quently very slightly thickened at a 
point corresponding with the usual 
location of the outer denticle; beak 
rather long conical, 1-segmented, with 
a faint suggestion of a joint sometimes 
visible near the base; thoracic spiracles 
not unusual, each opening in a spine 
cluster, without a definite spine collar 
around the opening, but with a fairly 
distinct band of disk pores surrounding 
each opening; with 7 pairs of very short 
tubular abdominal spiracles; derm 
pores of the usual quadrilocular disk 
type only, these occurring both dor- 
sally and ventrally, particularly in the 
interspaces between the spine bands; 
derm with scattered, slender setae both 
dorsally and ventrally; derm spines 
arranged in 10 marginal and 10 dorsal, 
compact, closely crowded clusters, 
with the second, third, and fourth 
dorsal bands completely interrupted 
medially by broad, triangular, simi¬ 
larly crowded spine clusters set off 
from the remainder of the band on each 
side by narrow diagonal clear strips, 
these last clusters evidently forming 
the 3 triangular wax plates of the per¬ 
fect insect; ventral ovisac band stout 
anteriorly, somewhat narrowed later¬ 
ally and interrupted by several clear 
spaces; anal ring oval, with the pore 
bands on each half united at anterior 
and posterior apices, and each very 
strongly angulate along the inner 
margin at three points, one opposite 
each anal ring seta; the usual 6 anal 
ring setae rather long and slender. 
This species has been redescribed 
from the following material: West 
Cliff, Custer County, Colo., in nests of 
Formica Integra, coll. T. D. A.Cockerell, 
1889 (cotype); Beulah, N. Mex., coll. 
T. D. A. Cockerell, March, 1900; the 
same, no date, coll. Miss W. Porter; 
Kaslo, British Columbia, on roots of 
trees and grass amongst rotten wood, 
coll. J. W. Cockle, April and May, 
1908; Corte Madera Creek, Stanford 
University, Calif., on Eriophyllum con - 
fertifolium (Compositae), coll. M. N. 
Reeper, October, 1916; Boulder, Colo., 
on Castilleia sp. (Scrophulariaceae), coll, 
at quarantine, Washington, D. C., by 
H. F. Dietz, June 8 and 12, 1917; near 
Eldorado, Colo. (9,000 feet), coll. 
T. D. A. Cockerell, October 1, 1922. 
The following are the additional pub¬ 
lished distribution records for the 
species: Colorado, near Fort Collins; 
New Mexico, at Trout Springs; Cali¬ 
fornia, in Marin County. There are 
no other published host records, al¬ 
though the species has been reported 
as occurring in ants' nests. 
GENUS NEWSTEADIA GREEN 
Reference. —Green, 1902, Ent. Mo. 
Mag. 38: 284-285. 
The following ' diagnosis may be 
given for this genus: 
Adult female. —Completely cov¬ 
ered externally with depressed or flat¬ 
tened tufts or plates of secretion, much 
as in Orthezia; ovisac, when fully de¬ 
veloped, about as long as the body; 
derm without definite chitinization ex¬ 
cept for a transverse median plate in 
the posterior ventral abdominal region 
in one species; antennae normally 6 to 
7 segmented, the 2 basal segments very 
much enlarged and elongated as com¬ 
pared with Orthezia; eyestalk elon¬ 
gate, curved, fingerlike; legs similar to 
those of Orthezia, except for the com¬ 
plete fusion of the tibia and tarsus in 
each, the joint indicated only as a more 
or less distinct transverse line near 
base; beak 1-segmented, rather elongate 
conical, rounded at apex; with the usual 
2 pairs of thoracic spiracles and with 5 
anterior pairs of abdominal spiracles, 
the posterior pairs wanting; derm 
pores of the quadrilocular disk type; 
derm setae occurring occasionally over 
body and in a distinct cluster ventrally, 
anterior to the genital opening; body 
spines arranged in marginal and dorsal 
clusters as in Orthezia, but most of the 
marginal abdominal clusters fused into 
a conspicuous band; anal ring with 
the usual pore bands and 6 setae, the 
latter rather short, stout, and blunt- 
tipped as compared with Orthezia. 
Larva. —Very similar to that of 
Orthezia, differing primarily in the pos¬ 
session of only 4-segmented antennae. 
Adult male. —Not exhibiting any 
characters that‘will plainly segregate 
males of this genus from those of 
Orthezia. 
This genus has previously been rep¬ 
resented by only a single species, this 
occurring naturally in various parts of 
Europe, and, presumably through acci¬ 
dental introduction and under rather 
peculiar circumstances, in one place in 
Australia. A second, American, species 
is described below. This genus, exclud¬ 
ing the Australian record, therefore 
has a holarctic distribution, and a 
majority of the records appear to be 
from northern localities or rather high 
altitudes, an apparently conspicuous 
exception to this being the principal 
record on which the new American 
species is based, this being from an 
altitude only a little above sea level, 
and latitude 39 degrees north. The 
original collector of the species has
