Expanse 21 mil. This form is easily recognizable by tlie clear yellow 

 subterminal field, contrasting with the broad vinous terminal space and 

 the purple median field projected over median veinlets; above the ex- 

 serted portion of t. p. line the subterminal space is narrower. It 

 resembles onythesalis in disposition of colors on fore wings, but the pur- 

 ple terminal field is wider; the hind wings are discolorous, the colors of 

 primaries more intense, and defining clearly the separate fields of the 

 wing. The colors are darker than in laticlavia or cinerosa.
