EPIDESMIA TRICOLOR, Westicood. 
PLATE XXVIIL Fig. 1. 
We refer this insect to the family of Pyralidae, on 
account of its general structure, although the ar- 
rangement of the veins of the wings differs from 
that of any of that family, having somewhat of a 
similar shape, with which we have compared it. 
The body is slender; the head small; the an- 
tennas long, slender, and filiform ; the palpi nearly 
three times as long as the head, compressed, slender, 
attenuated to the tip, bent downwards ; tlie spiral 
tongue long ; the fore wings large and somewhat 
triangular, with the apex acute and slightly falcate. 
The mesial vein of the fore wings emits three 
branches, the third of which is connected by a 
slender vein with the inner branch of the postcostal 
vein, a simple longitudinal vein extending from the 
base of the wing to the extremity through the 
middle of this cross vein; the first and second 
branches of the postcostal vein are not extended to 
the costal margin of the wing, hut form small 
oblong cells; the hind wings are large, with the 
outer margin slightly emarginate ; the abdomen is 
slender, but rather thicker towards the extremity ;
