HaK Fukui. 



This species, having a blunt tooth on the hind 

 femora, is a Helcon as limited by Foerster; but it 

 differs from that genus in having a short horn — 

 flattened laterally and cleft at the apex — immediately

 especially the hinder; the claws simple. The eyes- 

 are oval and margined.
