DANGEROUS PESTS.

Prof. Alex. Craw. chief of the En-
genealogical Division, presented the fol-
flowing interesting report:
| Since my last report dated March
| 15th / have to report the arrival of
| forty-four steamers and sailing vessels
into the port of Honolulu from out
| side the Territory bringing 1852 pack
ages of fruits and vegetables, forty
five cases and boxes of trees and plants
and eighty-three packages of plants
by mail.
| Again we have had occasion to de-
port infested fruit; sixty-six boxes of
lemons infected with certain insects
that we can do without and others that
! We believe it best not to introduce
| fresh stock. Several plants received
| from Florida by mail have been burned
up because they were infested with
new insects. A few plants of economic
! Importance were fumigated and after
wards carefully inspected without find
ing any living infection. Subsequent
examinations will be made of those
plants.
| Early in April a case of ten new
varieties of sugar cane for experiment
al purposes was received from Fiji.
The case and cane were Immediately
placed in one of our fumigating rooms
and treated with only sufficient hy-
drocyanic acid gas, to destroy any in
sects that may have developed in COM
ing through the tropics, and liable to
escape when the box was unpacked.
The following day each piece of cane
was carefully examined with the fol-
lowing result. One cane borer (beetle)
and two larvae of the same. One
piece of cane. from the appearance of
the injury, must have been infested
with the larva of a large moth. One
larva of a small Buprested beetle cut
ting Il tunnel transversely and slightly
under the surface of the cane. Twelve
bud worms" al.o a few adult and
larvae of mealy bugs (Dactylopius cal
ceolariae.) Samples of each insect were
preserved for office specimens. Twelve
orange trees completely covered with
''chaff scale (Parlatoria pergandeD al
so a liberal supply of the serious 'pur-
pie scale" Gepidosaphis beckiD came
from Florida and were burned. There
is great danger in our people ordering
trees or plants from Fla. or La. as the
destructive white fly (Aleyrodes ci-
trD is liable to be introduced. This
insect is closely related to scale insects.
but differs as the females as we'll as
the males, are winged. On account of
this destructive insect and IFS widely
spread existence in those states, no
plants were allowed to enter Califor-
MIA from there. The larvae of this pest
in its first stage resembles a small
scale. $50 grated orange trees from

infested with leaf-miners. Several YES
seis of the sugar fleet have come in this |
month in ballast from San Francisco
Upon inspection and before permission |
was granted to discharge the same, we
We're assured by the captain of each |
vessel that the ballast was obtained |
from Telegraph Hill. 1t consisted OF |

tains and ship agents to secure what |
necessary ballast they may required
from that hill. 1t also has an advan-
tage of being adjacent to the docks in |
San Francisco. The material mas been
used to fill in along the water front

structions as to how to accomplish the
best results with them.
WAR ON BEETLES.
Entomologist Kotinsky showed some
noculated Japanese beetles which are
'eady to be sent out to sections where
he beetle has been doing considerable
larm. The department will prepare
colonies of inoculated beetles for those

BELGIAN HARES
Mr.. Craw called attention to Belgian
lares. He had encountered some on
