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 (NejjJiele), but differing in having 

 stouter, more dilated, and flattened antennae, in the fewer antennal 

 joints, which 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 Z. hxvicristatus described below. 



1. Ii. brevicristatus, sp. nov. (Plate XXII, fig. 1, a&b.) 



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

 between the shoulders, the body strongly rugose, ferruginous. 

 Antennae 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, antennae 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 im^^erfectly 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 antennae 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 excavate, 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 ])rofile arcuate and crenulate- 

 ainuate, posteriorly opposite the articulation of hind femora, suberose
