Careful comparison of this series with material of C. varius 

 (Walker) shows these species to be very nearly related, as discussed 

 under that species. In Redtenbacher's key, pallidus is separated 

 from thunbergi Stal ( = varius) by its more slender form and more 

 nearly acuminate tegminal apices. These features are shown, by 

 the material at hand, to be worthless. 



From the localities given in the original description and the final 

 comments there made, we believe that more than one species may 

 be included, the data on the immature female from the Philippines 

 indicating that that specimen is probably referable to varius as 

 recognized by us. As a result, it is probable that a single type 

 must be selected for pallidus, before that name can be stabilized.

This is the species treated as acuminatus (Fabricius) by Redten- 

 bacher and Karny. Those authors failed to note that Locusta 

 acuminata Fabricius is a homonym of Gryllus (Tettigonia) acuminata 

 Linnaeus, as shown by the reference to Linnaeus given by Fabricius. 



The specimens here recorded agree closely with a series from 

 the Bonin Islands in the Philadelphia Collections. The majority 

 have the costal margins of the tegmina pale throughout, but in a 

 few specimens of the latter series a slight darkening is apparent. 

 Should the marginal coloration of the tegmina prove of no diag- 

 nostic value, as appears very possible, the synonymy of varius
