$ , Unknown to me. 



Somewhat like the developed form of L. pellucida, but the apical 

 portion of the elytra is darker than in the last-named species ; and 

 the shape of the opening of the last genital segment when viewed 

 from behind, as well as the styloid processes, are totally different. 



Six specimens were taken by the Eev. T. A. Marshall (after 

 whom I have much pleasure in naming this insect) during his last 

 visit to Corsica.
