DERMAPTERA. 



Family LABIDURID^. 

 Labidura xanthopus fStll). 



La Cumbre, Prov. of Cordoba. (Lizer.) One male. 



This individual is identical with, though very slightly smaller than, 

 the specimen from Puerto Bertoni, Paraguay, recorded by us as 

 Demogorgon batesi.^ Burr^ now considers the genera Labidura and 

 Demogorgon to be inseparable and synonymizes batesi of Kirby under 

 the older name xanthopus^ which action, as far as we can determine 

 from our material and the literature, is correct. Stal described the 

 species from Rio Janeiro and Buenos Aires, while Borelli has recorded 

 it from Salta, province of Salta, Argentina. 



Family LABIID^. 

 Labia minor (Linnaeus). 



Buenos Aires. (Lizer.) One male. 



The only previous Argentine record for this widespread species 

 is from Concordia (Borelli, BoUet. Mus. Zool. Anat. Comp. Torino, 

 XVII, No. 418, p. 6). 



Family FORFICULID^. 



Doru lineare (Eschsch.). 



Misiones. January, 1911. (Jorgensen.) Two males, four females. 



ORTHOPTERA (s. s.). 



Family BLATTIDiE. 

 Subfamily PSEUDOMOPIX.E. 

 Pseudomops negleota Shelford. 



Misiones. January 1, 1911, March 31, 1909, December 10, 1909. 

 (Jorgensen.) Three males, one female. 



Florincia, Rio Tapenaga, Province of Santa Fe. Two females. 



Alto Pencosa, Province of San Luis. December 20-22, 1908. 

 (Jorgensen; from composite Ximenedia microptera.) Five males. 



In none of the above-listed males is there any trace of the pale 

 antennal annulus referred to by Shelford and Rehn as occurring in 

 the female. The single female here listed lacks the greater portion 

 of the antennse. The latter specimen has the tegmina quite piceous, 

 with only the marginal field and the edging of the region of the costal
