This is the normal western type of C fieldii ; the latter is 

 represented by a species near to C. aurorina, which, though found in 

 the west, extends as far eastward as Assam ; whether the two forms 

 are distinct or not can only be decided by breeding. Of course the 

 present form is generally called C. fieldii in Indian collections; but 

 if it be that species, it should stand as var. edusina.

One male of typical C. erate was obtained at Murree on the same 

 day as the male of var. pallida ; Major Yerbury says that it does 

 not appear to be so common at Murree as the latter ; a second 

 fragmentary male from Camphellpore was also sent with specimens 

 of C. pallida. Both Col. Swinhoe and Mr. de Niceville seem to have 

 wrongly identified the form, though, as C. sareptensis was mixed up 

 with it, I may be mistaken in the case of the former gentleman : 

 Major Yerbury, however, quotes the species as " Colias hyale apud 

 de Niceville, C. sareptensis •a.'^wA. Swinhoe" ; he says that at Murree 

 it is not common. He further remarks as follows : — "When first I 

 arrived in Camphellpore and began to collect, I had no setting-
