collected on three occasions, once from Belgium and twice from France, 
hosts not given, and one nest of the brown-tail moth ( Euproctis chry- 
sorrhoca Linn.) was taken on apple from France. Larvae of the swan 
or gold-tail moth ( Porthesia similis Fuessl) have been found on rhodo¬ 
dendron, laburnum, and roses from Holland. According to European 
writers, this insect is a general defoliator of forest trees, and, such 
being the case, every effort should be made to prevent its establish¬ 
ment in the States. 
Nests of the fruit tree pierid ( Aporia cratcegi L.) have been located 
in six shipments of deciduous fruit tree seedlings from France. The 
larva of this insect is a general feeder and is recorded as injuring the 
foliage of fruit trees, wild rosaceous plants, and oak trees. 
Larvae of the sorrel cutworm ( Acronycta rumicis L.) have been col¬ 
lected on four occasions, twice on rose stock and once on Cornus from 
France, and once on azalea from Belgium. It is difficult to predict 
how serious a pest this would develop into if established in this country. 
In Europe it feeds on the foliage of strawberries, hops, and various 
shrubs and trees. The bay psyllid ( Trioza alacris Flor.) was reported 
on a shipment of Belgian bays, and the box psyllid ( Psylla buxi Linn.) 
and the box leaf miner (Monarthropalpus buxi Lab.) have been col¬ 
lected on boxwood from Holland. As in previous years, egg masses 
of the European tussock moth ( Notolophus antiqua Linn.) and pupse 
of the dagger moth ( Apatela auricoma Fab.) have been repeatedly 
taken on miscellaneous French and Holland stock. What appears to 
be the cocoons of a sawfly ( Emphytus cinctus Linn.) have been col¬ 
lected on four shipments of roses from England. 
Ninety pounds of seed of Prunus sargentii from Japan, received in 
Washington, were found to be slightly infested with Anthonomus bis- 
ignatus Boel., which, judging from the condition of infested seed, is a 
very unwelcome guest. This shipment was fumigated in vacuum 
with carbon bisulphid at the rate of 3 lbs. per 1000 cu. ft. with an expo¬ 
sure of 24 hours. As an additional safeguard, the entire shipment 
was stratified in boxes covered top and bottom with a 24 mesh per 
inch wire screen. One of the chaff scales ( Parlatoria chinensis Mar- 
latt) was taken on Pyrus sinensis and P. ussuriensis from China. The
