The genus Lusciniola, according to my views, contains but one Indian species. Seebohm, on the contrary, in addition to the present species, makes it include Tribura, Arundinax, Herbivocula, and a portion of Phylloscopus. From the first of these, Lusciniola differs in having fairly strong rictal bristles, and from the other three in having no supplementary hairs in front of the rictal bristles, and there are other differences in the shape of the wing and tail.
In this genus there appears to be a complete spring moult, but unaccompanied by any change of structure or by any noteworthy alteration of colour. The sexes are alike.
The Sedge-Warbler is quite aquatic in its Habits, being always found in reed-beds in or close to water, from which it is not easily dislodged. It is very likely to be a resident species in India as it is in Southern Europe.
L. melanopogon recalls to mind Acrocephalus bistrigiceps, from which, however, it may be separated at once by its large first primary.
Lusciniola has a slender bill about two thirds the Length of the head, two clearly visible rictal bristles but no supplementary hairs in front of them, the forehead being smooth and sharply defined ; the wing is fairly long, the first primary less than half the Length of the second, which reaches nearly to the tip of the wing; the tail is well graduated, and the tarsus of considerable Length.
