second segment with a rufous angular patch in the centre at the base, 

 remaining segments rufo-piceous, the second segment with lateral 

 cream-coloured maculae, acute within, the third and fourth with 

 acutely interrupted fasciae, the fifth with an entire fascia, and the sixth

The description of the male is from Panzer: I believe that sex has 

 not yet been captured in Britain, and that no one but myself has

 since which I have not met with it. It is a small pretty species, but 

 I have not been fortunate enough to find its " Metropolis."
