Observations.— Decribed from three 9’s and one £ . It comes 
near to Culex guiarti , Blanchard, but can be told by the absence 
of green pleurae, and near C. azoriensis, Theobald, but can be 
told from that by the peculiar cephalic adornment and the 
venation and banded abdomen of the male, and from C. chloro 
venter in head adornment. 
Type in the British Museum.
