The southern specimens which I refer to otlw tend to a reddish shade 

 on the under surface; on the upper surface of the secondaries there are 

 some discal spots, while the primaries have fulvous on the basal half of 

 the costa, a complete series of subapical spots, and sometimes other ful- 

 vous marks in addition to those found in egeremet.

Under surface pale fuscous, sometimes tinged with brown; secondaries 

 rarely with a trace of discal marks above, and pale spots of primaries lim- 

 ited to three or less beyond the stigma and one or two subapical points. 



The females of otlw and egeremet have the same pale marks as the males.
