Alar expanse, 47-52 mm. 



Type. — In the British Museum. 



Type locality. — Mexico, near Durango City. 



Remarks. — The racial status of pompeia (known from the female 

 only) is doubtful, and the genitalia indicate that it may be no more 

 than a form of aulaea occurring along with the typical race. This 

 form can be distinguished from aulaea by the darker and more con- 

 trasting markings. 



The specimen figiired by Barnes and McDunnough ^ as aulaea is in 

 the U. S. National Museum. This specimen is pompeia and was mis- 

 identified by Barnes and McDunnough.
