112 BRITISH CICAD.E. 



Legs pale bliie-green, and ciliated. Frons long ; cly- 

 l^eus short, and terminated by a longish rostral sheath. 

 The antennae brown, with two thickened basal joints, 

 and a compound, taper, setaceous prolongation. 



The last abdominal rings of the male are attenuated, 

 and the ultimate joint is dilated into a singular pincer- 

 like structure, composed of the genital plates and 



juncts. Fig. 1 c.

Amongst the insects said to be injurious to the 

 potato-plant, J. Curtis notes two small Tettigidag, viz., 

 Euptenjx solani, Curt., and E. picta, Curt. He gives 

 coloured figures of both these insects, which I think 

 are sufficient to identify them both with our own and 

 with foreign species. E. solani doubtless is Chlorita 

 viridula, the species now under consideration. As 

 many as a dozen may sometimes be found on one leaf 

 of the potato or of the mangold-wurtzel, and these 

 may be seen leaping about until the crops are taken up 

 in the late autumn. 



On the authority of Mr. F. J. Graham the eggs of 

 E. solani are white, shuttle-shaped, more pointed at 

 one end than at the other, and striated with numerous 

 furrows. No notice is made as to whether these ova 

 were deposited in a groove or on the open surface of 

 the leaf. So far as I know, the ova of the Typhlocy- 

 bidae are long, with rounded ends, and certainly not in 

 all species striated. They may not unfrequently be 

 seen, relatively large in number from eight to twelve, 

 and lying within the bodies of the females just ready 

 for exclusion in autumn. 



Where the insects are plentiful, the pupa-cases may 

 be found in multitudes, adhering to the foliage and 

 to the clods of ground below. 



Chlorita apicalis, Flor, has been recorded as British, 

 but I have not myself met with any example of the 

 nsect.
