92 BEITISH CICADJI. 



General colour of a fine ferruginous yellow. Vertex 

 rather prominent but obtuse, with two dark apical 

 marks (interocellar ?) and three orange-red vertical 

 streaks. Pronotum with six such streaks. Scutellum 

 pointed, with four other streaks. Abdomen broad, 

 and pointed at the apex, the last segments being white ; 

 and in the female showing the black tip of the saw- 

 case. Sides of the abdomen and the edges of the 

 segments obscurely red. Elytra rather browner, very 

 acute at their apices, each of which is ended by a 

 short brown dash. The areas are varyingly filled with 

 fuscous-brown. Three small oblong dashes mark the 

 marginal border of the clavus. Nervures whitish, or 

 else pale fulvous. Wings hyaline and finely iridescent ; 

 nervures reddish brown. Legs greyish yellow or 

 brown. Inner side of the hind tibia often with a 

 narrow line and coarse outer bristles. Fore legs finely 

 setose. Under side brown, with orange lateral foldings 

 to the abdominal segments. Saw-case of the female 

 small and projecting. 



The jointed caudal process rises from within a deep 

 cavity in a conical termination : this aperture is oval 

 in form. Two peculiar roundish plates are seen above 

 the Cauda ; partially hidden by the edges of the said 

 opening. 



The female is larger, but less brightly coloured, than 

 the male. The frons is yellow, and shows a faint 

 barring, interrupted in the middle. 



The pointed character of the elytron, with its five 

 apical cells and small limbus, is characteristic of the 

 species ; and this character certainly removes it from 

 the ordinary forms of Thamnotettix under which some 

 have included it. 



The insect is common in most grassy places. Taken 

 at Albury, Hertfordshire, at Haslemere, and in the Isle 

 of Wight. I found it exceedingly common on the windy 

 heights above Ventnor, after the great "blizzard" of 

 March, 1891. They were quite active at the edges of 

 the deep snow-drifts in the hollows of the cliffs : they
