The present species is apparently nearest E. regina (Kirby). 

 It differs from the unsatisfactory description of that insect in 

 having the dorsal surface of the enlarged proximal portion of the 

 caudal femora rugose, coarsely and roundly subdenticulate along 

 the dorsal carina, in the proportionately broader tegmina and 

 apparently average larger size. 



The following description of this little known species is sub- 

 mitted for the convenience of future workers. 



Female. Size large. Vertex truncate distad, subconvex, trans- 

 versely bluntly but decidedly carinate; distinctly wider at sulcus 

 formed with frontal fastigium than in E. cyrtoscelis (Karsch). 

 Pronotum with a medio-longitudinal line, which becomes sub- 

 carinate in metazonal portion, terminating at caudal margin in a 

 small rounded tubercle, which scarcely projects caudad of that 

 margin. Lateral lobes of pronotum slightly higher than wide, 

 perpendicular, ventro-cephalic angles produced in a minute roundly 

 acute-angulate projection; ventral margin sinuous, with a produced 

 tubercle projecting from a prothoracic pleurite slightly caudad of 

 the ventro-cephalic angle; ventro-caudal angle broadly rounded 

 and weakly produced. Tegmina broad, expanding to meso-distal 

 point, where they are distinctly wider than in cyrtoscelis; distinctly 

 falcate distad. Ovipositor elongate, curved weakly upward. Sub- 

 genital plate convex, with distal margin rather broadly bilobate. 

 Cephalic and median femora rugulose, weakly carinate dorsad in 

 distal portions. Caudal femora heavy proximad, specialized as 

 described above. Ventral femoral margins armed (in the series) 

 as follows. Cephalic internal cf 3 to 5, 9 2 to 3; cephalic external 

 cT, 9 ; median internal cf, 9 ; median external c? 3 to 4, 9 3 to 4; 

 caudal internal o 71 7 to 8, 9 6 to 8; caudal external d 1 10 to 12, 

 9 8 to 12. 



Male. Agrees closely with female, differing as follows. Size 

 smaller. Median segment and first abdominal tergite each raised 

 -in a rather large medio-longitudinal crest, which is suddenly trun- 

 cate caudad. Cerci elongate, moderately stout but tapering 

 strongly and curving inward to apex, which is more strongly 

 curved inward and terminates in a minute tooth. Subgenital 

 plate elongate produced, deeply V-emarginate distad, the lateral 

 portions weakly divergent, tapering to their acute apices, with- 

 out styles, but each, unlike cyrtoscelis, armed with a minute sub- 

 apical tooth on the internal margin.
