This species is very nearly related to cri^iipes, but easily distin- 

 guished by the front legs and the hypopygium, 



H. crinicauda exists only in one specimen, a male, taken by 

 Stæger many years ago, probably at Ordrup (but no locality is given). 

 It is the same specimen which was sent to Zetterstedt and described
