Capillis atris, antennarum conchula nivea ; alis anterioribus angustis, 

 fusco-nigris, parum caeruleo-raicantibus, fascia valde post medium 

 dilute aurea, nitida, ciliis obscure violaceis, apice griseis. Exp. 

 al. 2 Un. 



This species is easily recognised by the black bead, the narrow, 

 elongate anterior wings, throughout uniformly dark, and the pale golden 

 fascia placed unusually posteriorly. The frontal tuft is black ; the 

 cervical tuft and eye-caps white ; the antennae blackish gray ; in the 

 female shorter than the half of the anterior wings; the abdomen 

 metallic blackish gray; the legs black, with the tips of the tarsi 

 whitish. The anterior wings are extraordinarily long and narrow, 

 scarcely dilated posteriorly, of a uniform dark brown, with a faint bluish 

 tinge, scarcely shining; the fascia is placed at three-fourths of the 

 length of the anterior wings ; it is vertical, rather broad, pale golden, 

 very glossy. The violet- brown base of the cilia is well denned ; the 

 tips, as well as the posterior wings are fuscous. The under side is 

 fuscous ; the fascia of the anterior wings is indicated by the paler 

 colour, especially on the inner margin. 



The larva feeds in strawberry leaves, and was collected along with 

 that of N. fragariella in October, without any difference being observed 

 in it or its mine. The cocoon is also similar, rather broad and flat, 

 of a brownish yellow colour. Buchheister bred two females of the 

 species from larvae found in chalky places near Wolfenbuttel.

Capillis luteis (£), aut ochraceis (9), antennis brevioribus, conchula 

 flavida ; alis anterioribus, apice rotundatis, aeueo-nigris, postice 

 violaceis, subnitidis, fascia valde postica, subrecta, albida, dilute 

 aureo-nitida, ciliis apice cinereis. Exp. al. 1 J — 2j lin.

 Betula alba, No. 2 (larva and mine). Frey, Tin. 387, 24; Linn. 

 Ent. xi. 424, 42. 



Frey had only one female before him, and an additional description 

 seems the less superfluous, since the male differs in some specimens, 

 and Frey*s statements do not perfectly accord with those of Stainton. 

 In the male the frontal tuft is pale luteous-yellow, sometimes almost 

 dirty white, the small cervical tuft still paler, the eye-caps small and 

 silvery white ; in the female the frontal tuft is bright ochreous-yellow,
