Mitothrips megalops certainly belongs in m distinct genus, 

 for the third and fourth antennal segments are remaricably 

 elongated, the fourth alone being nearly three times as long 

 as the five succeeding segments combined. Furthemiore, the 

 head is greatly enlarged and not at all continuous in outline 

 with the prothorax, and the eyes are exceedingly large, promi- 

 nent, and reniform. It is doubtless the closest known relative 

 of Franklinothrips : the resemblance of the wings is especially 

 noteworthy. 



As atK>ve restricted, Franklinothrips cont.iins two species 

 which may be separated by the following :
