RHYNCHOPHORUS SWIERSTRAE. 153 



I have dedicated this species, which belongs to Chevro- 

 lat's genus Omotemnus ^), to the late K. N. Swierstra , the 

 well-kwown Conservator of the Entomological Collections 

 of the Zoological Garden at Amsterdam, who died on 

 April 18th, aged 50 years. 



Rhynchophorus Swierstrae is a narrower species than Rh. 

 serrirostris but especially distinct from it by the waved 

 and keeled rostrum , by the much less transverse antennal 

 club, by the more convex prouotum and its otherwise 

 shaped basal lobe, by the keeled anterior femora, etc.
