M/ENOLENEURA, n. gen. 

 Neuration of the male unlike that of any Lepidopterous 

 insect known to me ; primaries with the subcostal vein 

 very thick and widely arched, throwing off its first branch 

 just beyond the cell, forking halfway between the cell and 

 the outer margin, each branch forking again, the first to 

 costa and apex, the second to outer margin, so that prac- 

 tically the main stem of the subcostal nervure runs to the 

 centre of the outer margin ; discocellular transverse, no 

 radial veins ; median vein with one branch, the first and 

 second branches starting from the base as independent 

 veins, but the second connected with the base of the third 

 by an obliquely recurrent veinlet, the third median at its 

 extremity joining the subcostal ; the submedian and the 

 first median almost united at their outer extremities ; 

 secondaries without costal nervure, subcostal continued to 

 apex, its second branch being emitted from the end of the 

 cell; discocellular s zigzag; median vein four-branched, the 

 tAvo last branches being emitted from a footstalk ; antennaj 

 pectinated, legs rather long ; primaries of female with the 

 subcostal vein nearly straight, first branch emitted just 

 before the end of the cell ; second some distance beyond ; 

 third immediately beyond, forking close to apex ; fourth 

 from the base of the third and below it; upper radial 

 emitted fi-om the superior extremity of the cell ; loAver 

 radial branching fi-om the thii'd median near its base ; 

 discocellular transverse ; secondaries with the second 

 branch of the subcostal nearer to the first than in the 

 male, the radial emitted near to it ; discocellulars angu- 

 lated ; median vein as in the male ; antenna? less strongly 

 pectinated; otherwise as in the male. Type, M. anomala.
