EUBLEPTUS, new genus. 



Wing" Hubelliptical. with .sli(>-htly curved {interior margin and more 

 strong!}' arcuate inner border, apex rounded otf, narrow co-stal area, 

 and fee])ly developed anal area. The subcosta reaches almost to the 

 tip of the wing and fuses in the costa. Radius straight, parallel with 

 the subcosta. Radial sector issuing not far a))ove the middle of the 

 wing, twice forked, so that -l veinlets extend to the border. The 

 media sends out its gently curved upper l)ranch, furnished with a 

 dichotomous end, somewhat above the origin of the radial sector, and 

 further divides into 3 twigs oidy. The superior branch of the cubi- 

 tus, which arises near the base, also forms a short terminal fork, and

the inferior stem likewise separates into 3 branchlets. The 3 or -4 anal 

 veins remain simple and extend in strong curves to the inner margin. 

 The remote and irregularly distributed straight cross veins stand per- 

 pendicular to the course of the longitudinal veins. The head with its 

 large, arched compound eyes is nearly as broad as the thorax, which 

 consists of 3 nearly equal, never strongly united segments, and no 

 winglike pleurites can be discerned on the prothorax. The 10 distinct 

 abdominal segments are individualh' broad(>r than long, and very 

 similar to each other. Below the tenth ring follows a short segment, 

 on which the basal portion of th(^ many jointed proba])ly very long- 

 cerci are preserved.
