Mitothrips megalops certainly belongs in a distinct genus, 

 for the third and fourth antennal segments are remarkably 

 elongated, the fourth alone being nearly three times as long 

 as the five succeeding segments combined. Furthermore, 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 above restricted, Franklinothrips contains two species 

 which may be separated by the following: 



Key to the Species of Franklinothrips. 



a. Antennae less slender, the third segment about n times as long 

 as greatest subapical width; segments 1-3 clear pale yellow; com- 

 bined lengths of segments 5-9 about 1.3 times as great as that of 

 segment 3 ; 3 about 2.5 times as long as 5. Fore wing near apex 

 with a rather poorly defined pale spot which does not attain the 

 ring vein. (Fla., Tex., Nicaragua, Panama.) 



P. vespiformis Crawford. 



aa. Antennae more slender, the third segment about 13 times as long 

 as greatest subapical width ; segments 1-4 clear pale yellow ; com- 

 bined lengths of segments 5-9 about equal to that of segment 

 3 ; 3 about 3.7 times as long as 5. Fore wing near apex with a 

 large distinct white area entirely occupying the space between 

 the two portions of the ring vein. (Panama.)
