fastigium of the vertex of hastata Brunner. Like both peUucida and 

 forcipata this insect has the sulcate pronotum. 



Moderately robust, body compressed; head small, depressed, the 

 fastigium of the vertex prominent, projecting beyond the front, its 

 sides parallel, in the male plane, in the female broadly and shallowly 

 sulcate. Pronotum smooth, the disc ridged in center anteriorly, 

 becoming flat posteriorly, where it is depressed, so that when viewed 

 laterally it appears somewhat arcuate, the middle provided with a 

 longitudinal depressed line. Tegmina coriaceous, the veining a little 

 Irregular, the hind margins evenly rounded. Anterior and middle 

 femora four-spined below; hind femora three-spined on exterior margin. 

 Supra-anal plate of male triangular, rather plain, cerci as m forcipata. 

 subgenital plate moderately long, tapering, tectate, and carinated 

 below, the apical third slender, deeply fissured, the parts finger-like, 

 Ovipositor somewhat sickle-shaped, widest beyond its middle, acumi- 

 nate, its lower margin somewhat crenulate on apical half; subgenital 

 plate tapering rather deeply, and angulately emarginate. 



General color chrome-green. Front whitish, pronotum, legs, and 

 lower side somewhat testaceous. Stridulating area of male tegmina 

 embrowned basally and centrally. 



Length of body, cf , i6 mm., 9 , 19 mm.; of pronotum, cf and 9 ,

 A third apparently new form is before me. It belongs to the same 

 section of the genus and is quite closely related to the preceding as 

 well as to albida and possibly also to rostrata. It, like chapadensis, 

 has quite a distinct structure of the vertical apical portion of the 

 supra-anal plate. In the present form it is scarcely a hatchet-blade, 

 but is rounded from above, has the lower side deeply and widely 

 emarginate, followed by a long slender tooth which is directed down- 

 wards. On the upper side and just at the base of the vertical portion 

 is located a prominent tooth with its apex directed anteriorly. Cerci 

 and subgenital plate very similar to that of albida. Ovipositor as
