THE SCALE INSECT GENUS ASTEROLECANIUM 155 



Test of female.— Somewhat elongate, 1.5-1.95 mm. long and 0.75 

 widest at anterior third, tapering from there to anterior end and to constriction 

 near posterior end, wider and rounded at posterior end. appearing slipper-sl 

 on ventral surface; convex dorsally, sloping strongly to margin, somewna 

 stricted at posterior sixth with posterior end enlarged and sloping to margin; 

 ventrally concave at posterior end. flat elsewhere; pale greenish yellow or fairly 

 clear pale yellow, transparent, thin, smooth, shiny; marginal filaments whitish; 

 larval exit a semicircular slit in ventral surface at marg 



Adult female. — Constricted near posterior end and slipper-shaped, or not con- 

 stricted and elongate elliptical; 1.4-1.75 mm. Long, 0.65-O.85 wide. 



Margin : 8->haped pores in a single row terminating around three times the 

 length of an apical seta from setal bases, u long and 8 wide, usually a pore's 

 width apart but sometimes spaced at intervals equal to the length of a pore, 

 and the posterior 2 or 3 pores occasionally three times a pore's length apart; 

 Quinquelocular pores in a single row of 8-16 at points where each spiracular 

 pore band meets body margin, the rows not meeting between the spiracular pore 

 bands, the spacing of these pores the same as for the corresponding 8-shaped 

 pores. 



Dorsal surface : A total of 20-25 8-shaped, somewhat tubular pores in sub- 

 marginal area. 1 or 2 sometimes in median area anterior to mouth parts. 5-6 n 

 long and 4-."i wide, the tube wider than a tubular duct and slightly more than 

 one-half as long, very slightly wider at outer end than at inner end : minute 

 8-shaped pores numerous; disk pores fairly numerous; tubular ducts in scattered 

 groups, 28 . long. 



Ventral surface: Antenna very short, with 2 setae as long as. or slightly longer 

 than, diameter of antenna : beak with 3 pairs of setae : spiracular bar expanded 

 at inner end : approximately 12 quinquelocular pores extending from spiracle to 

 body margin in an irregularly single and double row, the 2 or 4 pores nearest 

 op< ning situated in a furrow which flattens out near body margin ; 2 dark- 

 rimmed 8-shaped pores each side of beak, 1 anterior to mouth parts, and a 

 few tending toward arrangement in 3 or 4 transverse rows on abdomen; sub- 

 marginal 8-shaped pores in a single row apparently terminating at the fifth from 

 the posterior pair of marginal 8-shaped pores, about one-third as numeroi - 

 corresponding marginal 8-shaped pores: submarginal setae in a complete row 

 terminating about length of an apical seta from bases of apical setae; 10. 12. or 

 14 setae \ osterior to genital opening, arranged in 4 transverse rows of 3 each 

 when 12 are present, occasionally 2 setae between anterior row and genital 

 opening. 



Apex of abdomen: Setae, ap"cal 76 /j. long, interapical 10 p. long, outer ventral 

 5 m long; anal opening ventral, circular, its margin sometimes faintly 

 sclerotized. 



Larva. — Elongate elliptical. 



Margin: With 28 8-shaped pores, ax^s of all longitudinal: a pair of minute 

 setae close to each of the posterior 3 pairs: 1 pair of setae at anterior end. 



Dorsal surface: 8-shaped pores in a submedian row of 5 or 6 on each half of 

 body, about one-half the size of marginal pores; 2-4 disk pores between lateral 

 and marginal 8-shaped pores. 



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

 stout: antennal bases marly one-half length of antenna apart: beak setae, 3 

 pairs apical. 1 pair basal; each spiracle w : th 2 trilocular pores or posterior 

 spiracle with 1 trilocular and 1 cpiinquelocular pore: leg setae, coxa 3, 

 femur 1 on inner margin near base, tarsus 1 each on inner and outer margins; 

 tibia one-half as long as tarsus; pairs of submarginal 8-shaped pores; appar- 

 ently 10 pairs of submarginal setae, on abdomen, thorax, and head: 5 setae near 

 antennae. 



Apex of abdomen: Setae, apical 4S-") a long, interapical 7.2 u long, a pair 1 u 

 long entad of interapical, outer ventral 3.6 ,u long; anal opening ventral, circular, 

 its margin sometimes slightly sclerotized; anal tube very short; anal ring poorly 

 differentiated.
