ODONESTIS may be briefly distinguished from the 

 allied genera by the length of the palpi, which have 

 the second joint double the length of the basal one, 

 and project in front of the head like a small beak, 

 and by the hinder margin of the anterior wings being 

 entire. The antennaB are strongly bipectinated, at 

 least in the male, as far as the apex, and they are a 

 little curved near the base. The abdomen is elongated 

 and furnished with an anal tuft in the male, which 

 is wanting, however, in the other sex. The hinder 

 margin of the anterior wings is rounded and entire, 

 but the angle formed by the tip is pretty acute ; in 

 the hinder pair there is a tendency to become den- 

 ticulate. The sexes are distinguished by differences 

 of size and colour similar to those exemplified by 

 the preceding species. The male is reddish-brown
