General color of the body and femora yellow ocher (doubtless 

 changed from green by drying), the caudal section of the pronotum, 

 tegmina (except for yellowish wash proximad) and tibiae warbler 

 green (Ridgway), becoming olive-green distad on the tegmina. 

 Eyes chestnut brown; antennae multiannulate with fuscous (only 

 proximal portion of antennae remaining). Tegmina with a longi- 

 tudinally disposed series of small fuscous spots between the discoidal 

 and median and ulnar veins, these placed one in each quadrate space 

 and the series weaker proximad, distad not reaching the apex, a 

 few weak scattered similar spots in the ulnar-anal area. Ovipositor 

 with the margins edged with mummy brown; infra-cereal plates 

 fuscous proximad. Cephalic tibiae with foramina fuscous; til^ial 

 spines ochraceous, narrowly tipped with black; caudal femora with 

 the vicinity of the bases of the ventral spines auburn. 



Length of body (exclusive of ovipositor), 28.6 min.; length of 

 pronotum, 7.2; greatest (caudal) width of pronotal disk, 5.8; length 

 of tegmen, 45.5; greatest width of tegmen, 10.4; length of caudal 

 femur, 32.8; length of ovipositor, 11.3. 



The type of this species is unique.

Igarape-assii. One male. 



So far as we are able to determine from the description of this 

 species the Igarape-assii specimen belongs here. The eyes, however, 

 are not black but auburn, while the tegmina show but two groups 

 of purplish bordered spots along the ulnar vein. Each of these 

 groups is composed of two distinct spots in contact with each other 

 except for the separation of the vein, the sutural one in each case 

 larger than the other. 



The only previous exact records are from Coca (Bolivar) and Valley 

 of Santiago (Giglio-Tos), Ecuador. 

 Scaphura sphex n. sp. (PI. II, figs. 38-40.) 



Allied to S. nitida, possessing the same polished surface of the body, 

 tegmina and exposed portions of the wings, the distinctive trans- 

 lucence or even transparency of the tegmina, and form of the same, 

 as well as the characteristic structure of the pronotum. The teg- 

 minal corrugations are similar in the two species. From nitida, sphex 

 differs in the relatively broader tegmina, which are also yellowish 

 hyaline except in the suffused distal fourth, in the wings being hyaline 

 in the same proportion (when at rest) as the tegmina, in the less
