148 BRITISH CICADA. 



Small. General colour pale ochreous or whitish 

 yellow. Vertex rouudecl, and marked by two carmine- 

 red spots, which in some specimens appear as lines. 

 Pronotmn with a large simple semi-lunar carmine-red 

 spot, or divided in the middle so as to appear as two 

 triangles. Scutellum either spotless or with one or 

 two brown patches. Abdomen pale yellow, with reddish 

 segmental borders. Legs very pale or yellowish. The 

 third joint of the hind tarsus and the apex of the 

 second, in the male, black. Elytron pale, with a long 

 red streak close to the suture, but often this streak is 

 broken up into five or six irregular crimson patches or 

 into a line of crimson spots. The clavus sometimes is 

 entirely red, at other times the colour is represented 

 by numerous carmine-red atoms. The frons is rather 

 long, and prone to the ground. 



This pretty little insect is common in the autumn 

 months at Haslemere and many other places. It is 

 also common throughout France and Scandinavia. It 

 is said to feed on various trees, such as the wild plum 

 {Primus pacliis), the mountain ash (Sorbus aucuparia), 

 and the lime tree (Tilia parvifolia). 



Dr. Sahlberg mentions six varieties, one of which 

 was taken from the Scotch fir (Pinus sijlvestris) . 



The genitalia are very complex. The pygofer of the 

 male ends with two black laminae.
