ing citrus plants. Mr. Takahashi’s employment was brief, and he was 
unfortunately situated at a great distance from the orange-growing 
region. He secured, however, several interesting scale insects, which 
are described by Professor Cockerell in the coneluding article of the 
series. Of the injurious insects of Japan other than scale insects we 
should have a more explicit knowledge. We already know of the 
existence there of a larva affecting the peach, an account of which was 
given in Insect Life (vol. 11, pp. 64-66), which would be a most unde- 
sirable importation. We also know that the Japanese gypsy moth, 
Ocneria japonica, if accidentally introduced into this country, might 
prove as serious a pest as the Huropean gypsy moth has shown itself 
to be in Massachusetts. But with other injurious insects of this and 
other orders we are more or less unfamiliar. Further investigations in 
this line are, therefore, very much to be desired. 
In 1895 a large collection of unnamed Japanese insects of different 
orders was exhibited at the Chicago Exposition by Dr. K. Mitsukuri, 
of the Imperial University, Tokyo, Japan. This collection was depos- 
ited in the U.S. National Museum at Washington, and is now being 
named by specialists in different orders. Many of the insects are 
undoubtedly injurious, but we have no notes of their exact habits. 
Quite recently a small lot of Japanese insects was sent to the writer by 
Mr. M. Matsumura, of the Sapporo Agricultural College, who is taking 
up economic entomology, and as these specimens were accompanied by 
notes as to food plants the sending was an exceptionally interesting 
one. Among them the following are of especial interest: 
Spilodes kodzukalis Holland MS.; very injurious as a stalk borer to 
grasses, 
A species of Ancylolomia very like our Chilo oryzwellus; very inju- 
rious to rice stalks as a borer. 
Rhodophea hollandella Ragonot; rolling the leaves of pear. 
Nephopteryx rubrizonella; boring into the fruit of pear. 
Cacecia rosaceana Harris; rolling leaves of apple. (This species 
occurs abundantly in this country.) 
Hyponomeuta sp.; eating the leaves of apple and pear. 
Orgyia gonostigma (a common European species); eating the leaves 
of apple and pear. 
Laverna? sp.; very injurious to apple, working in the fruit like the 
codling moth and spinning its cocoon in the earth. 
YVrartema ? sp.; an injurious bud moth of the mulberry tree. 
Tinea sp.; near granella; attacking stored rice. 
Myelois sp.; attacking stored grain. 
Bombyx mandarinus Moore (the species which is believed to be the 
wild form of the silkworm of commerce); eating the Jeaves of the mul- 
berry tree. 
Stenobothrus bicolor Charp. (2); a grasshopper which is very injurious 
to vegetation in general.
