All the stigmata shown. Hind wings and under surface as in cupidis- 

 sima, which is a light red species." 



In Can, Ent., x, 234, the reference to cupidissima is more positively 

 made, but in Bull. Surv. iv, 173, the following are indicated as dis- 

 tinctive: 



"Darker than the preceding [cupidissima], purple brown, with 

 powdery ochrey markings; claviform indicated, collar unlined, a little 

 smaller than cupidissima.'^ 



The only specimen of Iwtula which I have seen labeled by Mr. Grote 

 did not agree with this description at all and was the same as the ohser- 

 vabilis of Mr. Graef's collection, belonging to the exserUstigma group 

 rather than here. Mr. Grote speaks of all these forms from California 

 only. I have them from California, Colorado, Arizona, Kansas, and 

 British Columbia.

This species is so decidedly and remarkably marked that no mistake 

 in its recognition seems possible. It is evidently referable to this group, 

 but seems to introduce a strong tendency to the style of niaculatiou 

 more general in the following exserUstigma group. I have seen only a 

 few specimens, and have not been able to study the male.
