calls distincl from the European R. cratcegala, on reconsideration after the 

 first examination I see no reason for separating our species from the latter.

 and palpi ferruginous; antennae darkochreous; oathe fore wings isa ferruginous, 

 incomplete, basal, curved line, largest on the costa ; a diffuse, slightly sinuate 

 line passing just outside and partially inclosing the very large, orbicular, brown, 

 discal ring, irised with yellow; an outer, submarginal, broadly sinuate line, 

 more distinct than the inner two, diffuse, dilated on the nervules, and espe- 

 cially on the costa; within and along the outer edge are a few transverse 

 ferruginous strigse ; fringe ferruginous. Secondaries very pale toward the 

 base, with a i'ew striga? toward the outer edges; no lines or discal dot. 

 Beneath, the wings are clear, witli sparse irro rations' on the costal and outer 

 border of the wing, and the discal dot is a round obscure spot, smaller than 

 above and centered with yellow ; a single wedge-shaped mark on the outer 

 fourth of the costa marks the site of the outer line. Fringe dark brown as

It maybe recognized at once by the unusually large brown ring, pupiled 

 with yellow, by the two mesial bands, which approach each other on the 

 costa and hind edge, and by the brown fringe on the fore wings becoming
