tinted with yellowish at the extreme apex. Cilia yellowish- 



- white. Hind-wings dark fuscous, cilia the same. Antenna? 



annulated with black and white. Head and labial palpi

Cth> |]<? C concolorella. The entire insect is of a uniform, rather 

 j dark yellow-ochreous colour. 



Taken on wing 13th of June. A single specimen. 

 I have other species belonging to this genus, but as they 

 are not in perfect condition I forbear to describe them. 



Ma em a e A, new gen. 



Hind wings setiform. The subcostal vein is faint, attenu- 

 ated and simple. The discal vein free, central and two- 

 branched. The median vein simple. 



Fore-wings narrowly lanceolate. The disk long, narrow 

 and closed. The subcostal vein is well defined from the base 

 to the first marginal branch, which appears to be a continua- 

 tion of it. But from the origin of the first marginal branch, 

 the vein is greatly attenuated and is deflected towards the 

 middle of the wing, and subdivides into two branches opposite 

 the point at which the first marginal branch attains the costa. 

 The two branches into which the subcostal divides are de- 

 livered one to the costa just behind the tip and the other 

 midway between this and the costal end of the first marginal 

 branch. The median vein is two-branched and is well defined 

 from the base to its branches, all of which are attenuated. 

 The posterior branch is short, and the next is delivered to 

 the tip of the wing and receives an oblique discal vein from the 

 last branch of the subcostal, which closes the disk. The sub- 

 median vein is simple. 



Head smooth, with appressed scales. Ocelli ? An-
