156 December, 



in form. It also bears some slight resemblance to Ugyops Kinbergi, 

 Stal (Eugenies Besa, 274, 156, tab. iv, fig. 2), but the crown and 

 antenna} are much too long, and the keels on the face entirely dis- 

 similar ; the hinder tibiae alone bearing spines, as in this new genus. 

 I have much pleasure in naming the genus after Dr. C. Berg, for 

 his kindness in forwarding to me his specimens of this group. 



LlBTJENIA BEEGI. 



The name Liburnia cognata, Fieb., having been unknown to Dr. 

 Berg when he published his work, I propose to re-name his species of 

 this name Liburnia Lergi, and so get rid of any confusion, although 

 I believe Fieber's species to be L. Aubei, Perris.
