Appears to be allied to Listroderes subcmctus, Bohem., from Chili, with

Amathynetes, gen. nov. 



General characters of typical Listroderes (L. costirostris, Gylh.) ; losti'um

 sinuous and clavate at the apex ; funiculus seven-jointed, seccmd joint con- 

 siderably shorter than the first, the third to sixth joints small and globose, 

 the seventh joint very slightly longer and much wider ; the clul) rather
