The adults in this series all have the proximo-lateral portion 
of the tegmina, to near the costal margin, and the exposed portion 
of the wings, uniform warm buff. Such paler coloration is only 
shown as a narrow sutural border of the exposed portion of the 
wings in adults before us from Costa Rica. Similar presence or 
absence of pale tegminal markings is found in Vostox hrunnei- 
pennis. Over certain regions but one color condition would 
appear to occur, though in restricted areas a multiplicity of color 
differences are sometimes found, thus indicating the valueless 
character of such differences even for racial distinction.
