I have seen no specimen, among the hundreds examined, which 

 I could place here ; the insect remains a mystery to me and I 

 suspect some slip or misprint in Cameron's description of the 

 numerous alar corneous marks. 



* Except H. atricornis, Mori., var. zeylanicus, nov., which baa a minute 

 additional spot.
