On the Entomology of the Aru Islands, by Alfred Russel Wallace
Many fine things have thus been made known to entomologists, although the total number of species collected is very small; and it may, perhaps, be considered as one of the least known and most promising regions that remain, now that the most remote parts of the earth are ransacked by enterprising collectors.
I believe, therefore, that the insects of Aru and New Guinea are as closely related as those of Great Britain and the Continent of Europe.
