Are you certain the top one is vomitoria? Brown basicosta and epaulettes (should be black in vomitoria), yellowy brown anterior spiracle (should be black in vomitoria, the white border on the lower calypter is not a threadlike white line around the edge. Both specimens have ginger hair behind the occiput, which vicina can have, but no red hair on the genae, which vomitoria should have and I am wondering if both are vicina, or the top one is some third species - what do you get in North America?

I take it you have the specimens?
