THE SCALE INSECT GENUS ASTEROLECANIUM 183 



Dorsal surface : 8-shaped pores in a lateral row on each side of body and in a 

 median row, the lateral row usually single but. sometimes double for 1 or 2 pores, 

 the median row usually single for posterior 2 or 3 pores, but double anterior to 

 those, and sometimes triple or even quadruple, a total of 23-46 observed (the ma- 

 jority of specimens examined with 28-38), individual pores 16-18 n long and 9.5- 

 10.6 wide: minute 8-shaped and disk pores fairly numerous: tubular duets 36 u 

 long ; dorsal tubes present. 



Ventral surface: Antenna circular, short, with 2 setae longer and 1 or 2 

 shorter than diameter of antenna ; beak without setae ; spiracle with bar fairly 

 broad: 9-16 quinquelocular pores extending from spiracle to body margin in an 

 irregularly single or double row, the 3-7 pores nearest spiracle usually in a 

 fairly definite group: multilocular pores, with 10 loculi, in 5 complete and 3 

 interrupted rows, the posterior row with 10-18 pores, penultimate row with 

 14-21, next with 15-25, next with 10-19, next with 6-9, and each of interrupted 

 rows with 2-6, the total number 6S-97 ; 1 dark-rimmed 8-shaped pore each side 

 of beak, a few scattered anterior to mouth parts, a few in 2 rather irregular, 

 indefinite longitudinal rows in lateral area of abdomen, and others in 3 transverse 

 rows on abdomen ; submarginal 8-shaped pores in a single row terminating near 

 genital opening, at least half as numerous as marginal 8-shaped pores : 3-5 

 disk pores on each half of body in a submarginal row extending from near 

 posterior row of multilocular pores to near apical setae and 2 or 3 usually in 

 submarginal area near anterior end of body: 6 pairs of submarginal setae on 

 abdomen, the posterior pair fairly near the penultimate pair of marginal 8-shaped 

 pores; 1 pair of setae in each of the posterior 4 rows of multilocular pores. 



Apex of abdomen : Slightly concave ; setae, apical 27.6-30 p. long, interapical 

 9-12.6 long, outer ventral 7.2-9 /i long ; anal ring with 6 setae 27-30.7 fi long 

 and with an inner row of 6 and an outer row of 14 or 16 pores, divided, or tending 

 toward division, on dorsal side ; ventral surface of apex slightly sclerotized in 

 median area near margin. 



Second stage. — Nearly elongate elliptical, posterior end narrowed : margin with 

 quinquelocular pores much less numerous than in adult : dorsal surface with 

 5 8-shaped pores in median and submedian areas ; ventral surface with 3 or 4 

 quinquelocular pores in each spiracular row, no setae in median region: apex 

 of abdomen as in adult but all setae about one-half shorter and number of pores 

 in anal ring indeterminable. 



Larva. — Elongate elliptical. 



Margin : With 28 8-shaped pores, the anterior pair distinctly the largest, the 

 next pair and the posterior and penultimate pairs about equal in size and 

 slightly larger than the remainder, axes of the posterior 6 pairs transverse, of 

 the others longitudinal : 3 pairs of setae at anterior end. 



Dorsal surface: 8-shaped pores in a submedian row of 10 or 11 and a lateral 

 row of 7 or 8, on each half of body, a total of 35 observed, 1 or 2 pores of each 

 row slightly larger than the rest, all at least slightly smaller than marginal 

 pores of same segments: disk pores between lateral and marginal, and a few 

 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. 1 slender: distance between antenna] bases around one-third length of 

 antenna: beak setae, 2 pairs apical, 1 pair median: spiracle with 1 triloculai 

 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: 9 pairs of submarginal 8-shaped pores; <; pairs of 

 submarginal minute setae on abdomen. 3 pairs of submarginal larger setae at 

 anterior end: 1 pair of setae between antennae and month parts. 



Apex of abdomen: Setae, apical 4.1 ,a long, interapical 14.4-16.2 p long, outer 

 ventral 3.6 , a long: anal ring with 6 setae, each 5.4 u long, apparently not divided. 



Test of male. — Elongate elliptical. 1.10-1.4 mm. long. 0.5 wide: dorsally convex 

 at anterior end. sloping to posterior end ; flat ventrally : pale yellow, transparent, 

 very thin, slightly punctate: marginal filaments whitish, slightly longer on 

 anterior than on posterior half: dorsal filaments whitish, fragmentary, appar- 

 ently arranged in a submarginal and a median row. 



Adult male. — 1 mm. long. 



Head: Antenna 10-segmented, formula (longest to shortest), (III). (IV, V. 

 VI). i VII. X), (IXi. (VIU). (I. Hi: antenna! setae. 1. 11: 11. 14: 111. 12: 

 IV. 17; V. 2d: VI. VII. 24: VIII, 20: IX. 21: X. 1-; fairly long and 4 very long: 

 basal bars diagonal: 2!) setae between ventral eye-pot- and antennae; 2 - 

 dorsally near antennae.
