NORTH AMERICAN EUCOSMINAE. 83 



8. EUCOSMA MAGNIDICANA, new species. 

 (Fig. 208.) 



Dull rust red with silver markings on fore wing as in femaldana 

 Grote but considerably broader ; median silver bar broad, broken in 

 middle by a rather wide space of the red ground color; a broadly 

 triangular silver spot on costa near middle ; almost touching this and 

 separated only by a thin line of the ground color a similar large oval 

 silver spot on costa near apex; along dorsum a broad silver band 

 extending from base of wing almost to tornus; the silver markings 

 not so sharply edged as in femaldana. Hind wings dull grayish 

 fuscous. 



Male genitalia of type figured. 



Alar expanse. — 28 mm. 



Type. — In American Museum. 



Type locality. — Southwest Colorado. 



Food plant. — Unknown. 



Described from a single male from the Kearfott collection in the 

 American Museum of Natural History ("Dietz, 1899 "). A striking 

 and easily recognized species, nearest to E. femaldana Grote, but 

 distinguished from the latter by the width of the silver markings. 

 The genitalia are very much alike in the two species.
