VAGRANT EUPITHECIAS. 



[Lepidoptera; Geometridae.] 

 BY RICHARD F. PEARSALL, Brooklyn, N. Y. 



Some time ago, through the courtesy of Dr. Harrison G. 

 Dyar, there was entrusted to me some specimens from the 

 collection of the U. S. National Museum, belonging to the 

 geometric! genus Enpithecia and allies, for study and arrange- 

 ment. At that time the identity of even our commoner species 

 was in doubt, and the types of other described forms, without 

 seeming complement among this material, ought to have sug- 

 gested how much labor must be bestowed upon this group 

 before they could be intelligently assigned to positions of per- 

 manency. A large number of new species were being de- 

 scribed from the Western States, from Canada, and from Brit- 

 ish Columbia by Mr. George W. Taylor, whose types were 

 practically inaccessible for reference, owing to their distant 

 location, and while I believe I have been able to identify some 

 of these correctly it would not be surprising if other forms I 

 have here described prove synonyms of some of his species. 

 Even with this possibility it was deemed better to attach 

 names to those distinct forms which I have separated. 



The results as given seem meager indeed, compared with 

 the labor expended, except as a contribution of larger knowl- 

 edge to the writer and the opportunity it affords him to ex- 

 press a grateful recognition of the kindly forbearance shown 

 him during the long period the material has remained in his 

 possession.
