Mesopotamia and X. W. Persia. 595 



Melitcea casta. Wings above fulvons_, the costal strigte 

 of forewing and a broad [repanda] submarginal fascia 

 common to both wings, and the margin itself, black ; fore- 

 wings below with an irregular macular black fascia ; hind- 

 wings pale yellowish, with two very pale yellowish bands, 

 the broad stripes and the series of black marginal spots less 

 distinct. 



Exp. 15 '"-17"'. 



Next to M. didyma, from which, however, it differs most 

 in that the wings above have fewer l)lack bands and spots, 

 and that the bands of the underside of the hindwing have 

 almost disappeared. 



Melitcea 'persea. Wings above fulvous; forewings with 

 three black macular bands, hindwings two ; below, the 

 apex of the former and the whole of the latter pale yellow, 

 the macular bands of the forewings below conCorming with 

 those of upper surface, the hindwings \vith two pale fulvous 

 bands and black lunules and spots. 



Exp. alar. 17'". 



Similar to the preceding, but the markings of the liind- 

 wings on the underside, which in casta are very similar to 

 didyma, in this manfestly differ and come closer to M. didyma 

 [_sic !], from which, however, it ought to be separated, owing 

 to tlie failure of the black spots, especially at the bases of 

 the wings. 



Taking these two descriptions together, remembering that 

 Kollar also records M. phoebe from the same locality, and 

 assuming, I think with perfect justification, that tlie passage 

 in the above paragraph in italics must refer to some other 

 species, not didyma, it seems reasonable to suppose that 

 casta must be the Persian race of didyma and per sea that of 

 trivia. This view is much strengthened by tbe material in 

 the B.M. 



A character which may be found of some use in separating 

 tliese two species is the position of the black marks in areas 

 2 and 3 of the hindwing underside, between the orange 

 bands. These markings are generally, in each area, three 

 in number, and in trivia the middle one is nearer the distal 

 one, in didyma nearer the proximal one.
