IFcatl grcYisli-ochrooiis. Face dark fuscous. Palpi fuscous, termi- 

 nal joiut dirty oclireous. Antenna! dark fuscous. Anterior \vini,'s 

 dirty oclireous, coarsely irroratcd with fuscous, palest along the inner 

 margin ; cilia pale grey. Posterior wings grey, with paler cilia. 



Appears in August and October among Convolvulus arvensis,

Head smooth, the forehead obtuse. Antenna? as long as the body, 

 setaceous, with elongate joints, in the (J with very iJd'icate long hairs. 

 l^abial palpi rather long, smooth, slender, recurved, acute, the second

 cilia, the anterior narrow, the posterior extremely narrow. In the an- 

 terior wings the elongate diseoidal cell is not closed posteriorly ; the 

 four last branches have the base free ; three elongate branches proceed 

 from the median vein ; the submedian vein is posteriorly thickened ; the 

 sidjdorsal vein is simple. In the posterior wings the costal (?) vein 

 is furcate, one branch running into the costa, and the other into the 

 hinder margin ; the median vein emits four branches to the hinder 

 margin. 



Oidy one species is at present known in this genus; it has 

 long been known abroad (though in this country very rare), yet 

 its preparatory states still arc unascerlaincd; the Linnean asser- 

 tion, " Habitat in Aliii I'ohis subcutauea," not having been con- 

 firmed, 7uai/ be entirely erroneous, like the " Habitat in Fagi foliis
