ceived from the federal Bureau of Plant Industry and it is felt that the 
outlook for control is fairly hopeful in New Jersey. 
Other Imported Pests. At various times during the past few years 
weevils such as Acythopeus orchivora Blackb., Cholus cattleyce Champ., 
Cholus forhesii Pasc., Diorymellus Icevimargo Champ., and two species 
as yet undescribed have become established in New Jersey orchid 
houses where some of them have done considerable damage. Most 
of them are natives of tropical America and very little is known of 
their life-histories. As a result hand picking of the beetles or destruc¬ 
tion of badly infested parts is practiced. 
Another weevil, of European origin, however, which has been taken 
in New Jersey is Magdalis barbicornis Latr. According to.Blatchley 
& Leng (Rhyne, or Weevils of N. E. Amer.), this species has been 
taken also in New York and Massachusetts. In the recently issued 
government publication, “A Manual of Dangerous Insects Likely to 
be Introduced in the United States through Importation,” it is listed 
as a pest likely to be introduced in apple, quince and medlar trees and 
known as the apple-stem piercer. In the above publication which 
supplies a long felt need, hundreds of foreign insects are listed as likely 
to be introduced, principally on nursery stock. 
x Inasmuch as practically all of the nursery stock imported into New 
Jersey consists of ornamentals, it is interesting to note that 42 species 
are likely to be imported on alder, that 22 might come in on ash, 60 
on beech, 44 on birch, 19 on cedar, 28 on elm, 83 on oak, 16 on linden, 
14 on hawthorne, and 227 on various conifers, most of them belonging 
to the Coleoptera, Lepidoptera and Hemiptera. If importations 
continue as time goes on, it is not unlikely that we will eventually 
have all of them in New Jersey. 
IMPORTANT FOREIGN INSECT PESTS COLLECTED ON 
IMPORTED NURSERY STOCK IN 1917 
By E. R. Sasscer, Washington , D. C. 
In spite of the disturbed conditions in Europe during the fiscal year 
1917, the five principal European countries exporting nursery stock 
to the United States offered for entry some three million more plants 
than was the case in the fiscal year 1913, one year before the war. 
The following table indicates the amount of nursery stock received 
from these countries for the past five years. 
As the result of state and federal inspection, the following important 
insects have been intercepted on nursery stock during the calendar 
year: Egg masses of the gipsy moth ( Porthetria dispar Linn.) were
