I was much interested by Mr. Lynran's careful paper on a species of Gortyna, boring in burdcck. If aerala, Lyman, is a good American species it shoutd have an alternative food plant, since the burdock is imported from Europe. From Mr. Lyman's detailed statements, the distinction from necopina is assured. The differentiation form nitela is not so clearly given.

With regard to nitela, Mr. Lyman is quite correct, that Guenée first describes nebris and then nitela; and in my catalogue of 1874 I give the two as distinct species in the above order of their description. But in my Buffalo Check List of 1875 I place nitela first; and in 1882 I retain this sequence and record nebris as a variety of nitela. But I am not agreed with Mr.Lyman that nebris, the white-spotted type, represents the original form the species. I think the whit filling in of the ordinary spots a specialization, therefore a variation from the original form of the species.
