THE SCALE INSECT GENUS ASTEROEECANIUM 199 



Test of male.— Elliptical, 0.8 rum. long, 0.r> wide: slightly convex dorsally, with 

 longitudinal median and lateral carinae and rather indefinite transverse stria- 

 tums; flat ventrally: pale greenish yellow, transparent, very thin: marginal and 

 dorsal filaments rubbed off. 



Adult indie. — 0.7 mm. long. 



Head: Antennae broken: characters indeterminable. 



Thorax: Bar between wing bases curved on anterior margin, with a fold in 

 center, three times as long as wide ; tibia and tarsus broken off. 



Abdomen: Five segments each with a seta dorsally on lateral margin: 4 seg- 

 ments each with a seta in ventral submedian area; each lobe area with 1 long 

 and 3 short setae ; penis sheath apparently with 4 setae on dorsal surface near base 

 and 14 on each side of ventral opening. 



Male nymph. — Antenna 10-segmented ; other characters indeterminable. 



Data. — Described from unmounted specimens (paratypes) and the 

 following mounted material: Six females from Citrus sp., Java, G. 

 Compere, Compere Xo. 514, holotype and paratypes; 1(5 females, 4 

 second-stage specimens, 24 larvae. 2 fragmentary adult males, and 1 

 male nymph from Citrus sp., Singapore. Straits Settlements, from 

 T. H. Burkill. January and June' 1924. paratypes; 1 female from 

 pomelo, Batavia. Java, intercepted at Boston. Mass.. O. A. Hardy, 

 July 8. 1934. paratypes; 5 females and 8 larvae from Citrus sp.. "Pasar 

 Minggoe," Java. C. Franssen collector, 1936, from K. G. E. Kalshoven, 

 paratypes. 



Most of the host material has been heavily infested with this scale, 

 and the majority of the insects have been severely attacked with fungus. 



ASTEROLECANIUM STYPHELIAE (Maskell) 

 (Fig. 68. L-P; pi. 6, A) 



Described by Maskell in 1892 (69, pp. 24,-25) as Planchonia styphe- 

 liae from Styphelia richei and Leptospermum jumiperinum from Aus- 

 tralia, supplied by Mr. French. 



Hal it. — Living on both surfaces of leaves. 



Test of female. — Elongate ovoid. 1.5-2 mm. long. 1-1.5 wide: convex dorsally, 

 sometimes with a faint longitudinal median carina and transverse striationa ; 

 flat ventrally: pale brownish yellow, transparent, thin, shiny: marginal filaments 

 white: elliptical larval exit in ventral surface at margin. 



Adult female. — Elongate ovoid. 1-1.7 mm. long, 0.9-1.3 wide. 



Margin : 8-shaped pores in a single row terminating two to three times a pore's 

 length from bases of apical setae, posterior pores 9 y. long and 5 wide, the others 

 11-12 m long and 7 wide, from less than a pore's width to slightly more than the 

 length of a pore apart : quinquelocular pores in a single row terminating within G 

 8-shaped pores from end of row of those pores, slightly more numerous than corre- 

 sponding 8-shaped pores. 



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

 sparse ; tubular ducts 2S m long. 



Ventral surface: Antenna thimble-shaped, with 2 setae slightly shorter. 1 much 

 shorter, and 2 slightly longer than diameter of antenna : 1-7 quinquelocular 

 pores between antenna and margin: beak witli 2 pairs of setae: spiracular bar 

 fairly broad, 5-12 quinquelocular pores extending from spiracle to body margin 

 in a single row; multilocular pores, totaling r>4-71 and with 8-10 loeuli, in 6 

 complete and 3 or 4 interrupted rows, the posterior row with 5-7 pores, each 

 of The next 2 with 10-12. next with 10-15, next with S 12. next with 5-8, next 

 with 2 7. each of the next 2 with 2-4. and next (if present, anterior to posterior 

 Spiracles) with 2: 1 or 2 dark-rimmed 8-shaped pores each side of beak, ;> few 

 scattered on anterior end. and others arranged in 2 transverse rows among 

 multilocular pores: submarginal 8-shaped pores in a row which is usually 

 single, although occasionally double for a few pores, and terminating aear penulti- 

 mate row of multilocular pores, the pores as numerous as marginal 8-shaped 

 pores; submarginal setae in a complete row terminating near penultimate pair 

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

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