THE SCALE IXSECT GENUS ASTEROLECAXIUM 53 



Data. — Described from one test, one mounted female, and four 

 mounted larvae on Palmae (Uatostigma radiataf), Cordoba, State of 



Cauca, Colombia. C. B. Doyle. December 1905. U. S. X. H.. paratypes ; 

 unmounted specimens, two* mounted females, and two mounted larvae 

 on Palmae. San Carlos, Bolivia. O. Buchtier. November 9, 1907. 1 1". S 

 N. H.. holotype and paratypes. 



Most closely related to palmae. from which it differs in several char- 

 acters, the most conspicuous being the number and arrangement of the 

 dorsal 8-shaped pores, the presence of 22 multilocular pores instead of 

 43 to 51. and the shorter anal ring setae, which are only about one-half 

 as long as the apical setae. 



Asterolecaxium borboxiae Brain 



(Fig. 9. A-H) 



Described in 1920 {12, p. 111). 



Habit.— "On leaves" (12, p. 111). 



Test of femile. — "Test of adult 9 small, about 1 mm. long and 0.75 mm. 

 broad, rounded in front and rather pointed behind, slightly convex with the 

 margin rather thickened and slightly crenulate. The extreme posterior extremity 

 appears tubular and is upturned or recurved over the back. There is apparently 

 no marginal or dorsal fringe. The colour is pale greenish yellow and the test is 

 almost transparent, showing the dark bcdv of the female at the anterior end."' 

 (12, p. 111.) 



Adult female. — Somewhat ovoid, posterior end narrowed and slightly pro- 

 duced ; 0.9-1.10 mm. long. 0.6-0.7 wide. 



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

 from bases of apical setae, 12 m long and 7-S wide, two to six limes a pore's 

 length apart. 



Dorsal surface : 8-shaped pores scattered over anterior two-thirds of body, not 

 numerous, 8-9 y. long and 5 wide ; minute 8-shaped pores not observed ; disk pores 

 fairly numerous: tubular ducts 32 i± long. 



Ventral surface : Antenna faintly sclerotized. circular, often sunken in derm, 

 with 3 setae longer than diameter of antenna: beak with 2 pairs of setae: 

 spiracular bar fairly broad: 20-35 quinquelocular pores extending from spiracle 

 to body margin in a double to quadruple' row : multilocular pores totaling 7-10 

 and having 5-10 loculi. in 3 rows, posterior row with 2. median with 2 or 3. 

 anterior with 4 or 5 : 3 or 4 dark-rimmed 8-shaped pores in a loose group each 

 side of beak. 1 or 2 anterior to mouth parts, and a few posterior to beak : sub- 

 marginal S-shaped pores in a single row terminating near anterior row of multi- 

 locular pores, usually as numerous as marginal 8-shaped pores: apparently 

 pairs of submarginal setae posterior to posterior spiracles, the posterior pair 

 near the posterior pair of marginal 8-shaped pores: 1 pair of setae in posterior 

 row of multilocular pores. 2 pairs each in median and anterior rows. 2 pairs 

 anterior to those, and 1 pair still further anteriorly. 



Apex of abdomen: Setae, apical 44-Ou p long, interapica! 5.4 n long, outer 

 ventral about G.4 a long: anal opening in margin, circular: anal tube nearly 

 cylindrical, sclerotized near opening and near ring, membranous in middle: anal 

 ring a sclerotized band. 



Larva. — Elongate ovoid. 



Margin: Without 8-shaped pores; 2 pairs of setae at anterior end. 



Dorsal surface: 8-shaped pores, totaling 82 or 34. in a submedian row of 4 or 

 5 and a lateral row of 12. on each half of body, anterior lateral pores very 

 slightly larger than posterior pores, submedian pores practically equal in size to 

 posterior lateral pores: disk pores between submedian and lateral 8-shaped pores. 



Ventral surface: Antenna! setae. I. 1: IV. 1: V. 0: VI. 2 long, 2 stout, 3 fairly 

 stout: antenna! bases one-fourth length of antenna apart: beak setae, 2 pairs 

 apical, 1 pair basal; spiracle with 1 trilocular and 1 quinquelocular pore or with 

 2 trilocular pores; 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 around one-third as long as tarsus; 7 pairs of submarginal 8-shaped pores. 

 none between antennae: apparently 5 pairs of minute submarginal setae on 

 abdomen ; 1 pair of setae between antennae and mouth pans.
