THE CANADIAN ENTOMOLOGIST. 91 



I do not know that I can say any more on the subjects that we 

 have had under discussion. I trust that I have written with befitting 

 modesty, and that I have given the reasons for my statements with sufii- 

 cient clearness. After weighing all that has been written, I am convinced 

 that Hyphantria textor, Harris, is not one and the same with Bonibyx 

 ainea, Drury, and that the insect I have described as ainea more closely 

 corresponds to Drury's figure than any other moth, or any figure or 

 description that has come under my notice. 



NOTE ON CYANIRIS PSEUDARGIOLUS OF BOISDUVAL AND 



LE CONTE. 



BY ARTHUR G. BUTLER, PH. D., BRITISH MUSEUM, LONDON, ENGLAND. 



In 1782, Cramer described and figured a Cyaniris (PI. CCLXX., 

 figs. D, E), and incorrectly gave the Cape of Good Hope as its locality. 



In his " Rhopalocera Africse Australis," Mr. Trimen described the 

 species from a single example labelled " S. Africa " in the British Museum 

 collection, and stated that this was the only example he had seen. In 

 his later work this species is ignored, Mr. Trimen having evidently 

 satisfied himself that it never came from any part of Africa. On looking 

 up the authority for the locality of the specimen mentioned by Trimen in 

 our oldest " Register of Accessions," I find it entered as "P. Ladon, Cram., 

 n., S. Africa?" the locality having evidently been entered on Cramer's 

 authority. 



As a matter of fact, Cramer's insect is undoubtedly Cyaniris 

 pseudargioltts, which it necessarily supersedes, and our reputed African 

 example is a large specimen of the form marginata, rather less suffused 

 than usual on the under surface. 



It is always inconvenient to alter the names of well-known and 

 abundant species, but under the circumstances I do not see how it can 

 be avoided in the present instance : it will perhaps have one advantage — 

 as C. psendargiolus is not half so nearly related to C. argiolus as it is to 

 the Sikhim species, C. dilectus, an inappropriate name is suppressed.
