had not the customs officials at Norfolk been familiar with the cotton

The mango weevil {Sternochetus mangijerce (Fab.) ),Cryptorhynchus, 

 was collected in mango seed from Siam and Japan, and larvae of what 

 appears to be a new species of Conotrachelus were collected in avocado 

 seed from Guatemala. Primus seed from Japan received in Washing- 

 ton exhibited injury made by a species of Anthonomus closely related 

 to druparium. Several dead adults and larvae were taken. A pine 

 prop used to support nursery stock in a container was found to exhibit 

 galleries made b}^ Toviicus piniperda Linn., one of the more destructive 

 insect enemies of the pine in Europe. When received, many adults 

 had emerged, and it is impossible to say whether they emerged before 

 leaving Holland or after arriving in the States. Cocoons of a sawfly, 

 Emphytus cinctus Linn., were intercepted on green ash cross sticks or 

 props from England and on Manetti stock from France. Orchids 

 from Venezuela and Colombia were frequently found to be infested 

 with Tenthecoris hicolor (Scott). Lachnus fasciatus Burm. was col- 

 lected on Picea glauca from France, and Lachnus hyalinus Koch was 

 collected on Picea excelsa from France. An unrecognized species of 

 Lachnus was collected on Juniperus virginiana from France. The box 

 psyllid (Psylla buxi Linn.) was reported on thirty-three shipments of 

 boxwood from Holland, and a white fly, Aleurothrixus sp., was taken 

 on "Semilla de Molle" from Chile. Coccids have been reported on
