Notodontidae 
Genus EUHYPARPAX Beutenmuller 
The only species of the genus as yet known is that to which 
Beutenmuller applied the name 
rosea. It is a native of Colorado, 
and is as yet very rare in collec¬ 
tions, only one specimen, the 
type, being known. This is found 
in the collection of the American 
Museum of Natural History in 
New York. The moth is pale 
rosy red in color, and marked as 
shown in the cut, which was drawn from the type by Mrs. 
Beutenmuller.
