The generic names Eusceptis Hubner and Eugraphia Guenee are 

 isogenotypic. Guenee, 1852, accepted Hiibner's specific name, but 

 not his generic name. Instead, he proposed Eugraphia as the generic 

 name for irretita Hubner. The Hiibnerian generic name nas also 

 been ignored in aU subsequent taxonomic treatments and in all 

 catalogs. 



Head with proboscis well developed; labial palpi small, nearly 

 porrect, very slightly curved dorsad, third segment very short, second

 scales except longer and looser along ventral margin especially of two 

 basal segments; frons slightly bulbous, smooth or roughened medially,
