The species is named in appreciation of the opportunity of 

 Avorking for a time at the South African ^Museum and the 

 kindly assistance afforded me by the director, Dr. L. Peringuey, 

 whose comprehensive studies of South African entomology 

 have made known many and interesting Coleoptera and Hymen- 

 optera of South Africa and thrown much light on the biogeog- 

 raphy of Africa, and whose administration has rendered the 

 South African Museum one of the best of provincial museums.
