NYCTIBORINAE 



Nyctibora brunnea (Thunberg) 



"1826. Blatta brunnea Thunberg, Mem. Acad. Imp. Sci. St. Petersb., x, p. 



278." 



Peixe Boi, east of Para, Para. November to December; 

 1907. (H.B.Merrill.) One male. 



We are unable to verify Thunberg's reference, but this speci- 

 men is clearly referable to Burmeister's holosericea, which is iden- 

 tical with Thunberg's species, according to Shelford. It is 

 closely related to Saussure's ohscura, but is of considerably larger 

 size, with proportionately shorter and more robust tarsi, and the 

 supra-anal plate of the male is broadly emarginate mesad and 

 immediately laterad of the same the margin is deeply U-emargi- 

 nate, the intervening points acute. In ohscura the same margin 

 is rounded mesad, with shallow sinuations laterad of the same 

 area. 



Nyctibora obscura Saussure 

 1864. N[yclibora] obscura Saussure, Revue et Magasin de Zoologie, 2e ser., 



xvi, p. 316. [Brazil.] 



Natal, Rio Grande do Norte. (W. M. Mann.) One male. 

 We have used this name as distinct from N. brunnea (Thun- 

 berg), with which it has been generally associated, as the present 

 individual fully agrees with the description of Saussure and is 

 distinctly under the measurements of brunnea as generally under- 

 stood. Certain other features of difference are mentioned above 

 under brunnea. 



EPILAMPRINAE 



Audlreia heusseriana (Saussure) 



1864. Epil[ampra] heusseriana Saussure, Revue et Magasin de Zoologie, 26 

 ser., xvi, p. 321. [Uruguay.] 



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



Ceara, Ceara. (F. Rocha.) One female. [U. S. N. M.] 

 The Para specimen has the pronotum distorted by an injury 

 which has completely altered its outline and made deep impres- 

 sions of the dark markings of the disk. The tegmina in both 

 specimens are subquadrate, the distal margin concave in both 

 specimens, but less so in the Pard one. In neither, however, is 

 this margin as oblique as in Saussure's figure of the species. ^^
