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 antennas 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 roimded 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
