as long as the head and pronotum taken together. 

 The hmd tibiae are without the fine black setal points. 

 The abdominal apex of the female ends with a black 

 saw-point. The post-scutellum is less developed than 

 that seen in D. Jiavipennis, and the yellow indented 

 patch there to be noted on the antepenultimate somite, 

 appears to be here wanting. 



Notwithstanding its synonym N. arideUus, it affects 

 wet herbage. Locally it is common. 



Sahlberg gives as a character of the male " valvula 

 genetali nulla," and also " hypopygio medio profunde 

 inciso." He states it as common near Helsingfors, 

 from July to September. 



Length of body with wings, 0*15 inch, or 3*25 

 millimetres. 



Two species of Dicramura are briefly noted in 

 Edwards's ' Synopsis of British Cicadinse,' which have 

 not hitherto come under my observation. Both are 

 rare in Britain. These are Dicraneura aureola of Fall. 

 — equal to Erijthria aureola of Sahlberg — and D. 

 pygmceiis of Douglas. The first insect was taken by 

 Mr. Norman in Findhorn Marsh, Morayshire ; and the 

 latter, which appears to be the smallest British species 

 of Dicraneura, measuring only 2*33 millimetres, was 

 captured in Darenth Wood. 



I have nothing to add to what has been written about 

 these elsewhere. I merely note them here amongst 

 what appears to be our eight indigenous species. 



1). aureola is said to occur, in August and September, 

 on the ling of our heaths, Calluna vulgaris. 



Genus XLV.— KYBOS,* Fieher. 



Vertex rounded and shorter than the pronotum. 

 Ocelli visible. Elytron longer than the abdomen. 

 Limbus wanting. The first and recond radial of the 



'-'' So-called by Fieber, perhaps from the somewhat cubic form of the 

 vertex, which he describes as " trausversalement quadrangulaire."
