This may well be the male of one of the Indo-Malayan 

 species that have been described from female examples 

 only. It is apparently most closely allied to P. fornicata, 

 Br. from Burma, but is larger.

According to Kirby, who has compared the types, this 

 is synonymous with H. tcnehrosa, Wlk., a species placed by 

 Walker in the genus Panclilora ! It is somewhat doubtful 

 if tenehrosa, Wlk. is not the same as H. stylifera, Br., but the 

 wings are different in colour, and I hesitate to merge the 

 species without comparing the types. H. rujicornis, Sss. 

 and Zhnt. is also closely allied but can be distinguished by 

 the colour of the antennae.
