Genus EUPLCEA. 
This and several of tlie following genera may be 
readily distinguished from any of the preceding by 
having the anterior legs, in both sexes, short and 
imperfect, the tarsi not being distinguishable into 
five joints, but generally consisting of a single piece 
with several crowded spines at the extremity. In 
the present genus there is a slight indication of an 
articulated structure, but very indistinct, and there 
are scarcely any projecting points in the room of 
claws. The antennas, which are placed very close 
to each other at the base, terminate in a pretty thick 
club elongated and somewhat curved. The palpi, 
which stand considerably apart from each other, are 
short, not rising above the head, densely clothed with 
hair-like scales which completely conceal the joints : 
of the latter the terminal one is minute and globular 
ending in a point, the second long and thick, the 
radical one about one-third its length. Outline of 
the upper wings triangular : claws simple. Chry- 
salis suspended by the tail, and never supported by 
a band round the middle.
