The fore-wings, on which all the transverse lines are dis- 

 tinctly marked, are pale yellow, extensively marbled with dark 

 brown and white. The half-line ends in a brown or black dot. 

 The first and second transverse lines are formed of brown 

 lunules, with the convexity directed inwards. The orbicular 

 stigma is distinctly yellow, ringed with white. The reniform 

 stigma is ear- shaped, with a dark centre. The claviform stigma 

 is represented by a black streak. The sub-marginal line is 

 white and clearly defined, and the marginal band is fawn- 

 coloured. The fringes are brown and whitish, and are edged 

 with a white line. The hind-wings are greyish-yellow towards 

 the base, with a slight lunule, and a curved line, beyond which 

 there is a brown band, and whitish fringes. 



The larva feeds on Viper's Bugloss {Echiuui vulgare)^ and on 

 Gypsophila paniadata in July. It is yellowish-grey in colour, 

 and is obliquely striped with darker on the back. 



The moth appears in May and June.
