Two species are generally confused under the name of T. salius (Cram.). The 

 examples we refer to it agree very well with Cramer's figure and description ; the 

 others, which we separate under the name of T. longirostris (Sepp), constantly differ in 

 having the hyaline spot in the cell of the primaries comma-shaped. 



There is considerable variation in the number of the subapical spots in the females 

 of both species ; in T. salius they vary in number from one to three, and we have one 

 South-American example in our series in which the spots on the secondaries are 

 altogether wanting. On the underside, the apex of the primaries and a great portion 

 of the secondaries, the anal angle excepted, usually have a bluish or greenish tinge in 

 certain lights ; the secondaries, too, are constantly whitish at the base. Dr. Staudinger 

 has sent us a specimen of the present species under the name of G. mathiolus, 

 Herr.-Schaff. 



The South-American Hesperia fischeri, Latr., is another closely-allied form, but differs 

 in having the spots white instead of yellow, those on the secondaries being larger, and 

 these wings have not the pale base beneath. 



We figure a male from Bugaba, also the genitalia, for which see Tab. CVI. fig. 5.
