Genus Plegmapterus M. Fern. 



This genus is undoubtedly very closely related to 

 Ewyphynms, from which it differs only by the obliterate 

 keels of the pronotum; the male of its single species is, 

 however, unknown and it prevents me from defining its 

 relationship more precisely.

The type of Walker's C. saturatus agrees with the 

 description of P. ferruginosus St;U drawn by M. Fernandez 

 from Stal's co-type, and there is no doubt that C. irisus 

 Serv. is also conspecific with both.
