Scale Insects of the Subfamily Ortheziinae 
153 
of wax secretion and a definite pos¬ 
terior ovisac; body stout oval; an¬ 
tennae actually 3- but apparently 
4-segmented, the terminal much the 
longest, the apical spine quite long and 
slender; apex of eyestalk cylindrical, 
its base apparently enlarged and form¬ 
ing a pseudobasal antennal segment; 
legs with tibio-tarsal articulation want¬ 
ing, the parts fused, the leg setae 
spinelike, in distinct rows on tibio- 
tarsus; beak 1-segmented, with a sug¬ 
gestion of a joint near base; each of 
the two pairs of thoracic spiracles 
opening in a spine cluster; abdominal 
spiracles not located in single specimen 
available for examination; derm pores 
mostly of the usual quadrilocular disk 
type, some in ventral region larger, 
apparently with 8 loculi; derm spines 
stout, swollen at bases and mostly 
distinctly capitate at apices, some, in 
a small cluster on each side of anal 
ring, but ventrally, oval in outline; 
body setae relatively large, but slender; 
anal ring with pores and 6 subequal 
setae; with a conspicuous transverse 
platelike thickening dorsally anterior 
to the anal ring. 
While the appearance of the antennae 
gives a very distinct impression that 
each is 4-segmented, the actual fact 
seems to be that each eyestalk is en¬ 
larged laterally in the form of a short 
chitinized cylinder, or is fused to 
such a dermal cylinder, which sup¬ 
ports the antenna. This conclusion 
is apparently verified by the fact 
that the small, double-walled circu¬ 
lar to oval pore, probably sensory in 
function, which, in the writer’s ex¬ 
perience, occurs constantly on or 
close to the distal margin of the 
second antennal segment is, in this spe¬ 
cies, found on what appears to be the 
third antennal segment. Shortly after 
the first publication of the description 
of this genus Maskell advanced the 
view that there were actually 4 seg¬ 
ments present rather than 3, as given 
in the description. Not long after this 
Sulc published a reply (in Bohemian), 
advancing additional reasons, appar¬ 
ently perfectly sound, for considering 
the proper number of segments to be 
3, and this last discussion has been 
made available to the present writer 
through the kindness of Mr. James 
Zetek, of the Ancon, Canal Zone, 
laboratory of the Bureau of Ento¬ 
mology, who translated all of its essen¬ 
tial parts into English. 
ORTHEZIOLA FODIENS GIARD 
Reference. —Giard, 1897, Comp. 
Rend. Soc. Biol. [Paris] 10: 583-585. 
This species was described from the 
island of Guadeloupe from the roots of 
a coffee tree. No specimens have been 
available for examination, and the 
characters given in the brief descrip¬ 
tion are inadequate as a basis for 
comparing this species with the others 
discussed here.

Synonym.- —0. signoreti Haller (see 
Lindinger, 1912, Die Schildlause, p. 
373). 
This species has been included in this 
paper on the basis of an examination of 
a single adult female, collected on rose 
bush from Malines, Belgium, at quar¬ 
antine, Washington, D. C., by R. D. 
Kennedy, May 16, 1922 (F. H. B. No. 
33632). It has also been recorded from 
Bohemia, England, Switzerland, and 
the Madeira Islands, either in ants' 
nests, from moss (Musci),or from grass 
roots (Gramineae), and it seems almost 
certain that the true host in the record 
given above was not the rose bush as 
recorded, but rather the moss used as 
packing around the rose plants.

This genus may be given the follow¬ 
ing diagnosis for the adult female: 
Superficial appearance much as in other 
Ortheziinae, actually resembling Orthe- 
zia insignis, body stout oval, derm 
membranous, antennae plainly 3-seg- 
mented; legs with the tibio-tarsal joint 
only very faintly suggested, these parts 
fused solidly; beak distinctly 2-seg- 
mented, long, only slightly tapering; 
with the usual 2 pairs of thoracic 
spiracles and with 6 pairs of abdominal 
spiracles, the two posterior pairs want¬ 
ing; derm pores mostly of the usual 
quadrilocular disk type, but some in 
the ventral abdominal area larger and 
with 6 loculi; body spines enlarged at 
bases, with apices almost truncate, but 
not swollen; body setae relatively large 
but slender; anal ring with pores and 
6 short setae, with the intermediate 
pair conspicuously smaller than the 
others.
