Primaries brownish white to tawny with some scattered dark brown 

 scales. There is sometimes a small dot near middle of cell and a dark dash 

 on costa over base of cleft, but botli are often lacking. A short distance 

 before the cleft and slightly toward inner margin there is a rounded dark 

 brown spot, rather well defined, which may be extended as much as half way 

 to the costa by an oblique line of dark scales, and occasionally the anterior 

 extremity of this mark alone is evident as a spot much more vague than the 

 first and preceded by some of the dark scales, grouped into a vague line. Apex 

 of first lobe, inner margin before apex, and sometimes tips of veins of second 

 lobe with dark dots. Fringes concolorous, those in cleft with dark areas, not 

 abruptly limited, just before apices of both lobes. In some specimens these 

 areas are not actually very dark, but they are always noticeably darker than 

 the wing. Secondaries gray brown, bases paler ; fringes slightly more tawny. 

 Expanse 21-29.5 mm. 



Distribution ; Type locality Siskiyou Mts.. S. Ore. Cal, July 

 and Aug. Colo., Aug. The type series was taken in June. Dyar 

 records one specimen, with doubt, from South Fork Creek, E. C. 



The large size and broad wings of Iiclianthi separate it at once 

 from the related species. We have a single specimen whose expanse 

 is about 21 mm., but this is very unusual ; the expanse is usually at 

 least 24 mm. The general habitus is very distinctive when once the 

 species is seen. 



r)ur Colorado sijccimens are from Denver and S. Park (fXslar) 

 and average smaller than Californian examples but are otherwise 

 aljout the same. 



Walsingham described Iiclianthi from seven specimens "bred from 

 larvae feeding on a species of ficliaiitliiis." One of these, now without 

 an abdomen, is in the Fernald collection, and the actual type in the 

 r.ritish Museum,
