spines along this margin and, along the 
anterior margin of the band, in a simi¬ 
lar pore row, averaging about 3 to 5 
deep, and definitely intermingled with 
the spines making up the band along 
this margin;

posteriorly, 
inclosing 4 
distinctly 
separated 
transverse 
bands of 
scattered 
spines, these 
extending to 
the ovisac 
band on each 
side, the 
anterior 2 
about 3 or 4 
spines wide, 
the poste¬ 
rior 2 narrower, the last composed 
mostly of only a single row of spines; 
anal ring oval, characteristic for the 
genus, the pore bands on each 
half slightly separated at 
their ends and the inner 
margin of the same distinctly 
and acutely angulate ante¬ 
riorly and posteriorly; with 
the usual 6 anal ring setae, 
these rather long and 
slender. 
Material from the follow¬ 
ing localities has been more 
or less carefully examined 
during the preparation of the 
preceding description: Bar¬ 
bados, Bolivia, Brazil, British 
Guiana, Canal Zone, Ecua¬ 
dor, Grenada, Panama, St. 
Croix (Virgin Islands), and 
Trinidad. Published distri¬ 
bution records add Antigua, 
Dominica, Jamaica, and St. 
Kitts to the above list. 
The host records, both for 
material examined and from 
published information, in¬ 
clude : Capsicum (Solana- 
ceae), Carica (Passiflorae), 
Citrus (Rutaceae), Cocoloba fig. 29. 
(Polygonaceae), Codiaeum 
(Euphorbiaceae), C o f f e a 
(Rubiaceae), Euphorbia (Euphorbia¬ 
ceae), Gossypium (Malaceae), Haem- 
atoxylon (Leguminosae), Hyptis (Labi- 
atae), Lonicera (Caprifoliaceae), Lor- 
anthus (Loranthaceae), Malphigia 
(Malphigiaceae), Parderia (Rubiaceae), 
Rosa (Rosaceae), Saccharum (Grami- 
neae), Sanchezia (Acanthaceae), and 
Sapium (Euphorbiaceae). 
ORTHEZIA PSEUDOGRAMINIS, NEW 
SPECIES 
Figs. 3, U, and 29; PI. 2, C 
Adult female. —External appear¬ 
ance in general resembling that of 
graminis very closely, differing princi¬ 
pally in the following details: Dorsal 
bare strip on each half of the body nor¬ 
mally extending only over about the 
anterior half of the body length, the 
remainder of this area covered with secre¬ 
tion, although not with prominent erect 
plates; marginal fingerlike tufts of 
secretion along the posterior portion of 
the body somewhat longer than in 
graminis; ovisac averaging not more 
than two-thirds of the maximum 
length of that of graminis in specimens 
examined; shape of body, as mounted, 
much as in graminis, size averaging 
slightly smaller; relative. lengths of 
antennal segments approximately the 
same; legs somewhat stouter than in 
graminis; tarsal claw with denticles; 
dorsal and marginal spine clusters in 
general corresponding to those of gra- 
Orthezia pseudograminis: Adult female, dorsal and ventral; 
X about 31 
minis, but with the dorsal abdominal 
clusters forming complete bands ex¬ 
tending to the corresponding marginal 
clusters and separated from the same 
only by a narrow clear area, and with 
the two posterior dorsal thoracic 
clusters united with the corresponding 
marginal clusters by a very narrow 
band of scattered spines.
