NORTH AMERICAN EUCOSMINAE. 249 



Type locaUty. — Scranton, Pennsylvania. 



Food plant. — Unknown. 



Described from male type and female paratype from Scranton, 

 Pennsylvania ("A. E. Lister, V-15-1905 ") ; one female paratype 

 from Hampton, New Hampshire (S. A. Shaw) ; two male and one 

 female paratypes from Sebec Lake, Maine; and three female para- 

 types from Mountain Lake, Virginia ("June 14-21, 1907, A. F. 

 Braun"). In addition to the specimens selected as types I have be- 

 fore me specimens from Hazelton, Pennsylvania, Framingham, 

 Massachusetts, and Wliite River, Ontario. 



This is the species that has been going under the name uncana 

 Hiibner in our lists. The latter does not occur in our fauna. In 

 carbonaTia. the hind wings are much darker and the mid-dorsal pale 

 patch is fainter than in the European species. The aedoeagus of the 

 male genitalia is also considerable shorter and the harpe narrower. 

 Kearf ott evidently noted the difference for he had some of the smaller 

 specimens set aside under the manuscript name carbonana^ which I 

 have here adopted.

Kearfott's diminuatana is nothing but the European diminutana 

 redescribed under practically the same name, and I am strongly of 

 the opinion that the so-called hiar-cuana Stephens is another syno- 

 nym. European authors separate the two on size and the difference 

 in the outer arch of the median white line of the fore wing. This 

 latter character is variable in our American specimens and we have 

 typical specimens of diminutana as large as hiarcuana. Both have 

 the same venation (3 and 4 of the hind wing very short stalked, 

 sometimes practically connate) and the same food plant. There is 

 no difference in their genitalia. 



Male genitalia figured from a Kearfott cotype in the National Col- 

 lection from Plummer Island, Maryland ("May, 1903, August 

 Busck").
