Ill tliift series the male prozona is slifjlitly lonj^itudiiial, and t\w inter- 

 space between the inesosternal lobes exceptionally narrow, beinj; nunc 

 than twice, in the male.several times, as lon^r as broad, while the nieta- 

 sternal lobes are attinjijent over considerable space in the male, approxi- 

 mate in the female. The tegmina, especially those of the male, are 

 rarely, and then but little, maculate, always fully developed and sur- 

 passing the hind femora; the hind tibiae are green or blue, with nine to 

 eleven, usually ten, spines in the outer series. The antennae are of very 

 unecpial length in the two sexes. 



The supraanal i)late is more or less clypeate, the apex always well 

 angulate, and the median sulcus almost or quite obsolete; the most 

 striking feature is the furcula, which consists of a i)air of long, very 

 broad, ])arallel, depressed idates, reaching about to the middle of the 

 supraanal plate and at base largely concealing it, apically narrowed 

 ])artly or wholly by their interior rounded emargination; the cerci are 

 small, the apical i)ortion subequal, nearly straight, and about l«alf as 

 broad as the base; the subgenital plate is somewhat narrower than 

 long, subequal, apically extended slightly but not elevated, the lateral 

 margins straight and on a line with the upper side of the last abdomi- 

 nal segments, the apical margin well rounded as seen from above and 

 entire. 



The sj)ecies, six in number, are of medium or rather large size and 

 are found almost altogether in the soutiiwest; only one is known east of 

 the Mississippi,. and that only in the neighborhood of the main stream.

Grass green, more or less obscured with brownish olivaceous, 

 almost the only markings being a broad dark green band extending 

 from behind the eye across the prozona, directly beneath which iie 

 hitcral lobes are often spotted with Havous; and, less frequently, 

 a dusky green dorsal band from the posterior end of the fastigium 

 across the prozona, occupying most of the disk and leaving between 

 itKind the lateral band only a narrow greenish flavous stripe on the 

 lateral carinae. Head feebly prominent, the vertex gently tumid, the 

 interspace between the eyes moderately broad, as broad as the frontal 

 costa; the fastigium gently declivent and deeply and broadly sulcate; 

 frontal costa percurrent, eqnal, sulcate throughout, deeply excei>ting 

 above; eyes rather large, rather prominent, very much longer than 

 broad; antennae a little longer than (male) or about two thirds as
