Northern Affinities of Chilian Insects

Abstract

I THINK I may be allowed to express my surprise at Mr. McLachlan's statement that this subject has never yet been “even more than casually alluded to in works on geographical distribution,” and is “ignored in the principal ones;” when I have devoted no less than six pages of my book on “The Geographical Distribution of Animals” (vol. ii. pp. 42-48) to a discussion of the main facts—quite as much as could be properly given to it in a general work. It is, however, well worthy of a detailed study, which I am very glad is being undertaken by so competent an entomologist. I hope Mr. McLachlan will endeavour to obtain collections of coleoptera and other orders of insects from the higher tropical Andes, where, I feel confident, some northern forms will also be found.
