above. Forewings with vein 1 furcate, 2 from \ - \ of cell, 6 

 separate or out of stalk of 7 and 8, 7 and 8 stalked, 7 to costa, 

 11 from or before middle of cell. Hindwings as broad as fore- 

 wings, trapezoidal, apex long, acute, projecting, hind-margin 

 deeply sinuate-emarginate, cilia 2i-3; veins 3 and 4 remote at 

 origin, transverse vein bent outwards, 5 and 6 from rather near 

 together, 7 remote from 6. 



The genus may be regarded as consisting of two sections ; 

 A., in which vein 6 of the forewings rises out of 7, as in the 

 European M. binotellus (F.E.); and B., in which vein 6 of the 

 forewings is separate from 7, as in the European M. imparellus 

 (F.R.) ; it is to section B. that the New Zealand and Australian 

 species all belong.
