204 CATOCALA NEOGAMA. 



The strong resemblance which many of the yel- 

 low under- wings, as these moths are called, have to 

 each other, has rendered their synonomy somewhat 

 complex and confused. The species just decribed 

 has been thought not to be specifically distinct from 

 the Linnean Ph. paranympha (figured by Roesel, 

 iv. pi. 18, figs. 1 , 2), but it is of much larger size, 

 the wings are more evidently dentated, the outer- 

 most black bar on the under wings is uninterrupted, 

 and the inner one is not recurved anteriorly and 

 continued along a portion of the abdominal margin. 

 It is likewise nearly related to Catocala affinis 

 (West. Drury, vol. i. pi. 23, fig. 6), which is a 

 native of New York, but is at once distinguished 

 from that species by its yellow abdomen, and having 

 a yellow space along the margin exterior to the 

 black band on the under wings.
