supplemental carina?, as found in several species of the nearly related 

 genus Tettigidea coming from the same general region. Anterior to the 

 transverse sulci only a single one of these supplemental carinae is present, 

 while between the humeri two and sometimes even a third are found. 

 Lower posterior angles somewhat acute and turned down. 



General color variable, ranging from dull testaceous to dark fuscous or 

 dull black, the sides or deflexed lobes of the pronotum obliquely pallid, 

 the femora and tibiae together with the tarsi strongly fasciate with tes- 

 taceous and fuscous. Tegmina usually unicolorous but in some specimens 

 marked apically with a minute smooth pallid spot. Under surface of the 

 body pale testaceous or dirty yellowish white. 



Length of body, 9, 7.75-8.25 mm.; of pronotum, 9.75 mm.; to tip of 

 wings, II mm.; of hind femora, 5.25 mm. 



Habitat. — Chapada, Brazil, four female specimens taken by H. H. Smith 

 during the months of April, May, and June. The type is in the Carnegie 

 Museum, Pittsburgh. 



LoPHOSClRTUS gen. nov. 



Related to both Tettigidea and Batrachidea, from which genera its 

 members differ chiefly in the characters of the vertex and frontal costa. 

 General form slender. 



Top of head gently depressed, usually as wide as or a little wider than 

 the diameter of one of the not very prominent eyes; the vertex, viewed 

 laterally considerably advanced beyond the anterior margin of the eyes, 

 from above broadly rounded, its middle somewhat emarginate, the antero- 

 lateral carinae prominent, continued to and bent to the rear along the inner 

 edges of the eyes; median carina very prominent and high, forming an 

 arcuate crown in continuation with the prominent frontal costa, the latter 

 narrowly but deeply sulcate to its very summit. Antennse short, 15- or 

 i6-jointed, located between the middle of the lower half of the eyes; lateral 

 ocelli small and situated just above the middle of the eyes. Maxillary 

 palpi with the two terminal joints greatly flattened and enlarged, — pallid 

 and therefore very prominent. Pronotum elongate, narrow, the anterior 

 margin angulate and extending forward upon the occiput at middle, where 

 it terminates in a strong spine; lateral carinse very prominent in advance 

 of the transverse sulcus, median carina also quite prominent throughout, 

 the dorsum furnished with a series of continuous supplementary carinae. 

 Tegmina of moderate size, elongate, narrow. Anterior and middle femora 

 slender, plainly sulcate, their carinae in nowise undulate or clypeate; 

 hind femora also slender, comparatively smooth, the upper carina ter-
