Brunkr : South Amkkican Tktrigid.'R. 127 



g. Smaller (9. 11-12 mm. in length); the supplemental, longitudinal 

 carina; visible but inconspicuous (Bolivia, Paraguay, Argentina, 



and southwestern Brazil) muUicoslala Bolivar. 



gg. Larger (9, 15-16 mm. in length); the supplemental carina; very 

 conspicuous (Chapada, Brazil) corrugala sp. nov. 



Tettigidea annuUpes sp. nu\. 



\'ery similar in size and general form to T. subaptera, which is described 

 on a succeeding page, but differing from it in being a little more robust, in 

 ha\ ing the anterior edge of the pronotum spineless and in having the entire 

 surface glabrous or more or less varnished in appearance, although the 

 disk of the pronotum is quite strongly rugose instead of granulose as in 

 siihaptera. Wings abbreviated or wanting. Vertex reminding one of that 

 of the North American T. prorsa Scudder. 



Head high and narrow, the front somewhat oblique; top of head between 

 the eyes with prominent longitudinal rugaj and deep sulcus; the vertex 

 strongly projecting in front of the eyes, the lateral oblique carinte partially 

 obliterated or low next to the eyes; frontal costa prominent, coarse, not 

 very deeply but narrowly sulcate.. viewed in profile broadly rounded. 

 Pronotum short, subangulate in front, without the spine so commonly 

 found in the South American species of the genus, subtectate anteriorly, 

 the median carina coarse and prominent, viewed laterally arcuate between 

 the shoulders and front edge; rather strongly rugose at sides and on the 

 disk and on the latter between the shoulders tending to form a longitudinal 

 carina on each side midw^ay between the median and lateral carinae; apex 

 blunt, reaching to the base of the supra-anal plate, which is long and acumi- 

 nate, the basal half formed of two leaf-like lobes, cerci long, rather heavy, 

 and adorned with a number of long stiff hairs; valves of the ovipositor 

 long and slender, strongly serrated. Hind femora robust, smooth, reach- 

 ing the tips of the ovipositor. Two outer joints of the maxillary palpi 

 broadly dilated and sulcate externally. 



General color above and on the sides of abdomen piceous,. all the legs 

 (including hind femora) prominently fasciate with dull testaceous; lower 

 side pallid, apical joints of palpi dirty white. Tegmina fuscous, uni- 

 colorous. 



Length of body, 9 , 12 mm.; of pronotum, 8.75; of hind femora, 7 mm. 



Habitat. — A single female specimen, the type, is before me. It was 

 collected by H. H. Smith during the month of May at Chapada, near 

 Cuyaba Matto Grosso, Brazil. Carnegie Museum, Pittsburgh. 



There is also a single male among the large number of specimens of
