The genus is fairly numerous in N. America; the single 

 European species would appear to be a straggler.

not forming a raised tuft 2. proboscidalis. 



2. Second line with angular median projection 3. obsitalis. 



without angular projection . 1. rostralis. 



1. H. rostralis, L. 26-29 mm. Forewings rather narrow,
