with Aleuroparadoxus punctatus Q. and B., and citrus foliage from 
Cuba was on four occasions infested with Dialeurodes citrifolii (Morg.). 
Aleurothrixus floccosus (Maskell) was intercepted on Citrus sp. from 
Porto Rico. 
The Sweet Potato Weevil, Cylas formicarius (Fab.), was taken on 
sweet potatoes on 16 occassions—from China 5, Cuba 5, Nassau, 
Bahama Islands 4, and Haiti 2. The West Indian Sweet Potato 
Weevil, Euscepes batatae Waterhouse, was also taken in sweet potatoes 
which arrived from Brazil, Trinidad, and twice from Barbados. 
Soil which arrived with plants in passengers’ baggage was found on 
two occasions to be infested with larvae of Agriotes lineatus L., from 
Finland and Switzerland, and an unrecognized species of Agriotes was 
found in sand used as packing around dahlia roots from England, as 
well as a species of Limonius in soil about the roots of Scotch heather 
also from England. 
The European Earwig, Forficula auricularia L., which in recent 
years has caused a considerable amount of injury in Seattle, Washing¬ 
ton, was discovered in two miscellaneous shipments of bulbs arriving 
from Holland. It has been felt for many years that this insect gained 
entry into this country in soil, and in fact, there are instances on record 
that it can be, and is, carried by soil; however, this appears to be the 
first record of its arrival with bulbs. 
Cocos nucifera from Cuba has been found to be infested with the 
following Thrips: Franklinothrips vespiformis (Crawford), Haplotkrips 
merrilli Watson (4), and Symphothrips punctatus Hood and Williams; 
and bananas from Roatan, Honduras were infested with Metamasius 
sp. The Tahiti Coconut Weevil, Diocalandra taitensis (Guer.), has also 
been collected from the former host from Hawaii. Fibre plants from 
Columbia, arriving in Washington, D. C. were found to carry the 
workers of Nasutitermes sp., a genus which does not occur in the United 
States, and is considered a destructive wood borer and injurious to 
plants. 
Two large shipments of broom corn arriving from Hungary during 
the year were found to carry a large number of living larvae of the 
European Corn Borer, Pyrausta nubilalis Hnbn. As a condition of 
entry, this corn was carefully sterilized with live steam, preceded by a 
vacuum. 
Had it not been for the vigilance on the part of an inspector of the 
Federal Horticultural Board, located at Baltimore, Maryland, it is 
possible that the Pink Bollworm, Pectinophora gossypiella Saund., would
