black, parallel, curved, transverse lines on each side of the forehead. Crown : in the 

 male, two-fifths shorter than the pronotum, one-fifth longer in the middle than at 

 the sides, free sides feebly arcuate, apex widely rounded ; in the female, one-fourth 

 shorter than the pronotum, one-third longer in the middle than at the sides, free 

 sides nearly straight, apex widely rounded ; basal markings round, interocular line 

 widely interrupted in the middle ; frons with black side lines, and sometimes a dark 

 middle stripe. Pronotum with a few black points near the front margin, its disc 

 frequently more or less occupied by a dusky patch, which is divided in the middle 

 by a stripe of the pale ground colour. Base of the scutellum generally with a 

 triangle on each side, and a pair of points in the middle, black. Areas of the elytra 

 frequently more or less filled up by fuscous streaks, nerves pale, except that of the 

 inner jiiargin, which has its basal and apical thirds blackish. Abdomen black, the 

 connexivum beneath, and the hind-margins of the ventral segments narrowly, 

 yellow. ^Edeagus as in figures e andy. Legs greyish-yellow, with black lines and 

 points. Length, 85 — 4^ mm. 



In the field the most striking characteristic of this species is the 

 uniform pale brown appearance of the specimens ; and at home, either 

 sex may be easily recognised by the markings on the forehead. It 

 lives on Juncus articuJatus, on which plant I first took it in quantity 

 at Cley, on the Norfolk coast, in August and September, 18S8, and I 

 have since found it in the Norwich district wherever I have had an 

 opportunity of working its food plant. Possessing only a single 

 female in 1887, I regarded it as an intermediate variation between 

 G-nofata, Fall., and frontalis, Scott ; hence the description of the 

 former in my Synopsis was drawn to include all throe, and must, there- 

 fore, now be abandoned. 



CiCADULA ElEBERI, 11. Sp. 



Cicttdulo frontalis, Fieb., Cicad. d'Eur. (^Cicadala), 45, 5, nee Scott. 

 Upper fore-parts bright yellow ; prevalent form of marking on the head of the 

 male a pair of round basal spots, and a broad black band across the forehead, inter- 

 rupted in the middle by a cuneate stripe of the pale gi-ound colour, on this black 

 band the pale ocelli are very conspicuous, and there is generally a short oblique 

 yellow line continued outwardly from each ocellus to the lower angle of the band ; 

 sometimes the markings of the crown spread in such a manner that it is wholly, or 

 in greater part, black ; this is the state described by Fieber. Markings on the fore- 

 head of the female irregularly oblong, slightly arched, sometimes (by reduction) 

 perfectly crescent-shaped. Crown : in the male, one-fourth to one-fifth shorter than 

 the pronotum, one-third longer in the middle than at the sides, free sides feebly 

 arcuate, apex broadly rounded ; in the female, one-fifth to one-seventh shorter than 

 the pronotum, one-third longer in the middle than at the sides, free sides straight, 

 apex rounded; frons yellow, with the side lines, and sometimes a middle stripe, 

 blackish ; sometimes black, with the side lines and apex yellow. Disc of the prono- 

 tum IViqucnlly occupied by a dark fuscous patch, which is divided in the middle by
