dentate produced or obliquely truncate behind ; elytra and 

 wings of ordinary form ; the first and third articles of the 

 posterior tarsi equal in length. 



The species so far known occur in South America. 



Genus Lophotettix, nov. 



Resembling Gladiotettix {Nephcle\ but differing in liaving 

 stouter, more dilated, and llattened antennue, in the fewer antennal 

 joints, wliich consist of but ten distinct articles, the somewhat 

 stouter and more rugose body, the more distinctly compresso- 

 foliaceous dorsum of pronotum, and in the more laminate lateral 

 lobes. 



The type is L. hrevicristatus described below. 



1. L. hrevicristatus, sp. nov. (Plate XXII, fig. l,a&h.) 



A moderately crassate form (female) bearing a low dorsal crest 

 between the shoulders, the body strongly rugose, ferruginous. 

 Antenme very thick, consisting of ten conspicuous articles (a 

 minute barely distinguishable acute apical article might be considered 

 as the eleventh), the first article short and thickened, the second 

 small and globose, from the third to the seventh inclusive gradually 

 dilated toward the individual apices, the eighth and ninth dilated 

 at the middle and subexcavated longitudinally, the last articles 

 pale yellow, antennce inserted far anterior to or below the eyes ; 

 the posterior ocelli situated opposite the lower margin of the eyes. 

 Vertex very wide, transverse, not at all produced, little more than 

 twice the width of one of the prominent globose, substylate eyes, 

 the front transversely imperfectly carinate, bearing on each side a 

 small tuberculiform carinula next to the eyes opposite their anterior 

 fourth, and foveate on each side of the obscure median carina 

 between the middle of the eyes ; frontal costa abruptly widened 

 between the posterior ocelli, parallel, the facial carina above 

 depressed, costa between the antennse distinctly protuberant. Pro- 

 notum anteriorly truncate, but shallowly excavate at the middle ; 

 dorsum between the shoulders compresso-cristate (about three 

 millimeters in height above the shoulders), the crest highest between 

 the humeral angles, somewhat translucent punctate when held 

 against the light, the front margin roundly exca"\'ate, dentate- 

 crenulate, above anteriorly little angulate produced as far as the 

 anterior sulcus; dorsal margin of crest viewed from above not 

 sulcate but strongly sinuate; viewed in ]jrofile arcuate and crenulate- 

 sinuate, posteriorly opposite the articulation of hind femora, auberoae
