tegmina. compressed, rather regularly tapering distad, the external 

 face with a well-impressed but irregular pattern of the pagina; 

 genicular lobes bispinose; ventral-external margin with a continu- 

 ous series of twenty-one to twenty-two spines, the ventro-internal 

 margin with a series of nine to ten spines restricted to the distal 

 section of the margin, the spines of both margins of similar size 

 and equally spaced, except that distad on the external margin they 

 are more crowded than elsewhere; ventral surface moderately chan- 

 nelled: caudal tibiae in actual length slightly surpassing that of 

 the caudal femora, faintly compressed proximad, the dorsal sur- 

 face moderately deplanate, dorsal margins regularly spined, the 

 ventral margins with a much sparser spination. 



General coloration of the head and pronotum light yellowish-olive 

 to ecru-olive, on the abdomen saccardo's-umber, on the venter of 

 the same bister; tegmina and exposed portion of wings courge-green 

 to light elm-green, blotched with chamois and cream-buff, probably 

 through dessication of the original green color; limbs saccardo's- 

 umber to ecru-olive. Eyes mottled prout's-browai and fuscous; 

 antennae amber-brown, greenish proximad. Pronotum with the 

 lateral angles of the disk rather obscurely hned with ochraceous- 

 buff, the short sulci (paired) which intersect the lateral angles of the 

 disk at the cephalic third are lined with black. Humeral trunk of 

 the tegmina and the principal veins of the same lined with buffy, 

 the veins other than those of the trunk with this passing into cedar- 

 green; discoidal field and the adjacent portion of the marginal field 

 with numerous, scattered, very small points of creamy-white. Ovi- 

 positor ochraceous-tawny, more or less distinctly edged with russet. 



Length of body, 29.3 mm.; length of pronotum, 7.6; greatest (cau- 

 dal) width of pronotal disk, 6.1; length of tegmen, 50; greatest 

 width of tegmen, 21.4; length of caudal femur, 20; length of ovi- 

 positor, 6.1. 



The type of this most interesting species is unique.

 This specimen is faintly smaller than the original measurements 

 and shows no sanguineous punctations at the base of the tegmina, 

 although the ivory areas and the rows of fuscous points bordering 

 the veins are well marked. It fully agrees otherwise with the 

 description.
