In part, as follows:
The leaf.Hopper Of the Cane.
This small insect is highly injurious
to cane and its destructiveness threat
ems to exceed that of the cane-borer
beetle. Its habits appear TO be quite
identical with those of pest well
known in the canefelds of Java, but
whether the insects belong to the same
species is very doubtful. Specimens
of the Hawaiian insect have been sent
both to Washington and to England
for examination, but unless identical
with one OF the several cane-infesting
species, It is not very likely to be
known to scientists, since II belongs
to an obscure and unattractive group
Of insects very little collected or studi-
ed in tropical countries, where there
is usually an abundance of more snowy
creatures.

that country has several species), does
not appear to be native of that coun-
try but to have been imported from
ICelebes, and when the Hawaiian in
sect was accidentally imported is at
present unknown. II is OF the first i'm
portance TO find out the native country
of our species II II can be learned. for
unhappily II may be necessary to spe-
cially send in search of its natural enc
mics or parasites, and for this reason
specimens have been sent to those
most likely to be able to furnish in
formation on this point.
Even should this most desirable in
formation not be forthcoming, yet ma
tural enemies may yet be procured
Certain lady birds inhabiting Austria
1, liza, and no doubt other countries, are
known to prey on leaf-hoppers, and
some OF these are probably not parti-
cular as to the exact species OF leaf
hopper here present, or from some very
similar species, there is little chance
OF success, and for these parasites the
native home of the leaf-hopper must
be first discovered.
There Is at the present time one
enemy of the leaf-hopper, which Is OF
considerable Importance. This was
first found in the gardens in Honolulu
as rare insect, seven years ago. and
1t was no doubt accidentally imported
some few years before that time. II
would naturally take some time to in
crease from one or two accidentally in
troduced individuals to such numbers
as to become noticeable.
Next follows long description of
the group TO which the insect belongs,
its habit of attacking the lady bug,
the enemies OF the hopper such as the
spiders and earwigs, the places where
the hopper exists in the Islands, the
signs OF hopper attacks, the laying OF
eggs in the stem as well as the leaf,
etc. Prof. Perkins next takes up the
cane-borer, Japanese beetles, mole
cricket and caterpillar or pyralid
moth. The following list OF insects
more or less injurious to cane in the
Hawaiian Islands is given:
Beetles.
The cane-borer (Sphenopharus OBJ
scurus).
2. Long-horned BEETLE (Aegosoma re-
fiexum).
3. Small borer (Hypothenemus SD. J.
4. Nitidulid beetle (Haptoucuc sp).
8. japanese beetle (Adoretus mmbro-
sis).
caterpiIIars.
Omiodes acaepta and probably the y
very closely allied species.
2 o, epicentra.
g. The "peelua" (Spodoptera manri-
yia).
