with pale yellow, the band of this color running out to nothing 

 before it quite reaches the apex. The specimen figured on 

 the plate came from Colorado. It is also said to occur in 

 Canada and the northern portions of the United States. 



Genus HYPOPREPIA Hubner 



A small genus of North American moths, all the species of 

 which occur within the territory covered by this book. The 

 insects closely resemble each other, and the student who has 

 learned to recognize one of them cannot fail to refer the others 

 correctly to their genus. It is not, however, so easy to discrimi- 

 nate the species. The following little key, which is taken from 

 Hampson's Catalogue, Vol. II, page 515, may help the student 

 in making correct specific references : 



1. Ground-color of the fore wing wholly scarlet miniata 



2. Ground-color of the fore wing yellow and crimson jucosa 



3. Ground-color of the fore and hind wings yellow cadaverosa 



4. Ground-color of the fore wing fuscous brown, of the hind 



wing whitish inculta

 (The Scarlet-winged Lichen-moth.) 



Syn. viltata Harris; subomata Neumcegen & Dyar. 



This rather common insect ranges from Canada to the 

 Carolinas and westward in the region of the Great Lakes to 

 Minnesota. It comes freely, as do all the species of the genus, to 

 light, and I have found it very abundant at times about the 

 lamps in the village of Saratoga, New York. I have taken it at 

 Asheville, North Carolina, and at the White Sulphur Springs in 

 West Virginia, but have never received specimens from low 

 altitudes on the Virginian and Carolinian coasts.

This species, which may be
