The male has the forehead crossed by a very narrow band of white; crown of the head, throat and all the upper surface dark slate-grey; chest rich rose-red, inclining to scarlet; lower part of the abdomen and under tail-coverts white; wings and the six central tail-feathers blackish brown; the three outer ones on each side tipped with white, the white predominating over the inner webs, particularly on the two lateral feathers; bill and feet blackish brown; gape and soles of the feet yellow. The female differs considerably from her mate, having the forehead crossed by a narrow band of buff; all the upper surface greyish brown; wings brown; secondaries crossed by two obscure bands of greyish buff; tail of a browner tint, but otherwise marked like that of the male. The figures are those of a male and a female of the natural size. [Illustration: PETROICA MULTICOLOR: _Swains._ _J. Gould and H. C. Richter del^t._ _C.

This beautiful Robin is a denizen of the wide extent of country reaching from New South Wales on the east to Swan River on the west, including Van Diemen’s Land and all the small islands lying off the southern coast. In Van Diemen’s Land it is much less common than on the continent, and is also far less numerous than its near ally, the _Petroica phœnicea_. I have not been able with any degree of certainty to trace how far it proceeds northwards. I believe, however, that a few degrees from the latitude of Sydney is the limit of its range in that direction. Although closely allied to the _Petroica phœnicea_, its structure on examination will be found to present some trifling modification, which better adapts it for arboreal existence; and although frequently on the ground, where it has much of the habits and actions of the _Saxicolinæ_, the low bushes and woods skirting the open plains and sterile districts are its favourite places of resort. Its food consists solely of insects of various orders, its modified structure enabling it to capture both aphides and swift-flying insects as well as the less agile _Coleoptera_.
