274 BRAZILIAN ORTHOPTERA 



As far as can be told from Brunner's description these speci- 

 mens represent the species named tuberculata by him, differing 

 as they do only in the apparently less rugose meso- and metano- 

 tum. This difference is one of uncertain value, as its importance 

 depends on the exact degree of interpretation of Brunner's, 

 "Meso- et metanotum punctis impressis, profundis scabra." 

 Our female specimens are all more or less distinctly but hardly 

 decidedly scabrose on those areas. We are inclined to believe 

 this feature is individual or environmental to a considerable 

 degree. The exact number of spines on the dorsal margins of the 

 caudal tibiae is of relatively little systematic value in this group, 

 as we have shown above under Tetanorhynchiis humilis. In the 

 specimens before us the number of spines on the external margin 

 ranges from nine to twelve and on the internal margin from ten 

 to thirteen. Brunner gives eleven to thirteen external and 

 fourteen to fifteen internal spines. 



We have concluded that of the females before us but one, that 

 from Independencia, is fully adult and that from Ceara Mirim 

 and one from the Baturite Mountains are what Bruner calls 

 "subimagoes,"^'* while the other Baturite Mountains females are 

 distinctly young. Our reason for so considering them, aside 

 from mere size, is that the first mentioned specimen has the 

 rostrum greatly developed and slightly longer than the dorsal 

 postocular portion of the head, faintly clavate and much blunted 

 at the extremity, with the form in section tetragonal. Those 

 considered "subimagoes" are similar to the material described 

 by Brunner, and have the rostrum not at more or but little 

 more than twice the length of the eye. Those considered 

 young have the rostrum quite abbreviate and similar in relative 

 length to that of the adult male but always blunter and broader 

 distad. The young male has the rostrum of similar general form 

 to that of the adult male but much shorter with a less decidedly 

 acute apex. 



The measurements of the adult female are: length of body (apex 

 of rostrum to apices of the ovipositor jaws), 124 mm.; length of 

 head, 23; length of rostrum, 10.7; length of pronotum, 20.4; 

 length of meso- and metanotum and median segment, 16.7; 

 length of cephalic femur, 12.4; length of caudal femur, 33.2; 

 length of caudal tibia, 36.
