REVISION OF CHALCID WASPS 



OF GENUS EURYTOMA 



IN AMERICA NORTH OF MEXICO 



By Robert E. Bugbee ^ 



The species of the genus Eurytoma lUiger, from America north of 

 Mexico, have never been treated in a taxonomic study. The first 

 species of the genus from the United States were described by Thomas 

 Say in 1836, probably from specimens taken somewhere in the state 

 of Indiana, but the type material is lost. Additional species were 

 described by Francis Walker (1843 and 1846), Asa Fitch (1859), and 

 Benjamin D. Walsh (1870). In 1881 William Ashmead published his 

 first descriptions of new species of Eurytoma and continued to do so 

 into the early 1900's. He was a most productive worker and in 1888 

 issued a revised generic table of the family Eurytomidae, designated 

 genotypes for all genera of the family in 1894, and in 1904 published 

 the comprehensive "Classification of the Chalcid Flies." These 

 works, however, consisted primarily of brief descriptions and keys to 

 the genera but did not include keys to the species. Although many 

 of the Ashmead species are recognized today on the basis of his type
