Tettigidea chapadensis sp. no v. 



A medium sized, rather slender, dark-colored insect, in which the 

 pronotum is destitute of supplemental carinae and extends considerably 

 beyond the apex of the abdomen and tip of hind femora in both sexes. 

 Tegmina provided with an oblique subapical fiavous patch. 



Head small, rather deeply sunken into the front edge of the pronotum, 

 the vertex a little advanced beyond the eyes, the transverse carinse blunt 

 and inconspicuous: frontal costa fairly prominent and profoundly sulcate 

 nearly to the upper extremity, viewed laterally broadly and evenly rounded 

 to the ocellus. Antennae slender, of moderate length, situated just within 

 a line drawn from the lower edge of the eyes. Top of head between the 

 eyes but gently undulate, only slightly granulated. Pronotum long and 

 slender, anteriorly angulate and provided with a slender spine that reaches 

 to the middle of the upper edge of the fairly prominent eyes; disk finely 

 granulate and furnished with irregular, fine rugae and lines which are 

 inclined to run lengthwise, especially on its widest part; the median 

 carina is slender, straight, and most prominent anteriorly; lateral carinae 

 in front also slender, reaching the transverse sulcus, beyond the inter- 

 ruption nearly as prominent as the median. Legs slender, the hind 

 femora extending beyond the tip of the abdomen in both sexes. Tegmina 

 moderately large, elongate oval or sub-spatulate, rather smooth; wings 

 fully developed and extending considerably beyond the tip of the pronotum 

 in both sexes. 



General color above brownish, fuscous, or black, very seldom dull fer- 

 ruginous; below pallid, anterior and middle femora pallid, the tibiae and 

 sometimes the hind femora of the females maculate with testaceous: face, 

 lower part of cheeks, lower edges of pronotum obliquely, base of hind 

 femora, the tibiae, and under side generally flavous or dull testaceous. 

 Sides of abdomen also more or less vittate with pallid. The paler colored 

 females, and occasionally the darker ones, show a tendency towards 

 having the hind femora marked externally with a rather large pallid 

 patch. 



Length of body, cf, 6.35 mm., 9. 10 mm.; of pronotum, c?', 9 mm., 9, 

 II mm.; of hind femora, cf, 5 mm., 9, 7 mm.
