THE SCALE INSECT GENUS ASTEROLECANIUM 215 



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



ducts 28 fi long. 



Ventral surface: Antenna thimble-shaped, apparently with 2 setae as long as 

 diameter of antenna; beak apparently without setae: spiracle with bar slightly 

 expanded at inner end, atrium enlarged, bag-shaped, and containing 8-11 

 quinquelocular pores, apparently without pores extending from spiracle to body 

 margin; multilocular pores, totaling 35 and with 10 loculi, in 3 complete and 2 

 interrupted rows, the posterior row with 13 pores, next with 11. next with 7, and 

 each of the others with 2 ; 4 or 5 dark-rimmed 8-shaped pores each side of beak, 

 a few in an irregular longitudinal lateral row. and others tending toward 

 arrangement in 3 transverse rows among multilocular pores; submarginal 

 8-shaped pores apparently in a single row. terminating near posterior row of 

 multilocular pores, about half as numerous as corresponding marginal 8-shaped 

 pores ; submarginal setae in a complete row terminating somewhat anterior to 

 apical setae ; 2 pairs of setae in posterior row of multilocular pores and 1 pair in 

 each of the next 3 rows. 



Apex of abdomen : Lobes indicated, on ventral surface : setae, apical 64 n long, 

 one 1 /j. long anterior to apical on 1 side of single specimen examined : anal open- 

 ing indeterminable (probably because specimen is weakly stained ) ; ventral 

 surface of apex slightly sclerotized in dentate rows. 



Data. — Described from one test (destroyed in mounting adult) 

 and one mounted female from Calamus sp.. Tavabas Province, Luzon, 

 Philippine Islands, B. Acedillo, April-May 1915, U. S. N. H., holotype. 



This species resembles hitti, but differs from it in having the atrium 

 of the spiracle greatly enlarged and containing 8 to 11 quinquelocular 

 pores, in apparently lacking pores between spiracle and the body 

 margin, in having only about 35 multilocular pores and apparently 

 a single instead of a double row of submarginal 8-shaped pores, and in 

 lacking interapical setae. 



Asterolecanium urichi Cockerell 



(Fig. 77, G-Nj pi. 6, C) 



Described in 1894 (18, p. 308). 



Habit. — Living on leaves, nuts, and bark. 



Test of female. — Elongate, margin sometimes indented by growth against 

 hairs on leaf ; 1-1.5 mm. long, 0.5-0.75 wide : nearly flat to slightly convex 

 dorsally, rarely with a faint longitudinal median carina; flat ventrally; brown- 

 ish or greenish yellow, sometimes very pale, transparent, faintly punctate ; 

 marginal filaments rich light brown, rarely with a pale-salmon cast; elliptical 

 larval exit in dorsal surface at margin. 



Adult female. — Elongate, around 1 mm. long. 0.6 wide. 



Margin: 8-shaped pores in a single row terminating about one-third length 

 of apical seta from setal bases, 8-9 n long and 5 wide, usually about a pore"s 

 width apart, but the posterior 2 or 3 pores sometimes more widely separated: 

 trilocular pores in a single row from nearly opposite antennae to about halfway 

 between posterior spiracular pore bands and posterior pair of 8-shaped pores, 

 rarely extending nearer posterior end of body, about as numerous as correspond- 

 ing 8-shaped pores at each end of row. approximately twice as numerous as 

 that elsewhere. 



Dorsal surface: 8-shaped pores normally lacking but 3 or 4 noted rarely. 12 n 

 long and 8 wide; minute 8-shaped pores fairlv numerous; disk pores sparse; 

 tubular ducts 24 /z long. 



Ventral surface: Antenna a circular, raised area, with 2 short setae and 2 

 that are slightly longer than diameter of antenna : beak with 2 pairs of setae : 

 spiracle with bar narrow, slightly expanded at inner end. atrium enlarged, 

 bag-shaped, and containing 6-16 (usually 6-10) quinquelocular pores, 10-15 

 similar pores extending from spiracle to body margin in an irregularly single 

 or double row: a group of 8-18 dark-rimmed 8-shaped pores each side of beak 

 and 8-1(1 posterior to mouth parts; submarginal 8-shaped pores in a single vow 

 terminating near third or fourth 8-shaped pore from end of row, about one-
