antenna; moderately prctliialcd on the hasal tlircc-t'onrllis. I'alpi vcrv 

 unequal in Icnglli hi i\\e sexes, usually sliort and slender: (he tliinl joint 

 short and conical, scarcely reacliing l»eyond the front in tlic male, while 

 they are longer in the female, and, as in Synchlora, of extraordinary length 

 and very slender, including the third joint. The wings are of very uniform 

 shaj)e. the fore wings being triangular with liie costa, rather straight ; the apex 

 subacute and the outer edge slightly convex, sometimes slightly l)ent or very 

 angular. Ilind wings round or angular, sometimes partly aborted (Di/sp(eris). 

 Venation : usually no subcostal cell' present, only in Dyspteris, and partially 

 formed in some species of Nemo r la. The costal venule anastomoses with the 

 subcostal; six well-marked subcostal venules; the independent venule mucli 

 nearer the sixth subcostal than usual, the posterior discal venule consequently 

 much longer and more curved than usual. The origin of the tirst median is 

 usually continuous with the main vein. Hind legs with the tibiae either long 

 and with a dense tuft or projection beyond the end, where the tarsi is very 

 short, or the tibiae are as usual and the tarsi equal to them in length. Some- 

 times but a single pair of tibial spurs. 



The species are green, usually with two common wliite lines and some- 

 times the front of the head and fore tibiae are a reddish or pink.
