ECPANTHERIA. I 25 



Ecpa7ithe7'ia is a very extensive genus of white Moths, with 

 black rings on the thorax and fore-wings. Nearly sixty species 

 are described from different parts of America, but only one is 

 common in the United States, though several are found in 

 Mexico, one or two of which perhaps extend northwards 

 beyond the frontier. The male is much smaller than the 

 female, and the anal angle of the hind-wings is often produced 

 into a lobe.

This Moth is remarkable for the disparity in the size 

 of the sexes. The wings of the female expand three 

 inches and three quarters, those of the male nearly an inch 

 less. Antennce black ; head white, with a black dot on each 

 side near the insertion of the antennae. Thorax with ten or 

 twelve black spots, some or all of them with a pale bluish-white 

 centre, making them appear annular : the two hinder spots 

 largest, and somewhat curved. Ground colour of the wings 

 white, the surface of the fore-wings varied with black spots, 

 most of which are ocellated, placed irregularly towards the
