lobes distinctly transverse. Abdomen slightly compressed, supra- 

 anal plate acute trigonal, the apex quite sharp and appreciably 

 decurved, medio-longitudinal sulcus distinct; cerci very small, sim- 

 ple, styliform; subgenital plate compressed, the apex produced, 

 acute rostrate, the ventral line of the produced portion carinate. 

 Cephalic and median limbs of moderate size, the femora slightly 

 inflated. Caudal femora about twice the length of the dorsum of 

 the pronotum, moderately slender, regularly tapering, pattern of 

 the pagina regular; caudal tibise about equal to the femora in length, 

 almost imperceptibly sinuate, spines on external margin ten in num- 

 ber including the apical one, spines on the internal margin numbering 

 the same. 



Color pattern similar to that of males of all the species of the 

 genus. Color on the sides of the dorsum of the pronotum, margin- 

 ing the median stripe on the head and covering the median section 

 of the tegmina blackish, the median stripe on the head, pronotum, 

 and anal area of tegmina tawny ochraceous. Costal area of the 

 tegmina and that of the principal veins of the same pale oil green. 

 Lateral lobes of the pronotum and sides of the head olive-green, 

 the edging of the pronotal lobes, the line below the eye, and the 

 proximo-costal streak on the tegmina buff. Eyes burnt umber; 

 antennae walnut brown. Pleura very dark olive-green; abdomen 

 and venter raw umber. Limbs pale oil green; the caudal femora 

 slightly brownish; the caudal tibia? a brighter green, with the spines 



entirely black.

Allied to ElxocMora viridicata (Serville) and E. humilis Kehn, but 

 differing from both in the tegmina and wdngs not reaching the apex 

 of the a])domen and in the fastigium being somewhat depressed cau- 

 dad and projecting so that the angle of the face is not straight, but 

 slightly concave. In the weak median carina of the pronotum it 

 agrees with E. liumms, but the coloration is more like E. viridicata. 



Size medium; general form and surface similar to other species 

 of the genus. Head with its exposed dorsal length slightly less 

 than half that of the pronotum; occiput very considerably arcu- 

 ate; the interocular area considerably depressed; fastigium mod- 

 erately acute trigonal, the apex when seen from the dorsum very
