Gemis Kakotlnips Williams 1J)N. 



Characterised as follows: — antennae eight segmented, maxillary palps three 

 segmented. Labial palps two segmented. Ocellar spines between the posterior 

 ocelli. Fore vein of the front wing set regularly throughout its whole length with 

 spines. Short lateral lyrocesses on each side of the eighth abdominal segment in the 

 male, curving hackimrds and upwards ; rudimentary hut distinguishable in the female. 

 Larva with 9th and 10th abdominal segments dark coloured. 



Type A', robustus (Uzel 1895). 



The characters in itahcs distinguish it from the genus FranUiniella^ 

 Karny, to which it is closely allied.

^ Uzel's Physapus ( = Euthrips Hinds) was split up by Karny (1907) into five genera, 

 one of which was Physapus. This name being already occupied it was changed (Karny 

 1910) to Frankliuiflla, The typo of this latter genus is F. intonsa Trybom ( =F. vulgatis- 

 simus Uzel).
