In all, Ashmead described 41 genera of Tenthredinoidea. Of these 

 41 genera, 17 have been determined to be synonyms of older genera 

 and 5 have later genera for synonyms. Some of the segregates of 

 Perga defined by Ashmead will be classed as synonyms of the segre- 

 gates formed by Shipp. These will be discussed in a later paper.
