Abdomen beneath deep testaceous with uioro or less of a rusty tinge. 



Length, ? , 2i lines. 



This species belongs to the section in which the males have the 

 plate near the apex of the antennco. It stands near I. Jlturaius, but 

 has not the apparently interruj^jted and irregular transverse band 

 below the apex of the clavus, as in that species, and the colour is 

 totally different. When the insect is in repose, the white patch at the 

 apex of the central nerve of the clavus, common to each elytron, is 

 very distinct. 



I have only seen two females taken by Mr. Douglas at Darcnth 

 Wood, in October, 18G6. 



This is one of the three species referred to by me at page 81, 

 vol. X, of this Magazine, which I was at that time unable to determine.

CICADULA, Zett. 



This is a group of insects which I think the author originally 

 brought together on account of the great external resemblance of 

 many of the species. They are twenty-three in number, and divided 

 by him into eight sections, which he defines, principally, by the number 

 and form of the apical areas of the elytra, and the neuration of the wings. 

 These are excellent characters, so far as they go. But, as the genitalia 

 of the whole of the Somoptera have since been ascertained to differ 

 much in structure, and play an important part in determining genera 

 and separating species, it cannot be wondered at that Cicadida should 

 cease to be retained as a genus. 



Flor, in the Rhyn. Livl.,vol. ii (ISGl), divides the species between 

 two genera, viz., Jassus and Typldocyha ; but there cei'taiuly is not, 

 80 far as is known, a European representative of the genus Jassus, 

 Fab. This arrangement cannot hold good any more than that of my 

 friend the Rev. T. A. Marshall, who subsequently described the ]3ritish 

 species in the Ent. Mo. Mag. 



Fieber, in the Verb. z.-b. ISGG, p. 505, Wicn, takes as his types 

 of Cicadula two species, C. quadripuiictata , Fall., and C. (Jass.) Jenes-
