 a brownish-black bam! line, and foi/r similarly coloured lines from 

 the costa, and ///rce from the inner margin, all more or less broadly 

 bordered internally with pale fuscous, their exterior margins being 

 white ; the black apical ,yiof is oval. Posterior wings pale grey, with 

 whitish cilia. 



Not uncommon, appearing in May and August. The larva 

 mines in the leaves of the oak in autumn and July.

Head, face, palpi, and antenna3 white. Anterior wings j)carly-whitc, 

 with three dark fuscous lines from the costa and two from the inner 

 margin, all internally bordered with pale fuscous, sometimes very 

 broadly, thus making the apical half of the wing pale fuscous, with 

 merely white spots on the exterior margins of tlicse lines ; the black 

 ajjical Hpot is round. Posterior wings grey, with paler cilia. 



A^cry abundant in May and August. The larva mines the 

 underside of the leaves of the oak in autumn and July; owing to 

 the number of the oak-feeding species, the individual mines of 

 each have not yet been sullicicutly distinguished. Looking at 

 the infinite variety in every department of nature, it is probable 

 tliat the mine of each species has some distinctive peculiarity.
