Genus LARVIVORA

The genus Larvivora contains two species, one of which is confined to India and the other is found in the eastern portion of the Empire and Eastern Asia in general. The first is a migratory, bird in a small degree, moving from the hills to the plains and back again according to season ; of the second very little is known except that it has a very extensive range.

In Larvivora the sexes differ in colour, and all the evidence I have been able to collect points to the fact that the nestling resembles the female. The position of this genus is therefore in this subfamily, to which its coloration, habits, long legs, and short tail further ally it.

In this genus the bill is slender and about half the Length of the head and the nostrils are long ovals. The wing is somewhat pointed, with the first primary of comparatively small size; the tarsus is slender and long and the tail is very much shorter than the wing, whereas in the Robins, to which the Blue Chats bear considerable resemblance, the tail is proportionately much longer.
