3. METKIU8, Flor. 



The absence of markings on the head and other parts of this 

 insect, as well as the form of the posterior margin of the last abdominal 

 segment of the ? , with the two black spots, sufficiently indicate its 

 distinctness from all other British species. 



Seemingly very scarce. I only possess a single example.

 spot on each side in front of the anterior margin of the eyes. 



Head — crown with a small black spot on each side of the apex, and two others 

 larger and somewhat round in front of the anterior margin of the eyes. Face 

 black, with four or five short, fine, transverse, yellowish-white lines on each side,

 pitchy black, margins yellow. Lores black, or with yellow margins.
