IPLANTS LIKELY TO BE ATTACKED
BY THE INSECT.
1 AS Mr. Green informs us, these are of
! the order of Acanthaceae, Rubiaceae and
/ Verbenaceae. From India we learn that
| Ternstroe miaceae is included. to which
belong the Camellia, the common tea
| plant, and also the Solanaceae.
| Amongst the Rubiaceae the Hawaiian
flora is very rich, chiefly in shrubs and
trees, some of these important forest
plants. Hillebrand records sixteen spe-
cies of Kadua, shrubs of various sizes in
our forests. Five species of Goulda,
shrubs and small trees. Two species of
lGardenia, several of these are In cult
vation., Bobea, five species of forest
| trees. Plectronia, shrub. Coffee both
| the Arabian and Liberian coffee trees.
Morinda two species, third recently
| introduced from Fiji Straussia, five spe-
cies of important forest trees. Psyche
tria. two trees. Paederia Foetida, this is
| the tall woody climber overrunning trees
and shrubs in the mountains near Homo
| lulu Nertera, one species. Coprosm9,
nine species of shrubs and small trees.

tai plants of this order. as those hand
some shrubs, the Ixora. Pavetta, Bou-
wardia, Musaenda, Pendas, Carnea,. Ser
| issa Foetida. and others.
| Under the Verbenaceae come a large
number of troublesome weeds, such as
| verbena Bonariensis V. Officinalis;
Priva Aspera; Stachytarpheta Dich-
otoma; Lantana Camara; Vitex Tri-
folia growing SO abundantly on
| k,yI1,
yet. the blight could not be found upon
the same); and the various species of
| C1erodendron, of these c. Fragrans has
spread up in all the valleys near Homo
lulu
| To the order of Ternstroemiaeeae be-
longs the Tea-pIant. Camellia. and a
small tree. spread over all the Islands;
this is Eurya Sandwicensis.
The Tomato, Lycapersicum Esculen-
tum, and the Red Pepper, various spe-
cies of Capsicum are mentioned as food
plants of the Lantana blight. These are
| included in the large order of Solanaceae
| to which belongs the Potato and Egg
| plant in several varieties. OF Solanum
We have some ten species of shrubs and
1 trees growing on the Islands. Notho-
I cestrum is represented in four species of
| forest trees. Lycium Sandwicense fur
nishes us with a fruit Rhysalis Peru
yiana is the common Cape Gooseberry.
| Nicandra Physaloides, Datura Stramo-
mum. very common weed. The Flori-
| poncio. The Nicotiana Glauca. and N.
Tabacum, are all liable to be attacked.
Beside these, quite a lot of ornamental
garden plants belong to this order.
! OTHER SPECIES OF oRTHEZIA
KNOWN TO ME AND ENEMIES
| FOUND UPON THE SAME.
! So far, sixteen species of Orthezia are
recorded, and some of these will prove
Synonymous. In my travels and study
/ of the Coccidae and their enemies, L
have had no occasion to search for en-
emies of this blight, as none We're pres
ent upon our Island previous to the ap-
pearance of o. Insignis.
| During 1891 several specimens of these
scales were found on Solidago, in Ore
! gon No enemies Observed. This is like
| ly O. Americana of Canada and the
United States. A very large and hand
some form was found on roots of Yucca,
at Taluca Mexico, Aug. IL, 1897, and
| later on roots of various other shrubs
and plants No enemies observed. About
the same time, at the foot of Popocate-
petl, Mexico. a small Ortheza was found
| to infest a species Of Baccharis, the in
sects being very abundant, especially in
| its early stage. AS far as | can remem-
| Der, this is not unlike our species. /
/ found no parasites in box on mounting
! them November 1891 At Oaxaca, Mex
| leo, Aug. 20. 1897 upon garden plants I'M
known to me. an Orthezia was found
numerous. Specimens saved in pill
| boxes had produced no parasites on Nov.
%, 1897, but four pupae of a Scymnid
| CHyperaspis) We're found present and
| dead
| During the latter part of June 1885,
at Nikko, Japan, upon species of Arte
misa, an Orthezia was found, which was
somewhat larger than our species A
few specimens were saved in pll-boxes
| pts was bred, and according to Mr..
Schwartz, it proved to be new to Japan,
where but one species had been recorded
veloped within the egg sacks of the scale.
| 1t is closely related, IL not the same TO
the European H. Reppensis
ENEMIES OF THE INSECT.
Aside from the small Ladybrds Ciy-
peraspis) above mentioned no parasites
are known to me as preying upon this
peculiar scale-insect. While in Ceylon
during the beginning of 1895, l expressed
myself as to the possibility of Cryrtolae-
mus Montrouzieri feeding upon TINS
blight and Mr.. Green has made an at
tempt of introducing the same. The in
sect has now been observed amongst, ana
close to, the OrtheZia upon Lantana, YET
to all appearances 1t is seen to be feed
ing upon mealy- bugs Oacylopius). 1t is
still likely that in time this yoracfous
