Walsingham's cotype from North Carolina is in the National Col- 

 lection. It is a unicolorous, pale, faun colored specimen without the 

 markings shown in his figure.^^ Under this name we have also had 

 a series of some twenty-two males collected at Pullman, Washington, 

 during July and August by C. V. Piper. These Kearfott has de- 

 termined as Walsingham's species. Some specimens show a dis- 

 tinct, though pale, fawn-colored basal spot and a similar small spot 

 on dorsum before tornus. In others the entire wing is suffused with 

 very pale fawn color showing no traces of the above-mentioned 

 spots. The genitalia of the various specimens show considerable 

 variation but none quite agree with the cotype of luridana. It is 

 possible that luridana is an unusually variable species and may in- 

 clude all these extremes. I am inclined to think however that our 

 specimens represent two species. Rearing alone will decide. For 

 the present I am able to determine as luridana only four specimens 

 from Eureka, Utah (Tom Spalding), from Doctor Barnes's material. 

 Two of these are in the National Collection and two in his collection. 

 These agree with Walsingham's cotype in structure and color except 

 that the fore wings are a trifle more pinkish, possibly due to the age 

 of the Walsingham specimen.
