The Rusty-throated Blue Wood-Chat, Jerd.
Coloration. Male. Forehead continued back as a supercilium, the upper tail-coverts, and a patch on the lesser wing-coverts near the edge of the wing bright ultramarine-blue; ear-coverts, lores, and in front of the eye black ; upper plumage and the sides of the head and neck deep purplish blue ; wing-coverts and quills black, edged with purplish blue ; tail black, suffused with purplish blue on the outer webs ; chin, throat, breast, and abdomen chestnut ; vent and under tail-coverts white ; under wing-coverts and axillaries pale chestnut.
Female. Upper plumage and the visible portion of the closed wing olive-brown tinged with rufous ; rump slaty blue ; upper tail-coverts deep blue ; tail black, the outer webs suffused with deep blue ; sides of the head fulvous olive-brown ; lower plumage, under wing-coverts, and axillaries rich ochraceous, becoming white on the vent and under tail-coverts.
I have not been able to examine a young bird, but it will prove, without doubt, to be spotted.
Bill black in the dry skin ; legs and feet brown. Length about 5-5 ; tail 2-3 ; wing 3'2 ; tarsus 1 ; bill from gape -6.
Distribution. Sikhim and the Khasi hills. In the former tract this species is a resident, probably moving vertically according to season. This bird is figured by Hodgson, and there are likewise some specimens collected by him in the British Museum, probably from Nepal, but there is no certainty on this point.
Genus ADELURA, Bonap., 1854.
The sole member of this genus is frequently associated with the true Redstarts, but the total absence of the chestnut in the tail, which forms so conspicuous a feature in all the Redstarts, induces me to place the present type apart from them. In habits this species appears to be a Redstart, and structurally it does not differ from Ruticilla. From lanthia, which it somewhat resembles in coloration, this genus differs in having the tips of the tail-feathers rounded.
