certainly see that plants imported By
their officials are properly freed from
pests ana disease before being propa-
gated and distributed broadcast over
the country.
IL sou'e OF the plant-ioving citizens
OF this Territory would patronlze our
local nurseries and norist establish
ments. or consult them regarding GER
tain plants they intended ordering from
Florida and other states. II would save
them the modification OF finding out
that they had purchased such plants
as that miserable imported pest OF our
hillsides and pasture lands 'Kolu"
acacia farnesana). the white plu-
maria CPlumaria alba) so common on
the islands that lords OF wood suita-
bic for cuttings can be had Even
such well known old trees as the "Ka-
mani' IL brought in under its botan-
ical title Calophyllum inophyllum,
seeds of which can be obtained here
in abundance. Such cases can be liken-
ed to shipping GOALS TO Newcastle"
and since my residence here this has
frequently occurred. even with plants
as cheap and as common as the fore
going. but the above cases occurred
but recently and are fresh I'm my mind.
On September 1st a wardian case of
plants arrived from Singapore via
Honkong. The diving plants consist
ed of tD 'Mangosteens" (Garcinia
mangostena), QD Hevea brazilliensis
a rubber of Brazil and (5) trees of the
true nutmeg" (Myristica fragrans).
The plants were not in very good con-
dition after their long voyage. found
few specimens of Lepidosaphes pail
dae and fumigated all the plants and
the soil in which they were plunged
in the case-we dumped overheard in
to the salt water after having looked
IL over FOR larvae, or beetles. finding
nothing but a few living slugs and
worms.
Last summer DIR. N. Russell of Noun
tain View, Hawaii, went on a visit to
Japan. AS his citrus trees are much
infested with the purple scale" and
| he expressed desire to Investigate
parasites and predaceous insects of
that pest while there l gave him let
tiers of introduction to two of the
leading entomologists of that country.
On the Sth of August I received a
package of beneficial insects from DIR.
Russell consisting of three living beetles
ana five pupae of the "Asiatic lady
pird' (Chilocorus simils). These were
turned over to Mr. Kotinsky who has
succeeded In breeding a new genera
ton or this beneficial beetle. They
| nave gone through a complete cycle
In about thirty-five days, much short
er period than what he found II took
IN the Department OF Agriculture at
Washington, D. c., with the same
beetle. Colonies of this beneficial in
sect Will be liberated on various nor
tons of the Territory. DR.. Russell also
sent samples of Pulvinaria psidii that
nad been destroyed by fungus. Speci-
mems nave been sent to coffee planta-
lions where this scale can be found,
although 1t is nowhere on the island
round In numbers owing to being prey
ed upon by the larvae of the "mealy
Dug lady-bird" Crytolaemus montrou-
zieri. He also sent a few twigs in
rested with Aulacaspis pentagona,
Iarg., for food for the lady-birds.
from this material Mr.. Kotlnsky bred
number of internal parasites: Aphe-
mus fuscipennis, Howard; Aspidioto-
phagus citiinus. Craw; also two unde
termined species, all of which were
liberated upon scale insects. The two
determined species are already found
mere and are the principle insects that
prevent the Increase and spread of the
san Jose scale" on the islands

IL. M Ehrhorn, First Deputy Commits
sioner of Horticulture of California n
colony of the South African av'.
(Scutellista cyanea). This is the IN
ternal parasite of the black scale in
PRODUCED into California In the fall Of
lsol. through the kindness of Prof.
u Lounsbury, Government Entomol-
osist, cape Town, I received four liv-
ing females. the progeny of which has
accomplished wonders in suppresslne
that dirty scale in California We have
very few of the same black scale
(Saissetia oleae), but have another that
is closely allied thereto (Saissetia
nigra) upon which we liberated on Au-
gust 3Oth portion of the colony we
received from Mr.. Ehrhorn. On SEN
TENDER 29th we had the first to issue
mus completing their cycle in thirty
Gays, whereas In California It took from
forty to forty-seven days to complete
cycle. Two small colonies were lib
Grated In two places-out of DOORS
at the same time as those that were
bred in confinement.
On his return from Queensland last
April Prof. Koebele requested me to
SEND parasites of the red wax scale"
ceroplastes rubens to the Acclimatiza-
ton Society in Brisbane. AS that scale
could not be found at the time unless
In small numbers we could not compIv
with the request. On June 2Sth. the
Rev. Dr. Frackleton arrived on his wuv
