NORTH AMERICAN EUCOSMINAE. 129 



Tyfe locality. — Elk Point, South Dakota. 



Food plant. — Unknown. 



Described from male type and one male and five female paratypes 

 collected at Elk Point, South Dakota, by C. N. Ainslie (Aug., 1913) 

 and three female paratypes from Sioux City, Iowa (C. N. Ainslie). 



112. EUCOSMA ASPIDANA (Walsingham) . 



Paedisca aspidana Walsingham, Trans. Ent. Soc. Lond., 1884, p. 140. 

 Eucosma aspidana Fernald, in Dyar List N. Amer. Lepid., no. 5147, 1903. — 

 Barnes and McDunnough, Check List Lepid. Bor. Amer., no .7031, 1917. 



This species is placed here provisionally, as I have never seen a 

 specimen matching Walsingham's figure or description. Both would 

 seem to indicate a form similar in color and general habitus to 

 pulveratana. On the other hand, the parallel white lines on fore 

 wings would suggest something similar to dilatana. Walsingham. 



Alar expanse. — 17 mm. 



Type. — ^In British Museum. 



Type locality. — Arizona. 



Food plant. — ^Unknown.

114. EUCOSMA BIQUADRANA (Walsingham). 



Paedisca Mquadrana Walsingham, Illus. Lepid. Heter. Brit. Mus., vol. 4, 1879, 



p. 45. 

 Eucosma Mquadrana Fernald, in Dj^ar List N. Amer. Lepid., no. 5110. — Barnes 



and McDunnough, Check List Lepid. Bor. Amer., no. 6963, 1917. 



I have seen nothing that answers satisfactorily to Walsingham's 

 description and figure, though his species undoubtedly belongs in 

 this immediate group. The nearest thing to it is Kearfott's pcdou- 

 ■sana, but that has too pale a head and thorax.
