The species here described corresponds in almost every respect to 

 the rhysopvs nllcis Haliday, as described by Uzel in his Monographic 

 der Ordnung Thysanoptera, page 115. The genus name Physopux 

 has since been changed to EutJirqjs b}' Hinds in his Monograph of the 

 Thysanoptera of North America. I therefore have called this species 

 EatJirips ullci)^ cnliforniciis. The Physojius uJicis of Uzel is recorded 

 as found in England (Haliday), in Finland (Renter), and in Bohemia 

 (Uzel).
