Temptresses (6)
I believe the answer is:
sirens
'temptresses' is the definition.
('siren' can be a synonym of 'temptress')
This is the entire clue.
(Other definitions for sirens that I've seen before include "Sea nymphs" , "Loud warning signals" , "Warning devices with loud wailing noise" , "They lured mariners on to rocks with loud whistles?" , "Alluring women" .)
