GENUS LOCUSTELLA Kaup. 
Very similar to Acrocephalus , but having the tail much more strongly 
graduated, the outermost rectrix falling short of the middle ones by more than 
of the tail-length, the tail- coverts almost equally long; the rictal bristles very 
small and inconspicuous. Two species of this northern genus are known as 
winter visitors to the Celebesian area.
