This is a paler and somewhat smaller form of 0. eurojixxus, appa- 

 rently adapted to drier countries. It is of a beautiful sandy and 

 silvery pale tint, and the wings are only 6'8 to 7 inches iu length. 

 Tlie specimens are quite distinct in appearance from Scandinavian, 

 English, or German specimens of C. curojiceus ; but they are some- 

 what variable in colour and also in size. Those from the Northern 

 Punjab, from whence Hume's type came, have generally longer 

 wings and are less sandy in colour than those that appear in Sindh 

 during the winter. They agree entirely with typical specimens of 

 Severtzofi's C. paWuhLS from Turkestan, and also with some speci- 

 mens from Eastern Persia and Afghanistan. They often closely 

 approach the European C. europaus, which is more constant in its 

 coloration. The shape of the white spots on the primaries is variable 

 and does not give a constant differential character. As it is impos- 

 sible to draw an exact line between the two forms, I think it best 

 to treat them as subspecific forms only, though the extremes differ 

 considerably. 



Hah. Persia, Afghanistan, the Northern Punjab and Turkestan

 limits in the East unknown.)
