20/56 Under these conditions we may expect to find other moths which are not so protected imitating them, and this is the case. One of the common and wide-ranging species (Opthalmis lincea), found in the islands from Amboyna to New Ireland, is mimicked in a wonderful manner by one of the Liparidae (the family to which our common "tussock" and "vapourer" moths belong). This is a new species collected at Amboyna during the voyage of the _Challenger_, and has been named Artaxa simulans. Both insects are black, with the apex of the fore wings ochre coloured, and the outer half of the hind wings bright orange. The accompanying woodcuts (for the use of which I am indebted to Mr.John Murray of the _Challenger_ Office) well exhibit their striking resemblance to each other. |
