Orthezia; derm pores of the usual 
quadrilocular type, occurring singly, 
or frequently in clusters or strings of 
from 2 to 5, these pores relatively 
large and most numerous between the 
ends of the dorsal, marginal, and ven¬ 
tral spine bands; outer margin of 
ovisac band and anterior margins of 
transverse spine bands inclosed by 
ovisac band with a single row of much 
smaller quadrilocular disk pores set at 
inner ends of short tubular ducts; ovi¬ 
sac band with a scattered row of larger 
disk pores along outer margin of at 
Preadult female. —Rather closely 
resembling the adult, except for the 
absence of the ovisac band and the 
reduction in the development of some 
of the structures associated with it. 
No other stages have been available 
for examination. 
The species has been described from 
two adult females, one mounted, the 
other unmounted, from four mounted 
preadult females, all collected at San 
Antonio do Sul, Oriente Province, 
Cuba, by Dr. W. M. Mann in 1920, 
and from another mounted immature

adult), X 115; C, quadrilocular disk pores, X 1,500; D, eyestalk, X 1,500; E, anal ring showing pores 
and setae (from preadult), X 500; F, section through anterior median portion of ovisac band, X 500;

least the anterior section; derm spines 
arranged in bands and clusters about 
as shown in figure, with 9 dorsal and 
11 marginal groups on each side, the 
individual spines w T ith very slightly 
swollen, more or less distinctly truncate 
apices; with a crowded cluster of small 
conical spines in the genital region; 
with the body setae relatively numer¬ 
ous and large, particularly in the ven¬ 
tral abdominal region; anal ring stout, 
nearly circular, with 6 setae and pores, 
but the exact character and arrange¬ 
ment of these not determinable from 
the material available.

This genus may be characterized as 
follows as regards the adult female: 
External appearance of body in gen¬ 
eral resembling that of other genera 
of the subfamily; that is, bearing plates
