20 BRITISH CICADA. 



Minute dots mark the terminations of the short 

 nervures. The abdomen ovate, and showing distinctly 

 six rings below the tips of the elytra, although eight 

 may be counted on the under-side. The point of 

 abdomen blunt, and ending with two short rounded 

 and flat plates, which enclose the genitalia. Each ring 

 of the abdomen is furnished with a black dash on each 

 side, and numerous punctuations. In the female a 

 triangular spot appears on the sixth ring, followed by 

 a black line, which is continued down the saw-case. 



Macropterous female. The rare macropterous male 

 I have never seen ; but, through the courtesy of Mr. A. 

 Piffard, I am able to describe the equally rarely-met- 

 with macropterous female, a single specimen of which 

 was taken by him on the hills near Tring, in Hertford- 

 shire : — 



Vertex less than one-third of the pronotum and 

 scutellum taken together. Two sinuous brown lines 

 run to the eyes below the apical spots. Eyes yellow, 

 with brown borders. A broad T-shaped band occurs 

 at the base of the pronotum. Elytra large, ochreous- 

 yellow, with an ill-defined brown fascia across the 

 upper parts. Nervures indistinct, but the inner mem- 

 branes of the areas fuscous. Style long, black, and 

 fringed, projecting much beyond the apices of the 

 elytra. Hind tibia densely fringed on the outer side, 

 and marked on the inner side by a longitudinal black 

 line. 



Some of the brachelytrous males are bright yellow, 

 with copper-coloured brownish elytra and finely punc- 

 tate bodies. 



Some years numerous at Weycombe, Haslemere, 

 during July and August. Common also on many 

 coast-sands and on dry heaths, Pitlochry. Mr. Edwards 

 notes a pale-coloured race of this species, about one- 

 half larger than the ordinary form.
