70 LIST OF HOMOPTEROUS INSECTS. 



Elidiptera HUMERALIS. 



Obscure viridis ; vertex transversus vix concavus, antice truncatus ; 

 frorts heptagona, oblonga, plana, lateribus elevatis ; prothorax 

 transversus, bicarinatus ; mesothorax planus ; alee anticce sub- 

 tuberculatoe, tuberculo magno distincto basali, costa valde 

 dilatata, basi non obliqua. 



Dull green. Vertex much broader than long, hardly concave, 

 truncate in front ; the hind border more elevated than the lateral 

 borders ; front heptagonal, much longer than broad, quite flat, but 

 with elevated borders. Prothorax much broader than long, with a 

 curved keel on each side. Mesothorax flat. Fore wings slightly 

 tuberculate, and with a large dictinct tubercle near the base ; costa 

 much dilated, forming a broad shoulder at the base of each wing. 

 Hind wings vitreous, with pale green veins. Length of the body 3£ 

 lines; of the wings 9 lines. 



This species much resembles the preceding one in structure, 

 but may be distinguished from it by the broader and less oblique 

 basal part of the costa.

Elidiptera obliqua. 



Pallidissime albido-viridis ; vertex transversus, concavus, antice 

 truncatus ; frons transversa, carinis duabus latis abbreviatis, 

 margine elevato ; prothorax transversus, arcuatus ; mesothorax 

 planus ; alee anticce subrugulosa, basi tuberculata, margine 

 inter iore apicem versus venulisque nonnullis transversis fusces- 

 centibus, costa basi perobliqua ; posticce albidce. 



Very pale whitish green. Vertex concave, broader than long, 

 truncate in front; front very much broader than long, with an 

 elevated border, and with two short broad keels. Prothorax trans- 

 verse, convex along the fore border and equally concave behind. 

 Mesothorax flat. Fore wings slightly rugulose, with a few minute 

 tubercles at the base, with a slight brown tinge along the apical 

 part of the interior border and on some of the transverse veinlets ; 

 costa much dilated, very oblique near the base. Hind wings
