This rather large flycatcher is known in Thailand chiefly from Doi 

 Suthep, 4,600 to 5,500 feet, where it is decidedly uncommon and pos- 

 sibly present only in winter (December 15 to March 12). 



I have seen it, usually in pairs, only in dense, damp evergreen 

 forest. It is a quiet bird, with habits quite like those of its relatives. 



My specimens had the irides dark brown; the bill black; the feet 

 and toes dark brown; the claws dark horny brown or black. 



The adult male has the crown, nape, sides of the neck, the shoulder 

 patch, rump, and upper tail coverts shining ultramarine; the remain- 

 ing upperparts deep, shining purplish blue; the lores and sides of 

 the head black; the chin, throat, and sides of the upper breast black, 

 overlaid with purplish blue; the remaining underparts dull orange- 

 rufous, this color encroaching in an irregular point onto the center 

 of the lower throat. The adult female has the crown, nape, and sides 

 of the neck olivaceous-gray (each feather of the crown margined 

 paler to give a squamate appearance), changing to olivaceous-brown 

 on the mantle, this color strongly suffused with rufescent on the rump 

 and upper tail coverts; the rectrices and the margins of the outer 

 webs of the remiges rufous-brown ; a conspicuous eye ring rich buff ; 

 the feathers of the lores, sides of the head, the chin, and upper throat 

 rich buff, faintly barred with blackish; those of the center of the 

 lower throat unmarked buff, forming a patch that flares somewhat 

 where it meets the breast; the breast brownish gray, changing to 

 ashy on the flanks and abdomen, all of these parts often more or less 

 strongly washed with buff; the under tail coverts, under wing coverts, 

 and axillaries rich buff or buffy white.
