the number reported for Lncn ase tx Ing due to Larger numbers of Inter- 
ceptions by the Division i C Foreign riant Quarantines referred to the Division

material were Involved. Ar the end of the fiscal year work on nearly • 
remained unfinished. Owing t-» the volume of Identification work, only a 
small amount of time remained available for the numerous research problems In 
classification of insects thai require solution before more complete and 
accurate identifications will be possible in many groups. Nevertheless, various 
relatively minor bul Importanl research undertakings in classification have been 
conducted, and a number of new species have been described for which names 
bave been urgently Deeded in economic or biological studies conducted by this 
bureau and other agencies or individuals. In addition, certain studies in 
morphology, which have a direcl bearing on classification and identifical 
ts, have been completed and others undertaken. Thirty-four papers, | 
sh< rt. reporting the results of taxonomic and morphological studies, or describing 
new species, have been published during the year. 
FOREIGN PARASITE INTRODUCTION 
During the year particular attention was given to the importation of natural 
enemies of the oriental fruit moth, the pine shoot moth, the larch casebearer, 
and the alfalfa weevil. Also la rue-scale importations of fruitlly parasites were 
made into Hawaii under special funds provided for this purpose and into Puerto 
Rico against the sugarcane borer and other pests. With few exceptions, im- 
portations were made in the adult stage, thus eliminating any risk which might 
he involved in bringing living hosl material into the United States. 
The principal hosts Of the parasites imported into the continental United 
States and the countries in which the material was obtained are as follows:
