Reference. —Cockerell, 1901, 
Canad. Ent. 33: 209. 
Adult Female.—No specimens 
available for description of external 
appearance, the following therefore 
copied from the original description 
“about 2 mm. long; pale orange; ovi¬ 
sac (in specimens seen) not very long; 
two very long median white caudal 
lamellae, about two-thirds length of 
body, curving over ovisac, but not 
attached to it. Dorsum covered with 
waxy secretion, but it is so easily de¬ 
ciduous that I have never found an 
adult with it sufficiently in place to 
describe,” body membranous except for 
a definite chitinous patch attached to 
each side of the anal ring as in annae; 
antennae normally 7-segmented, 
lengths of one in microns as follows: I, 
107; II, 71; III, 107; IV, 71; V, 50; 
VI, 47; VII, 132; spine, 21; eyestalk 
conical, protruding, slightly curved; 
legs mutilated, structure uncertain; 
beak stout conical, 1-segmented, with 
an indistinct suggestion of a joint near 
base; thoracic spiracles set in a spine 
cluster and with a fairly distinct loose 
collar of spines around the opening of 
each; with 8 pairs of long tubular ab¬ 
dominal spiracles; derm pores of the 
quadrilocular disk type only, these oc¬ 
curring both dorsally and ventrally, 
usually in more or less distinct, but very 
scattered transverse rows, most abund¬ 
ant ventrally in the area inclosed by the 
ovisac band, fairly well chitinized, vary¬ 
ing only slightly in size; body with 
slender setae occurring occasionally 
both dorsally and ventrally, most 
abundant, but not distinctly clustered, 
in the area inclosed by the ovisac band; 
derm spines arranged in the usual dorsal 
and lateral marginal clusters about as 
shown in figure, the dorsal bands larger 
and continuous to the marginal clusters; 
ovisac band broad, made up of spines, 
with an irregular single row of disk 
pores along the inner margin, and, ante¬ 
riorly at least, an irregular double or 
triple row of similar pores along and 
Fig. 19 .—Orthezia lasiorum: Adult female, body, 
dorsal and ventral; X about 31 
within the outer margin; ovisac band in¬ 
closing 3 broad, heavy, and 2 narrower, 
lighter bands of spines and pores, the 
first 3 of these extending broadly to the 
ovisac band on each side; anal ring 
elongate oval, heavily chitinized, with 
a relatively narrow pore band on each 
half, this made up of comparatively few 
pores and indefinitely angulate anteri¬ 
orly and posteriorly, the 2 pore bands 
distinctly separated anteriorly and 
barely touching posteriorly, the middle 
of the outer face of each half of the anal 
ring with a protruding triangular chi¬ 
tinous wing, and just beyond this, on 
each side, 3 to 6 smaller, stout conical 
spines, this species differing, in the pos¬ 
session of the last, from all of the other 
species of the genus examined; anal 
ring with the usual 6 setae.
