 smallest and oval, the inferior quadrangular. An ochery- 

 yellovv band is situated on the humerus and a second upon 

 the posterior margin, but does not reach the tip of the 

 wing. A similar band extends across the lower half of the 

 inferior wings. 



Under surface of superior wings similar to the upper — of 

 the inferior, reticulated with brown. The alar extent If

 form and size of the white spots on the superior wings 

 differ in the two. The absence of a large quadrangular 

 spot and a different arrangement of the yellow bars mark 

 this as a new species. 



A specimen was captured in Northern Ohio several years 

 since — probably the only one ever observed in this section 

 of the country. The Rev. J. Bachman, on examining this 

 specimen in my cabinet, informed me that he once took a 

 similar one in his garden in Charleston, S. C, and sent a

 aware of its having been published.
