 

 quinquelocular pores extending from spiracle to body margin in an irregularly 

 single row ; 2-4 dark-rimmed 8-shaped pores each side of beak, a few on anterior 

 end, and a few on abdomen tending toward arrangement in 6 transverse rows with 

 most of pores in lateral area; submarginal 8-shaped pores in a single row 

 terminating near the penultimate pair of marginal 8-shaped pores, about one- 

 third as numerous as marginal 8-shaped pores: 6 pairs of submarginal setae on 

 abdomen, the posterior pair near the penultimate or posterior pair of marginal 

 8-shaped pores: 1 pair of setae posterior to genital opening. 1 pair anterior to 

 opening, and 1 pair anterior to the latter. 



Apex of abdomen : Notch present ; lobes indicated : setae, apical 56-GO u. long, 

 interapical 9-12 n long, inner ventral 6-8 /* long, outer ventral 8-10 \x long ; anal 

 ring with 8 setae, each 32 fi long and with an inner row of 6 and an outer one 

 of 14 pores, divided on dorsal sid ,j . 



Second stage. — Resembling adult female but much smaller; margin without 

 quinquelocular pores: ventral surface with 4 or 5 quinquelocular pores in each 

 spiracular row, with 1 pair of setae in median abdominal area ; apex of abdomen 

 as in adult but all setae around one-fourth shorter. 



La rva . — Elliptical. 



Margin: 8-shaped pores normally 28 in number, but a few specimens with only 

 25 or 26, the posterior pair very slightly larger than the next 5 pairs, and about 

 same size as the 7 anterior to those, anterior pair slightly the largest, ax 

 all longitudinal ; 3 pairs of setae at anterior end. 



Dorsal surface: 8-shaped pores in a submedian row of 4-8 on each half of 

 body, with a total of 11-16, anterior pore slightly the largest, all about two-thirds 

 size of marginal pores of same segments; disk pores in lateral area and a few 

 in submarginal area. 



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

 stout. 1 slender; antennal bases one-fourth length of antenna apart: beak setae, 

 2 pairs apical, 1 pair median; anterior spiracle with 1 trilocular, posterior 

 spiracle with 1 trilocular and 1 quinquelocular pore: leg setae, coxa 4. lemur 

 1 on inner margin near base and 1 on inner and outer margins near center, 

 tarsus 2 on inner and 1 on outer margin; tibia two-thirds length of tarsus; 

 9 pairs of submarginal 8-shaped pores; t; pairs of submarginal minute setae on 

 abdomen, 2 pairs of submarginal larger setae at anterior end: 1 pair of setae 

 between antennae and mouth parts. 



Apex of abdomen: Notch present; lobes indicated: setae, apical 27-29 it long, 

 interapical 7.2 fx long, inner ventral 5.4 ^ long, outer ventral 3.0-5.4 p long; 

 anal ring with 6 setae 12.0 m long and with an inner row of 6 and an outer row 

 of 10 or 12 pores, divided on dorsal and ventral sides.
