Genus EUPLCEA. 



This and several of the 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 antenna?, 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.
