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: Anastrcpha 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, Jam.aiea, and Mexico; 
Ceratilis sp., likely capitata, at Seattle in coffee berry from Hawaii; Ceratitis sp, at 
Boston in orange from the L'nion of South Africa; Dacus sp. at Baltimore in 
orange from Mozambique; Epochra sp., probably canadensis, at El Paso in currant

apple, Crataegus sp., mango and plum from Mexico; and Rhagoletis sp., probably 
suavis (Lcew), at Nogales in black walnut from IMexico. 
In addition to the incompletely identified fruitflies the following miscellaneous^
