Homoptera, 135 



middle ; thorax reddish above, the middle carinse yellow ; abdomen 

 brown above, the sides marked with yellow, and the segments 

 bordered with green behind. TJndersurface of the body yellow, the 

 femora, the extremities of the five first segments of the abdomen, 

 and a large spot at each side at its extremity green ; the base of 

 the five first abdominal segments rich cream-colour. 

 " Allied to R. pellucida and R. panorpceformis, Guer." 

 Twenty-eight specimens, all those specially labelled taken in 

 January, 1898, on the JSTorth Coast. An abundant and very 

 variable species, both in colour and neuration ; but without 

 exhibiting well-marked differences which appear to be of specific 

 or even varietal importance. Some of the specimens are of a pale 

 testaceous yellow, others are of a darker yellowish brown, with 

 the abdomen more or less green, with a black dorsal band, and 

 black sutures. The number of nervures in the costal cell before 

 the stigma varies from 8 to 11 ; the stigma covers about five 

 cross-nervures, and is generally but slightly browned, but in the 

 darker specimens (which are usually those with most cross- 

 nervules in the basal cell and elsewhere) it is blackish. The 

 subcostal space is always (?) empty ; but the two following- 

 longitudinal spaces are sometimes free, almost as far as the first 

 fork of the second longitudinal nervure, which is usually preceded 

 by a cross-nervure in each space ; or there may be one, two, or 

 three cross-nervules in each of these spaces, preceding the fork. 

 Sometimes the marginal third of the tegmen is mapped out into 

 three fairly regular areas ; but sometimes the neuration of this 

 portion is much more irregular. The shape, too, of the various cells 

 difi'ers considerably. 



7. Nogodina subviridis, sp.n. (PI. XY, Figs. 10, 11.) 



Long. Corp. 7 mm. ; exp. al. 20 mm. 



Female. — Testaceous ; abdomen, except at tip, green, with black 

 sutures, expanding in front, and connected ; front long, with 

 black lateral and central carinas, the latter crossing, and between 

 their upper part is a brown line. Sutures of pronotum more or 

 less black. Tegmina yellowish hyaline, with yellowish-brown 

 nervures; costal area with 11 or 12 cross-nervures before the 

 stigma, which is very large, extending between six or seven cross- 

 nervures, those towards its base being more or less yellow. Sub- 

 costal area free. The three upper longitudinal nervures rising 

 together from the upper angle of the basal cell ; the second forking 

 at three-fifths of its length, the third at one-foui'th. The fourth 

 is widely separated from the others at its base. It is parallel 

 with and closely approximating to the upper vein of the clavus, 

 and it throws off a branch upwards at two-fifths of its length. 

 The middle vein of the clavus unites with the lower one at half its 

 length ; lower branch of the clavus broadly brown, and united
