This species is represented b}^ a large number of specimens that 

 were collected both 1)}^ the writer and 1)}" W. T. Foster. It comes

 but it is known to have a wide distribution in Argentina immediatol}"

There are several female .specimens at hand that may belong here. 

 If they do they are hardly separa})le from the genus OrphuJeJla^ except 

 that in these specimens the space between the mesosternal lobes is 

 plainl}^ longer than wide, whereas in the various species of OrphvleJhi 

 it is decidedly wider than long. Since Giglio-Tos has described only 

 the male, the following brief diagnosis of the female may be added: 



Body slender, slightly compressed at thorax, the head about as hroad 

 as the front edge and about four-fifths as long as the pronotum, the 

 face rather strong!}- oblique; fastigium of the vertex forming about a 

 right angle, as in OrjJmhlhi. Pronotum a very little expanding on 

 hind lobe, which is but little, if any, shorter than the anterior; lateral 

 carina) in front of last transverse sulcus parallel, back of it somewhat 

 divergent. Tegmina of medium Avidth, not provided with discal spots, 

 extending considerably beyond the tip of the abdomen. Hind femora 

 a trifle surpassing the abdomen. 



General color a])ove testaceous or greenish, the sides of the head, 

 pronotum, and pleurw fuscous, bordered along the lateral carinre by a
