42 LEPIDOPTERA. 



Europe), has several times taken this species near Zurich, 

 in June. 



It may be the imago of the Lotus-eating larva. 



Nepticula betulicola, n. sp. 



Alis anticis fusco-aeneis, apice purpureo-tincto, fascia pos- 

 tica argenteo-albida ; capillis luteis, fusco-mixtis. Exp. al. 

 21in. 



Head and face yellowish, slightly mixed with fuscous ; 

 antennae fuscous, basal joint whitish. Anterior wings bronzy- 

 brown, considerably beyond the middle is a silvery-whitish 

 fascia, of variable breadth, placed nearly perpendicularly ; 

 the apical portion of the wing is purplish-brown ; cilia fus- 

 cous. Posterior wings grey, with grey cilia. 



Distinguished from all the allied species, by the proximity 

 of the pale fascia to the apex of the wing ; the fascia is more 

 posteriorly placed than in Micr other iella y and in that species 

 the fascia is not shining — here it is perceptibly silvery. 



Mr. Douglas met with the larvae of this species in October, 

 1854, at Headley Lane, mining in birch leaves ; it is thus 

 noticed in the Natural History of the Tineina, vol. i. p. 22: 

 — "An amber-coloured larva with g^een dorsal vessel, 

 making a small contorted gallery, of which the commence- 

 ment is filled with brown excrement, the latter half having 

 the greenish-grey excrement only in the central portion." 

 Mr. Douglas succeeded in breeding several specimens of 

 this little species; but this last autumn we have failed in 

 again meeting with the larva. 



Nepticula continuella, n. sp. 

 Alis anticis, basim versus, obscure ceneo-griseis, apice 

 saturate purpureo-fusco, fascia media saturate purpurea, 

 fascia pone medium tenui, recta, argentea; capillis ferru- 

 gineis. Exp. al. 2| lin.
