British Homoptera-Cicadlna. 119 



white, hind margin narrowly pale. Sci;tellum yellow, with a 

 blackish triangle on each side at the base and a rust-red marking on 

 the disc in shape like a musical tuning-fork. Elytra (PI. II. fig. 9) 

 red-brown, darker behind, from the middle of the inner margin to 

 the costa a broad obhque white band interrupted at the claval 

 suture by a streak of the red-brown ground colour, membrane and 

 appendix smoky hyaline ; nerves punctured, dark red-brown, ni 

 the pale band white, those of the membrane dark brown, brachial 

 nerve with one or two white spots. Abdomen above black, beneath 

 rust-red. Legs yellow-red, a dark stripe on the outer side of the 

 middle tibiae. Length, 5^ mm. 



Of this fine and very distinct species I have seen hut 

 one female example, which was beaten from sallow in 

 Foxley Wood on the 10th September, 1885. This sex 

 may be easily recognised by its fine red-brown colour and 

 the breadth and obliquity of the pale band on the elytra, 

 which is similar in these respects to that whichwe find 

 in I. variiis male. Judging from the description it comes 

 near I. fasciatus, Fieb. (Eur. Bythosc, 455, 9),_ but 

 that species has the nerves of the clavus wholly white.
