AGROMYZID LEAF MINERS — FRICK 349 



lum. The mesonotum and its setae were later illustrated (Frick, 

 1956a). 



Because complete synonymies have been given previously (Hendel, 

 1931-1936; Frick, 1952, 1953a, 1956b, 1957a), only North American 

 synonyms for genera, subgenera, and species are listed herein. The 

 most recent paper (Frick, 1957a) gives all but two name changes 

 not previously pubhshed so that the correct binomina would be avail- 

 able for this synopsis. The two names not included are Liriomyza 

 reverberata (Malloch) and L. sorosis (Williston) ; the changes are dis- 

 cussed in full herein. 



The locations of those holotypes not mentioned in the original 

 descriptions or in other papers are given herein. A number of types 

 of Frost's species had been retained in his personal collection and these 

 he recently transferred to the U. S. National Museum. 



The references are limited to the original descriptions and to those 

 papers that have illustrations or good redescriptions of previously 

 poorly defined species. The citations are not intended to be complete 

 or to give all nomenclatural changes because those have been pre- 

 viously published (Frick, 1952, 1953a, 1957a). Those papers cited 

 in the text by author and date only are given in full in the list of 

 references cited (p. 445).
