22 BRITISH CICADA. 



Cixius SIMPLEX, H.-Schciff. Plate VII., fig. 10. 



Flata simplex, H.-Schaff., Norn. Ent. 164 (1835). 

 Cixius distinguencliis, Kirschb. 



,, simplex, Scott, Fieb. 



,, Scotti, Edw., Ent. Mo. Mag. xxv. p. 160, 



Head and pronotum black. All keels brownish 

 yellow. Frons and clypeus black, with yellow carinas. 

 Elytra milky hyaline ; nervures delicate and finely 

 punctured. Dots eye-shaped (Edw.). Apex of claval 

 suture and a streak on the inner margin black. Thighs 

 black ; tibiae yellow, with a dark stripe. Apical lobes 

 of styles obovate; their stalks short and spreading 

 outwards. 



In great measure the above is Mr. Edwards' 

 diagnosis. This insect has been rarely taken in 

 England, and to the above gentleman I am indebted 

 for the means of figuring it. 



Mr. Edwards has recently revised his List of 

 British Cicadinae in the Ent. Mo. Magazine. He 

 there states that C. simplex of H.-Schatf. is not the 

 insect so called by Scott ; but he does not clearly show 

 in what the difference consists. He proposes to call 

 his new insect C. Scotti, but as no specimens available 

 to dissection have come into my hands, I still pro- 

 visionally call Scott's insect simplex. One character 

 given for C. Scotti is, " Costal granules twelve to 

 fourteen, occupying the whole width of the nerve;" 

 but in the example lent to me there appear to be 

 more than these numbers.
