THE SCALE INSECT GENUS ASTEROLECANIUM 181 



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

 (VI i. (VII), (VIII). (IX. X). (I). (II); antenna! setae. I. 0; II. III. 5 or 0: 

 IV- X. 15-20; X also with 4 very long setae; basal bars diagonal; or s setae 

 anterior to ventral eyespots. 



Thorax: Bar between winy bases rectangular, five times as long as wide, 

 with a faint median longitudinal fold and a small clear area in center; tibia very 

 slightly longer than tarsns. 



Abdomen: Five segments each with a seta dorsally on lateral margin, appar- 

 ently 3 segments each with a seta in ventral lateral area: lobes sometimes 

 indicated, each with 1 long and 2 short setae; penis sheath with 1 pair of setae 

 dorsally at base, also apparently with 1 pair ventrally at base, and with a few 

 setae on each side of ventral opening. 



Male nymph. — Distinguishing characters similar to those of adult male. 



Third-stage male. — Resembling adult female but smaller: margin with 8-shaped 

 pores in a single row continuous between apical setae, trilocular pores termi- 

 nating slightly before apical setae, slightly more numerous than corresponding 

 8-shaped pores at posterior end. absent at anterior end: ventral surface with 

 antenna thimble-shaped. 7 trilocular pores between spiracle and body margin, 

 sometimes 1 or 2 dark-rimmed 8-shaped pores near month parts, legs repre- 

 sented by 3 pairs of very small sclerotized areas : apex of abdomen with anal 

 opening slightly nearer margin than in female, setae shorter than in female. 



Data. — Described from specimens (30 females. 7 larvae. 4 adult 

 males. 1 male nymph, and 1 third-stage male, mounted) on Sabal pal- 

 metto, Cayamas. Cuba. E. A. Sclrwarz, June *23. 1904, holotype and 

 paratypes. 



The specimens of palm examined are very heavily infested. 



ASTEROLECANIUM SANBERNARDENSE Heilipel 



(Fig. 01. F-J : pi. 4, G) 



Described in 1937 (J/, pp. 18-19). 



Habit. — Living on the lower surface of leaves, in shallow or fairly deep pits. 



Test of f t nmlc. — Usually circular, sometimes slightly longer than wide. 1.5-2 

 mm. in diameter, or 1.5-2 mm. long and 1.25 wide; flat dorsally. without, or with, 

 a faint longitudinal median carina and transverse striations; slightly to rather 

 strongly convex ventrally: greenish yellow, transparent, very thin, shiny, 

 punctate: marginal filaments pale greenish yellow: elliptical larval exit in 

 margin. 



Adult female. — Nearly circular or slightly longer than wide, posterior end 

 slightly produced: 1.25-1.75 mm. in diameter or 1.25 mm. long and 1.10 wide. 



Margin: 8-shaped pores in a single row terminating length of an apical sera 

 from ba<es of setae. 11' fx long and 8 wide, around a pore's length apart: 

 Quinquelocular pores in a single row terminating at a point near the fifth to 

 the fourteenth 8-shaped pore from end of row. nearly as numerous as corre- 

 sponding 8-shaped pores near end of row. usually about one and a half times 

 as numerous as that elsewhere. 



Dorsal surface: Minute 8-shaped pores numerous: disk pores fairly sparse: 

 tubular ducts 32 ,u long. 



Ventral surface: Antenna an irregular. Hat area on derm, with -\ setae longer 

 and 1 slightly shorter than diameter of antenna : 1 or 2 quinquelocular pores 

 between antenna and margin: beak with 2 pairs of setae: spiracular bar greatly 

 expanded at inner end: wrinkles in derm around spiracular opening: 35-55 

 quinquelocular pores extending from spiracle to body margin in an irregularly 

 double row: multilocular pores, with 10 loculi, in ." complete and 4 interrupted 

 rows, the posterior row with 12-14 pores, penultimate row with 12-24. next with 

 10-24. next with 15-18, next with 14-10. next with 10-12, next with 12. next 

 with 4-ln. and anterior row with 2-4. the total 98-130; sometimes 1 or 2 dark- 

 rimmed 8-Shaped l*>res each side of beak, a few scattered on anterior end. 

 and others arranged in or 7 transverse rows posterior to mouth parts; sub- 

 marginal 8-shaped pores in an irregularly single row terminating near posterior 

 row of multilocular pores, somewhat less numerous than corresponding marginal 

 8-shaped pores; submarginal setae in a complete row terminating nearly directly
