HEEBIVOCULA. 399 



Genus HERBIVOCULA, Swinhoe, 1871. 



The genus Herbivoeula contains one species which, on account 

 of its thick bill, I consider desirable to separate from the Willow- 

 Warblers. Seebohm places it in his comprehensive genus Lusci- 

 niola, which embraces five of my genera wholly or in part. 



Herbivoeula is migratory, visiting the southern half of Burma 

 in the winter, and being somewhat rare. It has two moults, but 

 the only difference in plumage at the two seasons is that it is less 

 richly coloured in summer. The young are very yellow. The 

 sexes are alike. 



I found this Warbler, on the two occasions I met with it, in 

 bushes. It feeds a good deal on the ground, its strong tarsus 

 being suited to this mode of life. It has considerable affinities for 

 Anuidinav in structure and colour, but the tail is nearly square. 



In this genus the bill is very stout and deep for a Warbler, and 

 about one third the length of the head. The three rictal bristles 

 are very strong, and so are the supplementary hairs, which, how- 

 ever, do not extend up to the culmen nor cover the nostrils as in 

 Phyllopneuste. The first primary is very large, and the second 

 falls short of the tip of the wing by a considerable distance, being 

 equal to the eighth.

Coloration. Upper plumage olive-brown tinged with tawny, 

 especially on the rump ; wings and tail brown, edged on the outer 

 webs with the colour of the back ; supercilium very distinct and 

 reaching to the nape, buff ; lores and feathers behind the eye dark 

 brown : ear-coverts buff and brown ; lower plumage rich tawny 

 buff, paling on the throat and abdomen ; axillaries and under wing- 

 coverts buff. In summer the lower parts are nearly white, merely 

 tinged with yellow or buff, more especially so on the vent and 

 under tail-coverts.
