LoPHOTETTix gen. nov. 



Related to Tctrix in the form of the vertex and to Teitigidea in ha\ing 

 the anterior femora plainly sulcate above. It differs from the former in 

 the elongate antenna?, the presence on the pronotum above of several 

 strongly developed uninterrupted supplemental carina', and in the elon- 

 gate, robust, but comparatively smooth hind femora, and from the latter 

 as de'^cribed in the synoptic table on page 92. 



Head of moderate size, wider below than above; the eyes not prominent, 

 subglobular, separated above by a gently depressed space about equal to 

 the diameter of one of them ; the vertex subangulate, advanced somewhat 

 in front of the eyes, the lateral carinae strong; top of the head between the 

 eyes broadly and shallowly longitudinally canaliculate at the sides, the 

 surface decidedly granulose. Frontal costa moderately prominent, above 

 and between the antenna?, narrowly sulcate nearly to the upper extremity. 

 Posterior ocelli situated between the middle of the eyes. Antennae long, 

 filiform, composed of about 20 joints, located between the lower extremity 

 of the eyes or a trifle below them. Pronotum elongate, rounded, not 

 angulate at the shoulders or sides: the anterior edge angulately produced 

 upon the occiput; transverse sulci scarcely apparent, the posterior ex- 

 tremity attenuate. Tegmina oblong, their apex rounded. Wings fully 

 developed, reaching the tip of the pronotum or beyond. Legs smooth, the 

 anterior and middle ones in nowise clypeate but plainly sulcate above; 

 the hind femora robust, elongate, smooth. First and third joints of hind 

 tarsi subequal, the first possibly a trifle the shorter; hind tibiee somewhat 

 dilated apically, the spines well defined. 



Lophotettix lineatus sp. nov.
