characterized subfamilies—Orothripine, Melanothripine, and Molo-

Arabian the families Heterothripide, Thripide, Ceratothripide, 
Merothripide, and Pancheetothripide. 
} This character is constant throughout the whole of the Thysano- 
ptera, breaking down only when we get to Urothrips, Bagn., and allies 
(Urothripoidea). It hence became an important character in my 
diagnosis of the suborder Polystigmata (= Urothripoidea).
