Forbes (1924) gave a short description of this species, beHeving 

 that it was already published by Kearfott, and supposed it a proba- 

 ble variety of the European Acleris permufana (Duponchel). He did 

 not mark with his labels any specimen of the type series of robinsoniana 

 in the American Museum of Natural History, and McDunnough 

 (1934) was the first who selected ten specimens in that collection as 

 cotypes of this species. These specimens correspond well with Forbes' 

 original description of robinsoniana. Klots (1942) found it logical not 

 to restrict the type material of robinsoniana to the ten specimens se- 

 lected by McDunnough as "cotypes," but to treat all 83 specimens, 

 placed under this name in the Kearfott Collection, as the type lot, 

 inasmuch as Forbes did not select any preferred specimens. Although 

 not aU these "lectoparatypes" (as Klots called them) belong to the 

 nominate form of robinsoniana, the present author completely agrees 

 with Klots' proposal, especially in view of the fact that McDunnough's 

 selection was rather arbitrary because his "cotypes" did not include 

 all the specimens which correspond to the nominate form of this 

 species. There are nine more specimens of the nominate form of 

 robinsoniana in the type lot used by Forbes for his description, and 

 these specimens were not indicated by McDunnough as "cotypes." 

 Even though, in consequence of the proposal of Klots, the type series 

 of robinsoniana became somewhat "motley" because of the many va- 

 rieties which it includes, the lectotype selected by Klots is completely 

 typical of the nominate form of this species. The entire type lot of 

 robinsoniana in the American Museum of Natural History includes 

 the following forms. 



Form a, nominate form 



Forewings along dorsum with a pale-yellow streak slightly widened 

 externad; remainder brown, darker basad and apicad.
