Abila smaragdipes (Bruner) 



1911. Abila stnaragdi pes Brunpr, Ann. Carnog. Mus., viii, p. 96. [Para and 

 Santarem, Brazil.] 



Para, Para. (C. F. Baker.) One female. 

 This specimen fully agrees with Bruner's description. In the 

 presence of a continuous, distinctly sulcate, frontal costa this 

 form seems to us to approach the related genus Aristia, but at 

 present we are not in a position to make anj^ more definite state- 

 ment of the exact position the species should hold. It is, how- 

 ever, certainly not a typical Abila. 



Abracris obliqua (Thunberg)

p. 414. [Brazil.]

 1906. OmaloteUix signatipes Bruner, Proc. U. S. Nat. Mus., xxx, p. 673. 



[Sapucay, Paraguay (types); Pernambuco, Brazil; Temax, Yucatan.] 



Ceara, Ceara. (W. M. Mann.) One male, two females. 

 Baturite Mountains, Ceara. (W. M. Mann.) One female. 

 Maranguape Mountains, Ceara. (W. M. Mann.) Four 



males, two females. 

 Baixa Verde, Rio Grande do Norte. (W. M. Mann.) One 



female. 

 Natal, Rio Grande do Norte. (W. M. Mann.) Three males. 

 Independencia, Parahyba. (Mann and Heath.) Three 

 males, three females. 

 We have made a careful study of the species of this genus, 

 having material of all except the quite different conspeisipennis 

 before us, and find that Thunberg's obliquus is clearly the oldest 

 name for this species. For years placed in the genus Osmilia 

 and recorded a number of times under that generic name, there 

 is no question but that Thunberg had a member of this genus 

 before him. The original description is brief, but with Stal's 

 later comments from the typical material, and his synonymy of 

 his consors with Thunberg's species'''' the above synonymy of 

 signatipes is clear. 



Through the kindness of Prof. Bruner we have before us a 

 female paratype of signatipes, which is inseparable from the 

 females from the Maranguape Mountains. We have recorded
