Scale Insects of the Subfamily Ortheziinae 
139 
apex rounded, average length about 
43 microns, width at base 50 microns; 
legs characteristic for the genus, tarsal 
claw nearly straight, fairly stout, with 
2 distinct and sometimes 1 indistinct 
denticle within, claw digitules relatively 
slender; beak not unusual, length of 
that of an average specimen 196 
microns, width at base 175 microns; 
1-segmented, with only a faint fold 
about one-third of length from base 
suggesting a j oint; thoracic spiracles 
not unusual, with a cluster of spines 
of normal shape and size around the 
opening of each; abdominal spiracles 
short and relatively stout, very ob¬ 
scure, owing to the close crowding of 
the body spines; exact number not 
absolutely determinable, but appar¬ 
ently with 4 pairs, these the 4 posterior 
ones; derm pores, so far as observed, of 
the one characteristic quadrilocular 
disk type only, occurring sparingly, 
except in the midventral abdominal 
region, here in rather closely set, irregu¬ 
lar, transverse rows, particularly around 
the genital opening, and these last 
pores somewhat larger and less heavily 
chitinized and with a wider marginal 
rim than those occurring dorsally and 
laterally; body with scattered setae 
dorsally and laterally, in more or less 
distinct relation to the spine clusters, 
and with a distinct transverse cluster 
of setae of varying sizes just anterior 
to the genital opening, as well as with 
indistinct transverse rows of such 
setae anterior to this cluster; body 
spines distinctly set off in groups cor¬ 
responding to the secretion as already 
described, the disk of the dorsum with 
10 paired transverse clusters on the 
head, thorax, and abdomen, of which 
the first 4 are distinctly larger and 
broader than those on the abdomen; 
marginal spines, including the anterior 
head clusters and the posterior ab¬ 
dominal one, in 11 clusters on each side 
of the body, these placed more or less 
directly opposite the ends of the cor¬ 
responding transverse dorsal clusters; 
anterior section of ovisac band rela¬ 
tively broad, accompanied only by a 
single row of scattered quadrilocular 
disk pores, lateral and apical sections 
of this band somewhat narrower, like¬ 
wise accompanied only by the single 
row of pores, this band interrupted 
laterally by narrow, diagonal clear 
areas, and inclosing, in the midventral 
abdominal region, 3 narrow, curved, 
widely separated, transverse rows of 
short spines; with clusters of spines 
around the openings of the thoracic 
spiracles , but none of these unusual 
in shape; also with clusters and patches 
of spines around the coxae; anal ring 
of normal form for the genus, the 
inner margin of the pore band on each 
half strongly angulate within anteriorly 
and posteriorly, the angulate tongues 
nearly inclosing a membranous area 
at each end of the ring; with the usual 
6 anal ring setae. 
Larva. —Ovate, tapering somewhat 
behind, average length 464 microns, 
average width 303 microns, eyestalk 
short tuberculate, antennae not unusual, 
lengths of segments of one in microns 
as follows: I, 32; II, 39; III, 43; IV, 50; 
V, 50; VI, 121; spine, 21; legs normal, 
fairly stout, tarsal claw with 2 promi¬ 
nent denticles on the apical half, and 
frequently with a somewhat less con¬ 
spicuous one about the middle, claw 
digitules set alike, and not over one- 
fourth the length of the claw; beak 
elongate conical, average length about 
93 microns, average width at base about 
71 microns; thoracic spiracles not un¬ 
usual; abdominal spiracles apparently 
in 4 pairs as in adult; with a few scat¬ 
tered derm pores, these forming short, 
indefinite, median transverse segmental 
rows dorsally in the thoracic region; 
body with a few, apparently scattered, 
setae and numerous spines, the last ar¬ 
ranged in definite clusters dorsally and 
on the abdomen ventrally, the median 
and marginal dorsal groups closely ap¬ 
proaching each other, so that there ap¬ 
pears to be an almost continuous 
transverse band of spines on each seg¬ 
ment; ventral rows of spines on abdo¬ 
men narrower, with the spines less 
numerous and more scattered; ring not 
unusual for the genus. 
This species has been described from 
two mounted adult females from 
Elfers, Fla., on Spanish moss (Til- 
landsia usneoides) (Bromeliaceae), col¬ 
lected July 12, 1917, and forwarded by 
C. E. Wilson (holotype and paratype), 
and from six mounted adult females, 
five mounted larvae, and a number of 
unmounted specimens from Motes 
Station, Fla., on Tillandsia usneoides, 
collected by H. W. Fogg, October, 1921, 
and July, 1922, and kindly forwarded 
for study by G. E. Merrill of the Florida 
State Plant Board (paratypes). Ma¬ 
terial from Gainesville, Fla., collected 
July, 1924, by Hart arid Merrill, has 
also been reported. 
The types are in the United States 
National Collection of Coccidae. Para¬ 
types are in the collection of the Florida 
State Plant Board.
