These specimens have been compared with the Costa Rican individ- 

 uals previously recorded by the author.^" 

 Orphulella zapoteca (Saussure). 



1861. Ox[ycorijphus] zapoteca Saussure, Revue et Magasin de Zoologie, 2e

 N. Rhoads, A. N. S. P.) 



The specimens from Alta Mira, Tamaulipas, previously recorded by 

 the author as 0. tepaneca are referable to this species. The frontal 

 costa, however, is moderately sulcate in all the Tamaulipas individuals. 



Orphulella viridescens Scudder. 



1899. Orphulella viridescens Scudder, Canad. Entom., XXXI, p. 187. 

 [Mt. Alvarez, Mexico.] 



The specimens previously recorded by the author from Eslava, 



D. F., Mexico," are now before me. This species is quite distinct 



from any other mainland form, and rather closely related to 0. scudderi. 



DICHROMORPHA Morse.

[Sinaloa and Tepic, Mexico.] 



A^ide from the longer tegmina and wings this species differs from 

 viridis in the slightly more robust form and ■^he more acute fastigium 

 in both sexes. 



The range of this species now covers three States or Territories on 

 the west coast of Mexico — Sinaloa, Tepic and Jalisco.

 Clendon, A. N. S. P.) 



This specimen is uniform brown and does not exhibit the green 

 dorsum mentioned by Bruner as present in the type d^. This the 

 first definite record of the species.
