Habitat. — Mendocino County, north of Mendocino city, California

Genus HOMONYMUS Walsingham. 

 HOMONYMUS COLORADELLUS, new species. 



Antennx cinereous. 



Palpi erect, reaching scarcely above the base of the antennge, 

 thickly clothed throughout; mixed brownish ocherous and brown- 

 ish fuscous, appearing slightly paler than the head and thorax above 

 and below them. 



Head and tliorax are brownish fuscous, the scales tipped with 

 hoary gray. 



Forewings rather narrow, of about equal width throughout, ex- 

 cept at the extreme base, the width equal about one-third the 

 length, termen slightly convex, oblique, apex rounded. 



Neuration 12 veins, all separate; dull cinereous, with some paler 

 hoary patches running along the fold to the end of the cell, thickly 

 sprinkled throughout with brownish ocherous and dark fuscous 

 scales which are concentrated in some small patches, one at the end 

 of the cell, one on, and on 3 immediately above the fold beyond it, 

 with a series of very obscure costal spots; cilia brownish fuscous, 

 slight]}^ paler along their base and mixed with brownish ocherous 

 about the tornus; underside uniformly brownish fuscous, with nar- 

 rowly pale margins. 



Alar expanse. — 24 mm. 



Hindwings, 8 veins, all separate; slightly wider than the forewings; 

 brownish fuscous; cilia with some paler markings. 



Ahdomen (missing). 



Legs brownish fuscous. 



Type. — Male (Walsingham determined, No. 4749, 1906), Cat. No. 

 10360, U.S.N.M. 



Habitat.— Custer County, Westcliff, Colorado. (Collection Beuten- 

 miiller). Unique. 



This agrees with the genus Homonymus, described from South 

 America, but differs from the only species at present known in its 

 shorter palpi and by the absence of deep purple coloring in the 

 hindwings, as well as by the somewhat different pattern of the ob- 

 scure markings on the forewings.
