Among the large series of Brenthids with which Dr. K. Jordan of the Hon. W. Rothschild’s Museum at Tring kindly entrusted me for examination, I found several species of Rhaphidorrhynchus Schoenh. recently described by me from the collection of the Brussels Museum and my own, and two species which I believe to be new to science. But special mention may be made of a new Arrhenodinae-genus which I propose to call Phymechus. Ubanius and Tmetogonus are two new genera of the same subfamily, of which I have added here the description: all may be considered as representative forms of the oriental group Orychodi in neotropical regions.
