the remaining spots connected, forming a conspicuous patch with a 

 hooked branch turning towards abdominal margin ; the fulvous band 

 replaced by a narrower, deep orange or vermillion, projecting a branch 

 to the tail and surmounting two black spots on the margin. 



Body above brown, beneath white or grey; palpi white, fulvous at 

 base below, black above and at tip; antennae brown annulated with 

 white; club brown, tip ferruginous. 



Female. Same size. Upper side fulvous, with broad brown margi- 

 nal border to primaries, and a narrow edge of same color to secondaries, 

 preceded beyond the marginal spots by a faint brown lunulated line, 

 costal and abdominal margins also largely brown; the spots of under 

 surface repeated above; beneath, as in male, but lighter colored, the 

 whitish bands and the spots more distinct. 



Taken at Virginia City, Nevada. Collection of Dr. H. Behr. 



This species resembles Arota, Bois. The black spots of under side 

 are much heavier than in Arota^ and the orange band a marked fea- 

 ture.
