is different. We have here a common extra-mesial black line, and the 

 appearance is more Saturnia-like. Tliere are two spots on the cell of fore- 

 wings, while in Hemileuca we have only one. These characters are suffi- 

 cient for at least a subgeneric division, and I propose to call it 

 Argyrauges, from the sheeny white wings. While in Hemileuca the 

 colors are dull, in Argyrauges the fore wings especially are glossy and the 

 colors bright. In Argyrauges the wings seem a little broader and fuller, 

 but they hardly differ from Maia in this respect. The squamation of the 

 wings is of a different character. The neuration, so far as I can observe 

 it without denuding the wings, seems essentially the same in all these 

 forms. There is a tendency in Maia and Nevadensis to vary in a different 

 direction from the other forms. So far as I recollect, Dr. Hopffer's male 

 and female types from Texas, in the Imperial Museum at Berlin, his H. 

 Grotei, is more like Maia, though opaque, than the type of Yavapai. It 

 was the first of the species, allied to Maia, to be described. While Nroa- 

 densis seems to be hardly more than a variety of Maia, I have never seen 

 either ///«(? or Diana, but, from information, it seems likely that they are 

 the same. Is Diana not the same as Grotei 2

% . Fore wings blackish fuscous, very dark, with an even white stripe 

 from apex to middle of inner margin. Hind wings bright yellow in the 

 disk with a large ocellus like lo : the yellow field is confined by an outer 

 black line ; terminal field pale fuscous shaded. Size of H. Paviina or a 

 little larger, allied to it by the pale fawn abdomen shaded broadly above 

 with red. The male differs by the abdomen all red above. The base of 

 secondaries show longer pink red hairs. Beneath discolorous fuscous, with 

 white discal dots surrounded by black on primaries. Thorax fuscous ; 

 marked where the wing touches the sides with white. New Mexico. Prof

 Beneath primaries as above ; costa and apices yellow, strigate with red ; a
