Type: male; Central America (U. S. N. M.). 



Allied to JE. cultrifera Stal, but differing in the raised lateral cari- 

 nas of the pronotum and the more general concave form of the same, 

 in the more elongate tegmina and wings, in the tridentate lobe on 

 the median tibiae, and in smaller size of the tympanum which is 

 cultrifera is larger in extent than the dorsum of the pronotum, 

 while relatively in elongata the same area is considerably less. 



Size rather large. Head more or less ruguiose; cultriform development of the 

 vertex rather long, lateral outline tapering, below moderately su lea te, apex shal- 

 lowly emarginate; eyes obovate, the apex directed upwards and backwards; 

 antennje filiform, annulated with blackish rings. Pronotum rather long; the 

 lateral carinfe heavy, rather rugose, considerably elevated ; anterior margin 

 broadly emarginate, the posterior arcuate; posterior margin of the lateral lobes 

 broadly arcuate, the anterior angle obtuse. Tegmina elongate; costal area com- 

 paratively narrow ; tympanum considerably less than the dorsal aspect of the pro- 

 notum in extent, the stridulating vein straight, transverse (arcuate in cultrifera . 

 Wings ample, almost reaching to the tip of the tegmina. Anterior and median 

 femora heavy and deep, sulcate below, the anterior with five spines on the lower 

 external margin; anterior tibiae rather heavy, straight; median tibiae with the 

 accessary lobe tridentate. Posterior limbs missing. 



As the specimen is very old, probably having been taken from alcohol, the 

 original coloration is totally gone, the specimen now being uniform brownish.
