550 Mr. Westw'OOd's Descriptions of some new Species q/'Diopsis. 



whilst the discovery of species at the Cape of Good Hope and Arabia will be 

 deemed \ery interesting, considering that hitherto the western coast of Tro- 

 pical Africa and the East Indies have alone supplied the species already de- 

 scribed. 



In conclusion, I must beg leave to express my thanks to Messrs. Wiede- 

 mann of Kiel, Klug of Berlin, and Goldfuss of Bonn, for the kindness and 

 lilierality with which they permitted me to make the most unbounded use of 

 the celebrated cabinets over which, with so much honour to themselves and 

 such advantage to science, they preside ; and also to M. Westermann of 

 Copenhagen, who has been so kind as to send me specimens of several species 

 of this very rare genus.
