Posterior wings pale ochreous, cilia the same. 



The larva tapers from the third segment anteriorly and 

 posteriorly ; flattened above and beneath, submoniliform ; no 

 dorsal papilliform points, but two rows on the sides; abdo- 

 minal and terminal feet very short, the latter placed pos- 

 teriorly. Head small, cordate, horizontal. The body is 

 yellowish or pale greenish, the head, 1st, 2nd and 3rd seg- 

 ments black. 



It binds the leaves of oaks together, in August and Sep- 

 tember, and picks out the parenchyma between the network 

 of veins. In the latter part of September it weaves a slight 

 cocoon between two leaves (in nature it is probably made 

 elsewhere than between the leaves of its food plant), and 

 becomes a rather short, thick pupa, with the antennae-cases 

 moniliform and longer than the wing-cases, beyond the end 

 of which they project as an obtuse spine. It appears as an 

 imago in March or April. 



Labial palpi very long and recurved, the tips extending 

 back as far as the prothorax, but remote from the face 

 and head. 



(oU%\\ir P. rejlexella. Head brownish, tinged with ferruginous. 

 ' Labial palpi dark ochreous, with a black line on the edge of 

 the second joint beneath, and three black lines on the third, 

 one in front and one on each side. Antennae dark ochreous, 

 annulated with dark fuscous; basal joint with two black 

 stripes in front. Fore-wings dull ochreous, profusely dusted 

 with reddish-fuscous ; cilia short and dark-coloured. Hind- 

 wings fuscous. 



This species very closely resembles, physically, M. tentori- 

 ferella. The labial palpi are longer, however, more recurved, 

 and the second joint perfectly smooth, whilst in Tentori- 

 ferella it is roughened with scales. 



Both these genera likewise closely approach the European 

 genus Phibalocera, and it is not impossible that one of them 

 may be really identical with it, notwithstanding the longer
