SCALE INSECTS OF THE GENUS PARLATORIA 7 
marginal macroduct opening between median lobes. Submarginal dorsal tubu- 
lar ducts rather numerous, extending from apex of pygidium to anterior end 
of abdomen, size gradually reduced anteriorly, 74 to 84 in number in specimens 
tabulated. Intermediate dorsal macroducts present and numerous on each 
side, a cluster of 4 to 5 within the frame of the paragential pore clusters, one 
of 6 to 7 above the anterior lateral paragenitals, and a cluster on each of the 
3 segments anterior to this, the numbers running 9 to 11, 5, 3; in addition 
with 2 to 4 median clusters of ducts, 2 ducts above the median paragenitals 
and 1 or 2 on 1 to all of the 3 segments anterior to this; no dorsal microducts 
noted in association with these. No dorsal abdominal cicatrices located. No 
dorsal submarginal sclerotized flecks noted on any of the abdominal segments. 
Three pairs of lobes plainly developed and sclerotized, the first contiguous at 
bases; the first and second characteristically elongate, strongly protruding, 
each lobe deeply notched once on outer side, with entire inner margin; third 
lobes much less prominent, sclerotized portion wider than long, posterior edge 
diagonal and normally plainly tridentate; fourth lobe suggested by a small, 
barely protruding, faintly sclerotized, somewhat fringed process on each side 
of pygidium, so inconspicuous and poorly developed that it hardly deserves to 
be called a lobe. Plates slender, almost ligulate, continuing along body mar- 
gin onto anterior abdominal segments; posterior plates fringed apically, an- 
terior plates much suggesting gland spines; normally 4 plates between third 
and rudimentary fourth lobes, the third of these usually largest of all; plates 
between median lobes 2, very narrow, and obscure. ParagenitalS numerous, 
in 5 groups; range in numbers in 6 specimens tabulated as follows: Anterior 
median 6 to 16, anterior laterals 18 to 26, posterior laterals 16 to 28, totals 
85 to 113. 
Of the forms discussed here, this species perhaps most nearly re- 
sembles Parlatoria cinerea, but differs from all these in the ap- 
parently consistent absence of the median marginal macroduct. be- 
tween the median lobes and in the possession of intermediate dorsal 
macroducts both within the frame of the paragenitals and anterior 
to the pygidium proper. 
These notes are based on specimens from the Maskell collection 
(No. 474) and from Victoria, Australia, on Banksia integrifolia, 
collected by C. French and received from E. E. Green in 1916. 
PARLATORIA BLANCHARDI (Targioni Tozzetti) 
(PI 1B; pl. 7, B= pl. 10) B) 
This insect was recently redescribed in careful detail by Stickney 
(49) and is discussed here to record confirmation of previously sug- 
gested synonymy and to include it in the key to species and among 
the illustrations. Any serious student of the genus should consult 
Stickney’s paper on the anatomy of this species. 
It has been possible to confirm the synonymy of Parlatoria proteus 
variety palmae Maskell (47, p. 229) with this species through com- 
parison of specimens from the Maskell collection (No. 597) with 
others from elsewhere in the world. The practical certainty of such 
synonymy was indicated by Leonardi (33, p. 47) and by Cockerell 
(10, p. 156), but no previous verification of it has been noted in 
literature. In this connection, no success has been attained in inter- 
preting the remarks by Froggatt (21, p. 602) respecting the occur- 
rence of P. proteus on date “palm in Australia. It seems necessary 
to conclude that Maskell’s description of the Australian date palm 
specimens was overlooked by Froggatt. Incidentally, the Maskell 
reference cited by Froggatt apparently relates to page 213 of volume 
25 of the Transaction of the New Zealand Institute, published in 
1893, rather than to page 231 of a volume published in 1887. Buxton
