Three females of this species are at hand. They come from the 

 Province del Sara, Bolivia, where they were collected at 350 meters 

 above sea-level by J. Steinbach. C. M. Ace. No. 5058. 



The present species differs from the two preceding in having the 

 longitudinal lateral pallid lines composed of large, smooth, elevated 

 macula^, instead of being continuous. The geniculee of the hind femora 

 are bright ferruginous. 



Genus Henia Giglio-Tos. 



Henia Giglio-Tos, Boll. Mus. Zool. Anat. Comp. Torino, XIII, no. 311, pp. 45,

This genus is confined to South America, so far as our present 

 knowledge reveals. It contains insects of medium size, the known 

 species ranging in lengths from 15 to 21 mm. in the males, and 21 

 to 26.5 mm. in the females. Two species have been heretofore de- 

 scribed and the present collection contains what seem to be three 

 additional forms. All of the species are found very close to, or south 

 of, the equator, and in the interior. They ma}' be separated by the 

 annexed key.
