INCOMPLETELY DETERMINED PESTS 
Each year interceptions include some pests which appear to be new to science 
and hence undescribed. Others are not determinable because available descrip- 
tions are inadequate and authentic material is lacking. In many cases the 
intercepted material is inadequate or not in a stage to permit determination. 
INSECTS 
Among the incompletely determined insects intercepted during the year were 
the following fruitflies: Anastrepha sp., probably fratercidus, intercepted at 
Baltimore, Brownsville, New Orleans, New York, and Philadelphia in peach, 
grapefruit, and orange from Argentina, Brazil, Mexico, and Trinidad; Anastrepha 
sp. at Jacksonville, Laredo, Miami, and New Orleans in cherimoya, guava, mango, 
orange, plum, and quince from Brazil, Colombia, Honduras, Jamaica, and Mexico; 
Ceratilis sp., likely capitata, at Seattle in coffee berry from Hawaii; Ceratitis sp. at 
Boston in orange from the Union of South Africa; Dacus sp. at Baltimore in 
orange from Mozambique; Epochra sp., probably canadensis, at El Paso in currant 
from Mexico; Rhagoletis sp., probably pomonella, at Brownsville and Laredo in 
apple, Crataegus sp., mango and plum from Mexico; and Rhagoletis sp., probably 
suavis (Loewj, at Nogales in black walnut from Mexico. 
In addition to the incompletely identified fruitflies the following miscellaneous 
insects of special interest were intercepted: Acrolophus sp., near pallid 'us (Mosch.) 
(Acrolophidae), at Hoboken with orchids from Colombia and Costa Rica; Agro- 
myza sp., near setosa Loew (Agromyzidae), at Nogales in purslane from Mexico;
