This group is unknown to me in nature. It is based upon Thomson's genus 

 Colotrechnus, occurring in Sweden, who called it a subtribe. 



Thomson's description clearly indicates that it belongs to the family Cleonipnidic, 

 although the absence of mesonotal furrows is strongly suggestive of the Encijriidir. 



Wings with the stigmal and postinarginal veins very sliort, the knob of the former rounded, subses.sile ; 

 frontal depression long ; antennse 12-jointed, inserted below the middle of the face, the funicle .5-jointed ; 

 hind tibise compressed, the bind margin denticulate . . Colotreclinus Thomson (type C. subenerulens Thorns. ).

 This family was very fully characterized and discussed in my paper entitled 

 "On the Genera of the Subfamily Encyrtime," published in the Proceedings of the 

 U. S. National Museum for 1900. It is unnecessary, therefore, to repeat the charac- 

 terization of the group, since the classification here is practically identical, the only 

 change being the establishment of a new tribe in the Eupclmiinr, and some new 

 genera in the various tribes.
