(Tyrannidae; † Sharp-tailed Tyrant C. caudacuta) L. culex, culicis  midge; -vorus  eating  < vorare  to devour; "CULICIVORA   ...   Bill short. Wings very short, rounded; the first and second quills graduated; third, fourth, fifth, sixth, and seventh, nearly equal and longest.  Tail slender, lengthened and graduated. Feet long, slender; lateral scales numerous.   Type Muscicapa stenura. Temm., Pl. col. pl. 167. f. 3.  ...  The length of the legs indicates some peculiar economy, of which, at present, we are ignorant.
