Thuya and Azalea from Japan, and on rose from Holland. Nests of 

 the brown-tail moth (Euproctis chrysorrhwa Linn.) were collected on 

 five consignments from France. Egg masses of the European tussock 

 moth (Notolophus antiqua Linn.) were repeatedly collected on stock 

 from France and Holland, and pupie of a dagger moth (Apatela auri- 

 coma Fab.) were reported on five shipments from France and one from 

 Holland. Gracilaria zachrysa Meyrick has been frequently reported 

 on azaleas from Holland, Belgium, and Japan. Porthesia similis 

 Fuessly, a close relative of the brown-tail moth, was collected on rose 

 in Georgia from Holland. The larvse of this moth are found in small 

 hibernaculse and may be easily overlooked. This insect has a wide 

 distribution in Europe, and has also been reported from China, Japan, 

 and Korea. The Leopard Moth {Zeuzera pyrina Linn.) was collected 

 in Ohio on Paradise apple stock from France. Dead larvae of the pink 

 boll worm (Gelechia gossypiella Saunders) were found in samples of 

 China cotton enclosed in glass trays exhibited at the Panama-Pacific 

 Exposition at San Francisco. Although every precaution was taken 

 to safeguard this material by the California authorities, the finding of 

 these dead larvae forcibly demonstrates the possibility of introducing 

 new and injurious pests in plant products exhibited at expositions. 



In this connection it is of peculiar interest to note that the prize 

 ship Appam, which was brought into Hampton Roads early in the 

 year, contained as a part of its cargo some two hundred tons of cotton 

 seed from Lagos, West Africa, a region known to harbor the pink boll 

 worm. Although no living larvae of the pink boll worm were located 

 it was apparent, from the condition of the material, that about 2 per 

 cent of the seed had at one time been infested with this insect. To 

 safeguard the cotton interests of this country the entire consignment 

 was converted into fertilizer by a Portsmouth firm, and the dock on 

 which the seed had been unloaded was thoroughly cleaned and the 

 ship fumigated with hydrocyanic-acid gas. The arrival of a quaran- 

 tined product on a prize ship opens up a new avenue of entrance, and
