The Cuban and Mexican forms of this Terias have usually been considered to be 

 distinct, the former bearing the name T. dina, bestowed upon it by Poey in 1832, the 

 latter that of T. westwoodii, given it by Boisduval in 1836. The differences between 

 the two, according to Boisduval, are chiefly those of size> and, to some extent, in the 

 coloration of the female. We have now an extensive series of this species, and the 

 variation on the mainland existing amongst them is such that we find it impossible to 

 distinguish the mainland from the island form, and we therefore unite them under 

 Poey's title. 



T. calceolaria of Messrs. Butler and Druce was based upon Costa-Rican specimens 6 , 

 which we have now before us, with rather a pale tint, but individuals of the ordinary 

 type occur with them ; moreover, we find both pale and dark specimens intermingled 

 throughout nearly the whole range of the species. The palest of our series are from the 

 neighbourhood of Vera Cruz, where Godman captured three specimens in January 

 1888 ; these also have a very narrow apical and marginal border. Examples from 

 Atoyac, taken in May, are also pale, but a little darker than the Vera Cruz ones ; the 

 Ruatan-Island specimens too are of a decidedly pale tint. Other points of variation 

 are to be found in the markings of the secondaries beneath, some examples being 

 immaculate, others pretty freely marked with dusky spots ; the females, too, vary as 

 regards the density of the ferruginous apical spots beneath, which in some specimens 

 are evanescent. 



T. dina flies nearly throughout the year, but in greater abundance during the wet
