is well known from South America. His figures, moreover, though 

 apparently illustrating a typical Pero, do nol represent any form 

 known to me from North America. In build, shape, and markings 

 it resembles most nearly our marmoratus, but docs not have the blotch 

 just outside the outer line on the primaries so characteristic in that 

 species, and is suffused with a crimson tint— a character possessed 

 by none of our species in the slightest degree. 



Peplaria, which, according to our catalogue, is the next oldest 

 name for the species, was also used by Hubner in his Zutrage. His 

 figures (709, 710) represent both upper and under surfaces, and 

 though we have his statement that the species comes from North 

 America, I know of nothing in our fauna that approaches it. Cer- 

 tainly it is not the form to which Hulst applied the name. It prob- 

 ably is congeneric with the species listed in our fauna under Sfen- 

 aspilates, though from the female (which sex alone is depicted) this 

 can not be said with absolute certainty. The course of the extra- 

 discal line of both wings is peculiar, the sharp angle in that of the 

 secondaries being especially characteristic, while the yellowish color 

 of the under side of the wings is unique, reminding one of certain of 

 our Gonodontis species. 



Hubneraria Guenee a is another name for Hiibner's ancetaria, the 

 author discovering the distinctness of the latter species from anceta 

 Cramer and rightly renaming it. 



Honestaria Walker is the first valid name for our North American 

 species. The measurement he gives seems small, but Mr. Prout 

 assures me that it is identical with American specimens sent him for 

 comparison. 



Stygiaria Walker is apparently a typical male of honestarius. 



Packard, in his monograph, mixes specimens of what is undoubt- 

 edly peplar'i aides with honestarius, but refers to them in the remarks 

 following his description as being larger in expanse of wings. 



Drucesays that Central American specimens of hubneraria ( — hones- 

 tarius) are usually darker than those from the United States. It 

 is probable that Mr. Druce did not have the true honestarius before 

 him, as on the same page he lists honestarius as a separate species, 

 remarking that the specimens of this latter species are almost identical 

 with Walker's type. 



Lastly, I have excluded atrocolorata Hulst from the synonymy. 

 This was described'' as a variety of Azelina hubnerata from seven 

 examples. Of these types I have located only four, two in the 

 Brooklyn Institute Museum and two in his own collection at .Vu 

 Brunswick. Three are typical honestarius, but the fourth, a female 

 from Florida, is a totally different species with the genera] aspect of a
