in the typical C. Barbara, but one of the females from Colville 

 Valley is nearly like it. Mr. Scudder remarks very justly that the 

 specimens can not belong to C. Pelidne and brings them as variety 

 to Philodice, with which I would directly agree, except for the 

 impossibility to separate it from C. Harfordii. Mr. H. Edwards 

 considers them to be a species, as also the author of the Brooklyn 

 Bulletin. Mr. W. H. Edwards in his Synopsis (1882) has placed 

 C. Laurentina as var. of C. interior. C. Harfordii and'C. Laurentia 



i 



seem by the shape and color of the upperside to be nearly related 

 to C. Philodice, but otherwise to belong to C. Edwardsii = C. 

 interior. Till the contrary has been proved, they should be so 

 placed. 



Colias Philodice. 



Fifty specimens selected out of a much larger number for the 

 collection of the Museum represent the Atlantic States from 

 Canada to Maryland ; the northern border to Michigan and to 

 West Dakota ; and in the interior, Missouri, Kentucky, West 

 Virginia, Kansas, Texas. Some are determined by Mr. W. H. 

 Edwards. From Dallas, Texas, Mr. Boll had sent six specimens 

 with the note " some collected in March, the other larger and 

 more common in September and October." Those specimens 

 have been examined by Mr. W. H. Edwards ; two small males 

 are marked in his handwriting var. Philodice ; the larger ones 

 $ 9 differ in nothing from the larger Philodice ; the smaller ones 

 t 9 have a narrower marginal band of the primaries and mimic 

 well C. Ariadne. Mr. Reakirt, Proc. Ent. Soc. Phil. Vol. iv, p. 

 218, has given a detailed description of C. Philodice and varieties. 



Mr. W. H. Edwards has published (Vol. n, N". A. Butt.) a very 

 elaborate and excellent paper about this species. The exposition 

 of the numerous variations in color and pattern is decidedly 

 exhaustive. In an equally detailed paper on C. eurytheme in the 

 same volume he comes to the conclusion, that both species have 

 exactly the same variations and only differ by color. " The 

 larvae are scarcely, if at all distinguishable in the earlier stages, 

 and in the later are often just as much alike." If those two 

 papers are to be considered as the standard from which all the 

 other described species have to be judged — and they merit fully
