PROCEEDINGS OF THE UNITED STATES NATIONAL MUSEUM issued SMITHSONIAN INSTITUTION U. S. NATIONAL MUSEUM VoL 108 Waihington : 1959 No. 3407 SYNOPSIS OF THE SPECIES OF AGROMYZID LEAF MINERS DESCRIBED FROM NORTH AMERICA ' By Kenneth E. Frick ^ Introduction A total of 206 described North Ajnerican species are dealt with in this paper. All are separated by illustrated keys and briefly character-ized in short descriptions that include the known larval host plants and distributions. Although I am aware of some undescribed species in each of the large genera, I have attempted to define and illustrate each of the previously described species so that new species can be recognized as distinct. The objective of this paper is to lay a firm foundation upon which students of the agromyzid leaf miners may build. Originally only Nearctic species were to be considered. However, the types of the described West Indian and Central American species are in North American museums except for a few deposited in the British Museum (Natural History). Therefore, it was considered desirable to include the Neotropical area of North America not only because the types were available but because of the number of requests received by U. S. National Museum (USNM) personnel for identifica-tions of leaf miners from the southern extremities of North America. > Scientific Paper No. 1639, Washington Agricultural Experiment Stations, Pullman, Wash.; Project No 1260.
