 This interesting species is grey along the margins 

 of the fore wings, which are ditfusely shaded oyer

17. Polia Theodori. 



This fine species, from Colorado, is almost white, 

 shaded with red over the primaries. The tibiifi are 

 unarmed ; the eyes naked. In the shape of the 

 thorax it is allied to Epicliyds and Aedon, and 

 together the three seem to form a group of Folia.

 this group somewhat, but appears to me to be a 

 true ILadena. This species is named after Mr. 

 Theodore S. Bailey.
