CARL VON HEYDEiV. 49 



IVepticula bis-trimaculella, n. sp., Heydon (E. Z. 

 1861, p. 40). 



Capillis nigro-fuscis ; conchula nivea ; alis anterioribus 

 nigris, macula parva basali, macnlisque cluabus siib- 

 oppositis pone medium albis, ciliis albis; tarsis rufes- 

 centibus. 



This species is nearly allied to Nep. suhhimacuIelUr , 

 Haworth, and of the same size. The tuft of the head is 

 brown-black; the lower part of the face reddish. The 

 antennas are brown-black, with the eye-cap and following 

 joint white, and the tips whitish. 



Anterior wings black, with a small white basal spot, and 

 two larger opposite spots, of which the costal spot is before 

 the middle, and the dorsal spot in the middle ; cilia of the 

 apex of the wing white. Posterior wings grey. 



Thorax and abdomen blackish, w^ith some paler scales 

 intermingled. Anal tuft reddish. Legs brownish, the 

 tarsal joints reddish. 



This is easily distinguished from Nepticula suhhima- 

 culella by the colour of the tuft of the head, and by the 

 antennae, and by the finer scaling and purer blacker colour 

 of the anterior wings. N. siibhimaculella has, especially 

 towards the apex of the wing, many paler rather metallic 

 scales mingled with the brown-black ground, and dark 

 scales extend further into the white cilia at the apex of the 

 wing. 



The description of the larva I will furnish afterwards. 

 The cocoon is oval, slightly curved, anteriorly rounded, 

 reddish. 



The larva mines a very similar blotch to that of Nepti- 

 cula suhhlmaculella, but in the leaves of the birch. I found 

 it the beginning of October at Hofheim in the Taunus 



1868. E
