1 place two species in thi.s genus. They may be separated by the 

 folloAving- characters: 



All femora dark T)rown; tibuie and tarsi ))right yellow nzell (p. 196). 



LegH gray-brown; tarsi somewhat lighter; fore tibia; yellowish. ..ywrr/aHz/r/ (p. 197). 



The female of the species uzeU comes within the definition of the 

 o-enus PhlcBothrips^ but the male of this species has the teeth at the 

 tip of the fore femora, which is the principal chamcter upon whicli 

 Uzel has separated his genus livantliothripH. This species, therefore, 

 appears to unite the characters of these two genera, and as more 

 emphasis is i)laced upon the description of the female than upon that 

 of the male, I have preferred to include this species in the established 

 genus Phla'otkrips rather than to erect a new genus for it.
