Pascoensis is the Western Nycteis. The upperside is very simi- 

 lar to Nycteis, being a little less dark, as the black markings are 

 less broad. On the underside the dark markings and clouds are 

 obsolescent and faint, and much less obvious than in Nycteis, as is 

 well shown on the plate. 



The female of Nycteis is much larger than the male, and is also 

 differently and more strikingly marked, insomuch that it looks like 

 another species ; so, when the female of Pascoensis is found it will 

 probably be much larger than this figure of Pascoensis, much 

 handsomer, and so different that you may think it another and 

 larger species ; but at present the female of Pascoensis is not 

 known. 



Pascoensis will be found over all the interior, semi-arid region 

 of Eastern Washington and Oregon and Idaho. 



Food-plant : Actinomeris, probably.

 Tharos is considered an eastern species, but of late, say since 

 1892, it has become common, or at least, occasional, all over Ari- 

 zona and Southern California. I have specimens from Northern 

 and Southern Arizona, Yuma, the Mexican State of Baja Cali- 

 fornia, at the head of the Gulf of California, and as far north as 

 Santa Barbara ; none of them differ from the eastern species. This 

 fact establishes the point that a species can be the same, east and 

 west ; therefore, when forms do differ, they should be recognized 

 as different, and have separate names, as in the case of the preced- 

 ing, Nycteis and Pascoensis. 



Food-plant : Actinomeris helianthoides.
