The present insect is represented in the material before us by 

 but two females, which agree with the original description but 

 are slightly larger than the maximum measurements. 



These specimens show, as Giglio-Tos states, that the species is 

 very near C. saltator (that author, however, using the synonymous 

 name X. hrachypterum). When compared with brachypterous 

 but otherwise typical females of saltator, we find our specimens, 

 as Giglio-Tos has observed, to be differentiated by the decidedly 



" This series has been recorded in part by Caudell, the macropterous indi- 

 viduals correctly, the brachypterous examples as the synonymous merulionale, 

 Proc. U. S. Xat. Mus., xxx, p. 242, (1906), and macropterous specimens 

 correctly by Rehn, Proc. Acad. Xat. Sci. Phila., 1907, p. 393, (1907). In 

 following Redtenbacher's Monograph, subsequent authors have ahnost with- 

 out exception been led into the error of considering the macropterous and 

 brachypterous conditions of llie present insect separate specific units.
