This species has been redescribed 
from material from France, Prussia, 
and Askhabad, Transcaspia, Central 
Asia. The published distribution 
records include Algeria, Austria, Bo¬ 
hemia, Corfu, England, France, Ger¬ 
many, Greece, Italy, Moravia, and 
Tyrol. 
The synonyms listed for this species, 
excepting two only, have been accepted 
on the basis of published references, 
mostly in European literature. The 
writer has had an opportunity to ex¬ 
amine specimens of an Orthezia col¬ 
lected by Prof. T. D. A. Cockerell at 
Tsuruga, Japan, on Medicago denti - 
cidata (Leguminosae) which appear to 
agree entirely with Kuwana’s descrip¬ 
tion of Orthezia japonica , and which it 
has not been possible to separate from 
0 . urticae, all of the presumably im¬ 
portant characters agreeing very closely 
with those of European specimens of 
that species available for comparison. 
Through the great kindness of Dr. F. 
Silvestri the writer has also been able 
to examine a single adult female from 
the type material of Orthezia martelli 
Leon., with the result that this species 
is, in his opinion, identical with 0 . 
urticae . It should be noted, however, 
that this conclusion has been based on 
the examination of a single decidedly 
imperfect specimen. 
The known host records include 
Achillea (Compositae), Aegopodium 
(Umbelliferae), Artemisia (Compo¬ 
sitae), Aster (Compositae), Ballota 
(Labiatae), Caltha (Rananculaceae), 
Centaurea (Compositae), Compositae,

volvulaceae), Erica (Ericaceae), Eu¬ 
phorbia (Euphorbiaceae), Galium 
(Rubiaceae), Geranium (Geraniaceae), 
Glaux (Primulaceae), Glecoma (Labi¬ 
atae), Gramineae, Hedera (Araliaceae), 
Heracleum (Umbelliferae), Hieraceum

lariaceae), Melittis (Labiatae), Ono- 
brychis (Leguminosae), Parietaria, 
(Urticaceae) Phlomis (Labiatae), Rubus 
(Rosaceae), Stellaria (Caryophyl- 
laceae), Symphytum (Boraginaceae),

Through the courtesy of Dr. F. 
Silvestri the writer has been permitted 
to examine a single specimen from the 
type material of this species. The 
condition of the microscopic mount pre¬ 
pared from this specimen is such that 
no satisfactory outline drawing showing 
the position and relation of the body 
structures can be prepared. However, 
it can be determined that the species is 
extremely closely related to 0 . ultima 
Cockerell, differing positively, so far 
as the writer has observed, only in that 
the anterior median section of the 
ovisac band has disk pores distributed 
through the inner two-thirds of its 
width, in that there is not an evident 
single row of disk pores along the an¬ 
terior margin of the band, and in that, 
in this section at least, the row of disk 
pores along the 
inner or posterior 
margin is not 
more than two 
deep while it is as 
much as three 
or four deep in 
idtima. It seems 
possible that the 
examination of 
additional and 
better material of 
both species 
may demonstrate 
that they are 
identical. As nearly as can be de¬ 
termined, the arrangement of the 
spine clusters and bands is practically 
identical with that found in ultima , 
and it is necessary to remark par¬ 
ticularly on the fact that these, as 
shown in Leonardi’s drawing of the 
denuded adult female, are very 
incomplete and inaccurate. The 
species was described from Cacheuta, 
Argentine Republic, collected on Alri- 
plex lampa (Chenopodiaceae).

An extended description of this 
species, accompanied by a number of 
figures, appeared in the above publi¬ 
cation, the edition of which was almost 
totally destroyed by the Japanese 
earthquake of September, 1923. From 
the description it appears to the pres¬ 
ent writer that this species, on com¬ 
parative study, may prove to have 
been based on nothing more than 
small-sized or somewhat stunted adults 
of 0. urticae. It has not been possible 
to include it in the key. The species
