This species was redescribed by Loew as H. latericia, but in a 

 note appended to the description he says he should have identified 

 it with qninquepimctata had not Say asserted the antennte of the 

 latter to be five spotted. This was a mistake on the part of Loew, 

 since Say said nothing of the kind, but located the spots on the 

 wing. 



(In my Catalogue I made Loew's plumata, instead of latericia, a 

 synonym of qninquepimctata; this I am now satisfied was due to 

 some confusion of names, as latericia is cleai'ly the synonym. —
