B. Museum. I saw Polyommatus arion female rather darker on edges of wing & black spot plainer. Yet decidedly blue. There is Indian species, also, with Both sexes blue in about equal degree. – (In some exotic Thecla both sexes most generally blue & others of same sub-[genera] with female brown.)
we shd not have guessed sexual, if this only had been seen.
There is a splendid Indian orange-tip Butterfly in which both sexes nearly alike with orange tips, whilst the male alone of one has orange tips. The under sides of Indian species is wonderfully like leaf, whilst one likes flower of Umbellifer.
