114 BPilTISH CICAD^E. 



first, second and third radials nearly parallel, and 

 joined at about two-thirds of their length by four short, 

 more or less angular, transverse nervures. From the 

 pointed centres of these last, veins are carried to the 

 periphery, so as to make four apical areas. Similarly, 

 the three radials of the wing are nearly j^arallel and 

 connected ; the third being joined to the submarginal 

 vein by a straight nervure. 



Varied specific characters are to be found in the 

 details of the pygofers, male and female, and in deter- 

 mining doubtful examples, these details should be 

 studied. 



For a preliminary grouping of the species the fol- 

 lowing table may probably render some assistance, 

 although it be based only on colour and marking.
