140 Di/ar and Knab New Species of Mosquitoes. 



Wyeomyia melanocephala sp. nov. 



Prothoracic lobes entirely dark bluish ; head dark behind, without white 

 margin to the eyes ; hind feet with the last two tarsal joints white. 

 One specimen, Trinidad, B. W. I. (A. Busck).

 terial will probably enable them to be separated.
