Bruner : Soi in American Loctj 133 



.11. Tarsi without pulvillus, the claws compressed, their base and apex of equal 

 width, the apex of which is provided with a deflexed point. Rudimentary 

 wings present in the female {stroma Charpentier. 



Genus Corynorhynchus Brunner. 



Corynorhynchus Brunner, Verh. der k. k. Zool.-Bot. Ges. in Wien, XXXIX, p. 101 

 (1890). 



This genus was erected to contain several species of walking-stick- 

 like locusts that occur in Brazil. They differ from other repre- 

 sentatives of the family in that the females have the rostrum of the 

 vertex more or less clavate. At least five species have thus far been 

 recognized. 



16. Corynorhynchus radula (Klug).

Habitat. — There are several specimens in the collection, which are 

 placed here, both sexes being represented. They were collected at 

 Rio de Janeiro. 



Another male specimen of this genus was taken at Chapada, near 

 Matto Grosso, Brazil. This latter may belong to a distinct species, 

 since it is considerably larger, being all of 80 mm. in length. 



Two of the females also may belong elsewhere, since the apex of 

 their rostrum is somewhat differently shaped from that of typical 

 specimens of radula as figured by Brunner in his monograph of the 

 family. 



Genus Tetanorhynchus Brunner. 



Tetanorhynchus Brunner v. Wattenwyl, Yerh. d. k. k. Zool.-Bot. Ges. in Wien, 

 XXXIX, pp. 92, 104 (1890); Giglio-Tos, Boll. Mus. Zool. Anat. Comp. Torino, 

 XII, No. 302, p. 18 (1897); Rehn, Proc. Acad. Nat. Sci. Phil., 1904, p. 677. 



The genus Tetanorhynchus was erected by Carl Brunner von 

 Wattenwyl to contain certain forms of the slender, apterous, stick- 

 like locusts, which occur chiefly in tropical South America east of the 

 Andes Mountains and between the Amazons and the northern regions 

 of the Argentine Republic. As stated in my remarks introductory 

 to the family Proscopidse all of these insects are rather variable in 

 their characters. The genera as well as the species, as at present 

 understood, cannot be definitely separated by the characters which
