SCALE INSECTS OF THE GENUS PARLATORIA al 
Tuller material of this insect has been available for study, but again, 
thanks to George Compere’s collecting, specimens from both the 
type hosts from Western Australia, as well as from other hosts in 
Australia, have been studied with the resultant conclusion that the 
name petrophilae Fuller can properly be included as one of the 
synonyms of pittospori Mask. 
Adult female—Eyespot small but usually distinct, approximately circular, 
more or less protruding to almost stout conical. Each anterior spiracle with 
2 to 5 disk pores adjacent, average number in specimens tabulated 2.6; posterior 
spiracle without derm pocket between spiracle and margin and, so far as 
noted, without tubular ducts near spiracle in this area. Duct tubercles of 
medium size, ranging from rather acutely short conical anteriorly to elongate 
and hardly conical posteriorly ; numbers in the specimens tabulated as fellows: 
Prespiracular, range 2 to 6, average 4; anterior spiracular, range 3 to 12, aver- 
age 5.65; intermediate, range 1 to 8, average 3.1; posterior spiracular, range 
1 to 7, average 2.3; first abdominal, range 1 to 7, average 4; totals, one side 
of body, range 10 to 24, average 21. Dorsal submarginal tubular ducts inter- 
mediate in number, tabulated range for each side of body 35 to 68, average, 
in specimens examined critically, 48. No cicatrices observed on dorsum of 
first abdominal segment. No special sclerotic flecks noted on pygidium. Both 
macroducts and microducts on intermediate dorsal areas of pygidium, usually 
1 to 4 macroducts above each anterior lateral paragenital pore cluster, and 
1 to 5 on segment immediately preceding this, sometimes with 1 to 3 smaller 
macroducts on segment anterior to this; or with microducts at this point and 
in varying numbers on anterior abdominal segments, also sometimes between 
intermediate ducts of each segment;-. very rarely with a duct on each side on 
pygidium within frame of paragenitals. The three median pairs of lobes fully 
developed as usual, moderate in size, graded somewhat in size from median 
to outer, all usually more or less distinctly notched on both inner and outer 
margins; fourth and fifth lobes represented by membranous extensions of 
pygidial margin closely simulating the adjacent plates as in proteus, but vary- 
ing considerably in size, shape, and extent of fimbriation in the specimens 
examined. Plates between the fully developed lobes and beyond these to fifth 
lobe much as in other species; those beyond fifth lobes broad toward base, 
tapering toward apex, but each usually with basal constriction and irregularly 
truneate apex. Paragenitals fairly numerous, in 4 groups, adjacent ends of 2 
groups on each side often close together; pore numbers in material studied 
critically: Anterior laterals 6 to 18, average 10; posterior laterals 7 to 15, 
average 11.25; totals 35 to 61, average 43.3. 
The preceding conclusions on synonymy and the descriptive notes 
have been based on a considerable accumulation of specimens, the 
bulk of which come from the extensive coccid collections presented to 
the Bureau of Entomology by George Compere in 1911. Most of 
the specimens studied are from Australia and include examples from 
Maskell’s type material of pittospori (Maskell collection No. 123) 
and of myrtus (Maskell collection No. 136) and immature specimens 
from the type material of Fuller’s dryandrae. Material from other 
sources includes specimens on Pittosporum undulatum (Pittospora- 
ceae), Australia, Koebele collection, Myrniong, Victoria, September 
1899, J. Lidgett (No. 191) ; Pittosporum sp., Sy dney (No. 392), West 
Maitland, New South Wales (No. 629), Norova, New South Wales 
(No. 659), Perth, Western Australia (No. 2022); on Banksia sp. 
(Proteaceae), Swan River, Western Australia (Nos. 806 and 933) ; on 
Dracaena draco (dragon’s blood tree) (Liliaceae), Svdney (No. 254) ; 
on Dryandra sp. (Proteaceae), Swan River, Western Australia (No. 
871); on Hakea sp. (Proteaceae), Albany (No. 1009), Swan River, 
Western Australia (No. 807), and unspecified locality (No. 873) : on 
laurustinus (Viburnum tinus) (Caprifoliaceae), Sydney (No. 238), 
all collected by George Compere; on J/acrozamia corallipes (Cycada-
