70 BRITISH CICADA. 



picturatus haunts principally the plains at the feet of 

 low outlying spurs to the mountains in Lower Austria, 

 and rarely occurs in the mountains ; whilst D. Flori 

 principally affects the Sub-Alpine regions, and seldom 

 comes down to the lower country. D. flori also is 

 known, he says, in Northern Europe, whilst (up to 

 1883) no record had been made of captures in these 

 latter parts. 



Its comparatively recent captures in Scotland and 

 East England, however, now remove this special 

 objection to their identity.

Mr. Edwards first recorded the capture of this insect. 

 It was taken by him in September, 1889, in Kanworth 

 marshes, Norfolk, and my figure is draAvn from a loan 

 specimen in his collection. It has a close resemblance 

 to D. punctum, but there appears to be an additional 

 black spot on the elytron. One of these spots is 

 placed on the first and the other on the fourth apical 

 area. 



Colour pale ochreous, and almost white. Elytron 

 rather reddish towards the apex, which has also a 

 darkish margin in juxtaposition with a short crescentic 

 white streak ; nervures white. Vertex and pronotum 

 about equal in length, and greenish. Abdomen yellow, 

 with a brown apex. Genital plates of the male at 

 least three times as long as the valve. Hind margin 

 of the female ventral segment, nearly straight. 



Size, 0*14 inch, or 3*50 millimetres.
