develope that of the Myinidse and Trichograramidas ; some of these 

 latter vie with the Mymaridas and the Teleadidas in the excessive 

 minuteness of their size. Many of the species of Encyrtidas have 

 been elaborated by Dalman, and Foerster has distributed them into 

 genera, and his Synopsis of these genera is here translated.
