Scale Insects of the Subfamily Ortheziinae 
117 
ing only slightly in size and quite 
abundant as compared with many 
other species of the genus, occurring 
both dorsally and ventrally, particu¬ 
larly in the posterior portion of the 
area enclosed by the ovisac band, oc¬ 
curring here in crowded transverse 
bands of less heavily chitinized, some¬ 
what smaller pores; normal body spines 
arranged in groups about as shown in 
figure, these present in 11 marginal 
clusters including the anterior and 10 
ovisac band inclosing, besides the 
numerous pores already mentioned, 
apparently 4 fairly distinct transverse 
bands of rather elongate, slender 
spines; anal ring well developed, char¬ 
acteristic for the genus, with the inner 
margin of the band of numerous pores 
on each half distinctly but not con¬ 
spicuously angulate; ring normally 
bearing 6 fairly long setae. 
This species has been redescribed from 
a single adult female from Todos Santos 
Fig. 11 .—Orthezia boliviano ,: Adult female, body, dorsal and ventral; X about 31 
dorsal transverse bands on each half of 
the body; conspicuously stouter and 
heavier body spines interspersed 
through these clusters, about as shown 
in figure, but the arrangement appar¬ 
ently more or less variable; ovisac band 
fairly broad, made up of numerous 
spines, with a considerable number of 
disk pores scattered through the whole 
breadth of the band, but more numer¬ 
ous on the anterior and posterior mar¬ 
gins, indistinctly interrupted laterally 
and posteriorly "by narrow clear strips; 
Lower California, on Enceliapalmeri 
(Compositae) collected by G. F. Ferris, 
August, 1917 (paratype). There are no 
additional published records of its 
occurrence.
