THE SCALE INSECT GENUS ASTER OLE CANIUM 103 



found in other species having 6 setae on the anal ring. Among the 

 larvae of species having 6 setae on the anal ring, that of gutta is the 

 only one known with less than 26 marginal 8-shaped pores. Like the 

 adult, the larva is unusual in not having an anal opening and tube 

 definitely differentiated from the surrounding derm. 



ASTEROLECANIUM HAKEAE Fuller 



(Fig. 29, G-J; pi. 8, 0) 



Listed by Fuller in 1897 (36, p. 13If5) as Planchonia hakeae but 

 described by him in 1899 (37, p. ^56) as Asterolecanium hakeae. 



Habit. — Living on bark in shallow pits. 



Test of female.— Nearly circular, 1-1.35 mm. in diameter; slightly convex 

 dorsally, with or without faint transverse striations, convex ventrally ; greenish 

 yellow, transparent, smooth or slightly rough, shiny ; marginal filaments whitish, 

 fragmentary in available specimens; ellip'.ical larval exit in margin. 



Adult female. — Nearly circular, 0.9-1.25 mm. in diameter, posterior end some- 

 times slightly produced. 



Margin : 8-shaped pores in an irregularly double row on anterior five-sixths 

 of body or less, and in a single row on at least posterior sixth, terminating around 

 the length of apical seta from bases of setae, individual pores measuring 10-12 fi 

 long and 7 wide, usually around a pore's length apart, pores of the 2 rows alternate 

 or opposite, in the latter case less than a pore's width apart ; quinquelocular pores 

 in a single row terminating near the penultimate or posterior pair of 8-shaped 

 pores and as numerous as those ; disk pores ventrad of quinquelocular pores, 

 terminating near the posterior pair of marginal 8-shaped pores and less numerous 

 than those pores. 



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

 ducts 26 v long. 



Ventral surface: Antenna bluntly conical, with 1 seta shorter and 1 slightly 

 longer than diameter of antenna ; 4-6 quinquelocular pores between antenna and 

 margin ; beak apparently with 1 pair of setae ; spiracular bar rather broad ; 10-16 

 quinquelocular pores extending from spiracle to body margin in a single row ; 

 multilocular pores, totaling 101-116 and with 9 or 10 loculi, arranged in 5 com- 

 plete and 5 interrupted rows, the anterior row anterior to posterior spiracles, 

 posterior row with 8-12 pores, penultimate with 11-18, each of next 3 with 16-24, 

 each of next 3 with 6-8, each of next 2 with 3-6; dark-rimmed 8-shaped pores 

 rather sparse, a few scattered on anterior end and others tending toward ar- 

 rangement in 2 or 3 transverse rows on abdomen; submarginal 8-shaped pores in 

 an irregularly double row terminating near the penultimate row of multilocular 

 pores, about half as numerous as marginal 8-shaped pores; submarginal setae 

 in a complete row terminating between the posterior pair of marginal 8-shaped 

 pores and apical setae; 3 or 4 setae in posterior row of multilocular pores, 2 

 in penultimate row, and 1 or 2 in first row anterior to penultimate. 



Apex of abdomen : Notch present ; setae, apical 47 fi long, interapical 9 n long. 

 inner ventral 3.6-5 n long, outer ventral 7.2 fi long; anal ring with 6 setae around 

 30 fi long and an inner row of 6 and an outer one of 16 pores, divided on dorsal 

 and ventral sides ; ventral surface of apex lightly sclerotized and lined. 



Data. — Redescribed from unmounted material and the following 

 mounted specimens: Four females on Hakea ilicifolia, Swan River, 

 West Australia, 1891, type material; eight females on Banksia sp., 

 Swan River, Australia, G. Compere, Compere No. 940 ; six females on 

 Acacia sp., Melbourne, Australia, G. Compere, Compere No. 344; one 

 female on Acacia sp., Australia, C. French collector, from E. E. Green, 

 received in 1934. 



Closely related to ventruosum but differing in having the marginal 

 row of 8-shaped pores irregularly double in spots instead of definitely 

 double around most of margin, in having fewer marginal quinque- 

 locular pores, and in lacking a row of disk pores dorsad of the marginal 

 8-shaped pores.
