THE SCALE INSECT GENUS ASTEROLECANIUM HI 



Asterolecanium ingae, new species 



(Fig. 32, C-H; pi. 3, F) 



Listed by Wolcott in 1936 (100, p. 122), as Asterolecanium sp. now 



Habit. — Living on bark. 



Test of female. — Broad ovoid, posterior end strongly narrowed, produced, and 

 sometimes slightly elevated; 1.25-1.5 mm. long, 1-1.25 wide; slightly convex 

 dorsally, without or with a faint, broad, longitudinal median carina ; flat ven- 

 trally; greenish, pale yellow, or nearly colorless, transparent, thin, slightly 

 punctate; marginal and dorsal filaments pale to deep pinkish, sometimes nearly 

 rust, the latter dense along median line and in lateral and submarginal areas, 

 less numerous in submedian area, ranging from at least as long to twice as long 

 as marginal filaments; circular larval exit in margin. 



Adult female. — Similar to test in shape, 1-1.25 mm. long, 0.9-1.10 wide. 



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

 length of an apical seta from setal bases, posterior pores 9-10 ix long and 6-8 

 wide, the others 12 fi long and 8 wide, usually slightly more than a pore's width 

 apart at posterior end, and from a pore's w T idth to a pore's length apart else- 

 where ; quinquelocular pores in a single row, usually absent between antennae 

 and usually terminating at about the eighth (sometimes as much as the seven- 

 teenth) posteriormost pair of 8-shaped pores, at least as numerous as 8-shaped 

 pores near posterior end, elsewhere usually one and a half times and occasion- 

 ally twice as numerous as corresponding 8-shaped pores ; disk pores ventrad of 

 quinquelocular pores and as near to submarginal as to marginal 8-shaped pores, 

 terminating around length of an apical seta from setal bases, nearly or actually 

 as numerous as marginal 8-shaped pores. 



Dorsal surface: 8-shaped pores along median line and scattered elsewhere 

 though sparse, and sometimes absent in a narrow submedian area on posterior 

 half, some pores 9-10 n long and 6-7 wide, the majority 12 fi long and 8 wide, and 

 some 18-20 fi long and 13 wide, the largest pores along median line in a fairly 

 regular single row, and smaller pores in an irregularly single or double row on 

 each side, largest pores also occurring in 3 fairly definite rows paralleling body 

 margin and at fairly uniform intervals from it, with surrounding area covered 

 with smaller pores ; minute 8-shaped pores numerous ; disk pores fairly sparse ; 

 tubular ducts 40 n long. 



Ventral surface : Antenna dome-shaped, sunken in derm, with 2 setae longer 

 and 1 or 2 shorter than diameter of antenna ; beak with 2 pairs of setae ; spiracle 

 with bar broad, atrium slightly enlarged, very shallow, 8-11 quinquelocular 

 pores in atrium and on edge of opening and 11-24 similar pores extending from 

 spiracle to body margin in an irregularly single row, 22-35 in group and row 

 combined; multilocular pores, totaling 72-88 and with 10 loculi, arranged in 5 

 complete and 3 interrupted rows, the posterior row with 9-16 pores, penultimate 

 row with 7-14, next with 10-18, each of next 2 with 14-20, next with 2-5, and 

 each of next two rows with 2 or 3 ; 5-10 dark-rimmed 8-shaped pores each side of 

 beak, some scattered on anterior end and others tending toward arrangement in 



5 or 6 transverse rows posterior to mouth parts ; submarginal 8-shaped pores in 

 an irregularly single and double row terminating nearly twice length of apical 

 seta from bases of setae, usually as numerous as corresponding marginal 

 8-shaped pores, the row single posterior to marginal 8-shaped pores ; submarginal 

 setae in a complete row terminating near the fourth to sixth posteriormost pair 

 of marginal 8-shaped pores; 2 pairs of setae in the posterior row of multilocular 

 pores and 1 pair in each of the next 2 rows. 



Apex of abdomen: Notch present; lobes indicated; setae, apical apparently 45 

 (certainly not more than 50) n long, interapical 14.4-16.2 n long, dorsal 7.2 ix 

 long, intermediate ventral 2.8-3.6 fi long, outer ventral 5.4 fi long; anal ring with 



6 setae 36-41 /x long, with an inner row of 6 and an outer one of 15 or 16 pores. 

 divided on dorsal side and tending toward division on ventral ; ventral surface of 

 apex sclerotized and rugose, or sclerotized in dentate rows. 



Larva. — Rather elongate elliptical, but the ends somewhat narrowed. 



Margin : 8-shaped pores probably 28 in number, but posterior pair more nearly 

 on dorsal surface than on margin and appearing to belong with dorsal lateral 

 pores rather than with marginal pores, the posterior pair slightly larger than the 

 5 pairs anterior to it, the next 7 pairs slightly larger than the 5 behind them, 

 slightly smaller than the anterior pair, and of the same size as the posterior pair.
